The key to losing fat is that you must burn more calories than what you eat each day. If you consume too many calories - more than what you burn away by physical activity on any given day - the excess fat is stored in your fat cells. It's important to educate yourself about the various sources of calories and the concept of portion control. Many people are overweight for simply one reason - they overeat!
You can actually eating nothing but the healthiest of food, however, if you eat too much, the excess will be stored as fat. Fat loss is not about starving yourself; it is about eating the right types of food, controlling your portion size and possessing an awareness of the total number of calories you ingest on a daily basis. Also, you don't need tot go to the other extreme and starve your body of the valuable minerals and vitamins your system need to function properly, including - circulation, digestive, elimination, etc.
