A calorie is a unit of energy. Restricting calories means eating fewer calories than your body needs. This can lead to weight loss.
Calorie restriction has been shown to have many health benefits. These include improved cardiovascular health, reduced risk of cancer and diabetes, and slowed aging. Calorie restriction may also increase lifespan.
There are different ways to restrict calories. One way is to eat fewer calories overall. Another way is to eat the same number of calories but spread them out over the day so that you’re never hungry.
If you’re thinking about trying calorie restriction, talk to your doctor first. They can help you figure out how many calories you need and whether this approach is right for you.
