Calorie & Macro Calculator: BMR, TDEE, Goals — Offline HTML

HOW MANY CALORIES YOU PERSONALLY NEED — AND HOW TO SPLIT THEM ACROSS PROTEINS, FATS AND CARBS

Enter weight, height and age — the calculator computes basal metabolic rate with two scientific formulas, adds an activity coefficient and shows the calorie targets for three goals with a protein/fat/carb breakdown.

EXAMPLE FROM THE SCREENSHOT (real calculation of the program):
• Male, 82 kg, 178 cm, 32 years, moderate activity
• BMR (Mifflin-St Jeor): 1778 kcal · (Harris-Benedict): 1864 kcal
• TDEE (maintenance): 2755 kcal/day
• For weight loss: 2255 kcal/day · for muscle gain: 3155 kcal/day

WHAT´S INSIDE (one index.html file):
• Two BMR formulas: Mifflin-St Jeor and Harris-Benedict
• Five activity levels — from sedentary to physical work plus sports
• Three goals: weight loss (−500), maintenance, muscle gain (+400)
• Macro split: 30% protein / 30% fat / 40% carbohydrates
• BMI interpreted on the WHO scale
• Water norm: 30 ml per kg of weight
• Separate formulas for men and women

WHO IT´S FOR:
Fitness enthusiasts and nutritionists. Most online calculators show one number without explaining where it came from — here both formulas sit side by side.
