Ten days is enough to look noticeably less puffy and to start losing fat, but not enough to lose much of it. On a careful plan the scale usually falls by anything from under a kilo to about three. Only half a kilo or so of that is fat. The rest is water and stored carbohydrate that go first when sugar, rice and salt come down. Priya, 29, works at a bank branch in Hyderabad. Her cousin's wedding is ten days off, and the sangeet blouse stitched in March now pinches under the arms. The plan below is built around her. She is a composite of the readers who write to us, not a real patient.
The plan itself is short. From day one, drop sweet drinks and put 25–30 g of protein in every meal. Walk for 10–15 minutes after lunch and dinner, do three short strength sessions at home, and sleep seven hours. Weigh yourself only on days one, five and ten.
How much weight can you really lose in ten days?
Priya's bathroom scale will probably read a kilo or two lower by the wedding if she eats carefully, and a bit more if she started on a lot of rice and sugar. Only part of that is fat. The scale weighs fat, muscle, water, the contents of her gut and last night's salt all at once, and over ten days the water and the gut make up the bigger share.
Fat moves slowly. Kevin Hall's modelling in The Lancet showed that body weight settles into a calorie change over months, not days. That is why the old rule of a fixed number of calories per kilo overstates a short diet. For most adults, eating a few hundred calories less a day adds up to roughly half a kilo to a kilo of fat over ten days.
How much to trim depends on your size and your day. A 55 kg woman at a desk has far less room to cut than a 90 kg man on his feet at work. If you count calories, take off a modest slice of what you eat now rather than halving it, and let the protein and the walks carry the rest.

Why does the scale drop so fast in the first week?
Your liver and muscles keep a store of carbohydrate called glycogen, and each gram of it is held with three to four grams of water. Eat less rice, roti and sugar for a couple of days and the body dips into that store first. The water leaves with it, which is why many people see a kilo or more vanish by day three.
Kreitzman's work in the American Journal of Clinical Nutrition measured this in dieters, and it explains the reverse too. A heavy biryani dinner refills the store and pulls the water back. You can wake up a kilo heavier after a family function without having gained any fat.
Salt plays the same game. Restaurant food, papad and pickles make the body hold water for a day or two. Read the scale with that in mind, in both directions.

What does a 10-day weight loss plan look like?
Start on day one with drinks. Take the sugar out of your tea and coffee, and replace packaged juice, cold drinks and sweet lassi with water, plain buttermilk or black coffee. A glass of juice can carry as many calories as a roti and barely touches hunger, so this change costs you nothing in fullness.
From day one, also change the plate. Fill half of it with vegetables or salad, a quarter with dal, paneer, eggs, chicken or fish, and the last quarter with rice or roti. Walk for 10–15 minutes after lunch and after dinner. On days two, five and eight, do a short home session: three rounds of 10 squats, 10 wall push-ups and 10 lunges each side.
Weigh yourself on days one, five and ten, first thing in the morning after the toilet, before food. Daily readings swing by up to a kilo with salt, constipation and, for women, the menstrual cycle. A tape measure around the waist at the navel is often the more honest number for an event.
What should you eat over the ten days?
Protein does most of the work of keeping you full. Heather Leidy's review puts the useful range during weight loss at about 1.2–1.6 g of protein per kilo of body weight a day. It suggests 25–30 g at each main meal, which is more than most Indian breakfasts provide.
Here is what 25 g looks like in practice. Three eggs with a bowl of curd. Two besan chillas with a katori of curd. A big bowl of thick dal with a small katori of paneer. 100 g of chicken or fish. A cup of cooked soya chunks. Vegetarians usually need two sources at a meal to get there.
A workable day: three eggs with curd, or two chillas with curd, at breakfast. Dal, sabzi, salad and one roti or a small katori of rice at lunch. Buttermilk and a handful of roasted chana at five. Paneer or fish with vegetables by eight. Use a measured spoon of oil per dish rather than a pour. Protein at every meal is also what decides how much of the loss is fat rather than muscle. Metaboliq's doctors set a protein target first for that reason, in plans that aim to lose up to 20% of body weight while keeping muscle.

Which exercise helps most in ten days?
Walking after meals and three short strength sessions are enough for ten days. A ten-minute walk after dinner lowers the rise in blood sugar after that meal, helps digestion, and adds a little to the calorie gap without making you ravenous. The World Health Organization guidelines suggest 150–300 minutes of moderate activity a week, plus strength work on two days.
The strength sessions are there to protect muscle. When you eat less, the body will happily give up some muscle unless the muscles are being used. Squats, wall push-ups and lunges at home take 15 minutes. Skip any brand-new intense class in the week before a wedding; you want to be able to dance at the sangeet, not limp.

What can you change around the waist in ten days?
More than the scale suggests, because much of what a fitted blouse or kurta shows is not fat. A swollen gut, water held by salt and a few days of constipation can add a few centimetres at the navel. All three respond within a week, which is why the tape often moves faster than the fat does.
Salt is the quickest lever. Papad, pickle, namkeen, instant noodles and restaurant gravies make the body hold water for a day or two, so keep them for the wedding itself rather than the week before. Drink your usual water. Cutting it to look slimmer brings headaches and does nothing by the reception.
Constipation is the second. A sudden switch to salads and eggs can slow the gut for a few days. Keep dal, fruit, cooked vegetables and a bowl of curd in every day, and keep drinking your usual water. If gas is a problem, go easy on rajma, chole and raw onion in the last two days before the event.
Do crash diets and detox plans work faster?
They move the scale faster, mostly through water, and they make the days harder. Detox teas and slimming drinks often act as laxatives or diuretics. What leaves is fluid, and it is back within days of stopping.
A trial in Melbourne led by Katrina Purcell compared fast dieting over 12 weeks with slow dieting over 36 weeks in 200 adults. Nearly three years on, both groups had regained about 71% of what they lost, so speed did not decide the outcome. One person in the fast group developed an inflamed gallbladder that needed surgery.
That trial was supervised and ran for months, so it does not make a ten-day starvation diet safe. Very low intake before an event mainly gives you headaches, dizziness and a short temper, and a binge at the mehendi is the usual end of it.

Why does sleep change how much fat you lose?
Arlet Nedeltcheva's team at the University of Chicago put ten adults on the same reduced-calorie diet for two weeks, twice. Once they had eight and a half hours in bed each night, and once five and a half. On short sleep, the fat they lost fell by more than half, and the lean tissue they lost rose by 60%.
Ten people is a tiny study, and it would not settle the question on its own. But anyone who has done a late shift knows the pattern. After a short night you are hungrier, the fried snacks at the office pull harder, and the evening walk is the first thing dropped. Wedding weeks run on late nights and early fittings, so protect the nights in between: phone down by eleven, and the same alarm every morning.

What happens after day ten?
On day eleven, change one thing: stop weighing every morning and switch to once a week, same day, same time. Keep the plate, the walk after dinner and two strength sessions a week. If the wedding food has been heavy, go back to the day-one drinks rule for a few days rather than skipping meals.
Expect the scale to slow down, and do not read that as failure. The water went in the first few days, so what is left is fat coming off at its real pace, often a few hundred grams a week. Jessica Unick's analysis of the Look AHEAD trial followed thousands of adults for eight years. People who lost more in the first one or two months were more likely to still be lighter at the end, so a good first fortnight is worth building on.
Has the weight crept back after every short plan so far? Then it is worth finding out why. A doctor-led plan starts with a home blood test and a doctor's review, which shows whether sugar, insulin or thyroid problems are making this harder than it should be.
