The best time to take a meal replacement shake will depend on your health goals and schedule. You can have a shake as a quick and nutritious breakfast on-the-go, a convenient healthy lunch when you are pushed for time and/or as a delicious protein-rich dinner that will fill you up without feeling heavy before bedtime. It can also be taken as a pre or post workout meal. To fuel a workout, research suggests consuming a meal combining protein and healthy carbs 30 minutes to a couple of hours prior. To aid muscle recovery and replenish glycogen (carbohydrate) stores after a workout, consuming a protein rich meal within an hour of a workout is recommended. When you want to schedule your meals and how much fuel or recovery you need will depend on the intensity and duration of exercise.
