A 75 kg woman of average height usually burns about 1,800–2,000 calories a day. Eating around 1,400 calories, with 60–75 g of protein spread across three meals, gives a steady deficit without hunger taking over. On Indian food, that means one katori of rice or two rotis per meal, measured oil, no sugar in tea, and dal, paneer, eggs, curd or chicken on every plate. Add a daily walk and two strength sessions a week to protect muscle.
On a steady 500-calorie cut, the first 10 kg usually takes closer to a year than a few months. Loss is fastest in the first weeks and slows as you get lighter. Daily walking and strength work speed it up and help keep the loss as fat. Your own calorie target depends on your height, age and how much you move.
How many calories should a 75 kg woman eat to lose weight?
Start with your own numbers, because 75 kg means different things at 150 cm and at 170 cm. Take Sunita, 36, a schoolteacher in Jaipur who is 158 cm tall and weighs 75 kg. Sunita is an illustration, not a patient, so swap in your own figures as you read. The Mifflin–St Jeor equation, the one most calculators use, gives her resting burn as 10 × 75 + 6.25 × 158 − 5 × 36 − 161. That works out to about 1,400 calories a day.
Next comes activity. Sunita stands to teach but drives to school and sits in the evenings. Guidelines often multiply by 1.5 or more for someone like her, but when Sinha, Kurpad and Kuriyan measured 19 young men in Bengaluru, their real ratio was about 1.35. Daily burn came out roughly 13% below the guideline figure. That study had no women in it, so treat 1.35 as a cautious guess for Sunita, not a measured number. At 1.35, she would burn around 1,900 calories a day.
The American obesity guideline suggests a deficit of 500–750 calories, which for most women lands at 1,200–1,500 calories a day. For Sunita, 1,400 is a sensible target: enough food to feel normal, low enough to lose steadily. A shorter or less active woman at 75 kg might need 1,300. A taller woman who walks a lot can eat 1,500 or more and still lose.
What does a 1,400-calorie Indian diet plan look like?
Here is one vegetarian day for Sunita. On waking: water, and tea with toned milk and no sugar. Breakfast at 8.30: two moong dal chillas with mint chutney and a small bowl of curd, about 300 calories and 18 g of protein. Mid-morning: one apple or guava.
Lunch at 1: one katori of rice or two thin rotis, and one katori of thick dal. Add a katori of lauki or bhindi sabzi made with one teaspoon of oil, and a plate of cucumber and tomato. That comes to roughly 450 calories and 18 g of protein. At 5 pm: tea without sugar and a handful of roasted chana, about 150 calories.
Dinner at 8: 100 g of paneer bhurji or tofu with capsicum, one roti and a bowl of mixed vegetable soup or palak. That is about 400 calories and 22 g of protein. Counting the fruit and the milk in two cups of tea, the day comes to about 1,400 calories and 65 g of protein, cooked with about four teaspoons of oil in all.
Nothing here needs special food. Keep a festival or wedding meal as a planned exception once a week, and go back to the plan at the next meal.
How can you vary the plan across a week?
Keep the structure fixed and rotate the dishes. Each meal has the same three parts: a protein anchor, a measured grain and plenty of vegetables cooked in little oil. In this plan a katori means a 150 ml bowl, a thin roti uses about 30 g of atta, and a handful of roasted chana is about 30 g.
Breakfasts to rotate, each around 250–300 calories: moong dal chilla with curd, or two eggs with one roti. Vegetable poha with a tablespoon of peanuts and a bowl of curd works too. So do vegetable upma with sprouts, ragi dosa with sambar, or besan chilla stuffed with paneer.
Lunches to rotate: dal with rice or rotis, or rajma or chole with one katori of rice. Kadhi with jeera rice and a dry sabzi is another. Sambar with two idlis and a vegetable poriyal suits South Indian kitchens, and curd rice with a large salad and roasted chana is good on hot days. Keep the grain to one katori or two rotis, whatever the dish.
Dinners to rotate: paneer bhurji with one roti, or soya chunk curry with palak. Grilled fish or chicken with sautéed vegetables works for non-vegetarians. Moong dal khichdi with curd, or a large bowl of dal soup with a vegetable stir-fry, is lighter. Sunday can be the family meal of your choice, eaten from a smaller plate.
How much protein does a woman losing 10 kg need?
Usually more than a vegetarian Indian day provides. A typical day of poha, dal-chawal, a biscuit with tea and roti-sabzi can easily come in under 50 g of protein. During a calorie cut, a practical target for most women is 60–75 g, spread across three meals rather than loaded into dinner. Women over 50 or doing regular strength training may do better with a little more.
The evidence for this is consistent. Thomas Wycherley's meta-analysis pooled 24 trials in which people ate the same number of calories, but some ate more protein. The higher-protein groups lost a little more fat and kept more of their lean mass, the muscle and organ tissue that keeps your metabolism up. They also reported feeling fuller in most of the studies that asked.
