Weight Loss Equation:
From: | To: |
The Weight Loss Calculator estimates your daily calorie needs for sustainable weight loss based on your Basal Metabolic Rate (BMR) and activity level. It creates a 500-calorie daily deficit for safe and effective weight loss of about 0.5-1 kg per week.
The calculator uses the weight loss equation:
Where:
Explanation: The equation calculates your total daily energy expenditure and subtracts 500 calories to create a deficit that promotes weight loss while maintaining adequate nutrition.
Details: A 500-calorie daily deficit is recommended by health professionals as it leads to sustainable weight loss of about 0.5-1 kg per week without causing excessive hunger or nutrient deficiencies.
Tips: Enter your BMR (use a BMR calculator if unknown), select your activity level, and the calculator will determine your daily calorie target for weight loss. All values must be valid (BMR > 0).
Q1: What is BMR and how do I calculate it?
A: BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest. Use online BMR calculators that consider age, gender, height, and weight.
Q2: Is a 500-calorie deficit safe for everyone?
A: While generally safe for most adults, individuals with specific health conditions should consult a healthcare provider before starting a calorie-restricted diet.
Q3: How quickly will I lose weight with this deficit?
A: A 500-calorie daily deficit typically results in about 0.5-1 kg (1-2 pounds) of weight loss per week.
Q4: Should I adjust my calorie intake as I lose weight?
A: Yes, as you lose weight, your BMR decreases. Recalculate your needs every 4-6 weeks or after significant weight loss.
Q5: What if I'm very active or an athlete?
A: Highly active individuals may need a smaller deficit to maintain energy levels and performance. Consult a sports nutritionist for personalized advice.
