Basal and Total Metabolic Rate - Mifflin St. Jeor Equations
HTML-код
- Опубликовано: 17 сен 2024
- This video shows Dr. Evan Matthews providing an overview of how to calculate basal energy expenditure (similar to resting energy expenditure) and total energy expenditure estimates. Resting energy expenditure is calculated using the Mifflin St. Jeor equations in this video. Examples are shown for a man and a woman.
Physical Activity Factors
Sedentary (1.2) - desk job and little to no exercise
Light Activity (1.375) - light exercise/sports 1-3 days/week
Moderate Activity (1.55) - moderate exercise/sports 3-5 days/week
Very Active (1.725) - hard exercise/sports 6-7 days/week
Exceedingly Active (1.9) - hard daily exercise/sports and physical job or training
I have not found an original authoritative source for these standard activity factors for apparently healthy adults, but this is the source of the information above.

Additional textbook sources of these activity factors:
Source 1: Lutz C, Mazur E, Litch N. Nutrition and Diet Therapy. 6th ed. Philadelphia (PA): F.A. Davis; 2015. pg 523.
Source 2: American College of Sports Medicine. ACSM’s Resources for the Exercise Physiologist 3rd ed. (2022). Table 7.10
Source 2 cites source 1. Source 1 does not provide a citation. It appears as though these are research validated. Despite that they are commonly used and recommended by major organizations like the American College of Sports Medicine. Another source of activity factors that are lower than those in this video can be found at: www.cdc.gov/pc...

NASM has this calculation and recommends it for better accuracy. Thanks for the breakdown for math noob like me . Cheers 🥂
I'm happy it helped.
omg same lol i was so lost boots
I hope you have it figured out now.
@@VivoPhys thank you!
How do you know which one to use? Is the Mifflin St. Jeor better for overweight and obese people?
For example a for woman that is 40yrs old, 5'5ft tall and 170lbs. After calculating the BMI is 28.38kg/m2 which is considered overweight. which equation would you recommend using?
I was once taught that the Mifflin St. Jeor equation is better in overweight and obese subjects. I recently looked for a citation for this and did not find one on my quick search. However, I found this.

thank you for this video, very helpful :)
You are welcome.
thank you so helpful do you have worksheets for practice problems i am taking my RD exam soon and will like to have practice problems
Sorry. I do not.
@@VivoPhys ok 👌🏽 thanks again this very helpful
Thank you!
You're welcome!
so where would lifting weights 6 times a day for one hour? (Compound movements)/MMA
I think you made mistake in your calculations, it’s 1990.675
thanks for the video
Hi Chinenye Nnagbo. I checked my values again and found the same end results. Which value are you suggesting should be 1990.675? Thank you.
No one knows where these numbers came from?
I have not found an original resource yet. Each resource I have found does not provide a citation. Each has slightly different descriptions for the activity categories as well.
I found the following textbook sources of the physical activity factors listed in this video:

I actually asked chatGPT this and got the answer: They published their findings in a paper titled "A new predictive equation for resting energy expenditure in healthy individuals" in the American Journal of Clinical Nutrition in 1990.
It's a 7 page pdf that you can find online.
