An intermittent fasting Indian diet plan simply moves your usual meals into a fixed window, for example eating from 10 am to 6 pm (16:8) or from 9 am to 7 pm (14:10), and drinking only water, black coffee or plain tea outside it. What you eat inside the window still decides the result, because the research shows time-restricted eating works mostly by helping people eat less.
What do 16:8 and 14:10 mean?
The first number is the hours you fast, the second the hours you eat. On 16:8 you fast for 16 hours and eat within 8. On 14:10 you fast for 14 hours and eat within 10, which is a gentler place to start.
Here is how that looks with common Indian routines:
| Plan | Eating window | Fasting hours | Fits people who |
|---|---|---|---|
| 14:10 | 9 am to 7 pm | 7 pm to 9 am | Eat an early dinner and like a proper breakfast |
| 16:8 | 10 am to 6 pm | 6 pm to 10 am | Can shift breakfast to mid-morning and finish dinner early |
| 16:8 (late) | 12 noon to 8 pm | 8 pm to 12 noon | Eat dinner with family at 8 pm and can skip morning chai |
The hardest part for most Indian households is the evening. If dinner is usually at 9 or 10 pm, pick a later window rather than eating dinner alone at 6. The intermittent fasting calculator works out start and end times for any plan.
What breaks a fast, and does chai count?
Strictly, anything with calories ends the fast. Chai with milk and sugar does: one cup made with 75 ml of cow’s milk and 2 tsp of sugar is about 85 kcal. The same goes for juice, coconut water, biscuits and a handful of nuts.
These are fine during the fasting hours:
- Water, plain or sparkling
- Black coffee and plain black or green tea with no milk or sugar (USDA lists brewed coffee and tea at about 1 kcal per 100 ml)
- Lemon water without honey or sugar (half a lemon adds roughly 5 kcal)
If you cannot give up morning chai, have it as the first thing inside your window rather than at 6 am.

Neither day is a target for you. They show how ordinary meals fit a window. Scale portions up or down to match your own number, and see the idli page for other idli sizes.
How we estimated these numbers: home cooking, weighed raw. Atta, besan, dals, raw rice, paneer, milk, coconut, vegetables and fruit use IFCT 2017. Cooked rice, curd, chickpeas, eggs, sambar, oil, ghee and sugar use USDA FoodData Central. 1 tsp of oil or ghee is 5 g, milk in ml is counted as grams, and each item is rounded to the nearest 5 kcal and 0.5 g protein before adding up.
How many calories should you eat per day while intermittent fasting?
The same number you would eat without fasting. Your energy needs come from your body size and activity, not from the clock. Start with your maintenance and a 250 to 500 kcal deficit from the calorie deficit calculator, then split those calories across two or three meals in your window.
For reference, the largest 12 month trial below asked women to eat 1,200 to 1,500 kcal and men 1,500 to 1,800 kcal a day, with or without a time window.
Does intermittent fasting work better than just eating less?
Mostly, no. The good trials suggest a window helps because it makes eating less easier, not because fasting hours burn fat on their own:
- Liu et al., NEJM 2022: 139 adults with obesity in China, all on the same calorie-restricted diet for 12 months. The group eating only between 8 am and 4 pm lost 8.0 kg; the group eating at any time lost 6.3 kg. The difference was not statistically significant.
- Lowe et al., JAMA Internal Medicine 2020: 116 adults, 12 weeks of 16:8 (noon to 8 pm) without other changes. They lost 0.94 kg against 0.68 kg for people eating three regular meals, again not a significant difference. In the smaller in-person group, the fasting group also lost more lean mass from the arms and legs.
- Lin et al., Annals of Internal Medicine 2023: 90 adults with obesity, 12 months. Eating from noon to 8 pm without counting cut intake by about 425 kcal a day, close to the 405 kcal cut in the calorie-counting group, and weight loss was similar in both.
- Jamshed et al., JAMA Internal Medicine 2022: 90 adults, 14 weeks, all on a calorie-reduced plan. Eating from 7 am to 3 pm led to 2.3 kg more weight loss than a 12 hour or longer window, which the authors said was equal to eating about 214 kcal less a day. Body fat loss was not significantly different.
So treat a fasting window as a tool for eating less. If it makes your day simpler, use it. If it leads to overeating at the first meal, a normal three-meal deficit works just as well.
Who should not try intermittent fasting?
Do not start intermittent fasting without speaking to a doctor or registered dietitian if you:
- are pregnant or breastfeeding
- are under 18
- have diabetes and take insulin or other medicines that lower blood sugar, or have had low blood sugar episodes
- have, or have had, an eating disorder
- are underweight, or live with kidney disease, PCOS or another long-term condition
Whatever window you choose, do not let total intake fall below 1,200 kcal a day.
The practical takeaway
Start with 14:10 for two weeks, keep your meals the same, and only then try 16:8 if it feels easy. Have chai inside the window, keep water and black tea or coffee for the fasting hours, and judge success by your weekly average weight and how well you stick to it. The Calo AI app has a free fasting timer with plans from 12:12 to 20:4 if you want reminders, but a phone alarm does the same job.
