Energy intake

Obesity involves both an increased risk of premature death from a variety of causes and increased morbidity from conditions such as diabetes, varicose veins and arthritis (section 6.2.2). On the other hand, people who are significantly underweight are also at increased risk of illness as a result of undernutrition (see Chapter 8). For people whose body weight is within the desirable range, energy intake should be adequate to maintain a reasonably constant body weight, with an adequate amount of exercise. Energy expenditure in physical activity and appropriate levels of energy intake are discussed in section 6.1.
