Many myths surround sports nutrition and meal timing. Some claim eating every 2-3 hours boosts metabolism, while others swear by intermittent fasting. But what does science actually say?
A recent position stand by the International Society of Sports Nutrition (ISSN) reveals the best nutrient timing strategies for muscle growth, performance, and fat loss. Let’s break down their evidence-based findings.
What Is Nutrient Timing?
Nutrient timing refers to when and what you eat in relation to exercise. It focuses on carbohydrate, protein, and fat intake before, during, and after workouts to optimize muscle recovery, strength, and fat loss.
Key Findings: Meal Timing & Sports Performance
1. Carbohydrate Intake for Energy & Recovery
✔ Maximize glycogen stores with a high-carb diet (8-12 g/kg/day).
✔ High-intensity exercise depletes glycogen stores quickly.
✔ For rapid recovery (<4 hours), consume:
1.2 g/kg/h of carbs (preferably high-glycemic index).
Caffeine (3-8 mg/kg) to enhance uptake.
0.8 g/kg/h of carbs + 0.2-0.4 g/kg/h of protein for faster replenishment.
2. Nutrition for Long Workouts (>60 Min, High Intensity)
✔ Exercise exceeding 60 minutes at >70% VO2max requires 30-60 g carbs/hour.
✔ Best practice: Drink 180-360 ml (6-8% carbs) every 10-15 minutes.
✔ If carb intake is low, adding protein helps with:
Better performance.
Less muscle damage.
Faster glycogen restoration.

3. Strength Training & Carb Timing
✔ Consuming carbs during weightlifting (3-6 sets of 8-12 reps):
Maintains blood sugar (euglycemia).
Boosts glycogen stores.
Improves recovery & long-term muscle growth.
4. Protein Intake for Muscle Growth
✔ Distribute protein intake evenly (every 3-4 hours).
✔ 10g essential amino acids (EAAs) or 20-40g protein per meal enhances muscle protein synthesis (MPS).

5. Pre- & Post-Workout Nutrition
✔ Consuming protein + carbs before and after workouts supports:
Muscle growth.
Fat loss.
Faster recovery.
✔ Pre-workout meal size affects post-workout protein needs.
6. Does Meal Frequency Matter?
✔ Without exercise, meal frequency has minimal effect on weight loss.
✔ However, frequent meals may:
Control hunger.
Improve satiety.
✔ More research is needed on exercise + meal frequency for fat loss.
7. Casein Before Bed for Overnight Muscle Growth
✔ 30-40g casein protein before sleep:
Boosts muscle protein synthesis (MPS) overnight.
Increases metabolic rate without affecting fat burning.
Final Thoughts: Science Over Myths
🚀 You don’t need expensive supplements to apply these strategies—just a well-planned diet!
🔎 Stick to science-based advice instead of fitness myths. If someone claims a "magic meal timing trick," it’s likely not backed by research.
