Thread: Long time fitness person here.. and I'm still confused about this "fat loss" question

I should know the answer to this but I hear too much conflicting info. Can somebody help me understand this? I'll try to simplify it.


If you're using intermittent fasting as a method of weight loss (calorie reduction), which one of these methods would have you lose weight fastest/best?


Option A: The person only eats one meal a day, a dinner (assuming there'd be a deficit here)


Option B: The person does the same except they have a protein shake (something as clean as protein mixed with water) in the middle of the day.



I would normally assume A because the daily caloric intake would be less overall, but, I see conflicting sources, some saying that option A would put your body in a moderate "starvation" mode, meaning you hang onto those calories more, and therefore option B is more effective.


Does anybody with a real education in this know the answer?
