overweight, of COURSE it can! That's why it's called an MRP - Meal Replacement Powder. Now, that doesn't mean 6, balanced, 3/60's a day, and you're on your way, but it does mean it is desigend to be a perfect meal. You can use it to supplement your calories, replace some calories, add calories. All MRP's are versatile, 3/60 just happens to taste best.
