What is the effect of fasting on diabetes?

An important goal of diabetes care or diabetes management is to keep blood sugar levels within normal limits. A good diabetes management plan prevents blood sugar from going up or down. This sugar control becomes a bit difficult during fasting days because the food eaten after fasting is not suitable for blood glucose. However, fasting or fasting gives rest to the digestive organs due to which the body does self-repairing while being energetic. That’s why science also supports fasting in the week. It rejuvenates the body. But it is necessary to take a right diet in diabetes, so it becomes even more important to manage this diet during fasting. Therefore, by following a proper diet, you can make your body healthy along with your fast.

A right and ideal diet plan during fasting

Different communities and states follow different diets as fasting food. The method of making them is also different. It doesn’t have to be an ideal diet plan. For this, a nutritionist or healthcare provider should make a good fasting diabetic diet according to the diet of each state. Apart from this, some people eat only once during fasting or fasting and some people fast for the whole day. Also, some people use fruits, vegetables and dairy products. Therefore, prepare your diet plan according to all these, which will keep blood sugar under control.

Food Structure

A fasting plate should include all major food types. Most importantly, consume carbs judiciously throughout the day. Complex carbs, as well as low-calorie beverages, have a lower GI than simple carbs and concentrated beverages. In this case, definitely include them in your diet. Including an adequate amount of liquid in your diet gives the following benefits:

  • hydrating the body, and
  • preventing dehydration.

During non-fasting, walk for 15-20 minutes as a necessary physical activity and walk after meals.


Be sure to include grains in your food plate. Thus it is considered safe to eat grains during fasting. They provide enough sugar and energy for the body organs to function properly. Carbs should account for about 50-60% of the total kilocalories per day.

High GI foods adversely affect body weight. In addition, they increase glucose levels and insulin resistance. Apart from this, it also increases the production of free fatty acids after eating. Therefore, during fasting or fasting, include cereals along with other foods such as vegetables, dietary fiber as well as small amounts of oil. They reduce the total glycemic load of the diet plan.


About 15% to 20% of total energy should be met from protein to make a good and ideal diet. This need may be different from person to person. Special cereals, garlic, onions, pulses and many other protein rich food are not eaten during fasting. In place of them, low-fat dairy products are used which supply protein.

Apart from this, sugar-free shake, flavored masala milk, whey, raita, lassi, buttermilk and nuts can be included as fast food.


Fat should contribute less than 30% of total calories to the daily requirement. Research studies show that low fat, moderate-carb, as well as high fiber diets, significantly reduce HbA1C. That’s why they should be included in the right quantity even in fasting. Additionally, the particular fatty acids or fatty acid composition of fats and oils play an important role in the diet plan of diabetic patients. It is best to include less than 10% cholesterol and less than 300 mg of saturated fat per day.

Additional scientific research studies confirm that reducing saturated fatty acids or increasing monounsaturated fatty acids can increase the activity of glucagon peptide-1, thus reducing postprandial transglucosidase.

In addition, omega-3 fatty acids (flaxseeds are excellent sources, which are usually allowed during fasting) have been shown to be associated with a reduction in the risk of biomarkers of heart problems in type 2 diabetes. Nuts are considered an excellent source of protein during fasting, so be sure to add them to your fasting diabetic diet.

Vitamins And Minerals

Including fruits and vegetables in your diet can increase plasma carotenoids as well as vitamin C, which is a rich source of antioxidants and phytocompounds. When fibrous vegetables are combined with a high-carb-high-fat meal, its glycemic load is reduced. It also lowers postprandial glucose levels. Whole fruits (with pulp), fresh vegetables, and fiber are a good choice instead of juice.

Whole fruits, as well as leafy greens, are high in fiber, low in glycemic load, as well as high in micronutrients while being low in energy density. In addition, it has a positive effect on total and LDL cholesterol levels. Therefore, in a better fasting diabetic diet, instead of eating juice or sugar, take salad, fruit chaat, custard, vegetable smoothie, or vegetable soup as a mid-meal.

Fiber Or Filament

Make sure to include 25 grams of fiber per 1000 calories or 30-40 grams throughout the day in your diet during fasting or fasting. There are a lot of changes in your food habits, patterns and timings during the days of fasting, due to which it becomes even more important to control the sugar level.

Plenty Of Water And Fluids

Make sure to add low-calorie drinks like green tea, lemonade, lassi, buttermilk, whey, mint water etc. to your fasting diet to quench thirst especially during summer. It is better to avoid eating sweets during fasting days.
