There are several variations of the amount of calories a person should eat in a day. It all depends on several factors. A person’s gender and weight should be considered. Typically, men need more calories than women do. Their bodies are built differently. Second, someone whose weight is larger than another would at least need to start out with more calories than the smaller person.
However, there is a standard or average amount of calories people in general should be consuming each day. Many foods in the grocery store use this standard amount when basing the daily percentage of vitamins the person is getting by eating this product. Usually, 2,000 calories is what is needed for the average women to maintain her weight. Usually, 2,500 calories is what is needed for men.
