Only advice I can give you is:
It takes a lot of fucking hard work to lose weight.
If a diet seems to good to be true, take it with a grain of salt. Water diets and what not get results quick, but they aren't long term results.
Cut down your calorie intake while eating healthier; exercise between commericals, dont give yourself a break where you're just doing nothing. 20 pushups might not seem like alot, but it adds up. Dont forget cardio, too, jogging is a great way to lose some lbs
just my

on how to lose weight; from personal experience.
