The Optavia Diet
Optavia is a meal replacement plan designed to help people lose weight. To restrict calories, the diet incorporates “fuelings” (shakes and protein bars) into six small meals per day. While dieters don’t count calories, they limit certain foods to a few servings per day.
Experts have pointed out that Optavia is similar to Medifast, which can reduce weight and blood pressure according to studies. Along with being expensive, Optavia includes an extreme and sometimes unhealthy calorie restriction, says registered dietitian Grace Derocha.
