Late-night snacking often leans towards calorie-dense, high-carbohydrate, and sugary foods—choices that can significantly impact blood sugar levels.
“These commonly preferred late-night foods are not only high
in calories but also tend to spike blood glucose levels rapidly,” says By Dr. V. Mohan, Chairman and Chief Diabetologist, Dr. Mohan’s Diabetes Specialities Centre.
Some of the most common culprits include:
Biryani – High in calories, refined carbohydrates, and fat; it can spike blood sugar and often cause indigestion.
Ice cream and desserts – Loaded with sugar and fat, leading to prolonged glucose elevation.
Sweetened beverages (soda, energy drinks, fruit juices) – Liquid sugars are absorbed quickly, causing sharp spikes in blood glucose.
Refined and processed foods (white bread, pasta, pizza, white rice) – These simple carbohydrates break down rapidly into glucose. While fatty toppings may slow digestion slightly, they still result in elevated glucose levels late at night.
Fried foods (fries, samosas, pakoras) – High in refined carbohydrates and unhealthy oils, which can worsen insulin resistance.
Packaged snacks (biscuits, chips, instant noodles) – Contain refined starches and additives that contribute to blood sugar instability.
Sugary sauces (ketchup, barbecue sauce, sweet chili sauce) – Often overlooked but high in hidden sugars.
Dr. V. Mohan explains that timing also plays a critical role. “After 8 PM, the body’s insulin sensitivity naturally decreases, meaning glucose remains elevated for longer periods,” he says.
Consuming high-sugar foods late at night can also interfere with sleep quality. “High sugar intake before bedtime can disturb sleep, cause fatigue, and lead to morning brain fog,” adds Dr. V. Mohan.
Over time, such habits may increase the risk of gastric issues, type 2 diabetes, obesity, and other metabolic disorders.
Smarter Alternatives for Late-Night Cravings
Making small swaps can help stabilise blood sugar while still satisfying cravings.
“Choosing foods that are lower in refined carbohydrates and higher in fibre or protein can make a significant difference in maintaining stable glucose levels,” says Dr. V. Mohan.
| Common Choice (High Spike) | Better Alternative (Stable Energy) |
|---|---|
| Biryani | Keep portions small and prepare with more vegetables and less oil and spice to reduce impact |
| Biscuits / Cream cookies | Dry roasted makhana (fox nuts) – crunchy, light, low glycaemic |
| Instant noodles | Vegetable wheat rawa upma or poha – fibre-rich, slower digestion |
| Fried samosas / pakoras | Steamed mini idlis with vegetable chutney or sambar |
| White bread toast with jam | Whole wheat chapati roll with paneer or vegetables |
| Sweetened yogurt / flavoured lassi | Fresh low-fat curd or plain Greek yogurt with cucumber or mint |
| Potato chips | Roasted chickpeas or peanuts – rich in protein and fibre |
| Ice cream | A fruit bowl with papaya, guava, or apple slices |
