@@nicknorwitzPhD Just make sure to consume plenty of glycine, all those phenols in your foods are converted to benzoic acid which then is combined with gycine for clearance.

I lost 150lbs and it took me 2 years. From 320lbs to 170lbs. I’ve maintained it for 5 years now. And I’m now 64 years old, suffer from Hemochromatosis, and had my aortic valve replaced 2 years ago. I drank green tea, and still do, all through these years. I drank no coffee. I hardly exercised due to the damage that hemochromatosis has done to my joints. I can only take a casual 20-minute walk everyday.
Isn't hemochromatosis excess iron in blood??? Maybe listen to Morley Robbins, he has many videos on utube about iron/copper/ceruloplasmin. He may help u to understand why this happens and what to do about it. Good luck.

@MiDnYTe25 there are no bad and good cholesterol variants.

Wow!! Good one! I appreciate the work, insight, and production value that goes into your videos. As someone who dabbles in making similar content, I really respect your work. Thank you!
I appreciate that you take the low carb factor into account. However, what you mentioned are all high-oxalate foods, which can contribute to joint and bowel inflammation, skin issues, kidneystones and calcium deficiency in bones. I have had the best results excluding almost all plant material from my diet except coconutcream, coffee, tea once or twice a day and olive oil. Every now and then adding a bit of vegetables or very little amounts of lentils, buckwheat, wheat or rye flour, so carbs stay under 20 g.
It helps to wrap oxalate foods into high calcium containing foods. Example, eating your high-oxalate walnuts in whole milk Greek yogurt. One can also benefit by soaking your walnuts in warm water overnight, then rinsing before eating. Agree with you though, high oxalate foods can be dangerous to consume if not careful. Est them in moderation, and some people probably should avoid them as much as possible and go with another option.
I agree! And I suspect some spicy comments on this one, given the skew of these diets towards MUFA/PUFA. That said, bear in mind, if both low-carb diets had similar fat profiles it doesn't make any claims on the superiority/inferiority of plant/animal fat.

I've tried to feed grass to my cheddar, but somehow it just sits there, seems uninterested. 😁😏 PS In the old days (1800s) there were critters in cheese called cheese hoppers - a delicacy, apparently. Very cheesy little mites. But you had to catch em as they escaped. 🫤 I've now looked them up. Tyrophagus casei. So cute!
I eat blueberries, kefir and macadamia nuts every day. I Drink green tea a few times a week. I carry zero viseral fat. Cheers for the video explaining why it works. Appreciated
Most days I will eat a half a bowl full of yogurt, Kefir, or skyr, with pecans, macadamia nuts, sprouted walnuts, and pumpkin, flax, and hemp seeds. I am glad to hear several of those ingredients mentioned in this episode.
I have Heard that IS not a good ideia tô mix diferente NUTS, not tô mix diferent seeds, for our body to better absorb and utilize, is best to eat ONE type at a time
"Visceral Fat is the worst type of fat" - no, hepatic fat is even worse. And this mantra that "visceral fat is proinflammatory" is also only a half-truth. The problem is GETTING FAT due to high insulin. Then, adipocytes start to burst because these take up more fat than what these can handle. And that is an injury which needs repair which obviously is pro-inflammatory. But just HAVING FAT is by itself NOT pro-inflammatory. The proof is: If you start losing weight, the inflammation goes down very rapidly even if you haven't lose a significant amount of fat YET. And this is true for any adipose tissue...
Too fat is too fat, that is simply bad. Lots of science to back it up. Some people however can carry a lot of fat in a relatively healthy manner - under skin. Others, not so. Having excess fat is, on several levels, pro inflammatory (decreased blood circulation around tissues, storage of toxins, pro inflammatory hormone signaling) - with or without insulin. Insulin resistance makes matters much worse, of course, compounding the effect.
@@Ruudwardt "Too fat is too fat, that is simply bad." Myth. "Lots of science to back it up." Lot of "science" is crap. "Having excess fat is, on several levels, pro inflammatory" False. Having high insulin is pro-inflammatory...
@@btudrus Where do you get that insulin is pro inflammatory? Depending on context it can have one or the other role. Insulin resistance makes for nice pro inflammatory environment, and the resulting high insulin is more of a symptom than cause. Excess fat is environment for insulin resistance. Deduce away.. How do you back up your 'facts' then, if not with science (or other data based analysis)? Never heard of adipocytes that burst. Did you just make this up?
Keto diet is becoming a political topic for the Left lining crowds. Dr.Ekberg, Dr.Berg, and other advocates of low carb diets are censored by RUclips, Meta, and Google.😢
It's a great pity that a pure carnivore diet wasn't included. Who knows whether the gut bacteria a carnivore diet supports ( which has been shown to be highly varied and associated with superior health outcomes ) may lead to an even greater visceral fat loss than the green tea/ duck week med diet?
