Calorie Calculator

A calorie calculator estimates how many calories you need each day based on your body stats and activity level. It calculates your Total Daily Energy Expenditure (TDEE) — the total calories your body burns in 24 hours — and then suggests three targets:

• Maintenance Calories: Eat this much to keep your current weight stable.
• Weight Loss Calories: A 500 kcal daily deficit for roughly 0.5 kg/week fat loss.
• Weight Gain Calories: A 500 kcal daily surplus for lean muscle building.

The calculation is based on the Mifflin-St Jeor equation for BMR (Basal Metabolic Rate), multiplied by an activity factor (Harris-Benedict principle). This gives the most scientifically validated daily calorie estimate available without laboratory testing.

Whether you want to lose weight for a wedding, gain muscle for sports, or simply eat healthily, knowing your daily calorie target is the most important first step.

1. Enter your weight in kg. Use your current body weight, not your target weight.
2. Enter your height in cm (remove footwear when measuring).
3. Enter your age in years. Metabolism slows naturally with age, so this matters.
4. Select your biological sex — male and female bodies have different metabolic baselines.
5. Choose your activity level honestly:
   • Sedentary: Office job, drive everywhere, no gym
   • Lightly Active: Walk 20–30 min/day or gym 1–3×/week
   • Moderately Active: Gym 3–5×/week or a physically active job
   • Very Active: Hard training 6–7×/week or manual labour job
6. Click Calculate to see your BMR, maintenance calories, weight-loss target, and weight-gain target.

Tip: Most people overestimate their activity level. If in doubt, choose the level below what you think you are — it is safer and more accurate.

Calorie counting has a decades-long scientific track record for weight management. A consistent daily deficit of 500 kcal leads to approximately 0.5 kg of fat loss per week — this is backed by thermodynamics and clinical research. It is not magic; it is math.

But calorie counting does not mean bland food. Indian cuisine is highly calorie-dense due to cooking oils (ghee, coconut oil, mustard oil), portion sizes (full plates of rice, multiple rotis), and calorie-rich snacks (samosas, pakoras, mithai). Many Indians unknowingly eat 500–800 calories more than their TDEE without realising it.

Common high-calorie Indian foods to watch:

• 1 tablespoon ghee = ~120 kcal
• 1 samosa = ~250–300 kcal
• 1 plate biryani (restaurant) = ~550–700 kcal
• 1 ladoo = ~150–200 kcal
• 250 ml whole milk = ~150 kcal

You do not need to give up any of these. You just need to know your calorie budget and spend it wisely. That is exactly what this calculator helps you do.
