What to eat before, during and after training — evidence on carbohydrate and protein timing, practical meal ideas and when timing matters most.
Learning objectives
- Plan pre-exercise meals by timing and session type
- Prescribe carbohydrate during exercise by duration
- Plan post-exercise recovery nutrition
- Identify when nutrient timing matters most
Before this lesson
Why this matters
The right food at the right time improves training quality and recovery, especially when sessions are long, intense or close together.
Before exercise
- 1–4 g/kg carbohydrate 1–4 h before key sessions [thomas2016].
- Closer to training: smaller, lower fat and fibre to limit gut discomfort.
- Indian examples: idli with sambar, poha, banana with curd, toast and peanut butter.
During exercise
Jeukendrup’s duration-based guidelines [jeukendrup2014]:
| Duration | Carbohydrate |
|---|---|
| <45 min | Not needed |
| 45–75 min | Small amounts or mouth rinse |
| 1–2 h | Up to 30 g/h |
| 2–3 h | Up to 60 g/h |
| >2.5 h | Up to 90 g/h, glucose + fructose |
Train the gut — practise race nutrition in training.
After exercise
- Protein: ~0.25–0.4 g/kg (≈20–40 g) within a few hours, and every 3–4 h across the day [jager2017].
- Carbohydrate: if the next session is within ~8 h, ~1.0–1.2 g/kg/h for the first 4 h restores glycogen fastest; otherwise normal meals suffice [kerksick2017].
Common mistakes and misconceptions
Case study
A badminton player has matches at 10:00 and 15:00. Plan: breakfast at 07:30 (upma, eggs, juice); after match 1, a sandwich, banana and milk (carbohydrate + protein); sips of sports drink before match 2. Energy in the second match improves compared with previous tournaments.

Short-answer & application questions
- Plan nutrition for a 6 a.m. swim session and a 5 p.m. gym session on the same day.
- Design race nutrition for a 3-hour cycling event.
- Suggest Indian post-workout snacks providing ~25 g protein and carbohydrate.
Key takeaways
- Pre-exercise: 1–4 g/kg carbohydrate 1–4 h before key sessions; smaller, lower-fibre meals closer to training.
- During: 30–60 g/h for 1–2.5 h efforts; up to 90 g/h of mixed carbohydrates for longer events.
- After: ~0.3 g/kg protein and carbohydrate; rapid glycogen restoration matters when sessions are <8 h apart.
- Total daily intake matters most; timing fine-tunes it.
