How To Eat For Performance | Tim Briggs

Tim Briggs is a nutritionist, CrossFit coach and the owner of WeDominateNutrition.com Most people with a gym membership have an idea of how to eat to facilitate weight change, but eating to maximise performance output is a another beast entirely. Today, expect to learn how to use diet to boost your strength, endurance or recovery, Tim's favourite protocols for eating around training & competitions, why the FODMAP diet is probably right for almost all of us and whether he's ever fully going to grow a topknot.

CHAPTERS

  1. 0:00 – 2:32

    Performance nutrition framework: health first, then energy balance

    Chris sets up the problem of eating for performance across different sports, and Tim explains his first principles approach. He starts with health foundations (micronutrients) alongside overall energy needs before worrying about sport-specific tweaks.

  2. 2:32 – 4:53

    Why CrossFit and high intensity break standard TDEE assumptions

    Tim explains why typical calorie calculators often underestimate needs for high-intensity athletes. He highlights the compounding activity around training and the extended post-workout energy demand (after-burn).

  3. 4:53 – 7:34

    Fixing the ‘no greens’ problem: simple micronutrient habits

    They discuss the most common deficiency pattern Tim sees—lack of greens—and practical ways to add micronutrients without overcomplicating meals. The focus is on low-friction routines and a balanced plate structure.

  4. 7:34 – 9:01

    Meal composition basics: where fats fit (and why avocado is controversial)

    Chris pushes on the ‘thirds’ meal rule and asks where fats belong. Tim explains that fats often come from protein sources, plus add-ons like nuts or avocado, then they detour into food preferences and practicality.

  5. 9:01 – 10:46

    Energy systems made practical: why carbs dominate most sports

    Tim maps sport demands onto energy systems and shows that carbohydrates are central across most intensities and durations. Strength sports, CrossFit, and endurance differ in emphasis, but carbs remain a consistent fuel lever.

  6. 10:46 – 15:55

    Keto & paleo for performance: why they often underfuel athletes

    Chris asks how keto athletes manage long events, and Tim argues keto is rarely optimal for performance. They also break down paleo’s logic and explain why it commonly fails CrossFitters due to insufficient carbohydrate intake.

  7. 15:55 – 23:43

    Timing nutrition around training: pre, immediate pre, intra, post

    Tim lays out a structured window-based approach for training days: pre-meal, immediate pre, intra-workout support, and post-workout recovery. He gives concrete example foods, approximate quantities, and explains why fat timing matters.

  8. 23:43 – 32:04

    High-carb reality: using liquid carbs and creatine to hit performance targets

    They discuss how elite athletes reach very high carb intakes and why it’s hard for normal people to replicate. Chris frames maltodextrin/dextrose as an easy compliance tool, and Tim connects it to glycogen and creatine replenishment.

  9. 32:04 – 36:25

    Competition week strategy: carb-load without changing foods

    Tim explains how nutrition shifts in the lead-up to competition: keep foods familiar, minimize gut issues, and progressively increase carbohydrate intake. He also explains why uncontrolled sugar ‘smashing’ at comps is suboptimal compared to planned timing.

  10. 36:25 – 45:27

    Gut performance & the FODMAP elimination approach

    They introduce FODMAPs as a practical framework to reduce digestive distress and inflammation, especially around competition. Tim emphasizes individual tolerance and recommends a gradual elimination-and-reintroduction process to identify triggers.

  11. 45:27 – 57:07

    Dieting vs performance: intermittent fasting tradeoffs and smarter deficits

    Chris describes his current cut using intermittent fasting and fasted training, and Tim contrasts fat-loss convenience with performance costs. They then move into principles for sustainable deficits and why scale weight is a noisy metric.

  12. 57:07 – 1:03:33

    Weight classes and making weight without destroying performance

    Tim explains his preferred approach for weight-category sports: arrive near stage weight weeks in advance rather than relying on extreme dehydration. They compare this to MMA-style cuts and argue for health-first competition preparation.

  13. 1:03:33 – 1:28:13

    Final toolkit: hydration, electrolytes, sleep supplements, and fad-diet skepticism

    They close with practical add-ons: hydration targets, electrolyte strategies, sleep-support supplements, and protein guidelines. The conversation ends by critiquing fad diets and reinforcing a sustainable micro+macro approach with flexibility.
