Calories Calculation Formula:
From: | To: |
This calculator determines how many calories you should eat daily to lose 10 pounds over a specified time period. It's based on the principle that 1 pound of fat equals approximately 3500 calories, so 10 pounds equals 35,000 calories.
The calculator uses the following formula:
Where:
Explanation: The formula calculates the daily calorie deficit needed to lose 10 pounds over your chosen time frame, then subtracts this from your maintenance calories.
Details: Creating a consistent calorie deficit is essential for sustainable weight loss. This calculator helps you plan a realistic timeline for losing 10 pounds while maintaining adequate nutrition.
Tips: Enter your accurate TDEE (use a TDEE calculator if unsure) and choose a realistic time frame. A safe weight loss rate is 1-2 pounds per week. All values must be valid (TDEE > 0, days ≥ 1).
Q1: Is 3500 calories really equal to 1 pound of fat?
A: This is a widely accepted estimate, though individual metabolism and body composition can cause slight variations.
Q2: What's a safe time frame to lose 10 pounds?
A: 5-10 weeks is generally considered safe and sustainable for losing 10 pounds (1-2 pounds per week).
Q3: Should I go below 1200 calories per day?
A: It's generally not recommended to go below 1200 calories for women or 1500 for men without medical supervision.
Q4: What if my calculated calories seem too low?
A: Extend your time frame or incorporate exercise to increase your TDEE rather than creating an extreme deficit.
Q5: Does this account for metabolic adaptation?
A: No, as you lose weight, your TDEE may decrease, so you may need to recalculate periodically.
