कैलोरी / TDEE कैलकुलेटर

कैसे Use करें?

1. 1Gender select करें — male/female (Mifflin–St Jeor formula में gender-specific offset होता है: male +5, female −161)
2. 2Age डालें (10-100 साल range) — उम्र के साथ metabolism slow होती है, इसलिए ज़रूरी input है
3. 3वज़न (Weight) kg में डालें — सुबह खाली पेट सबसे accurate baseline (overnight fast के बाद)
4. 4लंबाई (Height) डालें — cm में या feet+inches में (toggle से switch करें)
5. 5Activity level चुनें — 5 levels: Sedentary (desk job, exercise नहीं) से लेकर Extra Active (athlete, दिन में 2 बार training)
6. 6Result automatic दिखेगा — BMR (बस ज़िंदा रहने के लिए) + TDEE (actually daily burn) + cut/maintain/bulk calories + macro split (protein/carb/fat grams में)
7. 7Cut goal: TDEE से 500 kcal कम = हफ्ते में ~0.5 kg fat loss (safe sustainable rate), Maintain = same weight, Bulk: +300 kcal surplus = lean muscle gain with strength training
8. 8Result screenshot लेकर dietitian/doctor visit में share करें — proper nutrition plan बनवाने के लिए baseline reference

कैलोरी / TDEE कैलकुलेटर क्या है?

