The Cost of Losing 20 Pounds
On the Medifast plan, you will eat five small Medifast meals per day, and one homemade "lean and green" meal, consisting of a lean meat and veggies. The Medifast meals tend to be soft foods, like shakes, puddings, and soups, but their bars are also popular. You will lose weight faster on the Midfast diet than other weight loss systems, but this may make it harder for some to maintain their weight loss without Medifast products. Expect to lose two to five pounds per week.
Cost of Losing 20 Pounds: $300 to $750, depending on the speed of your weight loss, plus grocery costs for your “lean and green” meals
Cost per Pound: $15 to $38 (not including groceries)
MoneyWatch Conclusion: "Choose this more extreme plan only if quick weight loss is your priority."
