It's a common reflex to slash intake the moment training stops — "I'm not burning it off, so I shouldn't eat it." But tissue repair, inflammation management, and immune function all draw on energy and protein, and under-fuelling this period can genuinely slow healing and increase muscle loss during time off.
The better question isn't "how much less should I eat" — it's "what does this specific recovery process actually need right now."
What to prioritise
Protein — don't let it drop
Protein needs generally stay similar to — or even slightly above — normal training levels during injury, to help offset the muscle loss that naturally comes with reduced activity. Spreading protein evenly across the day still applies here.
Energy — match it to actual activity, not old habits
Total energy needs usually do drop somewhat with reduced training — but by an amount matched to the actual reduction in activity, not an emotional overcorrection. A rough downward adjustment paired with body composition and wellbeing check-ins is safer than a sudden hard cut. The goal is minimising fat gain during time off without compromising healing — not weight loss during an injury.
Omega-3s & colour — support the repair process
Oily fish, plenty of fruit and vegetables, and adequate overall nutrient intake support the inflammatory and repair processes involved in healing — this is a good window to double down on food quality rather than cutting corners.
Vitamin D & calcium — especially for bone or joint injuries
Worth checking levels via your GP if the injury involves bone, especially if it's a stress-related injury — this ties directly into the energy availability considerations covered in our companion resource.
The pattern worth watching for: injury as an excuse to restrict
- "I can't train, so I shouldn't eat" is a common but risky mindset — it can compound the problem by slowing tissue repair right when the body needs support most.
- Mental health matters here too. Losing training is genuinely hard for many active people, and using restriction to feel a sense of control is a recognisable pattern worth naming early rather than after it's taken hold.
- Return-to-training nutrition should be planned, not improvised — energy and carbohydrate needs rise again as load returns, and this is worth a proper conversation rather than guessing.