@nicknorwitzPhD thanks for your reply. It would be fantastic if Dave Feldman could include such a carnivore v green tea/ duck weed trial (effect of visceral fat levels ) on his citizen science trials to fund/do list!
Love the new set/delivery. Question- was the hydration kept consistent across all diets - because if not, could the green tea drinkers just be more hydrated? (Drinking water assists with weight loss no? )
Did the study specify a dosage on the Duckweed? All I saw was 100g/day for the duckweed in a google search. That's almost the entire can that they sell on Amazon
Did this trial measure both visceral fat and subcutaneous fat during the trial to show if one was reduced/targeted more than the other in each of the diet?
Interesting that you did not mention cocoa, which is also very high in tannins (perhaps the wrong kind of tannins?). I am extremely sensitive to tannins - especially black tea, but also green tea and cocoa. They cause me severe constipation. I have had this issue all my life. So no green tea for me... But plenty of fermented cheese 🤗
Unfortunately they do not sell the Frozen Mankai cubes anymore because the company stopped producing it. I do drink RISHI brand Green Tea and make my own SIBO full fat yogurt... So Im down with as much of this as possible. Was thinking of just getting a mess load of the little plants, but not sure how that would work out putting them in my tea as is.
Would decaffeinated green tea still have the same compounds needed to get the health benefits? Also any specifics on the type of green tea? I know a lot of supermarket teas aren't really matcha or contain a really small amount of matcha - does it make a difference? And there is also matcha vs. sencha, etc.
I've recently found that food high in polyphenols were seemingly causing the weird focus/brain fog issues I've been having. It's really annoying, since I love matcha, berries, chocolate, cranberry juice ... I'm pretty sure it's a microbiome issue, but it's tough to solve.
This is interesting. Duckweed is the 1 plant that took me over a YEAR to remove completely from my aquarium. It's so annoying -- I could see why they want to use it in space. It reproduces so insanely quickly. It's a nightmare. Almost impossible to kill/get rid of. Eating it? Not sure I'd do that. Any idea what the Oxalate content is of duckweed? I don't think I'd risk a kidney stone/anti-nutrient from it. Green Tea seems legit though. Drinking 1 glass a day recently. Any more than that seems to introduce a moderate amount of oxalates.
I had already watched a similar video discussing the findings of this study and somehow ended up with the main takeaways: green tea and micro greens. I'm not sure how close duckweed and microgreens are...maybe I looked up polyphenolic properties since I haven't seen 'duckweed' in my local produce section? I don't know for sure but I've been putting microgreens on everything of late just to cover the bases...lol! Another great video!
green tea or tea in general (not herbal tea that does not contain the tea leaves) has been increasingly indicated to be associated with other conditions. If fat loss is the only metric then sure it might be beneficial on a 'lowish' carb med diets. Outside of that is it really worth it?
green tea. Its probably one factor in why people in Japan are in general healthier with one of the highest life expectancies in the world. You should repeat your Oreo N of one study on a lean mass hyper responder without a intestinal disease. I bet you the results will be quite different.
@phyju cal restriction is not a thing. There is at least one vidéo from Nick about it. Moreover those are not cal restrictive diet, you eat when you're hungry until you're not anymore.
My #1 go-to for health content and answers. A question: What strains of gut critters produce hippuric acid and urolithin A? Also, am I correct in thinking that moderation by tea is better than higher dose supplementation if there is such a thing? I guess you answered this question. (Pee-kans! You crack me up.)
Watching as I drink my first cup of green tea. You mentioned at the end specifically loose-leaf green tea. Is there a difference between that and what is found in the green tea sachets I can buy off the shelf at the grocery? Also, do we know how much wolfia globosa was being consumed in the study? Sorry if either of those were explained in the video and I missed it. Thanks as always!
If you compare loose leaf tea to what's in a tea bag, the loose leaf stuff is a much better, higher quality product...!!! And the concern with tea bags is that you might be ingesting microplastics yuck 🤢
@@bobwilkerson9760 what if i cut the tea bag and brew the tea without it instead? can it be done that way? or the microplastic is already in the grounded tea?
Unfortunately Mankai is no longer available in the USA. It used to be sold in frozen cubes and I’d add it to my smoothie. There wasn’t enough interest in the USA so they stopped selling it here. Big bummer.
Great video as usual Nick. I would like to point out one caveat with respect to the consumption of green and black tea. I love and drink green tea every day. However, the tea plant (Camellia Sinensis) is known to be a hyperaccumulator of fluoride and fluoride is delivered to the final brew of tea. As I'm sure you must know, long term fluoride intake is associated with multiple negative health outcomes. I've collected 14 studies on this issue and there are many more. I therefore believe that black or green tea consumption should be somewhat tempered. For instance, drinking one liter or more of tea daily, 4 or 5 cups depending on the cup size and tea type/brand, can put one over the tolerable upper intake level for fluoride of 7 mg/day for adults. Furthermore, if one lives in a municipality where water fluoration is practiced, this further exacerbates the situation. And finally, one musn't forget that the vast majority of people use toothpaste that contains fluoride further compounding the problem.
