If you are looking for a healthy, natural, and socially responsible meal replacement check out Huel (huel.com).
It’s a powder derived solely from plants that contains all the macro and micro nutrients the human body needs. Humans + fuel = Huel.
A lot of land and resources go into producing meat and dairy and whey, which is generally used for protein in most supplements, comes from milk. Using a plant based product avoids that burden on the environment. It tastes a bit like sweet oatmeal and is best mixed with cold water.
If you are looking to control calories using a meal replacement helps avoid situations where hidden sauces and ingredients mess up your energy balance. It’s also a good way to avoid your diet suffering if you’re pressed for time.
Your main diet should still be whole foods with varying sources of nutrients, vitamins, and minerals but Huel is a good tool to have in your fitness bag.
