Why am I not losing weight despite a strict, accurately calculated 500 calorie deficit diet?


 Losing weight boils down to one key rule: burn more calories than consume. But how do you know exactly how many calories to cut? That’s where a calorie deficit calculator comes in—a tool that takes the guesswork out of weight loss.

At NutritDiet, we make it easy with our free Calorie Deficit Calculator, designed to give you a personalized calorie target for safe, sustainable fat loss. Here’s how it works and why it’s a game-changer.

What Is a Calorie Deficit Calculator?

A calorie deficit calculator estimates how many calories you need to eat daily to lose weight based on:

  • Your body stats (age, weight, height, gender)

  • Activity level (sedentary, active, athlete)

  • Weight loss goals (e.g., 0.5kg or 1lb per week)

It crunches the numbers so you don’t have to!

How Does It Calculate Your Deficit?

1. Determines Your TDEE (Total Daily Energy Expenditure)

Your TDEE is the calories you burn daily, including:

  • BMR (Basal Metabolic Rate): Calories burned at rest.

  • Activity calories: From walking, workouts, etc.

2. Subtracts a Safe Deficit

For healthy weight loss (0.5–1lb/week), the calculator subtracts 10–20% from your TDEE. Extreme deficits can backfire—our tool keeps you in the safe zone.

3. Gives Your Daily Calorie Goal

Example: If your TDEE is 2,500 calories, a 20% deficit means eating 2,000 calories/day.

Try our Calorie Deficit Calculator to get your custom number in seconds!

Why Use NutritDiet’s Calculator?

✅ Personalized for YOU – No generic estimates.
✅ Science-Backed – Uses the latest TDEE formulas.
✅ Free & Easy – No signup needed.

3 Tips to Maximize Your Calorie Deficit

  1. Track Accurately – Use apps like MyFitnessPal alongside our calculator.

  2. Prioritize Protein – Keeps you full and preserves muscle.

  3. Adjust as You Lose Weight – Recalculate every 4–6 weeks.

Related FAQs About Calorie Deficit Calculators

1. How much of a calorie deficit is safe for weight loss?

A 10–20% deficit below your TDEE is ideal for losing 0.5–1 lb (0.2–0.5 kg) per week. Larger deficits can cause muscle loss, fatigue, and metabolic slowdown.

2. Do I need to track calories every day?

Not necessarily! While tracking helps accuracy, you can use portion control and mindful eating if logging feels tedious. Our Calorie Deficit Calculator gives you a baseline to work from.

3. Will a calorie deficit calculator work for muscle gain?

Yes! Just reverse the math—eat 10–20% above your TDEE while prioritizing protein and strength training.

4. Why isn’t my weight budging despite a deficit?

Common reasons:

  • Underestimating intake (hidden calories in oils, sauces).

  • Water retention (from salt, carbs, or workouts).

  • Metabolic adaptation (your body adjusts over time).

Recalculate your TDEE every few weeks if progress stalls.

5. Can I eat anything as long as I’m in a deficit?

Technically, yes—but nutrient-dense foods (protein, fiber, healthy fats) keep you fuller and healthier than empty calories.

Final Thoughts: Sustainable Weight Loss Made Simple

A calorie deficit is the foundation of fat loss, but how you create it matters. Instead of extreme cuts:

Weight loss isn’t about starvation—it’s about working smarter, not harder. Ready to take the guesswork out of your diet? Find your ideal calorie target in seconds:
