Its hard to stick to a diet. You have so much to deal with. Hunger and cravings, not to mention the expense, all come to mind when you think of the word diet. But the truth is, all that expensive diet food is really harming you. Its usually over-processed to the point that your body probably doesnt even recognize that it is food. It cannot digest it, and you have stomach issues, heartburn, and vacillate between constipation and diarrhea.
