Nutrient timing is a common topic in fitness, but the information can be confusing. Some people believe that exercising on an empty stomach burns more fat, but experts say there is little proof of this. Dietitian Abby Langer explains that skipping food before a workout does not greatly affect performance or calories burned. However, eating just before exercising, especially foods high in fat, protein, or fiber, may cause stomach discomfort. Langer suggests eating carbohydrates before a workout and giving your body time to digest. After exercising, eating a balanced meal helps muscles recover and restores energy. The idea that you must eat protein within an hour after working out, called the “anabolic window,” has also been questioned. According to expert Krista Austin, the body absorbs nutrients over a longer period, so there is no need to rush. Austin advises eating about 25 to 30 grams of protein with each meal to support recovery. For those doing long workouts, such as marathon training, eating carb-rich snacks can help maintain energy. Both experts agree that focusing on a healthy, balanced diet matters most.
