Meal replacement is a concoction of synthetic vitamins, sugars, and starches masquerading as a meal. You're not nourishing your body, you're just filling it with artificial substitutes. This is not food, it's a chemical imitation.
Why trash
Science fiction food — synthetic nutrients suspended in seed oil and maltodextrin. Humans aren't machines.
Try instead
Eggs, bone broth, or full-fat coconut milk
