Caloric Deficit Formula:
From: | To: |
A caloric deficit of 1000 kcal per day is required to lose 2 pounds per week, based on the principle that 1 pound of fat equals approximately 3500 kcal. This creates a weekly deficit of 7000 kcal (2 × 3500 kcal).
The calculator uses the following formula:
Where:
Explanation: This calculation provides the daily caloric intake needed to create a consistent deficit for steady weight loss of 2 pounds per week.
Details: Creating a consistent caloric deficit is the fundamental principle behind weight loss. A 1000 kcal daily deficit is considered aggressive but sustainable for many individuals seeking significant weight loss.
Tips: Enter your accurate TDEE value. For best results, use a TDEE calculator that accounts for your age, weight, height, activity level, and gender. Ensure your calculated daily intake doesn't fall below 1200 kcal for women.
Q1: Is losing 2 pounds per week safe?
A: For most overweight individuals, 2 pounds per week is considered safe and effective. However, consult a healthcare provider if you have underlying health conditions.
Q2: What if my calculated intake is below 1200 kcal?
A: Do not consume fewer than 1200 kcal daily without medical supervision. Consider a smaller deficit or incorporate more physical activity instead.
Q3: How accurate is the 3500 kcal per pound rule?
A: While it's a good general guideline, individual metabolism variations may affect actual weight loss. Monitor your progress and adjust as needed.
Q4: Should I adjust my intake as I lose weight?
A: Yes, as you lose weight, your TDEE decreases. Recalculate your TDEE every 4-6 weeks to maintain the appropriate deficit.
Q5: What about macronutrient distribution?
A: While total calories matter most for weight loss, adequate protein intake (1.6-2.2g/kg) helps preserve muscle mass during weight loss.
