Agreed with CatLady. I don't like diets very much because if you want to keep the weight off, you're going to need to change your lifestyle. You're going to stop going to certain restaurants. You're going to venture into new sections in the supermarket. You're going to start cooking different recipes.

As was mentioned before, the key to losing weight is watching your calorie intake. Calories = energy = what you need to live. Figure out your Basal Metabolic Rate (BMR) and work from there. If you live a VERY sedentive lifestyle, you take your weight, add a 0 to the end and add your original weight. For example, if you're 135 pounds: 1350+135= 1485 calories/day. This is only the bare requirement for living. However, your age and weight will be a factor, so I would suggest using the USDA's website's calculator as a *guideline*.

Keep in mind, 3500 calories = 1 pound of fat. That's a lot of calories to lose. However, if you're suggested to consume 2500 calories a day, you can cut back to 2000 calories (either by eating 2000 calories or by burning off 500 calories) each day. By the end of the week, you will have lost 1 pound (500 calories lost each day will = 3500). Sounds simple enough, right? The hard part is sticking with it. All I can say is, everything in moderation and EXERCISE EXERCISE EXERCISE!
