Of course it's not going to work if you give in to your cravings. The diet is supposed to help you to STOP OVEREATING. One meal, one serving. No more HUGE meals with multiple servings. Smaller portions will help to shrink down the size of your stomach so you get full faster when it comes time to eat your regular meals.
You need to be DISCIPLINED in order to see results. You can't cheat and still expect the diet to work. If you're serious about losing weight, follow whatever diet plan you're trying, exercise and drink lots of water.
If you think this Special K challenge will work for you if you DON'T follow the guideline and not exercise, you're NOT going to lose weight.
