For most boxers, moderate calorie deficits work best because they allow fat loss while maintaining speed, power, recovery and conditioning. Aggressive calorie restriction may negatively affect performance, recovery capacity, and training quality.
Lean muscle gain phases should remain controlled. A moderate 300 calorie surplus is often ideal for supporting strength, recovery and muscle development without excessive weight gain that could reduce boxing performance.
