419: How to Lose Weight in Season Without Hurting Performance

Endurance athletes face significant performance risks when attempting weight loss during the competitive season, making it essential to prioritize conservative strategies over rapid results. Aiming for a modest loss of 0.25 to 0.5 pounds per week prevents the body from entering a survival state, which otherwise suppresses metabolic rate and triggers muscle catabolism. Maintaining lean body mass requires a strategic approach, specifically increasing protein consumption to 1.4–1.8 grams per kilogram of body weight and implementing targeted strength training. Rather than chasing the body composition of elite professionals, athletes should focus on individual health markers, including mood, sleep quality, and reproductive health. Because caloric deficits inherently stress the body, fueling must be periodized around training loads to ensure adequate recovery and sustained performance, avoiding the pitfalls of diet culture and non-evidence-based interventions.