Sodium fluoride vs calcium fluoride. Also, the body has a use for all elements in nature except aluminum. Your body does need fluoride and in a natural form like this, your body can distinguish BETTER between it and other things. In the natural form it's bundled with other things that make it easier for the body to choose to intake it or discard it as waste. The charge of particles also matter and in the natural form, is ideal. If you isolate compounds from nature I'm sorry to say, you'll find they all have necessary use in the body to prevent bad health. It is the second most stored micro mineral in the body responsible for the elasticity of tissues, tendons, ligaments, skin, etc, your heart would be unable to beat without it.
Nope. Fluoride had been consistently shown to be safe at concentrations most people experience, outside of rare hyper exposure groups. If you read the literature properly and slid cherry picking the few studies which seem to support your favourites conclusion, it will become clear.
Thanks for this video! I’m skinny fat. All my fat is below my breast and stomach. I eat healthy exercise etc. I would like to try the Mankai since nothing else has worked. Do you know where we can buy it? And which brand would you recommend? Ty ty

Bro 100g/day of wolffia globosa duckweed...the 3/4 cups a day of green tea is practical with my costco card but this wolffia globosa duckweed is not cheap...is the juice worth the squeeze
@ There may be factors like age at play in that response. As an older man, achieving six-pack abs is definitely more challenging.😂🤣 thinner DaD bod would probably be the norm 😜
Interesting! I wonder, when they say they included 4 cups or so of green tea, if they also added 4 cups of water to the control diet to control for any of possible effects of extra fluid intake.
I'm not falling for it. Not enough studies or proof. Plants have oxalates and other antinutrients. Tell me what the side effects were in this study please.
Too many WAGs here. Too many alternatives. Too much speculation, especially in the sense that the specific compounds are beneficial overall. How do you know some, or all, of them are not stressful for the body, hence causing an increase in metabolic stress that leads to burning more calories? How do you know you are not feeding species in the biome that are poor contributors to overall health? How do you know...
The isocaloric part of the study seems to only be verifiable at the design/start of the study? Seeing as the participants had less and less checkins as the months went on. It also involved a self report food questionaaire with 127 items on it. How can we rule out the possibility that the the greenmed dieters weren't just eating less calories because of the reduced red meat consumption they were instructed to adhere to coupled with potentially crushing their appetite with 3-4 topups of caffeine?
For an 18 month free living study it's difficult to make it a feeding study. It's possible, in theory, but with an insane price tag at 200-300 people. Thus, it's true there are certain things that can't be strictly controlled; however, the randomization should help account/compensate for this. Another question to ask is why would the Green Med dieters, as a population, have a biased self-report vs the other groups? Also note that both low-carb groups had similar "other" instructions re red meat/cholesterol etc. So, unless it was the tea and/or duckweed that causatively led to reduction in intake of X, Y Z...
@nicknorwitzPhD Nick, how do we separate out "combined with sensible diet and exercise" from the results and know the true effect of the tested theory, in this or any test involving weight loss???
More on the magic of microbiome-produced metabolites, please! So interesting with the "Mediterranean diet", which I'd associate with loads of bread, pizza, pasta, potatoes, albeit freshly produced, served and enjoyed with much love, cheese and delicious sauce
Med diet is more about loads of olive oil, sardines, fish, pork, beef, etc. They will serve on the side bread and potatoes. Pizza and pasta came later in history and aren't eaten very often by the long-lived natives of the area.
Thank you for the awesome video Dr Norowitz! I have an upcoming Dexa scan in Cambridge to establish some baselines. If we were interested in adding Wolffia Globosa to our diets, where might we find it? I've only seen Wolffia Globosa supplement powders on Amazon and I can't imagine that would have the same impact? Thank you again!
Nick thank you for providing this type of content! I have had a DNA test by 10x health and one of the results is double bad COMT gene, with recommendation to avoid green tea because it said it may worsen COMT symptoms. I am 64 and just a bit overweight, several years ago I changed my diet and lost 50 lbs and have kept it off however I am stuck at new body weight point with more weight to lose. I'm looking for a strategy to reduce visceral fat. Please comment
n = 286. 90% retention at 18 months. Starting BMI 31.2 in all groups. All baseline characteristic re in Table 1. Quite similar. Feel free to look. It was a free living RCT, given the duration of the study. The assumption is one does not need to "control" for things like step count since the randomized should eliminate that as a confounder.
The conclusion of the study adds in reduction in red/processed meat as well as the variables you mentioned. Did the study tease out processed vs not process red meat? I do not understand lumping those things together, apples and oranges as my Algebra teacher used to say.
