Fitness Nutrition and Meal Prep Guides
Different training styles have genuinely different nutrition priorities. These 18 guides start from what each modality actually demands, cite independent research separately from any organisation's own marketing, and show how macro-labelled meals from our 100% dedicated gluten-free kitchen fit into everyday eating around training. Gluten-free is not itself a performance strategy: it matters if you have coeliac disease or gluten sensitivity, and every meal lists its own macros so you can match food to your targets.

Hybrid & obstacle racing
- HYROX — Eight 1 km runs alternating with eight workout stations — fuelling for a hybrid race that never lets your heart rate settle.
- CrossFit — Constantly varied, high-intensity functional work — and an honest look at how thin the sport-specific nutrition evidence still is.
- Functional fitness — The non-branded starting point: how to eat when your week mixes lifting, carries, conditioning and whatever the coach writes.
- Spartan / OCR — A 5K Sprint and a 50K Ultra are not the same nutritional event — distance drives everything on this page.
- DEKA — Ten functional zones, each preceded by a 500m run — a 5K chopped into intervals you cannot pace evenly.
Strength & physique
- Strength training — Protein, enough total energy, and carbohydrate scaled to training volume — with the honest note that more protein is not endlessly better.
- Bodybuilding — Protein distribution, energy context and honest language about cutting — without the extremes.
- Powerlifting — Fuelling heavy training days and recovery — plus a clear line on why weight-class manipulation needs supervision.
Endurance
- Running — Easy runs, long runs, intervals and race day are four different nutrition problems — this guide separates them.
- Cycling — Long durations, a friendlier gut, and on-bike fuelling that prepared meals deliberately do not try to replace.
- Triathlon — Three disciplines, multi-session days, and a logistics problem that meal prep genuinely solves.
Studio & class formats
- Orangetheory — Treadmill, rower and floor work in one hour — practical before-and-after-class eating, without repeating the studio's marketing as science.
- F45 — 45-minute circuit-style team training — high frequency, tight timing, and a meal plan that has to survive a 5:15am alarm.
- Barry's — Treadmill intervals alternating with floor strength — and Double Floor days that change the emphasis entirely.
- BODYPUMP — High-rep, light-load strength endurance — related to lifting, but not the same nutritional animal as powerlifting.
- Bootcamp — Outdoor and gym bootcamps: mixed cardio and resistance on a fixed clock, with meal timing as the real constraint.
Low-to-moderate intensity
- Pilates — Light-to-moderate metabolic demand in the pooled evidence — so this guide deliberately does not read like marathon fuelling.
- Yoga — From restorative to hot vinyasa — timing, comfort and hydration matter more than macros, and no food detoxifies anything.
