Protein is the most important macronutrient for body composition. It builds muscle, preserves it during fat loss, and keeps you full. But how much do you actually need? And when should you eat it?

The Simple Daily Target
0.7-1 gram per pound of goal body weight.

That's it. No complicated formulas based on lean body mass or activity multipliers.
Examples:
- Goal weight 180 lbs → 130-180g protein daily
- Goal weight 200 lbs → 140-200g protein daily
- Goal weight 160 lbs → 115-160g protein daily
Use the lower end (0.7g) if you're maintaining or gaining slowly. Use the higher end (1g) if you're cutting or training hard.
Per-Meal Distribution
Your body can only use so much protein at once for muscle building. Spread it across meals.

The 30-40g Rule
Aim for 30-40g protein per meal. This maximizes muscle protein synthesis (MPS)—the process of building muscle.
Meal Breakdown (180g daily target):
- Breakfast: 40g (eggs, Greek yogurt, protein shake)
- Lunch: 50g (chicken, beef, fish)
- Dinner: 60g (larger protein portion)
- Snack: 30g (protein shake, cottage cheese)
Total: 180g. Four eating occasions, each triggering MPS.
Timing Around Workouts
The "anabolic window" is mostly myth. You don't need protein within 30 minutes of training. But timing still matters for optimization.

Pre-Workout (1-2 Hours Before)
Have some protein in your system. You don't want to train fasted if building muscle is the goal.
- 20-30g protein from whole food or shake
- Example: Protein shake or Greek yogurt
Post-Workout (Within 2 Hours)
MPS stays elevated for 24-48 hours after training, but the first meal matters.
- 30-40g high-quality protein
- Whey is ideal (fast absorbing, complete amino acid profile)
- Whole food works too (chicken, eggs, fish)
Before Bed
Casein or slow-digesting protein before bed may help overnight muscle recovery, but it's optional.
- 30-40g casein, cottage cheese, or Greek yogurt
- Or just eat a regular protein-rich dinner
Best Protein Sources

Animal-Based (Complete Proteins)
- Chicken breast: 31g per 4oz
- Lean beef: 28g per 4oz
- Salmon: 25g per 4oz
- Eggs: 6g per large egg
- Greek yogurt: 20g per cup
- Cottage cheese: 25g per cup
- Whey protein: 25g per scoop
Plant-Based (Combine for Complete)
- Lentils: 18g per cup (cooked)
- Black beans: 15g per cup
- Tempeh: 31g per cup
- Tofu: 20g per cup
- Pea protein: 25g per scoop
- Edamame: 17g per cup
Note: Plant proteins are less bioavailable. Vegetarians/vegans should aim for the higher end (1g per lb) of protein targets.
Protein Powder: When to Use It
Whole food is better, but powder has its place:

- Convenience: Quick post-workout when you can't eat a meal
- Filling gaps: When you're short on protein for the day
- Travel: Portable protein source
- Breakfast: Easy way to hit 30-40g in a shake
Don't let powder replace real food. Use it as a supplement, not a staple.
Common Mistakes
1. Eating Most Protein at Dinner
Your body needs protein throughout the day. Eating 80g at dinner doesn't maximize MPS as well as 30g at four meals.
2. Not Eating Enough Breakfast Protein
Cereal, toast, and fruit don't cut it. Start with 30-40g protein to set the tone for the day.
3. Ignoring Protein on Rest Days
Muscle recovery happens on rest days. Keep protein high every day, not just training days.
4. Thinking More Is Always Better
Beyond 1g per pound, there's diminishing returns. You won't build twice as much muscle eating 2g per pound vs 1g per pound.
Quick Reference
| Goal | Target | Per Meal |
|---|---|---|
| Maintenance | 0.7g per lb | 30-40g |
| Muscle gain | 0.8-1g per lb | 30-40g |
| Fat loss | 1g per lb | 30-40g |
Key Takeaways
- Target 0.7-1g protein per pound of goal body weight
- Split across 3-4 meals (30-40g per meal)
- Have protein within 2 hours post-workout
- Prioritize whole food, use powder for convenience
- Keep protein high on rest days
