In addition to the positive reinforcement, a spirit of competition is a healthy way to "keep the fire burning" and shed those unwanted pounds. This competitiveness can push an individual to avoid unnecessary calories, walk an extra mile or stick to the dreaded morning calisthenics.

It is so easy when dieting and exercising alone to become lax. Eating an extra helping, skipping an exercise session or completely giving up on a program is not as difficult for a loner. When you commit to a partner or a group, there is usually a greater chance that you will succeed. Quitting or failing to adhere to the plan carries a degree of guilt or shame that the individual seeks to avoid. Fear of failure will help outweigh the desire to quit.

When participating with a partner or group in a planned regimen, dieting and exercise can become fun rather than a dreaded chore. Together you can plan dietary menus, exercise that provides fun as well as benefits, and set individual and group goals.
