Recent studies show that using nutritional supplements can maximize workouts, allowing exercisers to run the 40-yard dash in only 20 yards. Garner your fitness efforts with today's Groupon: for $59, you get a four-week weight-loss program with four B12 injections at Physicians Weight Loss Centers in Columbia (a $398 value).

Patients with health risks or who are on prescription medication must present a physician-approved medical-release form to receive injections.

The licensed nutritionists and doctors at Physicians Weight Loss Centers help clients banish excess poundage through month-long weight-loss programs designed to unburden people of up to six pounds each week. An initial consultation with one of the center's counselors assesses clients' specific health goals and dietary tastes, helping determine which of six base programs, designed by nutritionists, will best benefit them. The medical staff of the center builds on the base programs with food combinations customized to each guest and prescribes supplements and regular oil changes to keep the body running at peak performance. Though prepared meals may be substituted at the request of the client (not included in this Groupon), the tailor-made menus are populated with food easily found at the grocery store. Trained to work with a range of backgrounds, the center's medical professionals can tailor programs to special nutritional demands, such as vegetarianism, cultural dietary limits, a distrust of Count Chocula, or restrictions from prescription medications.

Clients of Physicians Weight Loss Centers' inch-shedding program also receive weekly B12 injections. These 10-minute treatments boost energy levels for up to a week, eliminating the need for caffeine or siphoning sprightliness from a humming bird.
