📌 How Many Calories Should I Eat Per Day? (By Age, Gender & Activity)
The answer depends on your unique profile. According to the CDC, adult women typically need 1,600–2,400 calories daily, while adult men need 2,000–3,000 calories. However, our calorie calculator below gives you a personalized number. Use the table below as a quick reference:
| Gender & Age | Sedentary | Moderately Active | Active |
|---|---|---|---|
| Female 19-30 | 2,000 | 2,200 | 2,400 |
| Female 31-50 | 1,800 | 2,000 | 2,200 |

⚙️ How This Calorie Calculator Works (Mifflin-St Jeor Formula)
We use the Mifflin-St Jeor equation, proven by the CDC to be the most accurate for non-obese adults. It calculates your Basal Metabolic Rate (BMR) — calories burned at rest — then multiplies by your activity level to get TDEE (Total Daily Energy Expenditure). For weight loss, we subtract 500 calories (safe deficit). For muscle gain, we add 400 calories (clean surplus). The result is your personalized daily calorie intake.
📈 Zigzag Calorie Cycling – Break Weight Loss Plateaus
If you've hit a plateau, try alternating high-calorie and low-calorie days. For example, eat at maintenance 3 days a week, and at a deficit 4 days. This prevents metabolic adaptation. Our calorie deficit calculator gives you the baseline; you can manually adjust daily targets.
📊 Understanding Your Results: Maintenance, Deficit & Surplus
After you click "Calculate", you'll see three key numbers:
- Maintenance calories (TDEE): The exact calories to keep your current weight.
- Weight loss calories: TDEE minus 500 kcal – leads to ~0.5 kg loss per week.
- Weight gain calories: TDEE plus 400 kcal – supports lean muscle growth when combined with strength training.
⚠️ Never go below 1,200 calories (women) or 1,500 calories (men) without medical supervision.
