Re: LOSING BODYFAT(Namgawd/Others)

[Guest guest]

I searched the archives for information on fat loss and came across

this message by Namgawd:

http://health.groups.yahoo.com/group/Supertraining/message/31

This is the first time I've heard that " the fatter you are the higher

your metabolism " . Is there any truth to this? I'm not sure if Namgawd [Dan

Wagman] is still a member here, but I'd be interested in replies by anyone.

Thanks,

***Increase in fat mass usually leads to an increase in body mass.

The body adapts to the mass i.e., the support structures compensate

e.g., the lean muscle mass increases. Obese individuals usually have

large calf muscles?

Greetings, from a 1988 USAFA grad.

To Nea Tripley and others interested in this topic:

Check out the study at this link:

http://www.unm.edu/~lkravitz/Article%20folder/resistwtman.html to show how

increased fat-free mass (lean muscle) increases RMR. However, note that the

increase is very slight (5 -6%). Also note that this study is done on young

adult males. (Why or why can't these researchers test a variety of subjects as

far as age, weight, gender, etc.??) I've seen other studies that show that one

pound of lean muscle mass increases RMR by a mere 5-15 calories or so.

Another study, which supports the original post asking why obese people have a

relatively higher RMR, can be found at:

http://216.239.57.104/search?q=cache:bZQZLQyPCBgJ:www.sportsci.org/encyc/drafts/\

Metabolic_rate.doc+increased+rmr+in+obese+due+to+overfeeding & hl=en

This increase in RMR may be linked to overfeeding and the Thermic Effect of Food

(TEF). The study also supports an increased RMR in endurance atheletes. Based

on my research, however, it's tough to back claims that aerobic exercise

increaess RMR. Instead, it seems that such exercise increases calories burned

both during exercise and afterwards, due to the Thermic Effect of Activity (TEA)

Therefore, do these endurance athletes actually gain more muscle mass to explain

their increased RMR, or is it their consistent feeding patterns that increase

it? Or perhaps endurance training actually does increase RMR.

Peggy,

Are you sure these individuals are adhering to proper calorie restrictions?

If you measure their daily calorie intake and find it to be around 2000

kcal/day (likely), and put them on a 1500 kcal/day diet, then their weight

really should start going down. I'm no pro, but for what it's worth, I've

never heard of a case where it hasn't. If it doesn't work, their immediate

metabolic downregulation of 500 kcal must be noticable in their energy

expenditure, i.e. look for symptoms such as cold limbs, tiredness, less

activity and such. (If no such things can be found, and their

bodyfat/weight stays the same, then they are cheating with their diets.)

Personally, I would be very surprised if they did not respond to the 500

kcal restriction by losing weight. If they do not, then there might be some

rare pathological condition in play, and they may want to seek an

endocrinologist.

's response may or may not be adequate for your particular group, but

for the general population, " nibbling " diets seems not to have any

significant advantage over " gorging " diets. (Seek Medline/PubMed on those

keywords for more info.) If a bodybuilder-style routine is adhered to,

engaging all body parts, with high protein intake and 500 kcal below

maintenance (which is a moving target, but not by that much) food intake,

with no excessive aerobics, then success for the obese subject is virtually

guaranteed. It may be a good idea to cycle the calorie restrictions, btw,

to recoup any lost lbm.
