No ab machine can rid of your gut. Not by itself.
No supplement, even the illegal ones, can give you a fantastic body all by itself.
You will have to exercise. You will have to diet.
It's going to be tough. You;ll probably fall down a lot and your friends will laugh at the weird foods you eat.
Then, as long as you are dieting and exercising, you will start to look better and people will stop laughing. Now, maybe, a supplement can help. But not until you have done the hard yards with, you guessed it, diet and exercise.
BTW by exercise I mean you need to lift some weight (or do bodyweight exercise) and get in some aerobic/anaerobic fitness work as well.
Do this and watch the pounds come off you.
