When you Ask your doctor how to manage diabetes while fasting, and the answer is usually the same: ‘it’s better if you don’t fast.’ But when your heart is set on honoring Maa Durga, that advice is easy to set aside.
If you have diabetes, you’re usually torn between following your physician’s advice, who’s only looking at your HbA1c levels, and the spiritual importance of vrat.
With Sharadiya Navratri 2026 running from Sunday, October 11 to Tuesday, October 20, millions of Hindus are getting ready for nine days of devotion, prayer and ritual fasting.
But you don’t really have to choose. You just need to find a better, more structured plan rather than just starving yourself.
This guide can help you choose the right kind of food, in the correct portions and give you some tips for fasting with diabetes, so that you finish your Navratri fast safely.
Is It Safe for Diabetics to Fast During Navratri?
Some diabetics, with more controlled blood sugar levels, may be able to fast during Navratri, but only with the guidance of their doctor and strict planning.
Some of the reasons your doctor may advise against it, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) are:
- Severe hypoglycemia: You might have dangerously low blood sugar levels if you skip your food while still continuing to take your regular diabetes medication.
- Hyperglycemia: Breaking a fast with starchy fasting food like sabudana, may cause sharp blood sugar spikes.
- Dehydration: Your high blood sugar levels can force your kidneys to work extra to remove excess glucose, drawing water out of the body.
But this doesn’t mean you should completely avoid fasting as all Navratri fasts may not be the same.
Here are the fasts usually done and, based on guidelines from the International Diabetes Federation, how they may affect diabetics:
- Nirjala Vrat (No food or water): Strictly avoid as dehydration may concentrate your blood glucose and cause kidney stress or diabetic ketoacidosis.
- Only fruit fast (Phalahar): Not usually recommended since fruits contain high sugar and may cause unpredictable blood sugar spikes and crashes later on.
- Single meal fast (Ekana): Might be a high risk for diabetes because not eating at all during the day may lead to low blood sugar, and a heavy evening meal after that will spike your blood sugar.
- Flexible/partial fast (small meals): Here you eat low-glycemic vrat foods more frequently. It’s recommended since it may help prevent extreme blood sugar fluctuations.
Always speak with your doctor before fasting and inform them what type of fast you’re doing, so that they can adjust your medication dosages accordingly.
What Happens to Blood Sugar When You Skip Regular Meals During Navratri?
When you skip regular meals during Navratri, it may cause your blood sugar to swing unpredictably between sudden drops and sharp rebound spikes.
- If you don’t eat, your body uses up the glucose in your blood and you may have low blood sugar (hypoglycemia).
- Stress hormones like cortisol and adrenaline may then get released which forces your liver to release its stored glucose.
- When you eventually do eat, the excess glucose in your bloodstream may cause a sudden spike.
- Not eating regularly can affect insulin resistance and may stress your pancreas over time.
If you skip meals, you often get hypoglycemia (low blood sugar). Watch out for these signs:
- Jittering or shivering
- Sweat
- Rapid heart rate
- Confused or dazed
- Dizziness
- Severe tiredness
If any of these occur, don’t just brush it off. Break your fast by finding something with sugar to eat and check your blood sugar immediately.
Which Navratri Fasting Foods Spike Blood Sugar the Most?
During Navratri fasting, the highest spikes in blood sugar may be caused by those vrat foods high in starch and sugar.
| Navratri Fasting Food | Blood Sugar Impact | Diabetic-Friendly Approach |
| Sabudana (tapioca pearls) in khichdi and vadas | Very High – Pure starch with no fiber. Causes a fast sugar rush | Eat small amounts. Mix with peanuts, vegetables or curd to slow it down |
| Potatoes (aloo) | High – Breaks down into glucose very rapidly | Swap it for sweet potatoes, or eat it with paneer for a protein boost |
| Sweets & juices(kheer, halwa, lassi) | Very High – Added sugars go straight into your bloodstream | Don’t have refined sugar. Eat whole fruits instead of drinking juice |
| Fried puris & pakoras(kuttu, singhara) | Moderate to High – Deep frying can add heavy carbs and oil | Don’t fry. Use the flour to make rotis or pan cooked cheelas instead |
| Makhana (foxnuts) & nuts | Low – High in protein and fiber. Keeps sugar steady | Roast with little ghee and salt for a healthy snack |
| Samak rice & rajgira(millets, amaranth) | Moderate – Has more fiber and protein than regular rice | Keep portions small and have with some vegetables |
Note: This table is just a general guide. Exact impact may vary based on each individual person and their preparation method.
What Can Diabetics Eat During Navratri Fasting to Keep Blood Sugar Stable?
Diabetics may maintain stable blood sugar levels during Navratri by choosing high-fiber, low-glycemic carbs, lean proteins and healthy fats.
