    I lost 40 pounds of body fat by counting calories to limit my caloric intake and doing a bit of exercise every day (cycling to work). The key really was counting calories. In our society food is readily available and we need to learn to limit the amount of calories we consume. It's crazy how easy it is to mis-calculate calories and therefore put on weight. The most important thing I learnt was that feeling hungry doesn't mean you are not getting enough calories, it just means, potentially, that what you've eaten is not satiating enough.

    This is a topic Im very interested in. Living in America we have an even worse problem with eating disorders. I believe its about 66% of Americans are either overweight or obese. I used to think as a child that those who were overweight and obese simply didnt exercise enough and I thought they were lazy with little self control. As Ive gotten older Ive come to realize the factors that can contribute to an individual being overweight. Im glad you have mentioned things like depression as a contributing factor. Its very sad how people can become overweight and obese and I wish there were easy options for them to become a normal weight. Sadly a percentage have to turn to risky surgeries like you mentioned or risk never losing the weight. Thanks for the video

      I think this is why it is reasonable to describe obesity as a disease, there are so many factors, that patient may not even be aware of
      With health and personalised interventions, people are able to overcome obesity, but it is a very difficult journey
      I can’t stress it enough, there is not a one size fits all approach, and that has been the issue with current approaches

    Good evening Dr. Gill, thank you for this video. I was disappointed that the category of being 'underweight' and it's associated health risks was omitted from this video. As someone with a BMI currently below 15.5 I feel that the health risks of being underweight are largely omitted from popular societal discourse. This omission and the narrative that there's no such thing as 'too thin' within parts of society (not this video specifically of course) reflect how difficult it is to communicate the severity of risk associated with being underweight, especially in terms of heart, bone, hormonal and reproductive health. By focusing the narrative on the negative health outcomes associated with the higher end of the weight spectrum it can be difficult for people who are underweight to fully understand or believe the severity of risk associated with being even only slightly (let alone severely) underweight which can hinder their ability/willingness to seek or accept medical help. Now I understand this video was intended for a broad audience to whom the obesity messaging is more applicable and in general stands to do more good. I'm used to putting my personal feelings aside in order to support what will help the 'greater good', however I must say it stung to see this video ignore the issue of being underweight. I admire your videos and was really hoping you'd cover this topic with the balanced and nuanced approach which you usually employ. You say in the video that "when something becomes normal it's hard to see that it's a problem" and I would say that in addition "when it's not spoken about its hard to see that it's a problem" too. Thank you again for the videos and I hope you take my comment on the constructive spirit in which it was intended.

    • @DrJamesGill
      @DrJamesGill  3 года назад +6

      I actually agree with you. It was an intentional choice. Only having so much time, to focus to the higher levels of BMI
      I have no intention of diminishing the issues associated with low BMI - I have personal connections to the topics, which I hope you appreciate I don’t think currently it’s something I’d be able to go into, but sufficient to say - I completely understand the risks and health issues with it
      It’s something that it would be good to address in future, but in a very sensitive manner, and with the focus on this video, I felt it could have been seen as a poor juxtaposition

      I once experienced this in a rather odd way.
      During a medical examination to revalidate my pilot's license I got an "approved" calification while being underweight (albeit with a little scolding from the examiner).
      My dad, who was also having the exam on the same day and place than me, got a "rejected" calification for being overweight. The curious thing is that his deviation from the healthy threshold was waaaaaaaaay smaller than mine, yet he got rejected and I got a pass. At the time I assumed it wasn't as linear a scale as it seemed (for eg, taking into consideration age, body fat, etc )
      But still, ever since I wondered if it was merely a matter of social construct or if there is actually a medical reason by which a mildly overweight person is more prone to suffering health issues than a moderately/severely underweight one...

    • @DrJamesGill
      @DrJamesGill  3 года назад +2

      There is certainly more evidence to support overweight having more health issues or risk of at least than mildly under weight.

    This is a wonderful insight into metabolic and weight problems. I'm strongly agree with the stigmatization that society has on weight issues and what some mental illnesses can lead, but it is also curious how some people within society tend to normalize and see with acceptance "being fat" after all the problems and bad outcomes that resulted from bullying. Now it is more common to hear parents saying to their kids to love as you are, your weight is ok (being overweight or obese) . As medical professionals we have to implement an educational consultation on our daily routine to patients and to not see this "normal". These issues still killing people worldwide.

    I've heard this many many many times. I've heard it too much. In fact, I'm gonna get angry at the next person who says this to me. I don't feel good after exercise. I feel like dying. I sleep 4 hours afterwards. I can't stand, focus. I feel light headed and I just don't feel good. I've never felt good. I got a personal trainer, so I know I'm doing it right... but I still don't enjoy anything about it. I dread it every single time. I dread the whole workout time, and what comes after it.

