Nutrition for the Injured Athlete: What to Eat When You Can't Train
A complete guide to nutrition across the full injury arc — acute phase through return to play — including specific guidance for stress fractures, muscle strains, and concussion, with the evidence on why restricting food during injury delays healing.
Why this matters
The moment an athlete gets injured, one of the first things they think — and often the first thing well-meaning adults suggest — is that they should eat less.

Big idea
Healing raises nutrient demand
- Tissue repair costs energy even when training drops.
- Growth and normal adolescent needs do not pause.
Protein plan
Feed recovery across the whole day
- Aim for protein at breakfast, lunch, dinner, and snacks.
- Recovery works better with repeated doses than one giant dinner.
Micronutrients
Bone, collagen, and immune support still matter
- Calcium, vitamin D, iron, and vitamin C show up often in recovery plans.
- Food first works best unless bloodwork or the clinician says otherwise.
The Fundamental Principle: Injury Increases Metabolic Demand
Tissue repair is an active, energy-intensive biological process.
Tissue repair is an active, energy-intensive biological process. The body responding to injury — reducing inflammation, building new collagen, regenerating muscle fibers, remodeling bone — requires substantial resources. Calories, protein, vitamins, and minerals are not optional inputs to this process. They are the…
An injured athlete's caloric needs do not drop as much as training load suggests.
A runner who was training 50 miles per week and is now non-weight-bearing after a stress fracture is no longer burning the 600–800 calories from daily running. But their body is now burning energy on:
- Tissue repair and inflammatory response
- Maintaining muscle mass in the affected area (which requires active nutritional support)
- Normal growth (for adolescents)
Collagen and Vitamin C: The Tendon/Ligament Protocol
Per IOC 2023 emerging evidence on collagen and injury rehabilitation, consuming 15–25g of collagen or gelatin combined with 50mg of vitamin C, 30–60 minutes before physical…
The mechanism
vitamin C is a required cofactor for the enzymes that build collagen cross-links. When collagen synthesis is…
Important caveat
This protocol applies most clearly to tendon and ligament injuries. Muscle strains and bone injuries have different…
