Questions
Can I replace all my meals with ready-to-drink shakes?
Most programs use them for one or two meals a day alongside real food. Full replacement for long periods should be medically supervised.
Why does my shake leave me hungry?
It is probably a snack-calorie protein shake being used as a meal. Pair it with fiber-rich food or choose a complete meal-replacement bottle.
