From Physician's First Watch:
I only had a quick look but noted that it didn't seem to differentiate between loss of subcutaneous fat (relatively harmless) and loss of visceral fat (the harmful type).
The low-carb diet was better for insulin reduction - or was it? There seems to be a contradiction. On page 4 it says:
but on page 5 it says:
and on the first page it seems to argue against decreased insulin having some significance that is claimed for it.
I don't have time or brainpower to analyse it further but would be interested in what others make of it.
Cutting Dietary Fat Leads to Greater Body Fat Loss Than Cutting Carbs, Small Study Suggests

Patients may ask about a study suggesting that a reduced-fat diet leads to greater loss of body fat than a reduced-carbohydrate diet. The findings appear in Cell Metabolism.
Nineteen obese adults were admitted to the metabolic unit of the NIH Clinical Center for the study. Participants consumed an energy-balanced diet for 5 days, after which they were randomized to follow a reduced-fat or reduced-carbohydrate diet for 6 days. After a washout period, participants were readmitted and crossed over to the other diet. The two diets had similar caloric content, and participants maintained similar levels of activity.
Overall, the reduced fat diet was associated with significantly greater body fat loss than the reduced-carb diet (89 vs. 53 g/day of body fat). A mathematical model suggested, however, that differences in body fat loss between the diets would diminish over time.
The lead investigator noted in an NIH news release: "The real world is more complicated than a research lab ... it may be more important to consider which type of diet you'll be most likely to stick to over time."

The low-carb diet was better for insulin reduction - or was it? There seems to be a contradiction. On page 4 it says:
Both RC and RF diets appeared to significantly decrease plasma C-peptide, insulin...
but on page 5 it says:
only the carbohydrate-restricted diet led to decreased insulin secretion
and on the first page it seems to argue against decreased insulin having some significance that is claimed for it.
I don't have time or brainpower to analyse it further but would be interested in what others make of it.
