What is carb loading?
Carb loading is a nutrition strategy endurance athletes use to increase the glycogen stored in their body above its usual amount, improving exercise performance. This typically involves eating more carbs than average and decreasing exercise for one to six days before an athletic event or competition. Carb loading is recommended for endurance events lasting longer than 90 minutes, such as marathons, triathlons, long-distance cycling, and other sports that rely heavily on aerobic systems. Foods with low glycemic indices, like vegetables, legumes, and whole wheat pasta, should be minimised to ease food volumes and lower fibre to prevent gut issues.
What is the main purpose of carb-loading?
The main purpose of carb-loading is to provide you with energy for improving your performance on race/game days. Carb loading is essential before a race to maximise endurance performance in those lasting more than one hour, particularly if you are an endurance athlete/triathlete such as a cyclist, swimmer, or marathon runner. Team sport athletes will also benefit from carb-loading the day before a game (GD-1), but otherwise, carb-loading may not be necessary for other athletes.
Why are carbohydrates important for athletes?
Carbohydrates are an essential component in the athlete’s diet as they are the primary energy source during physical activity. The intricate process by which carbohydrates are broken down into glucose and stored as glycogen in the muscles and liver is crucial for sustaining physical performance during exercise. Using glycogen as a fuel source is essential in powering the body during training and preventing fatigue. Carbohydrates should also be consumed after training to help muscles recover by replenishing glycogen stores. Conversely, consuming too many carbohydrates may have a negative effect on body composition and weight management. As a result, athletes must understand their carbohydrate needs and choose carbohydrate intake wisely to maximise energy, speed, stamina, concentration, recovery, and fluid balance to improve their athletic performance.
What are the carbohydrate recommendations for athletes to maximise performance?
Use Carbohydrates to Maximise Training Performance
Carbohydrates are the main energy source for high-intensity exercise performance. For weight management, your nutrition should be periodized to maximize carbohydrate availability for performance and take into account your body’s energy requirements when at rest. With this in mind, ensure that you sufficiently support your training with sufficient simple carbohydrates before, during (depending on duration & intensity), and after. Endurance exercise in the fasted state also promotes fat metabolism, so occasionally training with reduced carbohydrate availability is also recommended. Exercise intensity is associated with a simultaneous increase in the dependence of carbohydrates for energy, so naturally, when you’re resting or performing the low-intensity exercise, e.g., walking, the body wants to use its fat stores as fuel. So when performance is not critical, periods of rest and reduced intensity should be fuelled by foods with reduced carbohydrate and higher fat (primarily unsaturated fats) along with sufficient protein.
Carb Loading After Exercise
Carb intake for athletes after their exercise depends on the intensity of the work and the timing of the next work session. Maximizing glycogen resynthesis (replenishing muscle glycogen stores) is essential for athletes competing again within the next 24-72 hours. This is enhanced by consuming carbohydrates at a rate of 1-1.2g/kg body mass per hour for the first 3-4 hours after competition.
Carbohydrate Recommendations For Endurance Athletes Should Be Done wisely
Low-glycaemic index (GI) carbohydrates have long been better than high-GI carbs, especially for fat loss diets. A food’s GI is determined by its effect on the body’s blood sugar levels; the higher the GI reflects, the higher the blood sugar response. Although research suggests there to be no difference between calorie-controlled diets that solely contain low- or high-GI carbohydrates, it would still be recommended to prioritize low-GI carbohydrates for good health to keep blood sugar levels under control and also to improve satiety to prevent overeating. So, carbohydrates for athletes should be chosen very carefully. Opting for fibrous, nutrient-rich vegetables to accompany a high-quality protein source helps reduce feelings of hunger during meals, and only adding additional carbohydrates (potatoes or whole grains) depends on training requirements.
Risk Of Carb Loading
Carb loading is not good for every athlete. You must consult with your doctor before beginning a carb-loading diet. Carb loading is not the perfect diet. In addition, it may lead to some side effects, such as: Digestive Discomfort: The foods rich in fibre should be avoided when you are on carb loading diet. Foods like beans and broccoli can cause bloating and loose stools.
