Sugar in chocolate milk is rocket fuel
A proper post-workout drink is more than proteins. You need carbohydrates as well, meaning sugar.
Professional athletes that practice high endurance sports like long-distance running, cycling or swimming need to replenish their energy. That’s why sports drinks like Gatorade are packed with sugar.
We should mention sugars in chocolate and milk are better than the high-fructose syrup that sweetens sports drinks; your body digests them better and at a slower pace.
Having a sweet treat after a workout is not uncommon, being energy bars a regular alternative, but if you can have that sugar in your drink, even better.