## Calorie / TDEE Calculator kya hai Calorie / TDEE Calculator एक scientific nutrition tool है जो आपकी body की <strong>daily energy needs</strong> को precisely calculate करता है। यह सिर्फ '2,000 कैलोरी रोज़ खाओ' वाली generic advice नहीं — यह आपकी specific body composition (age, gender, weight, height, activity level) के हिसाब से customized calorie target देता है। Tool 3 key numbers देता है: (1) <strong>BMR (Basal Metabolic Rate)</strong> — अगर आप पूरा दिन बिस्तर पर पड़े रहो, तब भी आपकी body जितनी calories burn करेगी (heartbeat, breathing, brain function, organ operation, cell regeneration), (2) <strong>TDEE (Total Daily Energy Expenditure)</strong> — BMR + आपकी daily physical activity = actual calories जो रोज़ burn होती हैं, (3) <strong>Cut / Maintain / Bulk goals</strong> — आपके fitness goal के हिसाब से recommended daily calories + macros (protein, carbs, fat grams में)। Formula <strong>Mifflin–St Jeor equation</strong> है — 1990 में MD Mifflin और ST St Jeor ने publish की, यह आज <strong>ACSM (American College of Sports Medicine)</strong> + Academy of Nutrition and Dietetics के द्वारा officially endorsed है, और research में सबसे accurate (4-5% error margin, older Harris-Benedict formula 10% error margin देती है)। Mifflin–St Jeor की key insight — direct gender + body weight + height + age से BMR predict होती है, body fat % measurement की ज़रूरत नहीं। ## Kaise kaam karta hai <strong>BMR Formula (Mifflin–St Jeor):</strong> - <strong>Males:</strong> BMR = (10 × weight kg) + (6.25 × height cm) − (5 × age years) + 5 - <strong>Females:</strong> BMR = (10 × weight kg) + (6.25 × height cm) − (5 × age years) − 161 <strong>TDEE Formula:</strong> TDEE = BMR × Activity Multiplier। <strong>Activity Multipliers (Harris-Benedict standardized):</strong> Sedentary (desk job, no exercise) = 1.2 · Light (1-3 days exercise/wk) = 1.375 · Moderate (3-5 days) = 1.55 · Very Active (6-7 days) = 1.725 · Extra Active (athlete, twice-daily training) = 1.9। <strong>Example:</strong> 28-year-old Indian male, 70 kg, 172 cm, moderate activity। BMR = (10 × 70) + (6.25 × 172) − (5 × 28) + 5 = 700 + 1075 − 140 + 5 = <strong>1,640 kcal</strong>। TDEE = 1640 × 1.55 = <strong>2,542 kcal/day</strong>। Cut goal (weight loss) = 2542 − 500 = 2,042 kcal। Maintain = 2,542 kcal। Bulk = 2542 + 300 = 2,842 kcal। <strong>Macro split (default balanced):</strong> 30% Protein · 40% Carbs · 30% Fat। Protein = 4 kcal/g, Carbs = 4 kcal/g, Fat = 9 kcal/g। Example for 2,542 kcal maintain: Protein = (2542 × 0.30) ÷ 4 = 191g, Carbs = (2542 × 0.40) ÷ 4 = 254g, Fat = (2542 × 0.30) ÷ 9 = 85g। ## 5 real examples **1. Average Indian male IT professional, 28 yrs, 70 kg, 5'8" (172 cm), Sedentary (desk job, no exercise):** BMR = 1,640 kcal। TDEE = 1640 × 1.2 = 1,968 kcal। Maintain ~2,000 kcal, Cut 1,500 kcal (अगर weight loss चाहिए — moderate caloric deficit), Bulk 2,300 kcal। Protein target 75-105g (1.0-1.5 g/kg)। Reality check — most Indian IT professionals 2,500+ kcal consume करते हैं (rice-heavy meals, evening snacking) → weight gain। **2. Indian female teacher, 35 yrs, 60 kg, 5'3" (160 cm), Light activity (morning walk):** BMR = (10 × 60) + (6.25 × 160) − (5 × 35) − 161 = 600 + 1000 − 175 − 161 = 1,264 kcal। TDEE = 1264 × 1.375 = 1,738 kcal। Maintain 1,738 kcal, Cut 1,238 kcal (very low — better add exercise instead of cutting further), Bulk 2,038 kcal। Protein 95-120g (1.6-2.0 g/kg, especially during weight management)। **3. Young gym enthusiast, 22 yrs, male, 75 kg, 5'10" (178 cm), Very Active (6-day gym + cardio):** BMR = (10 × 75) + (6.25 × 178) − (5 × 22) + 5 = 750 + 1112.5 − 110 + 5 = 1,757 kcal। TDEE = 1757 × 1.725 = 3,031 kcal। Maintain 3,031 kcal, Cut 2,531 kcal (lean cut), Bulk 3,331 kcal। Protein 120-150g for muscle gain (1.6-2.0 g/kg)। **4. Indian housewife, 42 yrs, 65 kg, 5'2" (157 cm), Moderate (household work + yoga):** BMR = 1,239 kcal। TDEE = 1239 × 1.55 = 1,920 kcal। Maintain 1,920 kcal, Cut 1,420 kcal (for safe weight loss), Bulk usually not goal। Common mistake — '1,200 calorie crash diet' (way below BMR) → metabolism slow, muscle loss, rebound weight gain। **5. Senior citizen, 65 yrs, male, retired, 72 kg, 5'7" (170 cm), Light activity:** BMR = (10 × 72) + (6.25 × 170) − (5 × 65) + 5 = 720 + 1062.5 − 325 + 5 = 1,463 kcal। TDEE = 1463 × 1.375 = 2,011 kcal। Maintain 2,011 kcal। Protein needs higher in seniors (1.0-1.2 g/kg minimum for muscle preservation) → 75-90g daily target। Resistance training 2-3×/week non-negotiable for healthy aging। ## Common mistakes **1. Crash diets — BMR se neeche calories khaana:** सबसे harmful mistake। 