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 meals with published calories, protein, carbohydrate and fat can fit into everyday eating around training.

How these guides are written
Independent peer-reviewed research is labelled separately from official descriptions published by gyms, studios and race organisers. Menu examples use only published SmashMeals values, and uncertainty is stated rather than filled with assumptions.

Start with enough food for the work
The 2023 International Olympic Committee consensus on Relative Energy Deficiency in Sport says that prolonged low energy availability can affect health and performance in female and male athletes. It is an expert consensus, not a trial of SmashMeals or any prepared-meal service. A published correction followed in February 2024, and a later critical analysis challenges how confidently energy availability and causality can be measured. Read the consensus statement, its correction and the critique together. This is not a self-diagnosis tool.
- Put the next seven days of training, travel, meals and snacks on one schedule.
- Protect regular eating opportunities; longer or harder days may need more food, not just more protein.
- Use the menu's listed calories, protein, carbohydrate and fat as planning inputs, not proof that a meal meets your whole-day needs.
- If eating enough has become difficult, or health, weight, injury or performance changes concern you, talk with a sports dietitian or clinician.
What the current menu can and cannot tell you
- Each currently listed meal shows calories, protein, carbohydrate and fat.
- Sodium, saturated fat, fiber, serving weight, ingredients and allergen details are not established unless the specific item publishes them.
- A prepared meal is not automatically a medical diet, an in-session fuel, a hydration plan or a complete athlete nutrition plan.
Start with this week's menu, confirm the fields shown on the item you are considering, and use a qualified professional for individual targets.
What gluten-free does and does not do for athletes
SmashMeals cooks in a 100% dedicated gluten-free kitchen in Kingsport, Tennessee. For an athlete with coeliac disease or non-coeliac gluten sensitivity, that removes a real logistical problem. For everyone else, eating gluten-free does not by itself improve recovery, energy or performance.
A more useful starting point is ordinary consistency: enough total food, regular eating opportunities, carbohydrate available for demanding sessions, and protein distributed across the day. The current menu publishes calories, protein, carbohydrate and fat by item; use only the fields actually shown.
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.
Nutrition questions by format
More from SmashMeals
Nutrition needs vary with body size, training volume, goals, health conditions and competition demands. For individualised performance or medical nutrition, work with a qualified sports dietitian or clinician.
Editorially reviewed by SmashMeals for source accuracy in September 2026. This page is written from published research and official format documentation; it is not medical or individualised sports-nutrition advice, and no clinician reviewed it.
Frequently asked questions
- How much protein do athletes need?
- Protein needs are individual. Body size, total energy intake, training load, goals and clinical needs all matter, so a single target is not right for every athlete. Each training guide explains the evidence relevant to that format and where it is uncertain.
- Does eating gluten-free improve athletic performance?
- No. There is no good evidence that removing gluten improves performance, recovery, energy or inflammation in athletes who do not have coeliac disease or gluten sensitivity. Our kitchen is 100% gluten-free because some people need it to be, not because it is a performance strategy.
- How much protein is in a SmashMeals meal?
- The current menu publishes calories, protein, carbohydrate and fat for each listed meal. Those four fields do not establish sodium, saturated fat, fiber, serving weight, ingredients or allergen suitability. Check the current item details before ordering.
- Can prepared meals cover race-day or in-session fuelling?
- No. Prepared meals cover the everyday breakfasts, lunches and dinners around training. What you consume during a race or long session is a separate plan you should rehearse in training.
- Are these guides medical or sports-nutrition advice?
- No. They summarise published research and official format documentation. For individualised performance or medical nutrition, work with a qualified sports dietitian or clinician.
