- Do meal replacement powders and shakes help? Meal replacement shakes -- ready-to-drink or made from a powder, have been shown to help people on diets lose more weight, improve blood sugar control for people with type 2 diabetes, and boost protein intake to increase muscle mass. It can also offer a more healthful alternative to snack foods when you are unable to have a regular meal. In particular, meal replacements offer protein in a convenient form, along with carbohydrates (and often fiber) as well as fats. The products, however, are not meant to replace all of your meals and consumption of whole foods, such as fruits and vegetables. (See "What It Does").
- What's in meal replacement shakes? Most products provide about 10 to 20 grams of protein (from a variety of sources) per serving but vary widely in the amounts and types of carbohydrates and fats they include. They may also have a range of vitamins, minerals, and botanical ingredients. Serving sizes also range widely, from about 25 to 60 grams providing about 90 to 400 Calories. (See "Comparison Chart").
