Sports Nutrition and Hydration Timing Guide

Create a personalized pre-workout, intra-workout, and post-workout nutrition and hydration plan based on your sport, training intensity, and body composition goals.

Prompt Template

You are a certified sports nutritionist. Create a detailed workout nutrition and hydration timing plan for:

**Sport or activity:** [e.g., weightlifting, running, cycling, swimming, CrossFit, team sport]
**Training schedule:** [days per week, time of day, session duration]
**Intensity level:** [moderate / high / competition-level]
**Body composition goal:** [build muscle / lose fat / maintain / improve performance]
**Current weight:** [weight in kg or lbs]
**Dietary restrictions:** [e.g., vegan, gluten-free, lactose intolerant, none]
**Supplement willingness:** [none / basic / open to anything evidence-based]
**Biggest nutrition challenge:** [e.g., no appetite before morning training, stomach issues during exercise, not recovering well]

Provide:

1. **Pre-workout nutrition** — what to eat 2-3 hours before AND 30-60 minutes before, with specific food examples and macros
2. **Intra-workout fueling** — what to consume during training (for sessions over 60 minutes), including hydration with electrolyte guidance
3. **Post-workout recovery window** — what to eat within 30-60 minutes after, with protein and carb targets
4. **Daily hydration formula** — personalized water intake based on bodyweight and training load, with timing cues
5. **Supplement recommendations** — only evidence-based options (creatine, caffeine, electrolytes, etc.) with dosing and timing
6. **Race day or competition nutrition** — modified plan for competition vs. training days
7. **Common mistakes** — 5 nutrition timing errors that hurt performance
8. **Sample day** — a full day of eating around a training session

*Disclaimer: This is general guidance. Consult a registered dietitian for personalized medical nutrition advice.*

Example Output

Sports Nutrition Plan: Morning Weightlifting (6:30 AM) | Goal: Build Muscle

**Bodyweight:** 80 kg | **Training:** 5x/week, 75 min sessions

Pre-Workout

2-3 hours before (if possible):

Whole grain toast with peanut butter + banana + glass of milk

~400 cal | 50g carbs | 20g protein | 15g fat

30 min before (if early morning, stomach-friendly):

Small banana + 10g whey protein in water

~150 cal | 25g carbs | 12g protein

Intra-Workout (75 min session)

- 500-750ml water with a pinch of salt (sodium)

- Sip every 15 minutes, don't chug

- For sessions over 90 min: add 30g fast carbs (sports drink or diluted juice)

Post-Workout (within 45 min)

**Target:** 30-40g protein + 60-80g carbs

Example: Protein shake (30g whey) + large bowl of oatmeal with berries and honey

~550 cal | 75g carbs | 35g protein

Daily Hydration

**Base:** 80 kg × 35ml = 2.8L per day

**Training add-on:** +500ml per hour of exercise

**Total on training days:** ~3.5L

**Timing:** 500ml upon waking, 500ml pre-workout, sip during, 500ml post, rest spread through day

Evidence-Based Supplements

| Supplement | Dose | Timing | Evidence Level |

|-----------|------|--------|----------------|

| Creatine monohydrate | 5g daily | Any time (consistency > timing) | Strong |

| Caffeine | 3-6mg/kg (240-480mg) | 30-60 min pre-workout | Strong |

| Electrolytes (sodium, potassium) | 500-1000mg sodium | During training (hot conditions) | Moderate |

| Whey protein | 25-40g | Post-workout | Strong |

Common Mistakes

1. Training fasted when goal is muscle building — you need fuel to perform and grow

2. Drinking too much water at once instead of sipping throughout the day

3. Skipping carbs post-workout — protein alone isn't enough for recovery

4. Using pre-workout supplements instead of actual food

5. Not adjusting intake on rest days (you still need protein for recovery)

Tips for Best Results

  • 💡Specify your training TIME — nutrition advice for a 6 AM session is very different from a 6 PM session.
  • 💡If you train early morning and can't eat a full meal, ask for a 'minimal stomach' pre-workout option.
  • 💡Don't overthink intra-workout nutrition for sessions under 60 minutes — water is usually enough.
  • 💡Ask for a rest day nutrition plan separately. Recovery nutrition is just as important as training day nutrition.
