> on top of the fact that the obese are already carrying extra muscle mass

Huh...I follow Lyle, but I've read the exact opposite in Body by Science: in cross-sectional views of obese people (CT scans), their muscles are small, weak, and atrophied.

IIRC, Body by Science makes the assertion that their muscles are essentially starved, because the metabolic system/insulin insensitivity/etc. are shunting energy primarily into fat cells.

And, with strength training, you can turn the metabolic tide back into energy getting into/being used by the muscles.

Disclaimer: It's been awhile since I read the book, and I might mistakenly being integrating ideas I'd read elsewhere.

Hrm, no pictures (which IIRC are convincing), but here's an article:
