Decoding Fasting In Diabetes

Fasting is a common practice embraced by individuals for various reasons, including religious and spiritual beliefs, detoxification, self-reflection, and weight management. Although blood sugar levels are seen to reduce with fasting, the effects of fasting on glucose control and weight loss have been inconsistent, indicating the need for further investigation in this area.

In this article, we aim to assist you in making informed decisions regarding your fasting approach while managing diabetes.

Is Fasting Safe for Individuals With Diabetes?

When it comes to fasting, it's ultimately up to you and what feels right for your body, keeping in mind that your health should always come first. If you decide to fast, it's highly recommended to discuss it with your doctor to ensure that you are free from any type of health risk. They may provide guidance and support and change in dose of medications depending on your specific needs.

Risks to Look Out for When Fasting if You Have Diabetes

Before we explore important considerations during fasting, let's take a moment to understand the potential risks associated with fasting if you have diabetes:

• If you take diabetes medications like insulin, you are at risk of hypoglycaemia (blood sugar levels dropping too low) when you fast. If you experience hypoglycaemia while fasting, you should take food or liquids along with your treatment for hypoglycaemia.
• On the other hand, if your blood sugar levels rise, it could lead to a condition called diabetic ketoacidosis (DKA), which may require hospitalisation. If you're fasting and notice high blood sugars, you will need to consume sugar-free fluids to lower the risk of DKA.
• Dehydration is a potential risk during fasting and may vary depending on the type of fast. In cases of complete (waterless) fasting where no liquids are allowed or if you are taking medicines like diuretics (to increase urine output), the risk of dehydration increases.

Always Take Extra Precautions

Remember to consult your doctor before you begin fasting to discuss how to manage diabetes while fasting.2 They may provide valuable insights and help you plan and navigate your fasting routine in a manner that aligns with your health goals and specific needs. If you do decide to give fasting a try, here are some helpful tips to keep in mind.

1. Monitor Your Blood Sugar Levels

Take the time to review and evaluate your glucose monitoring measures, considering any specific requirements during fasting, such as managing low or high blood sugar episodes. Additionally, address any other individualised priorities such as food choices.

2. Pay Attention to What You Eat

Before you begin your fast: If you have diabetes and are fasting, consider incorporating more slowly absorbed foods with a lower glycaemic index just before starting the fast. Low glycaemic index foods, such as nuts, vegetables, and fruits, might help you feel full and maintain more stable blood glucose levels throughout the fasting period.

When you are fasting: Here are some key points to consider for your nutrition during fasting:

• Include whole fruits to feel full and curb those cravings for sweets.
• For those who can eat vegetables, aim for a variety of fresh and seasonal vegetables, using olive oil and vinegar/lemon juice for better absorption of nutrients.
• Make soups with plenty of vegetables, legumes, and whole grains.
• Choose lean protein sources and legumes to reduce cholesterol and saturated fat.
• Use unsaturated oils like olive oil and restrict fried foods.
• Enjoy nuts and seeds in moderation for healthy fats and nutrients.
• Pick low-fat based dairy products or plant-based milk.
• Enhance the flavour with condiments like herbs and spices instead of excessive salt or sugar.

When breaking the fast: Limit your intake of fatty and sugary foods such as sweets or cakes as excessive consumption of these may be harmful to your health. Choose cooking methods that use less oil, like grilling, baking, or air frying and use non-stick pans or air fryers to reduce added fat.

Maintain Proper Hydration

Stay hydrated by drinking enough water and unsweetened beverages. When it comes to fasting, individuals with diabetes may usually enjoy beverages like water, diet soda, tea, or black coffee without hesitation. These choices may help you avoid dehydration and keep you refreshed throughout the day.

Conclusion

Fasting may be an individual choice for those with diabetes but it requires careful consideration and consultation with doctors. It's essential to prioritise your health, maintain conscious eating habits, and monitor your blood sugar levels effectively during fasting.

By making informed choices and seeking a professional’s guidance, you may enjoy your fasting and keep your blood sugar levels in control.
