Document Summary
Consider a personal plan for managing body weight. Health risks : reduced life expectancy, unhealthy cholesterol, cardiovascular disease, diabetes, cancer, and skin problems. Distribution of body fat - important indicator of health waist circumference. A negative body image - dissatisfaction with the body in general or some part of the body in particular. Very low levels of body fat - a threat to wellness including reproductive, circulatory, and immune system disorders. Genes influence body size and shape, body fat distribution, and metabolic rate. Metabolism is influenced by heredity, behaviour, weight loss or gain, and exercise. Hormones play a role in the accumulation of body fat, particularly in women during puberty, pregnancy, and menopause. When existing fat cells are filled, the body makes more, thereby increasing its ability to store fat. Eating calorie-dense foods contribute to our overweight and obese society. Physical activity most adults are inactive throughout the day.
