Mayo Clinic Weight Loss Formula:
From: | To: |
The Mayo Clinic recommends creating a daily caloric deficit of 500 calories from your Total Daily Energy Expenditure (TDEE) for safe and sustainable weight loss of about 1 pound per week.
The calculator uses the simple formula:
Where:
Explanation: This creates a 3,500 calorie weekly deficit, equivalent to approximately 1 pound of fat loss per week.
Details: A moderate 500-calorie deficit is sustainable and helps preserve muscle mass while promoting fat loss. More aggressive deficits may lead to muscle loss and metabolic adaptation.
Tips: Enter your calculated TDEE (from an online calculator or metabolic testing). For accurate results, ensure your TDEE estimate accounts for your activity level.
Q1: Is 500 calories always the right deficit?
A: For most people, yes. Those with lower TDEE may need a smaller deficit (250-300 calories) to avoid excessively low intake.
Q2: How do I calculate my TDEE?
A: TDEE calculators consider your BMR (basal metabolic rate) multiplied by an activity factor based on your exercise level.
Q3: Should I eat fewer calories for faster weight loss?
A: Not recommended. Larger deficits often lead to muscle loss, nutrient deficiencies, and metabolic slowdown.
Q4: What if I'm not losing weight on this calorie target?
A: Re-evaluate your TDEE calculation, track intake accurately, and consider consulting a dietitian.
Q5: How should I distribute these calories?
A: Focus on protein (1.6-2.2g/kg body weight), healthy fats, and fiber-rich carbs to support satiety and nutrition.
