Losing weight comes down to a simple science of eating fewer calories than you burn. If you measure your calorie intake, as well as using reliable techniques and instruments to estimate your calorie-burn, you can be sure that you are on a fail-safe path to losing weight. While this may be difficult, it is a sure-fire way to slim down.
Eating at restaurants and getting takeout food can be expensive and result in eating more calories than you need to. If you are seriously trying to lose weight, you should eat most of your meals at home. You will save money, and also be able to accurately estimate your calorie intake, which is very important.
