How to lose wight!?

Eat fewer calories: Our bodies are in a simple state of balance. If we eat more calories than we use, we gain weight. If we eat fewer calories than we use, we lose weight. So, people who want to lose weight must eat less than they use on most days, but occasionally may eat more than they use on other days... but it averages out over time, so that they are eating fewer calories overall, than they use each day.
