You may have seen meal replacement shakes on billboards, in magazines and down certain supermarket aisles, from low-calorie shakes to shakes that are aimed at helping you gain weight – without a knife and fork in sight. In fact, if they’re not already pre-made, they will tend to be sold in powder form, which simply needs mixing with milk or water.
These shakes come in various flavors, from chocolate through to vanilla, and even unflavored should you wish. They are filled with varying levels of calories, vitamins, minerals, and macronutrients, including protein, fats, and carbs. Some may be more fiber-filled than others, whilst some shakes have been specifically tailored to meet certain individual’s needs.
