Frequently Asked Questions
How many calories does a boxer need per day?
Most boxers in active training need 2,800–4,000 calories per day depending on body weight, training volume, and phase. A 70 kg boxer training twice daily may need up to 3,500 kcal, while a lighter boxer on single sessions may maintain on 2,400–2,800 kcal. Use your TDEE as the baseline and adjust based on weight trends.
What macros do boxers need?
A practical starting point for boxers in full training is 5–7 g of carbohydrate per kg of body weight, 1.8–2.2 g of protein per kg, and fat making up the remaining 20–30% of calories. During fight week, carbs drop to 1–3 g/kg to reduce body mass without losing energy reserves.
How do boxers cut weight safely?
Safe weight cutting limits rapid loss to no more than 5% of body mass. The process involves gradually reducing carbohydrate and sodium intake in the days leading up to the weigh-in rather than using extreme dehydration. Rehydration and carbohydrate loading in the hours between weigh-in and competition are equally important for performance.
What should a boxer eat before a fight?
Two to four hours before competing, eat a carbohydrate-rich, moderate-protein meal that is low in fat and fiber — such as white rice with grilled chicken and a banana. Avoid high-fat or high-fiber foods that slow digestion and can cause GI discomfort during rounds. Post-weigh-in, prioritize fluid and carbohydrate reloading at up to 60 g of carbs per hour.
How much protein does a boxer need?
Boxers need 1.8–2.2 g of protein per kg of body weight daily during general training, rising to 2.2–2.7 g/kg during weight-cutting phases when the risk of muscle loss increases. For a 70 kg boxer, that is roughly 126–189 g of protein per day depending on the training phase.
