From: | To: |
This calculator helps determine your daily calorie needs for weight loss by creating a 500-calorie deficit from your maintenance calories. It also provides macronutrient breakdown (40% carbs, 30% protein, 30% fat) for optimal weight loss.
The calculator uses these formulas:
Where:
Explanation: The 500-calorie deficit creates about 1 pound of fat loss per week. The 40/30/30 macro ratio helps maintain muscle while losing fat.
Details: A moderate calorie deficit is crucial for sustainable weight loss. Too large a deficit can lead to muscle loss and metabolic slowdown.
Tips: Enter your BMR (use a BMR calculator if unknown) and select your activity level. For accurate results, be honest about your activity level.
Q1: Why a 500-calorie deficit?
A: A 500-calorie daily deficit equals about 1 pound of fat loss per week, which is a safe and sustainable rate.
Q2: What if I don't know my BMR?
A: Use a BMR calculator that considers your age, gender, weight, and height for estimation.
Q3: Is the 40/30/30 ratio best for everyone?
A: While effective for most, some may benefit from different ratios based on individual needs and preferences.
Q4: Can I adjust the deficit?
A: Yes, but deficits larger than 500-750 calories/day are not recommended without medical supervision.
Q5: How often should I recalculate?
A: Recalculate every 10-15 pounds lost or if your activity level changes significantly.