No it didn’t. I also don’t necessarily agree with that conclusion based on the presented data. It also wasn’t a between group difference, more of a background factor common across groups.
Green tea contains caffeine. 4 cups would equate to 200 mg caffeine. Caffeine makes people move more and have higher heart rates. Were calories equated for the extra calories burned whith this? They should do a rhcc with a group with plain caffeine as well
Well, I’m in that camp. I think a very low carb diet with or without fasting likely is even more potent than the green med diet described. That’s speculation. I don’t have head to head tests. Works for me. Also decaf green tea should have a similar effect
why in the world would a study put in 2 variables and not just 1 at a time? We have no way to know which variable caused the results, how do we know if 2 variables together had a synergistic effect or not.
The wolfia plant is one of the common plants fish hobbyists and fish breeders feed to their fish in southeast Asia. I used to keep wolfia to feed my goldfish. They are so easy to grow.
Your videos are always interesting, thank you for this shared work. We must also consider hormones, if we are a woman or a man and hormonal age I think. When I was younger I ate a lot and I didn't gain too much weight. now it's hard. I am very very sporty (>12h/week of fight’s sports) and >50 years old. I eat very well. No classic diet I follow to lose ten extra pounds. and I know nutrition well. I tried the ketogenic diet, the Mediterranean diet and the carnivore diet. The low calorie strict carnivore is what works best for me. When I'm not on a diet, I naturally eat a lot of organic peanut butter, nuts from my garden, cheese aged in raw milk (I live in France), and a lot of meat, and have been doing so for years. Espresso coffee and green tea every day. This diet suits me perfectly for my health, to perform in my combat sports, but unfortunately not to lose weight. Even when I do intense sports weekends like 8 hours a day, I don't lose a single gram. On the other hand, I'm gaining muscle and getting leaner, I'm losing water I think, which helps a little. The ONLY method that works for me, a postmenopausal woman, is when I stick to a VERY low-calorie diet, taking into account that I also do two hours of sport every day. To lose weight I must be hungry and limit myself to 1200kcal per day. I believe that genetics determines a lot. being able to store is good for survival, but not for our aesthetic desires. The best proven method that makes me lose weight is a very hypocaloric carnivore diet (very important because Dr Dagostino says that carnivore not associated with hypocaloric diet makes you age, be careful), a low-carb diet (just enough to practice my sports, i.e. the equivalent of two large fruits per day) you also need omega 3 (a tablespoon of canned cod liver and its oil), practice intermittent fasting (I don't eat before 12am), miso broth, fish, beef, fatty veal, fish fillets, very few green vegetables (I can't digest them anymore unfortunately), two kiwis, or a grapefruit, a little kefir . And no nuts. even macadamia. Every time I return to the usual diet with lots of nuts, even when controlling calorie intake, I gain weight or I don't lose, but on the other hand I feel super fit on a daily basis and for sport. Health diet and weight loss diet are two different things.
I really enjoy and value how you explain your ideas. I often skip what people say in these videos but your explanations are so clear and compelling that I can only stay and listen. Thank you!

How do you know you have zero visceral fat ? MRI? DEXA scan? Or something else?
Is there even a cheap way to measure visceral fat?
MRI supposedly is effective.
@@petermadany2779 @emiki6 pinch test. You will know convincingly when you have zero or close to it. Abdominal muscles cannot be seen with it there.
1:55 min Green Mediterranean diet consists of Mankai Duckweed (Wolfia Globosa) and green tea.
Most days I will eat a half a bowl full of yogurt, Kefir, or skyr, with pecans, macadamia nuts, sprouted walnuts, and pumpkin, flax, and hemp seeds. I am glad to hear several of those ingredients mentioned in this episode.
When you say bowl, is that a large mixing bowl?, or what...
It's seems you're overdosing on calories. I am joking. Nuts are good for you.
@@tlots2345 I am unsure what the bowl is called, but I put about 1 cup (8 oz) of ingredients in it.
@@kotenoklelu3471 😁Instead of calories, my goal is to limit net carbs. The nuts I select don't have many net carbs.
I have Heard that IS not a good ideia tô mix diferente NUTS, not tô mix diferent seeds, for our body to better absorb and utilize, is best to eat ONE type at a time
Thank you Nick! I subbed on the last video of yours. Great information I am using from this point forward❤
Thank you! Hope you enjoy what's to come!
8:30 min why would you want to get your Urolithin A from tea when pomegranates have the highest levels of Urolithin A?
"Visceral Fat is the worst type of fat" - no, hepatic fat is even worse.
And this mantra that "visceral fat is proinflammatory" is also only a half-truth.
The problem is GETTING FAT due to high insulin. Then, adipocytes start to burst because these take up more fat than what these can handle. And that is an injury which needs repair which obviously is pro-inflammatory.
