Eat after you exercise Eat a meal that has both carbohydrates and protein in it within two hours of your workout if possible. Eating after you work out can help muscles recover and replace their glycogen stores. Think about having a snack if your meal is more than two hours away.
The final verdict? Exercising in a fasted state may burn some quick body fat, but it's not the best option for your body in the long-run. Eat a small snack or meal before and after your workout to ensure that you're properly fueled to perform your best in the gym and recover quickly when you get home.
If you are trying to build more muscle, if so, eating before your workout is good. If you are trying to lose fat then avoiding eating before a workout is best for you. If you are wanting to maintain a healthy weight and maintain shape, eat something small before your workout, but not a full meal.
Having a snack about 30 minutes before your workout will also give you an energy boost — especially if you're doing moderate or high-intensity exercise for longer than 90 minutes, Dr. Cordova Vallejos said. She recommended a protein bar or even just an energy gel packet because they are easy on the stomach.
You're depriving your muscles of the amino acids they need to rebuild and recover. You're not replenishing the stored glucose (glycogen) in your muscles which can lead to further muscle breakdown. You'll get hungry a few hours later and likely overeat at that later meal.
Ideally, a person should eat a meal rich in complex carbohydrates and protein around 2–3 hours before exercising. Waiting a few hours after eating allows the body enough time to digest the meal. Alternately, a person may prefer a smaller meal that is mostly made up of simple carbohydrates.
Those who exercised before breakfast burned twice the fat as the men who ate breakfast before they worked out. In one aspect, working out without fuel allows the body to better use what has been stored rather than what is currently in the bloodstream from the meal prior to exercise.
Schlichter points to a review of 46 studies published in the Scandinavian Journal of Medicine & Science in Sports, which found that eating before exercise was beneficial for performance for aerobic workouts lasting more than an hour—though fasting before shorter workouts wasn't found to be detrimental.
Overall, the experts agree: Exercising in the morning is the best time of day to work out for logistical, effective and health reasons. When it comes to weight loss, a 2023 study published in the journal Obesity found exercising between 7 a.m. and 9 a.m. could help.
That plan is called the 30-30-30 rule. It's a simple but catchy idea that encourages you to eat 30 grams of protein within 30 minutes of waking up and then get 30 minutes of low-intensity exercise. The 30-30-30 rule now has millions of followers on TikTok.
The short answer: Many experts suggest having protein after a workout to build muscle mass. But preworkout or postworkout protein may help. Strenuous exercise creates microtears in the muscles. After a workout, your body repairs the damage using amino acids from dietary protein.
General guidelines suggest exercising 1 to 2 hours after a small meal and 30 to 60 minutes after a snack to fuel your workout and prevent stomach problems. But the best time to exercise after eating varies based on exercise intensity, what you eat, and other factors.
Aerobic exercise includes any activity that raises your heart rate such as walking, dancing, running or swimming. This can also include doing housework, gardening and playing with your children. Other types of exercise such as strength training, Pilates and yoga can also help you lose belly fat.
The bottom line
Hydrating after workouts is essential for recovering from exercise. Plain water is a great choice to replace lost fluids after moderate exercise. But other options, such as milk or tart-cherry juice, may offer additional benefits after high-intensity workouts.

Fasting combined with physical activity did not affect the effects of training on muscle performance.
Is Working Out On an Empty Stomach Bad for You? According to Roper, fasted exercise is generally safe for most people, but it may lead to side effects. “Because blood glucose gets depleted during fasting cardio, you can experience some side effects including lightheadedness and dizziness,” she said.
Packed with carbohydrates, bananas serve as a primary fuel source for your muscles during exercise. The natural sugars they contain provide a quick energy boost, making them an ideal pre-workout snack.
Bananas with peanut butter and Greek yogurt with some fruit are good snack options to eat 30 minutes to one hour before a workout.
Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue. Furthermore, if you aren't eating right you won't have the energy to do the workouts that lead to muscle gain.
Within the first ten minutes your heart rate increases meaning there is an increased supply of blood to the brain, making you more alert, blocking pain signals and then the body will use different energy systems depending on the duration and intensity of the exercise.
