Hi 'all, I'm not an expert so please forgive me if this is a dumb question for some reason. Here's Something that confuses me about fat loss. Let's say you have someone who is active to the point that (near) total glycogen depletion is a common occurence, has a overall calorie deficit, protein intake is enough for muscle building but not enough to bump into (much) gluconeogenesis, but fat intake is higher than the body's needs. If I didn't just divided by zero, what are the mechanisms that would cause fat loss in this scenario? I don't think it's ketosis cause I believe that works through making intermittented fasting easy and increasing fat needs, but what would do you guys say?

In your question you wrote "has an overall calorie deficit." Regardless of where the calories come from, if you are at a deficit you will lose weight. I don't get what you are saying about fat intake being higher than the bodies needs. If one is consuming large amounts of fat but still running a calorie deficit at the end of the day, the body will still use it's own fat stores as fuel. A calorie restricted ketogenic diet is pretty much the fastest and most efficient way to lose body fat. Ketosis doesn't just "work" by making IF'ing easy and "increasing fat needs." Ketosis means your body is primarily burning ketones (modified fats) for fuel. True, this does make IF easier because your body can use it's fat stores as fuel more readily. Ketogenic diets mean one's insulin levels will be very low, allowing fat to be readily mobilized as fuel. I don't know where you are getting the "fat needs" thing from.
