Reviewed by Dr. Michael Torres, PhD
Quick Answer (as of 2026): A 155 lb woman aiming for maintenance needs approximately 2138 cal / 140g protein / 273g carbs / 54g fat — based on Mifflin-St Jeor BMR (~1379 cal), moderate activity TDEE (~2138 cal), and a 0-calorie maintenance match.
Daily Macros for a 155 lb Woman (Maintenance)
| Macro | Amount | % of Calories |
|---|---|---|
| Calories | 2138 | 100% |
| Protein | 140g | 26% |
| Carbs | 273g | 51% |
| Fat | 54g | 23% |
These macros use the Mifflin-St Jeor equation (the most validated BMR formula) plus standard sports nutrition ratios.
How to Hit These Macros
A practical day for a 155 lb woman:
- Breakfast (~35g protein): 3 eggs + 1/2 cup oats + Greek yogurt + berries
- Lunch (~42g protein): 4.6 oz grilled chicken + sweet potato + large salad
- Dinner (~42g protein): 4.6 oz salmon + rice + roasted vegetables
- Snack (~21g protein): Protein shake or cottage cheese with fruit
Adjust food choices as you like — what matters is hitting the totals consistently.
Common Mistakes at 155 lb
- Overestimating activity level — If you’re sedentary not “moderately active,” your TDEE is lower and these macros are too high.
- Not recalculating after weight changes — At 150 lb your macros will be slightly different. Recalculate every 10-15 lbs.
- Skipping protein consistency — Hitting 140g protein 5/7 days and “winging” 2 days = 71% adherence = 71% of the result.
Frequently Asked Questions
Is 2138 calories enough for a 155 lb woman?
For maintenance, yes — this is a sustainable maintenance that protects metabolism. Going lower can backfire long-term.
How long until results show?
Visible body composition changes take 4-6 weeks. Scale weight changes are visible in 1-2 weeks but fluctuate daily — use weekly averages.
Should I cycle macros on workout days?
For most people, no — daily macros work fine. Advanced cyclers tweak this but it’s fine-tuning, not the starting point.
