Programs that evaluate an individual's height, weight and body composition as a means of assessing overall health and fitness. Included are programs that calculate a person's Body Mass Index (BMI), a figure that is based on the weight (in kilograms) divided by the height (in metres) squared and interpreted using a table which shows value ranges for people who are underweight, have normal weight or are overweight; and those that look at the individual's body weight in terms of percentage of body fat, lean body mass (including organs, muscle and bone) and percentage of body water. Personalized recommendations for nutrition and exercise may also be provided for people with underdeveloped musculature or excessive body fat. These tests may be provided as components of nutrition assessment and prescription services or physical fitness assessment programs, but are often available as separate screenings.
Programs that maintain lists of dietitians and nutritionists, and link individuals with qualified practitioners who can help them develop healthy eating habits and change their diet, if necessary, to manage their weight, reduce their cholesterol levels, lower their blood pressure, deal with diabetes or prevent and/or treat other health concerns.
Programs that provide information concerning the basic principles of healthful eating, food handling, food preparation and shopping skills. Included is information about the basic food groups, vitamin and mineral requirements, the relationship of nutrition to the preservation of good health and the prevention of illness, and dietary choices such as vegetarianism.
Programs that utilize one or a variety of techniques including nutrition education, exercise, special diets, protein sparing fasting, behaviour modification, hypnosis, medication or surgery to help individuals who have a weight control problem gain or lose weight to achieve a more healthful body weight and develop a lifestyle that allows them to maintain that weight.
Mutual support groups whose members are individuals who have a problem with compulsive eating, who eat the wrong foods or are people who are overweight and are using the group to develop self-esteem and self-confidence, and accept themselves as they are. Also included are groups that are structured specifically for or accept people who have a diagnosed eating disorder. The groups meet in-person, by telephone or via the Internet; provide emotional support, information and resources for those who participate; offer weight loss or weight gain support only, no special diets; and may include faith-based and secular 12-step groups as well as non-12 step groups.
