You know, Martin actually said that the only people that intermittent fasting will not be suited for are those people who require really huge amounts of calories or who have low appetites.
As long as you eat 3500 calorie sin your 8 hour eating window, then yes, I'm sure it will work. There have been a lot of great success stories using his protocols. If you struggle to hit the macros, then think about adding in some calorie dense food (like cream in your protein shakes etc.
But calories still count. IF has many benefits promting fat loss (leptin impact), and increasing growth hormone. The main benefits are psychological, in that it provides a very simple method to eat the correct amount of food. Because the eating window is short, you fill up on good clean food, and dont have the space or feel the need for junk food..
It's definitely worth trying in my opinion. I wont turn back! Give it a try for a month, you've got nothing to lose. Just make sure you keep the calories high if you struggle to gain weight.
