I'm not sure what you think this study says... Yes, in the abstract the study draws the conclusion that meal frequency doesn't affect fat loss, but if you read the treatment protocol in the study, you find this: One meal/d comprising 75-80% of energy intake was served at 12.45-13.45 hours. The remaining 20-25% of intake was distributed throughout the day to allow drinks of fruit juice or milk for tea and coffee. We can't call it IF when, although the person is only having one meal a day, they are spending the rest of the day drinking 25 percent of that day's calories as fruit juice. The causal theory for why IF works is that extended periods of fasting lead to low levels of insulin and high(er) of cortisol - thereby increasing fat burning significantly. This desired hormone response would be very significantly counter-acted by 200-300 calories of fruit juice throughout the day.
