Calorie deficit explained: how to lose fat on an Indian diet

What a calorie deficit actually is

Your body burns energy every day to keep your heart beating, digest food, move around and train. That total is your TDEE (Total Daily Energy Expenditure). Eat less than it and your body makes up the difference from stored energy — mostly fat, if you are training and eating enough protein.

A deficit is not a punishment. It is a small, temporary gap. Most people do best at 15–20% below maintenance, which usually means 300–500 kcal per day and roughly 0.4–0.7 kg of fat loss per week.

Finding your starting number

Estimate your TDEE with a calculator, then treat the result as a hypothesis rather than a fact. Eat at that number for two weeks, weigh yourself each morning under the same conditions, and take the weekly average. If the average is flat, that is your true maintenance. Subtract 400 kcal and begin.

• Sedentary desk job: bodyweight (kg) × 28–30 kcal is a fair maintenance estimate
• Training 3–4 times a week: bodyweight × 32–34 kcal
• Physically active job plus training: bodyweight × 36–38 kcal
• Deficit target: subtract 300–500 kcal from that number

Making the Indian plate work

The Indian thali is not the problem — the invisible calories in it are. Oil, ghee, sugar in chai, and second helpings of rice contribute far more than most people estimate, while protein tends to be under-represented.

You do not have to remove anything. Shift the ratios: fill half the plate with vegetables and salad, a quarter with a protein source (dal, paneer, curd, eggs, chicken, soya), and a quarter with your carbohydrate of choice. Measure cooking oil with a spoon rather than pouring, and drink your chai with less sugar rather than none, so the change survives past week three.

• 1 tbsp oil = about 120 kcal — a family curry can easily hide 400 kcal of it
• 1 katori rice = about 130 kcal, 1 roti = about 100 kcal
• 2 sugary chais a day = roughly 200 kcal, or 1.5 kg of fat over three months
• Adding 30 g of protein at breakfast typically reduces evening snacking without effort

Why the scale lies for days at a time

Water retention from salt, carbohydrate intake, sleep debt, travel and the menstrual cycle can swing bodyweight by 1–2 kg in either direction. That is noise, not fat. Judge progress on the weekly average and on measurements taken every fortnight, not on any single morning.

If the weekly average has not moved in three consecutive weeks and you have been consistent, reduce intake by another 150–200 kcal or add 2,000 daily steps. Do not do both at once — you want to keep something in reserve.

Protecting muscle while you lose fat

A deficit tells your body to shed tissue; strength training and protein tell it which tissue to keep. Aim for 1.6–2.2 g of protein per kilogram of bodyweight and lift two to four times a week. Without these, up to a quarter of the weight you lose can come from muscle, which lowers your maintenance calories and makes the next attempt harder.
