TDEE and Macro Calculator: What to Eat, Not Just How Much

• TDEE (Total Daily Energy Expenditure) tells you how many calories to eat. Macros tell you how to split those calories into protein, carbohydrates, and fat — which determines whether you lose fat or muscle.
• Protein is the most important macro to get right. Most people eat 40–60g/day; optimal for muscle preservation during fat loss is 1.6–2.2g per kg of bodyweight.
• Carbs and fat are flexible — you can adjust the split based on preference. The evidence for extreme low-carb or low-fat diets is weaker than adherence to any reasonable split with adequate protein.
• "Tracking macros" is not about perfection — getting within 10g of your targets daily is sufficient for meaningful results.

Use our free TDEE and Macro Calculator to find your total daily calorie need and personalised protein, carb, and fat targets — for fat loss, muscle gain, or maintenance.

TDEE: Your Starting Number

TDEE (Total Daily Energy Expenditure) is the total calories your body burns in a day — including BMR (at-rest metabolism), activity, exercise, and food digestion.

Quick TDEE calculation:

1. Calculate BMR using Mifflin-St Jeor: - Men: (10 × kg) + (6.25 × cm) − (5 × age) + 5 - Women: (10 × kg) + (6.25 × cm) − (5 × age) − 161

2. Multiply by activity factor: - Sedentary (desk job, no exercise): × 1.2 - Lightly active (1–3 days exercise/week): × 1.375 - Moderately active (3–5 days/week): × 1.55 - Very active (6–7 days/week hard exercise): × 1.725 - Extremely active (physical job + training): × 1.9

Example — 28-year-old man, 80 kg, 178 cm, moderately active: BMR = (10 × 80) + (6.25 × 178) − (5 × 28) + 5 = 800 + 1,112.5 − 140 + 5 = 1,777.5 kcal TDEE = 1,777.5 × 1.55 = 2,755 kcal/day

This man burns ~2,755 calories daily. Eating 2,255 kcal (500 deficit) targets ~0.5 kg fat loss per week. Eating 2,755 kcal maintains current weight.

What Are Macros and Why Do They Matter?

Macronutrients are the three categories of nutrients that provide energy:

Macro	Calories per gram	Primary role
Protein	4 kcal	Muscle repair, satiety, immune function
Carbohydrates	4 kcal	Primary energy source, brain fuel
Fat	9 kcal	Hormones, cell membranes, fat-soluble vitamins

All three provide energy. All three are required for health. The question is: in what ratio?

The answer depends on your goal, preferences, and individual response. But protein requirements are non-negotiable — carb and fat ratios are flexible.

Protein: The Non-Negotiable Macro

Why protein requirements are the most evidence-based aspect of macro setting:

During a calorie deficit (fat loss phase), the body can break down both fat AND muscle for energy. The ratio depends heavily on protein intake. Adequate protein intake:

• Signals the body to preserve muscle tissue
• Provides the amino acids for muscle protein synthesis
• Is more satiating per calorie than carbs or fat (reduces hunger)
• Burns more calories digesting (20–30% thermic effect vs. 5–10% for carbs)

Evidence-based protein targets:

Goal	Protein Target
Minimum for health	0.8g per kg bodyweight
Fat loss (muscle preservation)	1.6–2.2g per kg bodyweight
Muscle gain	1.6–2.0g per kg bodyweight
Athletic performance	1.8–2.5g per kg bodyweight
60+ years (sarcopenia prevention)	1.2–1.6g per kg bodyweight

For the 80 kg man in our example (fat loss goal): Protein target: 80 × 1.8g = 144g protein/day Protein calories: 144 × 4 = 576 kcal

This leaves 2,255 − 576 = 1,679 kcal for carbs and fat.

Indian diet protein reality check:

The average Indian diet is chronically low in protein — particularly for vegetarians. ICMR recommends 0.8g/kg/day, but most Indians get 40–55g/day regardless of bodyweight.

Common Indian protein sources (per 100g unless noted):

Food	Protein (g)	Notes
Chicken breast (cooked)	31g	Most efficient animal protein
Paneer	18g	Best vegetarian dairy option
Dal (cooked)	9g	Legumes provide ~9g/100g cooked
Moong sprouts	3.0g per 100g	Lower than often claimed
Eggs (1 large)	6g	Complete protein
Greek yogurt / hung curd	10–17g	Good snack protein
Tofu	8g	Plant-based complete protein
Whey protein (1 scoop)	20–25g	Most efficient protein supplement
Rajma (cooked)	8.7g	Complete amino acid profile

A 60kg vegetarian woman targeting 1.8g/kg/day needs 108g protein/day. That requires conscious dietary effort — not achievable through typical Indian vegetarian meals without supplementation or significant food tracking.

Setting Carbohydrate and Fat Targets

Once protein is set, the remaining calories split between carbs and fat. The split is genuinely flexible — research doesn't show one ratio to be consistently superior for fat loss when protein is controlled.

