As you might heard about intermittent fasting is a new diet plan which isn't that popular as other diets, partly it's because of you can't sell anything from this kind of weight loss process. You may have made a book about it or vlogging on youtube, but you can't sell things like in the "Paleo" business.

But I quite frankly say that nothing will be such an effective fat burner as the intermittent fasting and It's because of simple math. If you cut your calories under your calorie requirements you will start to burn fat and muscle(unfortunately) but ultimately you will lose weight. It is that easy.

Yes, you will struggle by starving but this is part of the process.
