Shake Me is formulated to serve as a complete meal. Alongside its 20 g of plant protein, a full US serving provides carbohydrates, fats, 10 g fiber, and vitamins and minerals in a 310-calorie portion.
A protein powder mainly helps you add protein; its other nutrients and calories vary. Choosing a product just because it has a similar protein number does not make it an equivalent meal. Compare the full label and intended use.
In your Complete Meals plan, use Shake Me instead of the selected meal. You do not need to eat that same meal and then drink the shake as a supplement.