Common macro splits:

Approach	Protein	Carbs	Fat	Best For
Balanced	30%	40%	30%	Most people, general health
Higher carb	25%	50%	25%	Endurance athletes, heavy training
Lower carb	35%	25%	40%	Insulin resistance, PCOS, some prefer it
Ketogenic	25%	<5%	70%+	Specific medical/preference; not superior for most

How to calculate carbs and fat from remaining calories:

Using our 80 kg man example:

• Total calories for fat loss: 2,255 kcal
• Protein calories: 576 kcal (144g)
• Remaining: 1,679 kcal → split 50% carbs, 50% fat

Carb calories: 839 kcal ÷ 4 = 210g carbs/day Fat calories: 839 kcal ÷ 9 = 93g fat/day

Final macro targets: 144g protein / 210g carbs / 93g fat / 2,255 kcal

Adjusting Macros for Specific Goals

Fat Loss

• Set 300–500 kcal deficit from TDEE
• Protein: 1.8–2.2g/kg (prioritise — higher end if strength training)
• Fat: minimum 0.5–0.6g/kg (essential for hormones — don't go below this)
• Carbs: remaining calories
• Fibre: 25–35g/day (reduces hunger, improves digestion)

Muscle Gain (Lean Bulk)

• Set 200–300 kcal surplus above TDEE
• Protein: 1.6–2.0g/kg (higher doesn't add more muscle — diminishing returns above 2.0g/kg)
• Carbs: higher (fuels training, promotes glycogen storage and muscle recovery)
• Fat: moderate (0.8–1.0g/kg)
• Surplus too large = fat gain accelerates without proportional muscle gain

Maintenance / Recomposition

• Calories: at TDEE
• Protein: 1.6–2.0g/kg
• Carbs and fat: personal preference
• Body recomposition (simultaneous fat loss + muscle gain) is possible in beginners and returning trainees at maintenance calories with high protein and strength training

The Indian Vegetarian Macro Challenge

Getting adequate protein on a vegetarian Indian diet requires specific strategies:

Protein-first meal planning:

Breakfast option: 200g hung curd + 2 eggs + 30g oats = ~34g protein Lunch option: 150g paneer + 1 cup dal + 2 chapati = ~42g protein Dinner option: 100g tofu + rajma sabzi (100g) + 1 cup curd = ~30g protein Snack: 1 scoop whey + 200ml milk = ~30g protein

Total: ~136g protein — achievable but requires deliberate planning.

For those who can't use whey protein: Greek yogurt (hung curd), paneer at multiple meals, and legume combinations at every meal are the highest-leverage vegetarian strategies.

Tracking Macros: How Precise Do You Need to Be?

Research shows that being within 10% of your protein target and within 10–15% of your calorie target produces meaningful, consistent results. You don't need to be exact.

Practical tracking approach:

• Use an app (MyFitnessPal, HealthifyMe, Cronometer) for the first 4–6 weeks to build intuitive understanding
• Weigh food raw on a kitchen scale for the first 2–3 weeks — portion size estimation is reliably inaccurate until calibrated
• After the learning phase, most people can maintain targets without constant tracking

What to prioritise when tracking is difficult: 1. Hit protein target (most important) 2. Stay within calorie range (second most important) 3. Let carbs and fat self-regulate within the calorie budget

Macro perfection without calorie awareness misses the point. Calorie awareness without protein attention loses muscle. Both matter — protein is the tiebreaker.

FAQ

What is the difference between TDEE and BMR?

BMR (Basal Metabolic Rate) is the calories you burn at complete rest. TDEE (Total Daily Energy Expenditure) includes BMR plus all your daily activity, exercise, and food digestion. TDEE is always higher than BMR and is the number you use to set calorie targets.

How much protein do I need per day?

For fat loss with muscle preservation: 1.6–2.2g per kg of bodyweight. A 70 kg person needs 112–154g protein/day. This is significantly higher than general health recommendations (0.8g/kg) and requires conscious planning — especially on vegetarian Indian diets.

Is low carb better than balanced macros for weight loss?

When protein is controlled, fat loss on low-carb and balanced-carb diets is statistically similar in controlled studies. Low-carb tends to produce faster initial loss (mostly water and glycogen), which can be motivating. Long-term adherence matters more than which split you choose.

How do I calculate my macros?

Step 1: Calculate TDEE (BMR × activity multiplier). Step 2: Set calorie target (TDEE minus 300–500 for fat loss). Step 3: Set protein at 1.6–2.2g/kg bodyweight. Step 4: Set fat minimum at 0.5–0.6g/kg. Step 5: fill remaining calories with carbs.

Do I need to track macros forever?

No. Most people benefit from 4–8 weeks of active tracking to build intuitive portion and food density knowledge. After that, periodic check-ins (1–2 weeks every few months) maintain calibration without daily tracking burden.

Macros Make Calories Purposeful

Knowing your TDEE tells you how much to eat. Knowing your macros tells you how to structure that eating so the weight you lose is fat, not muscle — and so you have the energy and recovery to train, perform, and feel well throughout the process.

Start with protein. Everything else adjusts around it.