    Whilst I think BMI is certainly a good tool for many, I do think there is not nearly enough attention paid to body type. For example my body fat is low for a woman, my muscle mass is in the high range. My body type is definitely more muscular but I'm in no way an athlete or body builder. I work out for an hour 3 to 4 times a week and am very fit. I'm a size 10 on top and size 12 on my bottom (I'm naturally very hippy). And yet my BMI is 27, putting me well into the overweight range.

  • @aeward1982

    I find the bmi thing a bit odd. I'm about 10 stone and only 5ft 2 and apparently - overweight.
    I'm a size 10 on the bottom, size 8 on the top. As you can see from my profile picture, taken last summer, I'm not what anyone would look at and say that I needed to lose weight. I'm active, enjoy walking and biking, kayaking etc.. I have felt my middle is a little heavier in the last year, I'm a mum whose getting towards 40.
    I used to be able to eat whatever I liked and not put on weight and I recognise that isn't so much the case in the last 5 years or so.
    I feel for the nhs bmi index to call me overweight is a bit of an insult to be honest. I'm glad I'm not the sort to take it too much to heart as I know, for me, I'm an ok weight and I don't feel I look fat. I don't do diets.. I don't know why anyone would be so strict and make themselves miserable and guilt ridden, I just eat sensibly and get out and about.

    BMI is a load of rubbish imo, especially when I comes to polynesians.
    I have a flat stomach,large chest, 20inch calf muscles and tree trunk thighs but I am "morbidly obese". I would guess my body fat is near 12-15% but BMI indicates I would need to lose weight or that I ammat risk

    • @DrJamesGill
      @DrJamesGill  3 года назад +9

      You’ve made the point there. You know your body fat percentage. This is a MORE accurate assessment for risk calculation.
      That doesn’t mean that BMI is a bad estimator, it just means that we have to understand who we are calculating the risk for.
      BMI by that same measure is a better metric than simply weight alone.
      What matters when thinking about tools is HOW you use them, and in which situations it’s wrong to use them
      Let’s assume 1% of people rated obese, are actually body builders, sports people etc. BMI is an incorrect tool for them. HOWEVER by those people saying “This is rubbish IMO” it undermines the efforts to try and help the people that DO need to hear their BMI is putting them at risk
      “This fork is rubbish for eating my soup” means that the wrong tool is being use for the job, it doesn’t mean that the fork is rubbish

      Unless you have had it measured, I guarantee your body fat is higher than you think.
      Was a PT for a while and every single person who wanted it measured massively underestimated their body fat percentage.
      Also every polynesian I have known and trained was big but carried more bodyfat than average. Idk if it's the polynesian diet or genetics.

  • @neus8383
    @neus8383 3 года назад +2

    So we could say thay the % of body fat is a much better indicator of health that BMI but measuring it at home is a pain. Do you have any recommendations to measure it at home?

    • @DrJamesGill
      @DrJamesGill  3 года назад +1

      Absolutely. Body fat % is a far superior measure.
      Unfortunately getting an accurate measure at home is hard. There are plenty of body fat scales - Withings and Garmin are two good types
      My feeling there is the numerical value is likely erroneous, but the measurement will be accurate. So if you know you are over weight, and the scales say your body has is 15 red apples. The red apple but doesn’t matter, what matters that you work to lower the number.
      I hope that makes sense. I don’t have the statistical vocabulary here

    As much as I agree that being overweight is unhealthy, the actual values of BMI aren’t based on any actual scientific values - there is nothing that happens when you go from a BMI of 25 to 26 or from 20 to 19. It’s just a sliding scale and those are nice numbers.

      It’s not urgent, but the best way to think about it is the strain the body experiences.

It’s not actually HURTING, and not the end of the world to carry them around for a while, but you’ll probably wear out components in the car sooner over the years, and maybe increase the risk of extra wear and tear your car wouldn’t have normally received.

    I’m really happy to see that mentioned because I was the smallest of my siblings at birth and I was almost 9 Lbs. (4.082331 kg) so our bodies are somewhat built like solid muscular tree trunks which completely alter our BMI results because it fails to take bone/muscle mass in proportion to the amount of fat for our size/frame into account so I’ll always be seen as overweight according to my BMI even if health wise that’s not actually the case.
    That being said there was a time when I was overweight/obese and that’s because I didn’t know about the existence of the terms for asexuality, aromanticism, demigenders, and sensory and auditory processing disorders despite struggling with all of those so once I finally discovered them my mental health completely changed and my weight loss soon followed as a result.

      There are few absolutes. That said, if a patient is calculated as having a raised BMI, there are not many cases when it would be inaccurate in the general population
      If a patient was calculated as being obese, I would not hesitate to discuss with, and advise them of that fact and the serious health implications associated with being overweight
      I wouldn’t consider that calculation problematic or that any further investigation was needed with regard to their build unless a patient felt that they were a sportsperson or body builder - as that is an outlier case
