📌 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:

⚙️ 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.

❓ Frequently Asked Questions (Google Rich Results Enabled)

❓ How many calories should I eat to lose weight?
Use the "lose weight" option above. A deficit of 300-500 calories below maintenance leads to 0.5 kg loss per week. For faster but safe loss, stay within 1,200-1,500 kcal minimum.
❓ How do I calculate my daily calorie needs?
Enter your age, gender, weight, height, activity level, and goal in the calorie calculator above. It automatically computes your BMR and TDEE.
❓ What is a calorie deficit and how does it work?
A calorie deficit means eating fewer calories than your body burns. This forces your body to use stored fat for energy, leading to weight loss.
❓ Is this calorie calculator accurate?
Yes – it uses the Mifflin-St Jeor equation, which has a 90% accuracy rate compared to lab measurements. Individual metabolism can vary by ±10%.
❓ How many calories should I eat to maintain my weight?
Select "maintain weight" in the calculator. Your maintenance calories (TDEE) will be displayed immediately.
❓ Does activity level change calorie needs?
Absolutely. A highly active person can burn up to 1,000 more calories daily than a sedentary person of the same age/weight.
❓ Should I use BMR or TDEE for calorie planning?
Always use TDEE (Total Daily Energy Expenditure) for meal planning, as it includes activity. BMR is just resting energy.
