Weight Loss Calorie Formula:
| From: | To: |
The Workout Calculator For Weight Loss estimates daily calorie intake required for effective weight loss based on your Basal Metabolic Rate (BMR). It calculates a calorie deficit that promotes sustainable weight loss while maintaining energy levels for workouts.
The calculator uses the weight loss calorie formula:
Where:
Explanation: This formula calculates your Total Daily Energy Expenditure (TDEE) with light activity and subtracts 500 calories to create a sustainable weight loss deficit.
Details: Accurate calorie calculation is essential for effective weight loss. A 500-calorie daily deficit typically results in losing about 1 pound per week, which is considered safe and sustainable. This approach ensures you lose fat while preserving muscle mass.
Tips: Enter your BMR in kilocalories (kcal). Your BMR can be calculated using various formulas or measured through specialized testing. Ensure the BMR value is accurate for best results.
Q1: Why subtract 500 calories specifically?
A: A 500-calorie daily deficit creates a 3500-calorie weekly deficit, which equals approximately 1 pound of fat loss per week (since 1 pound of fat = 3500 calories).
Q2: What if I'm more active than sedentary?
A: For moderate activity (3-5 days/week), use multiplier 1.375; for heavy activity (6-7 days/week), use 1.55; for athletes, use 1.725 or higher.
Q3: Is this calorie target safe for everyone?
A: Women should generally not go below 1200 calories daily, and men not below 1500 calories without medical supervision. Adjust based on individual needs.
Q4: How often should I recalculate my calories?
A: Recalculate every 10-15 pounds lost, as your BMR decreases with weight loss. Also adjust if your activity level changes significantly.
Q5: What about macronutrients?
A: While total calories matter most for weight loss, aim for adequate protein (0.7-1g per pound of body weight) to preserve muscle during weight loss.
