π What should you eat to reach your goals? Enter your details to calculate your daily calorie needs, optimal macronutrient breakdown (protein/carbs/fat), personalized meal plans, and supplement recommendations. Based on USDA guidelines and sports nutrition science for weight loss, muscle gain, or healthy maintenance.
The nutrition calculator estimates daily macronutrient and micronutrient requirements based on body weight, height, age, sex, and activity level. It applies USDA Dietary Guidelines and National Academies Dietary Reference Intake values.
Formula & Methodology
Protein RDA = 0.8 g Γ body weight (kg). Carbohydrate RDA = 130 g/day minimum. Fat: 20-35% of total energy intake. Total energy = TDEE calculated via Mifflin-St Jeor BMR Γ activity factor.

How do I calculate my daily protein, carbs, and fat needs?
Use our Nutrition Calculator to determine your optimal macronutrient breakdown. Based on your goals, activity level, and body metrics, we calculate precise protein, carbohydrate, and fat requirements.
What's the difference between BMR and TDEE in nutrition planning?
BMR is calories burned at complete rest. TDEE includes BMR plus activity calories. Our calculator determines both for effective nutrition planning.
π¬ Scientific Methodology - How We Calculate Nutrition Plans
1
Basal Metabolic Rate (BMR) Calculation
Using Mifflin-St Jeor Equation (most accurate) for resting energy expenditure.
2
Total Daily Energy Expenditure (TDEE)
BMR multiplied by activity factor for total calorie needs.
3
Goal-Specific Calorie Targets
Adjust TDEE based on weight loss, maintenance, or muscle gain goals.
4
Macronutrient Distribution
Optimal ratios based on goals and activity levels.
β Nutrition Frequently Asked Questions
How do I calculate my daily protein, carbs, and fat needs? βΌ
Step-by-step calculation: 1) Determine calorie needs based on TDEE and goals, 2) Set protein at 1.6-2.2g/kg body weight, 3) Allocate fats at 0.8-1.2g/kg, 4) Fill remaining calories with carbohydrates. Our calculator automates this with precision.
What's the difference between BMR and TDEE in nutrition planning? βΌ
BMR (Basal Metabolic Rate) = calories burned at complete rest. TDEE (Total Daily Energy Expenditure) = BMR + activity calories. Nutrition planning uses TDEE for calorie targets.
How much protein do I really need for muscle building? βΌ
Research shows 1.6-2.2g protein/kg body weight optimizes muscle protein synthesis. For a 70kg person: 112-154g daily.
