Diabetes in the Festive Season: Managing Blood Sugar From Durga Puja to Diwali

None of this has to be given up. But it does need a plan, because the festive season is where blood sugar control often slips, and the cost appears months later on an HbA1c report. This guide lays out what works, what does not, and when a doctor needs to be involved.

Can diabetics eat sweets during Diwali and Durga Puja?

Yes, most people with diabetes can eat a small amount of sweets during festivals, provided it is planned. Diabetes is common enough that nearly every extended family is managing this question. The ICMR-INDIAB-17 national survey, published in The Lancet Diabetes and Endocrinology in 2023, examined 113,043 adults and found diabetes in 11.4 per cent and prediabetes in another 15.3 per cent. The practical rule is portion and timing rather than prohibition: one piece of a sweet, eaten at the end of a meal, with a matching reduction in rice or roti, is very different from three pieces eaten as an afternoon snack. Blanket bans tend to fail by Ashtami and end in a larger lapse.

Why blood sugar drifts up between Puja and Diwali

Several things change at once. Sweets and fried snacks arrive daily rather than occasionally. Meal times move late into the night, which disrupts the timing of tablets and insulin. Sleep shortens, and short sleep makes glucose harder to control the next day. Daily walks and routines are dropped for visits and pandal hopping. Stress and travel play a part too. And because October often brings viral fevers and dengue, an infection can push readings up for reasons that have nothing to do with food. HbA1c reflects average blood sugar across roughly the previous two to three months, so the effect of the season usually shows in the first test of the new year.

What blood sugar numbers should you aim for during festivals?

The same targets your doctor has already set, which for many adults follow the American Diabetes Association's general range of 80 to 130 mg/dL before meals and under 180 mg/dL one to two hours after eating. Older adults, people prone to low sugar and pregnant women often have different targets, so the personal numbers from your own doctor come first. Festivals are not the time to stop checking. A glucometer reading two hours after a heavy bhog lunch or a Diwali dinner shows exactly how your body handled that particular meal, which is far more useful than any general list of good and bad foods. Note down any unusual readings to discuss at your next review.

Which Indian sweets are least harmful for diabetics?

None is harmless, but smaller, less fried and less syrupy sweets do the least damage per piece. Chhena sweets like sandesh are a reasonable choice, with a small piece of about 30 g at roughly 80 to 120 kcal. A rasgulla is roughly 100 to 140 kcal, and squeezing out the syrup removes some of the sugar. A piece of kaju katli is roughly 55 to 75 kcal but is almost entirely sugar and cashew. Fried, syrup-soaked sweets are the heaviest: a gulab jamun is roughly 140 to 180 kcal and a medium jalebi about 150. The calories in Indian sweets page has more figures. Size and number matter more than which sweet you choose.

Are sugar-free sweets a safe swap?

Only partly, and many people eat more of them because of the label. Sugar-free mithai replaces sugar with sweeteners, but the khoya, ghee, nuts and flour remain, so the calories and fat can be close to the original. Some products use sugar alcohols such as maltitol, which raise blood sugar a little and can cause loose motions in larger amounts. Others still contain dried fruit or jaggery. A sugar-free sweet eaten in the same small portion as a regular one is a modest improvement; a whole box because it says sugar-free is not. The post on sugar-free sweets for diabetics compares what is actually inside these products.

Does the order you eat food in change blood sugar?

Yes, and the effect can be substantial, although the best-known evidence comes from a small study. In a 2015 pilot study published in Diabetes Care, 11 adults with type 2 diabetes ate the same meal on two occasions. When they ate the vegetables and protein first and the carbohydrate 15 minutes later, their blood glucose after the meal was lower by 28.6 per cent at 30 minutes, 36.7 per cent at 60 minutes and 16.8 per cent at 120 minutes, compared with eating the carbohydrate first. At a festive meal, that means starting with labra, dal, fish, paneer or salad, then rice or luchi, and eating the sweet last.

Does walking after a festive meal help blood sugar?

Yes, and the timing matters more than the length of the walk. A 2016 randomised crossover study in Diabetologia compared two ways of walking for 41 adults with type 2 diabetes: 10 minutes after each main meal, or one 30-minute walk at a single time of day. Walking after meals lowered the rise in blood sugar after eating by 12 per cent overall, and by 22 per cent after the evening meal, which carried the most carbohydrate. During festivals, a slow 10-minute walk after a bhog lunch or a Diwali dinner, even round the pandal or the building, is one of the simplest tools available and suits most people.

Can you fast on Ashtami or Karva Chauth with diabetes?

