Let's look at the study referenced in the article: (
http://www.cell.com/cell-metabolism/...131(15)00350-2)
Highlights
•19 adults with obesity were confined to a metabolic ward for two 2-week periods
•Cutting carbohydrates increased net fat oxidation, but cutting fat by equal calories had no effect
•Cutting fat resulted in more body fat loss as measured by metabolic balance
•Mathematical model simulations predicted small long-term differences in body fat
Only 19 people! That's hardly a study. And the simulation predict SMALL long term differences.