But just HAVING FAT is by itself NOT pro-inflammatory. The proof is: If you start losing weight, the inflammation goes down very rapidly even if you haven't lose a significant amount of fat YET. And this is true for any adipose tissue...
Splitting hairs at its finest. 😉
I found this very informative. Thanks.
Too fat is too fat, that is simply bad. Lots of science to back it up.
Some people however can carry a lot of fat in a relatively healthy manner - under skin. Others, not so.
Having excess fat is, on several levels, pro inflammatory (decreased blood circulation around tissues, storage of toxins, pro inflammatory hormone signaling) - with or without insulin. Insulin resistance makes matters much worse, of course, compounding the effect.
@@Ruudwardt "Too fat is too fat, that is simply bad."
Myth.
"Lots of science to back it up."
Lot of "science" is crap.
"Having excess fat is, on several levels, pro inflammatory"
False.
Having high insulin is pro-inflammatory...
@@btudrus Where do you get that insulin is pro inflammatory? Depending on context it can have one or the other role. Insulin resistance makes for nice pro inflammatory environment, and the resulting high insulin is more of a symptom than cause.
Excess fat is environment for insulin resistance. Deduce away..
How do you back up your 'facts' then, if not with science (or other data based analysis)? Never heard of adipocytes that burst. Did you just make this up?
It's a shame the study didn't include a zero or ultra low carb diet too, I suspect that might have been even more effective for visceral fat loss.
I wasn’t consulted at the design phase
@@nicknorwitzPhD Thus showing their lack of meticulousness
Keto diet is becoming a political topic for the Left lining crowds. Dr.Ekberg, Dr.Berg, and other advocates of low carb diets are censored by RUclips, Meta, and Google.😢
It's a great pity that a pure carnivore diet wasn't included. Who knows whether the gut bacteria a carnivore diet supports ( which has been shown to be highly varied and associated with superior health outcomes ) may lead to an even greater visceral fat loss than the green tea/ duck week med diet?
It's possible... would love to see that study! Will have more to say on Carnivore in the coming months...
@@nicknorwitzPhDwink wink
@nicknorwitzPhD thanks for your reply. It would be fantastic if Dave Feldman could include such a carnivore v green tea/ duck weed trial (effect of visceral fat levels ) on his citizen science trials to fund/do list!
@nicknorwitzPhD .... and I look forward to hearing what you will be saying about carnivore!
Lack of fibre in Carnivore diet can't be good for a healthy diverse gut flora needed
Another excellent video. I may try an n=1 test of this, assuming I can find Duckweed in my local grocery space vegetable section.
Love the new set/delivery. Question- was the hydration kept consistent across all diets - because if not, could the green tea drinkers just be more hydrated? (Drinking water assists with weight loss no? )
Did the study specify a dosage on the Duckweed? All I saw was 100g/day for the duckweed in a google search. That's almost the entire can that they sell on Amazon
gross
I'm wondering if Chlorella Spirulina would function similarly as the Duckweed w/o the 'clone' or space factor. 🤔
Did this trial measure both visceral fat and subcutaneous fat during the trial to show if one was reduced/targeted more than the other in each of the diet?
Interesting that you did not mention cocoa, which is also very high in tannins (perhaps the wrong kind of tannins?).
I am extremely sensitive to tannins - especially black tea, but also green tea and cocoa. They cause me severe constipation. I have had this issue all my life. So no green tea for me...
But plenty of fermented cheese 🤗
Different tannins.
@nicknorwitzPhD Good to know 👍
Unfortunately they do not sell the Frozen Mankai cubes anymore because the company stopped producing it. I do drink RISHI brand Green Tea and make my own SIBO full fat yogurt... So Im down with as much of this as possible. Was thinking of just getting a mess load of the little plants, but not sure how that would work out putting them in my tea as is.
Would decaffeinated green tea still have the same compounds needed to get the health benefits? Also any specifics on the type of green tea? I know a lot of supermarket teas aren't really matcha or contain a really small amount of matcha - does it make a difference? And there is also matcha vs. sencha, etc.
Yes, but caffeine is also very good for you
I've recently found that food high in polyphenols were seemingly causing the weird focus/brain fog issues I've been having. It's really annoying, since I love matcha, berries, chocolate, cranberry juice ... I'm pretty sure it's a microbiome issue, but it's tough to solve.
This is interesting. Duckweed is the 1 plant that took me over a YEAR to remove completely from my aquarium. It's so annoying -- I could see why they want to use it in space. It reproduces so insanely quickly. It's a nightmare. Almost impossible to kill/get rid of.
Eating it? Not sure I'd do that. Any idea what the Oxalate content is of duckweed? I don't think I'd risk a kidney stone/anti-nutrient from it. Green Tea seems legit though. Drinking 1 glass a day recently. Any more than that seems to introduce a moderate amount of oxalates.
