Calorie Calculation Formula:
| From: | To: |
The calorie calculation formula estimates the daily calorie intake needed to achieve weight loss by subtracting a calorie deficit from your Total Daily Energy Expenditure (TDEE). This approach creates the energy deficit required for fat loss while maintaining adequate nutrition.
The calculator uses the simple formula:
Where:
Explanation: Your TDEE represents the total calories your body burns in a day, including basal metabolic rate and activity. Subtracting a deficit creates the energy imbalance needed for weight loss.
Details: Creating a consistent calorie deficit is the fundamental requirement for weight loss. A deficit of 500-1000 kcal per day typically results in a safe and sustainable weight loss of 0.5-1 kg (1-2 lbs) per week.
Tips: Enter your calculated TDEE and desired calorie deficit. Both values must be positive numbers. For sustainable weight loss, aim for a deficit that doesn't drop your daily intake below 1200 kcal for women or 1500 kcal for men.
Q1: How do I calculate my TDEE?
A: TDEE can be estimated using online calculators that consider your age, gender, weight, height, and activity level, or measured through professional metabolic testing.
Q2: What's a safe calorie deficit for weight loss?
A: A deficit of 500-1000 calories per day is generally safe and sustainable, resulting in 0.5-1 kg (1-2 lbs) of weight loss per week.
Q3: Can I create too large of a calorie deficit?
A: Yes, excessively large deficits can lead to muscle loss, nutrient deficiencies, metabolic adaptation, and are difficult to maintain long-term.
Q4: Should I adjust my calorie target as I lose weight?
A: Yes, as you lose weight, your TDEE decreases, so you may need to recalculate your needs periodically to continue progress.
Q5: Is calorie counting the only factor for weight loss?
A: While calorie balance is fundamental, nutrient quality, meal timing, macronutrient distribution, and exercise type also impact body composition and health.