Some people with well-controlled diabetes can, but anyone taking insulin or sulfonylurea tablets must ask their doctor before fasting. These medicines keep lowering blood sugar even when no food arrives, so a long fast can cause dangerous hypoglycaemia. International guidelines on religious fasting with diabetes, such as the 2017 IDF-DAR practical guidelines written for Ramadan, sort people into risk groups and recommend a medical review before any fast, with medication timing and doses adjusted by the treating doctor. The same thinking applies to Navratri, Ashtami and Karva Chauth. The dedicated guide on fasting with diabetes during Navratri and Karva Chauth explains how to plan the conversation.

Planning a bhog plate or a Diwali thali with diabetes

The plate needs the same structure whether it is Ashtami bhog or a Diwali dinner. Fill half of it with vegetables such as labra, a dry sabzi or salad. Keep a quarter for protein: dal, fish, chicken, egg, paneer or chana. Limit the last quarter to starch, which means one katori of khichuri or rice, or two small rotis or luchis rather than six. The sweet then replaces part of that starch rather than being added on top. The American Diabetes Association's 2019 consensus report on nutrition therapy found no single ideal split of carbohydrate, protein and fat for everyone, which is why the plate method adapts so easily to Bengali, Punjabi and South Indian festive food.

Alcohol, late nights and Kali Puja parties

Alcohol at Diwali and Kali Puja parties carries a specific risk for people on insulin or sulfonylureas. The liver releases stored glucose to keep blood sugar up between meals, and alcohol interferes with that process, so blood sugar can fall several hours after drinking, often during the night. Beer and sweet mixers add carbohydrate at the same time, which makes readings harder to predict. If you drink, do it with food, keep to a small amount, avoid sugary mixers, and check your sugar before bed. Let someone at the party know that you have diabetes. Late dinners also shift the timing of medicines, so ask your doctor how to handle that before the season starts.

What to do if your sugar goes low at a celebration?

Treat it at once with a fast-acting sugar, then recheck. Low blood sugar, generally below 70 mg/dL, can feel like shakiness, sweating, a racing heart, confusion or sudden hunger, and in a noisy, crowded party it is easily mistaken for tiredness. Take about 15 g of fast carbohydrate, such as three teaspoons of sugar dissolved in water, glucose tablets or half a glass of regular fruit juice, and check again after 15 minutes, repeating if still low. Mithai is a poor choice, because the fat in it slows the sugar down. If the person is drowsy, confused or unconscious, do not put food in their mouth; call emergency help immediately.

What if sugar runs high for several days?

Contact your doctor if readings stay above your targets for more than a day or two, and seek help the same day if they run above about 250 mg/dL with vomiting, heavy thirst, drowsiness or fever. A few high readings after a festive meal are common and usually settle with a return to routine. Persistent high numbers are different. They may point to missed medication, an infection, dehydration or a dose that no longer fits. People with type 1 diabetes should also check for ketones as their care team has advised. October's fevers deserve particular attention, and the dengue diet chart covers eating during an illness that also affects sugar control.

Supporting a parent with diabetes through the festivals

Much festive diabetes care happens in the family, not the clinic. Older parents often feel watched and restricted during celebrations, which makes secret eating more likely. It helps to plan with them rather than police them: agree in advance on one sweet a day, cut sweets into small pieces, and serve them after meals. Keep dinner timings as close to normal as possible, or ask the doctor how to adjust medicines when dinner will be late. Make sure someone in the house recognises the signs of low sugar, because older adults may not feel the warning symptoms. And offer good food rather than only restrictions: a well-made diabetes-friendly Indian diet still has plenty to celebrate with.

Where diabetes education becomes a profession

Everything in this guide, from plate planning to explaining food order, walking after meals and when to call a doctor, is the daily work of a diabetes educator or nutritionist. It needs clinical understanding and a practical sense of how Indian families actually eat. NNWA's Diabetes and Metabolic Nutrition course teaches it, and Dr Sucharita Sengupta, who holds an MSc in Food Science and Nutrition and a PG Certificate in Diabetes Education, is among the faculty. For personal guidance, NNWA's diet and lifestyle clinic offers everyday consultations with qualified practitioners, alongside your doctor's care; it does not treat diabetes or change medicines.

The festive season with diabetes: the short version

Keep checking your blood sugar and aim for the targets your doctor has set. Eat one small sweet after a meal, not on an empty stomach, and cut back rice or roti to make room. Start meals with vegetables and protein, finish with the starch and the sweet, and walk for 10 minutes afterwards. Treat sugar-free mithai as a partial improvement, not a free pass. Talk to your doctor before any fast, especially on insulin or sulfonylureas, and before drinking at parties. Carry a fast sugar for lows. If readings stay high for more than a day or two, or you feel unwell, get medical help rather than waiting for the festivals to end.