In practice, build each meal around one protein food. Two eggs or a besan chilla at breakfast. A full katori of thick dal, rajma or chole at lunch with a bowl of curd. Paneer, tofu, soya chunks, chicken or fish at dinner. A glass of milk or a small serving of roasted chana fills the gap in the afternoon.

What changes for non-vegetarians and busy days?
Non-vegetarian women have an easier time reaching protein. Swap the chillas for two boiled eggs and a slice of whole wheat toast. At dinner, 120 g of grilled or tandoori chicken, or a fish curry made with a teaspoon of oil, replaces the paneer for fewer calories and more protein. Firm tofu has less protein than paneer, so take about 150 g in its place. Keep fried fish, butter chicken and biryani for occasions.
On office days, a steel dabba with two rotis, a dry sabzi and a separate box of dal or chole works better than canteen food. If lunch has to be bought, choose a thali and leave half the rice, or order a plain dosa with sambar rather than a masala dosa. Sprouts chaat, buttermilk and a fruit are easy to carry for the afternoon.
Late meetings make dinner the hardest meal to control. Eat something with protein at 5 pm, so that you are not ravenous when you finally reach the table at nine.
How long does it take to drop 10 kg from 75 kg?
Longer than most diet charts promise. The old rule says a 500-calorie daily deficit takes off half a kilo a week, which would put 10 kg about 20 weeks away. Diana Thomas and colleagues compared that rule against carefully supervised experiments and found it consistently overestimated real weight loss.
The reason is that the body adjusts. As you get lighter you burn less, so the same 1,400 calories becomes a smaller deficit each month. Kevin Hall's modelling at the US National Institutes of Health shows weight change following a curve: faster at first, then slower, with about half the eventual loss arriving in the first year.
If Sunita eats a fixed 1,400 calories while her needs slowly fall, that model points to roughly 10 kg over about a year. It is an average, and real people vary on either side of it. The first weeks move fastest, partly from water, and the last kilos come slowest. Adding a daily walk and strength work widens the gap and shortens the wait. That is slower than the charts on social media promise, but it is the pace at which weight tends to stay off, because habits and muscle have time to keep up.
Is low-carb or low-fat better for a 75 kg woman?
Neither wins on its own. In Christopher Gardner's DIETFITS trial at Stanford, 609 adults were randomly assigned to a healthy low-fat diet or a healthy low-carbohydrate diet for a year. Both groups were told to eat whole foods and cut sugar and refined flour. After 12 months they had lost similar amounts of weight. Genes and insulin levels did not predict who would do better on which plan.
For Indian women this is useful, because a strict low-carb plan cuts across almost every family meal. Halving the rice, choosing whole wheat or jowar rotis and dropping sugar and maida gets most of the benefit. Women with PCOS or high fasting insulin may feel steadier with fewer carbohydrates. A doctor can tell from the blood tests whether that applies.
Pick the version of the 1,400-calorie day above that fits your kitchen, including on a tired weeknight when the family wants parathas, and stay with it.

How do you keep muscle while losing 10 kg?
Eating less on its own takes some muscle along with the fat. A review of 52 studies by Wayne Campbell's group at Purdue showed how much. In 81% of the groups that only dieted, at least 15% of the weight lost was fat-free mass. In groups that also exercised, the figure fell to 39%.
The World Health Organization advises 150–300 minutes of moderate activity a week plus strength work on at least two days. For Sunita that could mean a 30-minute brisk walk after dinner five days a week and two 20-minute sessions at home. Squats to a chair, wall push-ups, lunges holding two filled water bottles and a plank cover the big muscles. When those feel easy, a resistance band from the local sports shop adds load for very little money.
Holding on to muscle also keeps bigger goals open. For some women at 75 kg the first 10 kg is where they want to stop, and for others it is a start. With a doctor-led plan, a woman can lose up to 20% of her body weight and keep her muscle. That kind of plan begins with a home blood test for thyroid, sugar, insulin and vitamins, so that anything slowing her down is found before the target is set.
What should you do if the scale stops moving?
Expect it. Stalls of two or three weeks are common. Water shifts around periods, salty meals and constipation can hide fat loss for a fortnight. Weigh three mornings a week and compare weekly averages before changing anything.
If the average is flat for three weeks, check the leaks first. Measure the oil again, count the chai, and look at weekends, which often undo two weekdays of careful eating. If the leaks are plugged and you are eating enough protein, add a 15-minute walk after lunch or trim 100–150 calories, but not below about 1,200. As you get lighter, you genuinely need a little less food.
Measure your waist once a month at the navel too. If the waist is shrinking while the scale stands still, you are probably losing fat and holding on to muscle, which is exactly what you want.