1,200-1,500 kcal crash diet (typical 'lose 10 kg in 30 days' plans) actually BMR से नीचे जाती है — body 'starvation mode' में जाती है: metabolism 15-30% slow, muscle break down (fat नहीं — energy preserve करने के लिए), nutritional deficiencies (iron, B12, calcium), period irregularities (women में), hair fall, mood swings। Sustainable rule — TDEE से max 500 kcal deficit, BMR के नीचे कभी नहीं। **2. Activity level over-estimate karna:** Most people खुद को 'moderately active' rate करते हैं but reality में sedentary होते हैं। Realistic check: अगर आप desk job करते हैं + सिर्फ weekend में gym जाते हैं + दिन में 5,000 steps से कम walk करते हैं — आप 'Sedentary' हो, 'Light' नहीं। Over-estimating activity = inflated TDEE = आप actual से ज़्यादा खा रहे हो = weight gain। **3. Protein under-estimate karna (Indian context):** Indian vegetarian diet typically protein-deficient होती है — typical Indian female 35-45g protein/day consume करती है, requirement 1.6-2.0 g/kg = 80-110g होनी चाहिए (especially weight loss में)। Result: muscle loss, weakness, slow metabolism, hair fall। Solution: हर meal में protein source (dal, paneer, tofu, eggs, yogurt, sprouts, whey) prioritize करो। **4. 'Calorie deficit alone weight loss karega' — exercise ignore karna:** Pure caloric deficit short-term weight loss देता है but mostly muscle loss + water loss। Sustainable fat loss के लिए: caloric deficit + strength training (muscle preserve) + cardio (heart health) + adequate protein (muscle protein synthesis) + 7-9 hours sleep (hormonal balance) — पूरा package। **5. Same calorie target forever rakhna:** Weight loss/gain के साथ TDEE change होती है। 80 kg से 70 kg हो गए — TDEE ~150-200 kcal कम हो जाएगी। Same calorie target रखने पर plateau आता है। हर 4-6 हफ्ते recalculate करो, target adjust करो। ## Pro tips Indian-specific protein recommendation higher है (1.6-2.0 g/kg body weight) क्योंकि traditional Indian diet rice/wheat-heavy, protein-deficient होती है — supplementation या conscious meal-planning ज़रूरी। Vegetarians के लिए: dal (cooked 1 cup = 18g protein), paneer (100g = 18g), tofu (100g = 8g), Greek yogurt (200g = 18g), sprouts (1 cup = 14g), eggs (1 = 6g if non-veg add करते हो)। Vegan options: soya chunks (50g dry = 26g protein!), peanut butter (2 tbsp = 8g), tempeh, seitan। Pre-workout 100-150 kcal carb (banana, dates) + post-workout 20-25g protein within 30 min (whey shake, paneer, eggs)। Hydration — 30-35 ml per kg body weight (70 kg person = 2.1-2.5L water/day, exercise day extra 500-750 ml)। Sleep 7-9 hours non-negotiable — sleep deprivation cortisol बढ़ाता है (abdominal fat), ghrelin बढ़ाता है (hunger hormone), leptin कम करता है (satiety hormone) — सब weight gain favor करते हैं। Stress management (yoga, meditation, journaling) chronic high cortisol कम करता है — visceral fat (पेट के अंदर organ-wrap fat, सबसे dangerous) reduce होता है। ## Modern context — 2026 mein kyon zaroori 2026 में India 'diabetes capital of the world' बना हुआ है — 100+ million diabetic adults, 136 million pre-diabetic। Heart disease #1 cause of death। दोनों conditions excess caloric intake + sedentary lifestyle से directly जुड़ी हैं। Urban Indian average daily caloric intake 2,400-2,800 kcal है (most के लिए actual TDEE 1,800-2,200 kcal — chronic 500-600 kcal surplus = annual 10-15 kg weight gain potential)। Food delivery apps (Swiggy, Zomato) ने accessible calories explosion कर दिया है — average pizza 1,200 kcal, biryani 1,400 kcal, chocolate cake slice 500 kcal — एक meal में पूरे दिन की calories। Fitness apps (HealthifyMe, Google Fit, Cult.fit) ने tracking democratize किया है but most users TDEE-aware नहीं हैं — generic '2000 kcal' goal use करते हैं। यह tool personalized accurate baseline देता है — आपकी specific body, specific activity के हिसाब से। Sustainable weight management की foundation। ## Health Disclaimer यह educational tool है — registered dietitian (RD) या certified nutritionist की advice की जगह नहीं ले सकता। PCOS, thyroid (hypo/hyper), diabetes (Type 1 या Type 2), pregnancy/lactation, eating disorders (anorexia, bulimia, binge eating), kidney disease, liver disease — किसी भी medical condition में doctor + dietitian से consult करें। Mifflin–St Jeor formula healthy adults (18-65 years) के लिए validated है — extreme low body weight (<40 kg), extreme high (>150 kg), या competitive athletes में clinical assessment ज़रूरी। Children + teens (under 18) के लिए pediatrician-recommended growth charts use करें। Elderly (65+) में slightly modified formulas exist — geriatric dietitian consult करें।

Formula / तरीका

Tips और सुझाव

• •BMR के नीचे कभी मत खाओ — crash diet metabolism slow करती है, muscle loss होती है, rebound gain होती है
• •Activity level honestly rate करो — desk job + weekend gym = Sedentary, Light नहीं (most लोग over-estimate करते हैं)
• •Indian protein needs higher — 1.6-2.0 g/kg body weight (Indian vegetarian diet typically protein-deficient होती है)
• •Vegetarian protein sources: dal, paneer, tofu, Greek yogurt, sprouts, whey; vegan: soya chunks (50g = 26g protein!), tempeh
• •Sleep 7-9 hours non-negotiable — sleep deprivation cortisol/ghrelin बढ़ाता है, leptin कम — सब weight gain favor
• •Hydration: 30-35 ml/kg body weight; exercise day +500-750 ml extra
• •हर 4-6 हफ्ते TDEE recalculate करो — weight change के साथ TDEE change होती है, plateau avoid करो
• •MANDATORY HEALTH DISCLAIMER: यह educational tool है — registered dietitian की advice की जगह नहीं ले सकता। PCOS, thyroid, diabetes, pregnancy, eating disorders में doctor + dietitian से consult करें।
