According to the Mayo Clinic, consuming less calories than one expends is the most important factor in weight loss. A diet consisting of Lean Cuisines can work if the daily caloric intake is less than the daily expenditure.
The Mayo Clinic recommends diet plans that include the major food groups in addition to the caloric standards necessary to lose weight. Enjoyable foods are also recommended, as losing weight can be difficult when a diet is composed of monotonous foods, even if they are healthy. Physical activity is a vital component in weight management and offers more health benefits than just restricting caloric intake.