Here’s a few smart food choices you could consider:
- High-fiber flours: Replace starches with buckwheat (kuttu) or amaranth (rajgira) to make rotis instead of deep fried puris.
- Protein and healthy fats: Having some paneer, curd, almonds or walnuts may help you stay full for longer and slow down sugar absorption.
- Non-starchy vegetables: Eat a lot of vegetables like bottle gourd (lauki), cucumber and pumpkin cooking it with less oil or ghee.
- Eat small, frequent meals: Spread your meals into smaller portions across the day rather than one large meal after fasting to avoid high spikes.
You can make these changes especially if you’re only prediabetic to make sure it doesn’t turn fully into diabetes. A 7-day Indian diet meal plan for prediabetes may also help you find a realistic plan to follow even during your festive season.
Can Diabetics on Insulin or Medication Safely Fast During Navratri?
Yes, diabetics on medication may fast but only with strict medical guidance and careful planning.
Here’s how you can fast safely:
- Before you start fasting, always speak to your doctor about your medicine doses. A high dose in fasting conditions may lead to very low blood sugar.
- Check your blood sugar multiple times a day so that you may catch any sudden drops or spikes.
- Break your fast immediately and eat something sweet if you feel any low blood sugar symptoms, or if your blood sugar is below what your doctor recommended.
- Choose healthier fasting food like buckwheat (kuttu), foxnuts (makhana), paneer or curd. Avoid deep fried and sugary snacks.
We won’t give specific dosage guidance for your medications, since that has to come only from your own doctor, based on your previous medical and blood sugar history.
How Often Should Diabetics Check Blood Sugar During Navratri Fasting?
Diabetics fasting during Navratri should check their blood sugar at least 4 times a day. Once before starting the fast, at midday, in the late afternoon and before breaking or eating a meal.
You may monitor your blood sugar using this schedule:
- Morning: Right after waking up.
- Midday: Around lunch to see your starting level.
- Late afternoon: When you may have lower blood sugar.
- Before dinner: When you’re about to break your fast.
- After meals: Check to observe how your body responds to certain food.
- If you notice hypoglycemia symptoms: Check immediately if you feel dizzy, weak or you’re sweating with a quick heart rate.
Keep a simple log across all 9 days so that you can spot patterns. You’ll also see which foods or fasting styles cause the biggest spikes for you.
How Should Diabetics Break Their Navratri Fast Safely?
Diabetics may break fast during Navratri with small portions of protein, healthy fats and low glycemic complex carbs. Don’t have any fried or sugary food as it may cause sudden blood sugar spikes.
These are the steps you can take to break your fast safely:
- Check your blood sugar first and have some fast acting sugar ready if you find it too low.
- Start with water and fiber like chaas or coconut water
- Have a small portion of protein like a few peanuts or a spoon of curd
- Choose low-GI starches in small portions along with vegetables instead of deep fried foods or plain refined carbs
- Avoid sweets or fried food. If you must eat them, save it for after the meal.
- Take a short walk after eating, if you’re able to. This may help manage the post-fast sugar spikes better.

Case Study: Fasting Safely With Type 2 Diabetes
(The scenario below is a composite example created to illustrate the approach in a real-life setting.)
Sunita, 58 from Jaipur, has been managing type 2 diabetes for six years. She had skipped Navratri fasting before, worried it wasn’t safe for her. This year, she wanted to fast again but didn’t know how to do it without risking her health.
She spoke to her doctor and he adjusted her medication timing for the fasting days. She came to ThriveCore for a personalised online nutrition plan to help her get through the fasting. During the nine days, her coach built her a single meal fasting plan adjusting her protein and carb intake with each meal.
On the fourth day, her afternoon reading was lower than her normal range. So, her coach advised her to break her fast early that day with peanuts and water, rather than pushing through.
By the ninth day, her readings were observed to be more stable than it was when she previously fasted without a plan.
“I used to think that with diabetes I would never be able to fast. Once my coach planned it properly for me, it wasn’t a struggle. I actually finished all nine days without any issues for the first time in years.” – Sunita

No, you should never skip or change your diabetes medication on your own while fasting. Always make sure to meet with a doctor to discuss doses before deciding to fast.
What are the warning signs of low blood sugar while fasting?
The warning signs of low blood sugar, especially during fasting are shaking, sweating, feeling and having a fast heartbeat. If you feel any of these, break your fast quickly and check your blood sugar.
Can diabetics drink only milk and fruit during Navratri fasting?
No, diabetics should not restrict their Navratri fast to only milk and fruit. Drink just plain water or coconut water instead of milk. If you want to eat fruit, you can choose low glycemic options and eat some nuts with it.
