Macronutrient Calculation Formulas:
From: | To: |
The Daily Macro Calculator estimates your Basal Metabolic Rate (BMR), Total Daily Energy Expenditure (TDEE), and optimal macronutrient distribution for weight loss based on your personal metrics and activity level.
The calculator uses the following formulas:
Where:
Explanation: The calculator first determines your BMR (calories burned at rest), then adjusts for activity level to get TDEE, and finally creates a 500-calorie deficit for weight loss with a balanced macronutrient distribution.
Details: Proper macronutrient distribution ensures you lose weight while maintaining muscle mass, energy levels, and overall health. The 25% protein, 55% carbs, 20% fat ratio is a balanced approach for sustainable weight loss.
Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, measure your weight and height precisely and be honest about your activity level.
Q1: Why a 500-calorie deficit?
A: A 500-calorie daily deficit typically results in about 0.5kg (1lb) of weight loss per week, which is considered safe and sustainable.
Q2: Can I adjust the macronutrient ratios?
A: Yes, some people prefer higher protein or lower carb ratios, but the provided ratios work well for most people.
Q3: How accurate is the BMR calculation?
A: The Mifflin-St Jeor equation used here is about 90% accurate for most people, but individual variations exist.
Q4: Should I eat back exercise calories?
A: No, the activity factor already accounts for your exercise level. Eating back calories would eliminate your deficit.
Q5: When should I recalculate my macros?
A: Recalculate every 5-10kg of weight loss or if your activity level changes significantly.
