After working out, eating carbs and protein—about 3–5 grams of carbs and 1.2–1.5 grams of protein for every kilo you weigh—helps your body recover better.
If you eat protein and carbs right after working out, you might recover faster, feel less tired, and refill your energy stores better than if you wait more than 2 hours.
If you work out hard with weights or long cardio, eating the right nutrients right after helps you bounce back from tiredness more than if you do a quick or light workout.
Older people or those who don’t usually eat much protein might get more out of having a protein and carb snack right after working out, compared to younger or high-protein eaters.
If you eat enough protein during the day, it might not matter whether you drink your recovery shake right after a workout or wait a bit — you’ll still recover just as well.
