Healthy adult men need an average of 2500 calories a day and women need 2000 calories. With tools on the internet, you can calculate how many calories you need to eat less to reach your target weight. The bottom line is that your energy intake should be lower than your energy use. When you burn more calories than you consume, your body will switch to burning fat. By burning fat, your body will continue to function this way.