Personally, I'm enjoying Green tea, not duckweed, albeit for other reasons. Funny story about the aquarium
Where can you get Wolffia globosa and how to consume it?
How was visceral fat loss determined?
Mri scan before and after the 18 months?
Yes, MRI.
Would be nice to see before and after Mri images.
@@Raxados 3:23
I had already watched a similar video discussing the findings of this study and somehow ended up with the main takeaways: green tea and micro greens. I'm not sure how close duckweed and microgreens are...maybe I looked up polyphenolic properties since I haven't seen 'duckweed' in my local produce section? I don't know for sure but I've been putting microgreens on everything of late just to cover the bases...lol! Another great video!
Wolffia globosa is impossible to find online. What would be the best alternative?
green tea or tea in general (not herbal tea that does not contain the tea leaves) has been increasingly indicated to be associated with other conditions. If fat loss is the only metric then sure it might be beneficial on a 'lowish' carb med diets. Outside of that is it really worth it?
green tea. Its probably one factor in why people in Japan are in general healthier with one of the highest life expectancies in the world. You should repeat your Oreo N of one study on a lean mass hyper responder without a intestinal disease. I bet you the results will be quite different.
Is there any easy way to tell if the weight around your middle is subcutaneous or visceral w/o a MRI?
If it jiggles is SubQ.
Is this true for all/any type of green tea?
Only 14% reduction in 18 months seems a super low rate. Looking forward to see this study with keto / carnivore diet, I bet it will be way faster.
@phyju cal restriction is not a thing. There is at least one vidéo from Nick about it. Moreover those are not cal restrictive diet, you eat when you're hungry until you're not anymore.
My #1 go-to for health content and answers. A question:
What strains of gut critters produce hippuric acid and urolithin A?
Also, am I correct in thinking that moderation by tea is better than higher dose supplementation if there is such a thing? I guess you answered this question.
(Pee-kans! You crack me up.)
beard looking sharp my dude!
Cheers
Watching as I drink my first cup of green tea. You mentioned at the end specifically loose-leaf green tea. Is there a difference between that and what is found in the green tea sachets I can buy off the shelf at the grocery? Also, do we know how much wolfia globosa was being consumed in the study? Sorry if either of those were explained in the video and I missed it. Thanks as always!
If you compare loose leaf tea to what's in a tea bag, the loose leaf stuff is a much better, higher quality product...!!! And the concern with tea bags is that you might be ingesting microplastics yuck 🤢
@@bobwilkerson9760 what if i cut the tea bag and brew the tea without it instead? can it be done that way? or the microplastic is already in the grounded tea?
Are you keen to try green tea + Duckweed? Do you think this would affect your sensible gut problems?
Unfortunately Mankai is no longer available in the USA. It used to be sold in frozen cubes and I’d add it to my smoothie. There wasn’t enough interest in the USA so they stopped selling it here. Big bummer.
Great video as usual Nick. I would like to point out one caveat with respect to the consumption of green and black tea. I love and drink green tea every day. However, the tea plant (Camellia Sinensis) is known to be a hyperaccumulator of fluoride and fluoride is delivered to the final brew of tea. As I'm sure you must know, long term fluoride intake is associated with multiple negative health outcomes. I've collected 14 studies on this issue and there are many more. I therefore believe that black or green tea consumption should be somewhat tempered. For instance, drinking one liter or more of tea daily, 4 or 5 cups depending on the cup size and tea type/brand, can put one over the tolerable upper intake level for fluoride of 7 mg/day for adults. Furthermore, if one lives in a municipality where water fluoration is practiced, this further exacerbates the situation. And finally, one musn't forget that the vast majority of people use toothpaste that contains fluoride further compounding the problem.
Sodium fluoride vs calcium fluoride. Also, the body has a use for all elements in nature except aluminum. Your body does need fluoride and in a natural form like this, your body can distinguish BETTER between it and other things. In the natural form it's bundled with other things that make it easier for the body to choose to intake it or discard it as waste. The charge of particles also matter and in the natural form, is ideal. If you isolate compounds from nature I'm sorry to say, you'll find they all have necessary use in the body to prevent bad health. It is the second most stored micro mineral in the body responsible for the elasticity of tissues, tendons, ligaments, skin, etc, your heart would be unable to beat without it.
In seawater fluoride concentrations are 1.2 to 1.5 mg/litre. I wonder how much of that is absorbed transdermally by swimmers and divers.
Oxalates are even worse.
Nope.
Fluoride had been consistently shown to be safe at concentrations most people experience, outside of rare hyper exposure groups.
If you read the literature properly and slid cherry picking the few studies which seem to support your favourites conclusion, it will become clear.
Great information. Thanks as always!
Thank you for watching
You bet!
