Re: Eating too much will pack on the fat, regardless of how much protein you eat

Both diets are high carb by MY measure of diets.
Is this the same study?

Why didn't the higher fat dieters exercise?

This stinks to high heaven as a study. Maybe it just my mood or
last nights two glasses of wine but this doesn't convince me.
Zero energy today, no hang over though. Poor sleep and stress?
I'd need the full paper to pull this thing apart or accept it in any

Weight loss reduces energy expenditure, but the contribution of
different macronutrients to this change is unclear.

We tested the hypothesis that macronutrient composition
of the diet might affect the partitioning of energy expenditure
during weight loss.

A substudy of 99 participants from the Preventing Overweight
Using Novel Dietary Strategies (POUNDS LOST) trial had total energy
expenditure (TEE) measured by doubly labeled water, and
resting energy expenditure (REE) measured by indirect
calorimetry at baseline and repeated at 6 months in 89 participants.
Participants were randomly assigned to one of four diets
with either 15 or 25% protein and 20 or 40% fat.

TEE and REE were positively correlated with each other
and with fat-free mass and body fat, at baseline and 6 months.
The average weight loss of  8.1±0.65 kg (least-square mean±s.e.)
reduced TEE by 120±56 kcal per day and REE by 136±18 kcal per day.
A greater weight loss at 6 months was associated with a
greater decrease in TEE and REE.
Participants eating the high-fat diet (HF) lost
significantly more fat-free mass (1.52±0.55 kg)
than the low-fat (LF) diet group (P<0.05).
Participants eating the LF diet had significantly higher measures of
physical activity than the HF group.

A greater weight loss was associated with a larger
decrease in both TEE and REE. The LF diet was associated
with significant changes in fat-free body mass and energy expenditure
physical activity compared with the HF diet.International Journal of
advance online publication, 27 September 2011; doi:10.1038/ijo.

The study you provided was not the same data set which Gys posted, but
the author was the same.
The study you provided showed that the high fat dieters lost more
muscle/organ tissue than the low fat group and the low fat group moved
around more.
Not the first time this has been shown. Very low carb high fat diets
show more muscle/organ loss that low calorie higher carb diets.
