A person should eat as often as necessary to stay energized according to the demands of the individual's daily schedule and activity levels, notes WebMD. There is no scientific proof that eating three large meals a day or several smaller meals a day is better for the metabolism.
The overall goal of a person's eating schedule should be to consume enough calories to maintain a healthy body weight, according to WebMD. When people attempt to eat several small meals throughout the day, they run the risk of overeating at each meal, and this may cause weight gain in the long run. It is also more difficult to choose healthy options when meal counts are increased. With this model, people may reach for junk food and compromise their health as a result. However, if a person is successfully able to divide his normal daily caloric budget into smaller healthy meals, there is nothing wrong with this method. This may suit some people who feel their appetites grow too strong when they try to wait between the standard schedule of breakfast, lunch and dinner.
Many doctors and nutritionists are in agreement that eating a balanced breakfast every morning is an effective way to lose weight, explains WebMD. This is especially true for people who tend to skip breakfast and let their appetites build to an uncontrollable level by the time lunch and dinner arrive. Eating breakfast helps people to avoid overeating later in the day.
