It doesn't work.
This crap about people losing a ton of weight in a short period of time, it's not healthy and it's not true. Plus all this stuff he says about women when they build muscle they add bulk is so not true! Bigger muscles are based mainly on genetics.
If you want to lose weight, eat food in as close to it's natural state as possible. Meaning, no processed foods. Cut out the sugars and refined carbs as much as you can. Exercise for 4-6 times a week.
If you want to lose weight fast, don't fall for the gimmicks.
Unless you are extremely overweight or obese, the most you are going to lose a day is 1-2 lbs a week.
It's healthier and the weight stays off longer that way. If you fall for the gimmicks and lose weight fast, I can assure you it's muscle or water, and once you go back to the way you ate before, you will gain all of it back and then some.
Sorry for the longwinded answer. :)
I suggest you don't follow it, it's a waste of time.
