Company’s Scientists Find That Its Weight Loss Program Works Well

September 22, 2015: 12:00 AM EST
A study conducted by scientists at weight loss company Medifast found the 4 & 2 & 1 Plan used at Medifast Weight Control Centers was effective for weight loss after 12 weeks. The scientists looked at the records of 310 customers, finding that the average weight loss was 24 pounds. The plan was also effective at preserving lean muscle mass and improving cardiometabolic risk factors. Customers – men, women, and younger and older adults – who stuck with the plan for 24 weeks lost an average of 35 pounds. More than 75 percent of active 12-week customers lost at least five percent body weight and more than 85 percent of 24-week customers lost five percent or more.