Thanks for this video! I’m skinny fat. All my fat is below my breast and stomach. I eat healthy exercise etc. I would like to try the Mankai since nothing else has worked. Do you know where we can buy it? And which brand would you recommend? Ty ty
@nicknorwitzPhD
what would you think of Green Tea with Allulose sipped throughout the day on a carnivore diet?
Where can you buy duckweed?
excellent information. would decaf green tea work as well do you know? thank you.
Yes it should be similar
@@nicknorwitzPhD thank you. Nick do you know if taking a pcsk9 inhibitor is indicated for someone who may have familiar hypercholesteremia and ho had very negative reaction to statins? thanks again.
Bro 100g/day of wolffia globosa duckweed...the 3/4 cups a day of green tea is practical with my costco card but this wolffia globosa duckweed is not cheap...is the juice worth the squeeze
Wait!! I want the Thor six pack!! Duck duck six pack 😂🤣 Great info Nick
Duck duck six pack sounds like a fun game... if you don't get "ducked" do you end up with a dad bod?
@ There may be factors like age at play in that response. As an older man, achieving six-pack abs is definitely more challenging.😂🤣 thinner DaD bod would probably be the norm 😜
Does matcha suffice as green tea? I like to put matcha powder in my fruit smoothies!
Interesting! I wonder, when they say they included 4 cups or so of green tea, if they also added 4 cups of water to the control diet to control for any of possible effects of extra fluid intake.
I see duckweed is high in B12. It might be Interesting to compare this cohort by MTHFR status. Is alcohol B12 depletion a factor in beer belly?
I'm not falling for it. Not enough studies or proof. Plants have oxalates and other antinutrients. Tell me what the side effects were in this study please.
Great stuff, Stayin' curious
Too many WAGs here. Too many alternatives. Too much speculation, especially in the sense that the specific compounds are beneficial overall. How do you know some, or all, of them are not stressful for the body, hence causing an increase in metabolic stress that leads to burning more calories? How do you know you are not feeding species in the biome that are poor contributors to overall health? How do you know...
Yea, and what if the sky is falling and what if is not…
What do you think of Urolithin A supplements?
TBH, I wouldn't, personally. There's a sweet spot for these things.
@ but what if you don’t have the microbiome to produce Urolithin A on your own?
The isocaloric part of the study seems to only be verifiable at the design/start of the study? Seeing as the participants had less and less checkins as the months went on. It also involved a self report food questionaaire with 127 items on it. How can we rule out the possibility that the the greenmed dieters weren't just eating less calories because of the reduced red meat consumption they were instructed to adhere to coupled with potentially crushing their appetite with 3-4 topups of caffeine?
For an 18 month free living study it's difficult to make it a feeding study. It's possible, in theory, but with an insane price tag at 200-300 people. Thus, it's true there are certain things that can't be strictly controlled; however, the randomization should help account/compensate for this. Another question to ask is why would the Green Med dieters, as a population, have a biased self-report vs the other groups? Also note that both low-carb groups had similar "other" instructions re red meat/cholesterol etc. So, unless it was the tea and/or duckweed that causatively led to reduction in intake of X, Y Z...
Any information on powdered Wolffia vs fresh? I the powder effective?
I’d guess it’s similar
What's the 411 on Green Tea Extract supplementation? Keep up the great content!
Awesome work Dr Nick
Thank you kindly
I wonder if green tea used as kombucha would produce the same ingredients?
Very interesting and very well done.. Drink green tea all the time but now where do we get our space veggies?
Call Elon… ;)
Always interesting. Thanks Dr Nick.
Glad you enjoyed it!
@nicknorwitzPhD Nick, how do we separate out "combined with sensible diet and exercise" from the results and know the true effect of the tested theory, in this or any test involving weight loss???
Very interesting for moust of the people, but are there any other sources for us, that are sensitive to oxalates and histamin?
Cutting dairy and running sprints helps massively too. 💪🏼
I could never give up cheese... esp Roquefort
I can give it up temporarily. But I’ll be returning to it and seeing how my body reacts. I love jarlsburg.
Very interesting! Hard to find just duckweed powder, though: I only seem to find it as a minor component of “green” health powders :-/
More on the magic of microbiome-produced metabolites, please!
So interesting with the "Mediterranean diet", which I'd associate with loads of bread, pizza, pasta, potatoes, albeit freshly produced, served and enjoyed with much love, cheese and delicious sauce
Med diet is more about loads of olive oil, sardines, fish, pork, beef, etc. They will serve on the side bread and potatoes. Pizza and pasta came later in history and aren't eaten very often by the long-lived natives of the area.
Thank you for the awesome video Dr Norowitz! I have an upcoming Dexa scan in Cambridge to establish some baselines. If we were interested in adding Wolffia Globosa to our diets, where might we find it? I've only seen Wolffia Globosa supplement powders on Amazon and I can't imagine that would have the same impact? Thank you again!
