Nutrition for Athletes How to Eat for Muscle and Performance
Proper timing ensures that
- The paleo diet is based on the presumed eating patterns of ancient hunter-gatherers during the Paleolithic era.
- It is recommended that athletes consume 1.25 to 1.5 L of (non-alcoholic) fluid for every kilogram of body weight lost during exercise.
- This plan should consider the varying requirements during competitive periods, training, or off-season, each with its distinct characteristics [29].
- For people with glucose intolerance, diabetes, or hyperglycemia, during exercise, such prescriptions can be dangerous or even fatal [1,99,100,101,102].
- It is also important to consume regular fluid during prolonged exercise to avoid dehydration.
- For example, the ISSN advises strength athletes consume carbohydrates and protein or protein on its own up to 4 hours before and up to 2 hours after exercise.

In rare cases, athletes might consume excessive amounts of fluids that dilute the blood too much, causing a low blood concentration of sodium. This condition is called hyponatraemia, which can potentially lead to seizures, collapse, coma or even death if not treated appropriately. Dehydration can impair athletic performance and, in extreme cases, may lead to collapse and even death. During digestion, all carbohydrates are broken down into sugars (primarily glucose), which are the body’s primary energy source. The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds.
Essential Nutrients

The best strategy for these types of situations is to begin your training session completely hydrated — again, a nutritionist can determine how to achieve that. Even more importantly, an athlete should never rely on thirst as an indicator to drink more water — if you’re running and feel thirsty, you’re already dehydrated. Needless to say, athletes will need more water and electrolytes than the average person to ensure they’re hydrated during workouts and games. The range for how much of each micronutrient you need varies greatly from one to the next, and just like macronutrients, certain athletes may need more or less depending on what their specialty is. Micronutrients, aka vitamins and minerals, are vital to eyesight, brain function, oxygen delivery, and a healthy immune system.
Benefits include improved thinking or cognition for children 6 to 13 and reduced short-term feelings of anxiety for adults. Regular physical activity can help keep your thinking, learning, and judgment skills sharp as you age. It can also reduce your risk of depression and anxiety and help you sleep better. The basis of a good sports nutrition strategy is to determine which fuels best suit the energy systems required to achieve optimal performance.
What to eat before your workout
For people exercising for more than 4 hours, up to 90 grams of carbohydrate per hour is recommended. Aerobic exercise boosts your cardiovascular system and improves lung health, which may help with energy levels. And men who exercise regularly are less likely to have problems with erectile dysfunction than are men who don’t exercise. Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep. Just don’t exercise too close to bedtime, or you may be too energized to go to sleep.
Best for gaining muscle: Paleo diet
In addition, it has been shown that weakening of the cortisol response is greatest with the combined use of CHO and PRO versus taking only CHO or PRO in a sample of untrained young adult men [113]. Aim to have stretching and flexibility activities in a fitness plan. Being more flexible can make it easier for you to do many everyday activities. Core exercises help train the muscles to support the spine in the back. And they help to use the upper and lower body muscles more effectively.
Studies suggest that eating or drinking carbohydrates before exercise can help you do better during your workout. And the carbohydrates may allow you to work out for a longer time or at a higher intensity. If you don’t eat, you might feel slow-moving or lightheaded when you exercise.
Generally, a healthy diet consists of many fresh fruits and vegetables and limits processed foods. But ask your doctor or a dietitian for advice on making more specific dietary changes to improve your health. Following a healthy eating pattern, including nutrient-dense foods from all food groups in appropriate amounts, can significantly lower your risk of chronic diseases. Unlike refined grains in processed foods, whole grains offer dietary fiber, which keeps you fuller for longer and supports heart health.
The triad of pre-, intra-, and post-exercise nutrition assumes pivotal significance in nutrient timing strategies, tailoring nutrition to fuel physical exertion, maintain energy levels, and initiate the recovery process [209]. Nutrient timing strategies contribute to fatigue prevention, reduction in muscle damage, and enhancements in overall recovery, playing a pivotal role in an athlete’s holistic approach to physical well-being [211]. In addition, athletes, grappling with stress, performance anxiety, and emotional factors shaping their eating habits, benefit from psychological strategies as effective interventions [195,212].
Pain and Sleep
Dr. Theodore Shybut, a sports medicine expert at Baylor College of Medicine, notes on the college’s website that some athletes may require two- to three times more calories than the average person. Choosing whole grains and other fiber-rich carbohydrates as part of a daily diet generally promotes health. The ISSN suggests that athletes training intensely for 2–6 hours per day 5–6 days of the week may burn over 600–1200 calories per hour while exercising. Athletes doing intense training may benefit from ingesting more than two times the recommended daily amount (RDA) of protein in their diet. For example, an athlete weighing 150 kg who performs high volume intense training would look to consume roughly 1,200–1,500 g of carbohydrates.
Nutrition Fact Check: Amplifying Science-Based Nutrition Facts
Each meal includes a list of ingredients and detailed nutrition information, which may be useful for athletes who are keeping tabs on their macronutrient intake. Instead of omitting certain foods altogether, Noom encourages followers to eat nutrient-dense ingredients like fruits, veggies, whole grains, and lean proteins. In fact, the DASH diet encourages followers to eat foods high in calcium, such as low fat dairy, to promote bone health. Studies have shown the DASH diet may help increase bone density (10, 11). It is also important to consume regular fluid during prolonged exercise to avoid dehydration.
Eating for Exercise and Sports
So notice how you feel during your workout and how your overall performance is affected by what you eat. Let your experience guide you on which pre- and post-exercise eating habits work best for you. Think about keeping a journal to see how your body reacts to meals and snacks so that you can change your diet for your best performance. Taken together, the research presented in this Special Issue supports the previously emphasized role of integrating diet and PA on general health and well-being across the lifespan. We’ve also provided a snapshot of how to adapt these nutrition principles in the UK context, highlighting regional foods, local dietary habits, and relevant guidelines.
What to Eat and Avoid If You’re Trying to Build Muscle
Embarking on a fitness journey, whether it’s weight loss, muscle gain, increased endurance, or overall well-being, isn’t just about strapping on trainers and hitting the gym. Understanding the nuanced interplay between exercise and nutrition is key to achieving and sustaining your goals. This is where professional guidance from Personal Trainers and Gym Instructors can be invaluable. Embracing regional foods and adhering to dietary guidelines can play a crucial role in designing a balanced diet for fitness in the UK.

During workouts, dehydration can compromise performance, increase fatigue, and delay recovery. Aim to consume a recovery meal or snack within 45 minutes to 2 hours post-workout, when the body’s ability to replenish glycogen stores and initiate muscle repair is at its peak. Workouts, especially strength and resistance training, cause micro-tears in your muscle tissue. Proteins, or more specifically, the amino acids in proteins, are fundamental to repairing this muscle damage and facilitating growth.
What to eat after your workout
The factors influencing nutritional choices among athletes are as diverse as the sports themselves. Personal preferences, cultural backgrounds, and the accessibility of certain foods play significant roles in shaping an athlete’s diet [10]. Moreover, an athlete’s knowledge about nutrition, or lack thereof, can greatly influence their food choices. Additionally, the goals of the athlete, whether they are health-related or performance-oriented, also steer their nutritional choices.
