Do realize that IF is just a meal timing protocol and doesn't hold any special benefits in regards to weight loss. A vast majority of those that utilize the IF protocol do so for the convenience, concentration and performance boost during fasted state, satiety (they prefer big meals) as well as other things that are not directly related to weight loss or body composition.
Meal timing and nutrient partitioning are largely a function of personal preference based on the individual's lifestyle, energy and satiety needs and so on.