Nick
thank you for providing this type of content! I have had a DNA test by 10x health and one of the results is double bad COMT gene, with recommendation to avoid green tea because it said it may worsen COMT symptoms. I am 64 and just a bit overweight, several years ago I changed my diet and lost 50 lbs and have kept it off however I am stuck at new body weight point with more weight to lose. I'm looking for a strategy to reduce visceral fat. Please comment
What kind of green tea do you use, sir?
Sample size?
Environmental/ life style controls?
Other relevant variables not controlled for?
n = 286. 90% retention at 18 months. Starting BMI 31.2 in all groups. All baseline characteristic re in Table 1. Quite similar. Feel free to look. It was a free living RCT, given the duration of the study. The assumption is one does not need to "control" for things like step count since the randomized should eliminate that as a confounder.
Can’t get this in supplement form?
Does black tea lose anything during the oxidation process to make it any less beneficial in this respect than green tea?
Based on my searchers, Green Tea > Black
The conclusion of the study adds in reduction in red/processed meat as well as the variables you mentioned. Did the study tease out processed vs not process red meat? I do not understand lumping those things together, apples and oranges as my Algebra teacher used to say.
No it didn’t. I also don’t necessarily agree with that conclusion based on the presented data. It also wasn’t a between group difference, more of a background factor common across groups.
Why not compared with Carnivore Diet?
Because I didn’t design the study
Green tea contains caffeine. 4 cups would equate to 200 mg caffeine. Caffeine makes people move more and have higher heart rates. Were calories equated for the extra calories burned whith this? They should do a rhcc with a group with plain caffeine as well
What would you suggest for people with IBS who are sensitive to caffeine and nuts …and really need to lose visceral fat?😢
Well, I’m in that camp. I think a very low carb diet with or without fasting likely is even more potent than the green med diet described. That’s speculation. I don’t have head to head tests. Works for me. Also decaf green tea should have a similar effect
@ Thank you 😊
There was also a study on avocados , an avocado a day keeps the belly fat away
Pomegranates are also high in ellangitanins. One of the highest I think. Not super low carb though.
See video notes. They are mentioned.
Quite interesting article. Too bad they chose to add something that is not available over here.
Wolffia globosa is a cute, tiny plant; I have some growing in a bowl of water. I plan to taste it at some point...
why in the world would a study put in 2 variables and not just 1 at a time? We have no way to know which variable caused the results, how do we know if 2 variables together had a synergistic effect or not.
I aim for 3 coffees daily (one has added mushroom powder, and can be decaff if evening) and 3 Green Tea (one as matcha and evening is decaff version)
The wolfia plant is one of the common plants fish hobbyists and fish breeders feed to their fish in southeast Asia. I used to keep wolfia to feed my goldfish. They are so easy to grow.
You need a podcast so I can learn how to be healthy at work all day
Your videos are always interesting, thank you for this shared work. We must also consider hormones, if we are a woman or a man and hormonal age I think. When I was younger I ate a lot and I didn't gain too much weight. now it's hard. I am very very sporty (>12h/week of fight’s sports) and >50 years old. I eat very well. No classic diet I follow to lose ten extra pounds. and I know nutrition well. I tried the ketogenic diet, the Mediterranean diet and the carnivore diet. The low calorie strict carnivore is what works best for me. When I'm not on a diet, I naturally eat a lot of organic peanut butter, nuts from my garden, cheese aged in raw milk (I live in France), and a lot of meat, and have been doing so for years. Espresso coffee and green tea every day. This diet suits me perfectly for my health, to perform in my combat sports, but unfortunately not to lose weight. Even when I do intense sports weekends like 8 hours a day, I don't lose a single gram. On the other hand, I'm gaining muscle and getting leaner, I'm losing water I think, which helps a little.
The ONLY method that works for me, a postmenopausal woman, is when I stick to a VERY low-calorie diet, taking into account that I also do two hours of sport every day. To lose weight I must be hungry and limit myself to 1200kcal per day. I believe that genetics determines a lot. being able to store is good for survival, but not for our aesthetic desires.
The best proven method that makes me lose weight is a very hypocaloric carnivore diet (very important because Dr Dagostino says that carnivore not associated with hypocaloric diet makes you age, be careful), a low-carb diet (just enough to practice my sports, i.e. the equivalent of two large fruits per day) you also need omega 3 (a tablespoon of canned cod liver and its oil), practice intermittent fasting (I don't eat before 12am), miso broth, fish, beef, fatty veal, fish fillets, very few green vegetables (I can't digest them anymore unfortunately), two kiwis, or a grapefruit, a little kefir . And no nuts. even macadamia. Every time I return to the usual diet with lots of nuts, even when controlling calorie intake, I gain weight or I don't lose, but on the other hand I feel super fit on a daily basis and for sport. Health diet and weight loss diet are two different things.
