World is becoming heavier at a rate of 2. 5 pounds per decade. 3 out of 5 canadians are overweight, are obese. Obesity is due to overeating and a lack of exercise. Obesity is associated with cardiovascular disease, diabetes ii, some cancers, depression, reduced quality of life, arthritis, sleep disorders, higher chronic pain levels. Weight is often used to determine health status. A healthy weight is one that minimizes health risks. Body mass index (bmi)-weight in kg / height in m^2. Does not account for variations in musculature or bone mass. What is more important than bmi is having mostly lean body mass (muscle, bone, internal organs) and minimal levels of body fat. So, bmi must be used in combination with other tools in order to assess body composition. Body composition-relative proportions of fat and lean tissue that make up the body. Percent of fat relative to total body weight affects health risks.
