Re: Fat Loss in Primates

[Guest guest]

Rodney,

I reviewed my own weight-loss charts and pictures:

http://www.scientificpsychic.com/fitness/pictures.html

Since I started CR, I lost 17.6 pounds going from 167 to 149.4 pounds

in total weight. My lean body mass went from 136.4 to 130.5, and my

fat mass went from 30.6 to 18.9 pounds. So, for me:

Total weight loss = 10.5%

Fat free mass loss = 4.3%

Fat mass loss = 38.2%

I have managed to keep a lot of my muscle mass through weight-bearing

exercises while eating a relatively high protein Zone-like diet. Even

after 5 years of CR, I notice that the subcutaneous fat in my

abdominal area continues to diminish slowly giving me slightly better

muscle definition.

Hi Tony:

Thanks for those numbers. If I put together a table similar to the one I did in that previous post, but in this case using your data - another primate ;; ^ ))) - this is what it shows:

Weight Changes Broken out by Fat and Lean Mass

total fat lean-------- ------ ------ ------Starting: 167·0 30·6 136·4Ending: 149·4 18·9 130·5

%change: -38·2% -4·3%

Lbs lost: 17·6 11·7 5·9% lost*: 100% 66·5% 33·5%

* percentage of total weight lost that was fat or lean mass. E.G. fat loss of 11·7 pounds is 66·5% of 17·6 pounds.

So here is yet another example where the proportion that fat constitutes of total weight lost is, in very round numbers, 'sixty-something' percent.
