OPTAVIA Diet

Optavia Diet is owned by Medifast, a company that provides ready-to-eat meals. Both the Master Diet (aka Medifast) and Optavia are low-calorie diets that combine packaged and homemade foods to promote weight loss. Optavia products have the same nutritional diversity as the original Medifast products, but without artificial colors, flavors or sweeteners.

The Optavia Diet consists of three weight loss plans namely 'Optimal Weight 5 & 1', 'Optimal Weight 4 & 2 & 1' and a weight maintenance plan of 'Optimal Weight 3 & 3'. Studies done for the Medifast program also apply to OPTAVIA because the nutritional profiles of the two programs are identical. With limited dietary options, sticking to this plan will almost certainly help with weight loss. According to the company, the average weight loss on the '5&1 Plan' is 12 pounds over 12 weeks. The average weight loss for 'Plan 4 & 2 & 1' is 10 pounds in 12 weeks. In addition to its ability to aid in weight loss, this diet may also lower blood sugar in people with diabetes. This diet can be difficult for believers. Currently, there are no studies examining the long-term results of the Optavia diet. However, a similar MediFast program study found that only 25% of participants maintained the diet for a year.
