Upping Your Training? Make Sure You’re Getting Enough Of This

Reported by MindBodyGreen.

You've optimized your training schedule, stacked your recovery rituals, and still ended up sidelined. Before you blame your programming, look at your plate. A new systematic review and meta-analysis of nearly 6,000 adult distance runners found that dietary intake — specifically calories, fat, and fiber — was meaningfully linked to injury risk. And according to MindBodyGreen, the gap between injured and uninjured runners was smaller than you'd expect.

The numbers: injured female runners consumed roughly 300 to 450 fewer calories per day than their injury-free counterparts, and ate about 20 fewer grams of fat daily. Across genders, runners with lower fiber intake — just around 3 grams less per day — also faced elevated injury risk. We're not talking extreme restriction. We're talking the difference between a handful of almonds and skipping them.

What underfueling actually does to your body

When calories run low, your body makes choices you don't get a vote on. Muscle repair, bone remodeling, and reproductive hormone production are first on the chopping block — all critical for staying injury-resistant and hormonally healthy long-term. Fat compounds the issue: it's the backbone of sex hormone synthesis, it shuttles fat-soluble vitamins like D and K where they need to go, and it regulates the inflammation that accumulates with every hard workout. Cut it, and your bones, muscles, and connective tissue quietly suffer. Fiber's role is newer to the conversation, but the science is building — a robust gut microbiome appears to influence both injury prevention and recovery, which matters especially for endurance athletes whose bodies operate under chronic physical stress.

The practical fix doesn't require a sports dietitian on retainer. It requires intention. When your training volume goes up, your intake needs to rise with it. That means cooking your vegetables in olive oil instead of avoiding fat, adding avocado or nut butter to post-workout meals, building fiber in through lentils, beans, oats, and berries, and not treating a handful of trail mix like a dietary transgression. These are not dramatic interventions — they're the difference between a body that adapts to stress and one that breaks down under it.

The real takeaway here isn't that you need a new supplement stack or a macro spreadsheet. It's that chronic underfueling — often unintentional, often dressed up as "clean eating" — is one of the most underestimated risk factors in women's athletic health, and closing that gap by a few hundred calories or an extra tablespoon of olive oil may be all it takes to stay in the game.
