but I eat almost everything, I get fat.. I'll try to get fit again this summer

I understand what you're going through, I've experienced the same.

Many years ago, I'd eat a large block of candy (300grams) each night, two large packets of potato chips straight after that and have takeout for breakfast & lunch. Upon looking In the mirror, I didn't recognize the person I once was. I grabbed everything, thew It In the waste basket, drove to the local supermarket and stocked my kitchen with fruit and vegetables. And that was around 10 years ago.

The moral Is, you must ready to make the change via your own volition and once that happens, you'd be so glad you did.
