When you severely limit your calorie intake, your body starts to conserve fat stores. In other words, the exercise needed to burn 100 calories on a normal diet (1200 calories per day), takes very much more exercise to burn those same 100 calories when you reduce your calorie intake. If you do succeed in dropping some pounds by starving yourself, you will quickly replace the pounds plus 10-20% more when you stop. If you don't stop, you will move into anorexia, which is a health and life threatening condition. If you stop and start, stop and start, that's a yo yo syndrome and leads to heart problems.
All you need to do is pay attention to what you eat, bump up your physical activity just a bit, and avoid the high calorie, high fat treats whenever you can. Another secret to getting the most from increased physical activity is getting the proper amount of sleep. Sleep deprivation causes your body to crave calories to keep energy levels up. Once you start altering your body's normal function, it's so difficult to ever get it to feel or function right again.
