The Look AHEAD study was one of the largest weight loss studies (a randomized control trial) ever undertaken:
They used liquid meal replacement in the intervention group, 2 meals/day replaced for 6 months, 1 meal thereafter, with replacement snack bars once a day. The study ran for about 12 years.
Participants potentially can choose from four meal replacements, including SlimFast (SlimFast Foods), Glucerna (Ross Laboratories), OPTIFAST (Novartis Nutrition) and HMR (HMR, Inc.). All products are provided free of charge.
What do you think? Are meal-replacement beverages a healthy way to achieve weight loss?
Here’s an example of one, SlimFast. Eight, 10-ounce bottles cost about $26:
