Why does weight loss have to be rapid? Those who loose weight fast seem to gain it back fast too.
Here's a tip: Believe it or not, you can eat healthy whole foods and still enjoy life! Yes, I have been doing it every day for years and I'm enjoying life just as much now as I did when I ate junk. If you exclude high calorie processed foods for a period of time (perhaps weeks or months) those foods will become less and less important to you. You will not crave them after a period of time if you stay away from them. And the foods you thought you wouldn't like begin to taste better. On the other hand, every time you eat the wrong foods (fast food) the good healthy foods will suffer by comparison.