Recommended Carbohydrate Intake For Endurance Athletes
Carbohydrate recommendations for athletes during exercise depend on exercise duration and intensity. The body requires more carbohydrates for more prolonged (>1.5 hrs) and higher intensity (>60% VO2max or max HR) sessions, typically averaging 30-60 g/hr carbohydrates when exercising for 1.5-2hrs, and a minimum of 60 g/hr and possibly as much as 90 g/hr for >2.5hours. Athletes can obtain the required carbohydrate intake by consuming simple sugars that are low fat, low protein, and low fibre. It can be from solid foods (energy or cereal bars, soft bake bars, white bread with jam, jelly sweets, rice cakes, or soreen), carbohydrate chews, gels, or drinks. Athletes can often get bored or discouraged from taking the same carbohydrate source during very long exercise sessions because they get fed up with the taste, texture, or gastrointestinal discomfort from overuse. Therefore, athletes may adopt the mix and match strategy using different sources to obtain the required carbohydrate intake. Athletes are highly encouraged to train and practise the nutrition strategy for competition to reduce gastrointestinal difficulties.
Carbohydrates For Athletes: Athletes Guide
Carbohydrate is considered the primary fuel for physical performance. Carbohydrate recommendations for athletes depend on the exercise, training, and intensity of the activities performed by athletes. Depending on the duration and intensity of training, athletes should consume about 40-70% of the total calories as carbohydrates. Similarly, athletes on low-energy diets should consume >25% fat, and athletes with large energy diets should consume about 30% fat. Overall, with factoring in a 15-25% demand for protein in the diet, athletes should adopt a low fat (20-30% of intake) and higher carbohydrate intake when energy demands for training intensity and volume are increased. Talking about the athletes who have low-calorie intakes, they should consume iron, calcium, zinc, magnesium, and vitamin B12. Similarly, high-calorie intakes athletes should be naturally high in or fortified with B-group vitamins. Athletes who are doing regular high-intensity activities are recommended to consume carbohydrate-electrolyte drinks during exercise as this helps to support the metabolic, circulatory, and thermoregulatory functions. Elite athletes should prioritise their diets for high-quality foods ahead of any supplements. The use of carbohydrate supplements during prolonged training, i.e., carbohydrate-electrolyte drinks/gels and other ergogenic aids, complement their diet to maintain energy levels. Still, getting the essential eating habits right first and foremost will allow athletes to maximise their performance.

How to Avoid Sugar Cravings
When you’re craving something sweet, then here are some sensible options to satisfy your sweet tooth:
Swap Chocolate with 85% Dark Chocolate
A natural source of cocoa that contains important nutrients such as iron, manganese, and zinc, it’s also a source of antioxidants. Just a couple of squares is also sufficient as it can be quite bitter, so you’re less likely to demolish a whole bar which is always possible when it’s Dairy Milk! Learn About Milk Chocolate Nutrition Vs Cacao Nutrition.
Use Nuts & Berries Instead of Sweets & Confectionary
Heavily processed sugary treats of no nutritional value should be swapped for sweet-tasting, antioxidant-rich, low-calorie berries. Together with mixed nuts and Greek yogurt makes the perfect snack.
Milk and Eggs are Good Replacement for Crisps, Chips & Savoury
Indulging in foods like crisps, chips, and pretzels are high in salt, but swapping these for a pint of milk is a great alternative that contains protein and is a natural source of sodium and other electrolytes.
Swap Cereal With Eggs
Cereals can be very high in sugar, which can negatively influence what you eat the rest of the day. Research shows that having high protein foods for breakfast improves food choices, suppresses appetite, and curbs sugar cravings later in the day compared to a typical carbohydrate-based breakfast. Replace your bowl of empty calories with some nutritious, heart-healthy eggs to help you feel fuller for longer and control your late-night sweet tooth cravings.
Get a good night’s sleep
Sleep deprivation is a common cause of overeating by disrupting hormone levels that regulate appetite. You are much more likely to eat more, especially poor choice foods if you regularly go with 6 or less hours of sleep per night. Sleep is essential for your body to recover and function properly, so make sure that you’re getting 8 hours each night.
Daily Carbohydrate Recommendations For Athletes: Take Home Points
- Periodize your carbohydrates to support your training reduce intake at times of rest, and reduce activity to promote fat utilization.
- Focus on low-GI carbohydrates in the form of fibrous vegetables, fruit, whole grains, legumes & dairy.
- Try to choose a sensible alternative when craving something sweet, e.g., dark chocolate, nuts, berry fruits & dairy.
- Increase protein at breakfast instead of sugary cereals to prevent sweet tooth cravings later in the day.
- Go to bed earlier and get at least 8 hours of sleep each night.
