I have always wondered about the benefits of fasting as a strategy for managing my blood sugar with diabetes.  In recent years, intermittent fasting (IF) has gained popularity as a potential strategy for weight loss and improving overall health; however, when living with diabetes, is intermittent fasting safe and effective? 

What is Intermittent Fasting?

Intermittent fasting involves cycling between periods of eating and fasting.  The most common methods include the 16/8 method (fasting for 16 hours, eating within an 8-hour window), alternate-day fasting, and the 5:2 diet (eating normally for five days and restricting calories for two days).  Proponents of intermittent fasting suggest it can help control blood sugar levels, promote weight loss, and improve insulin sensitivity.  Just what we want with diabetes, but does it really work?

For individuals with diabetes, managing blood sugar levels is paramount.  Research on the effects of intermittent fasting in diabetes management has shown some promising results.  Several studies indicate that fasting can lead to weight loss, reduced insulin resistance, and improved glycemic control in some individuals with type 2 diabetes. However, it is crucial to approach intermittent fasting with caution and under medical supervision, especially for individuals taking medications that can cause hypoglycemia (low blood sugar).

Benefits of Fasting?

One key benefit of intermittent fasting for individuals with diabetes is its potential to promote weight loss.  Excess weight and obesity are significant risk factors for type 2 diabetes and can contribute to insulin resistance. By promoting weight loss, IF can help improve insulin sensitivity and glucose metabolism, improving blood sugar control over time.

Moreover, intermittent fasting has been associated with beneficial changes in biomarkers, such as reduced inflammation, improved lipid profile, and enhanced cellular repair processes (autophagy). These effects may offer additional health benefits beyond blood sugar management for individuals with diabetes, including cardiovascular health and overall well-being.


Despite the potential benefits, intermittent fasting is not suitable for everyone with diabetes.  Individuals using insulin or certain oral medications to manage diabetes need to be cautious about fasting, as it can increase the risk of hypoglycemia.  

While intermittent Fasting may work well for some, it may not be for all.  Please consult with a healthcare provider before starting any fasting regimen, especially for individuals with diabetes or other medical conditions.

The End

When considering intermittent fasting with diabetes, it is crucial to balance your diet.  Lean proteins, healthy fats, fibre-rich carbohydrates, and plenty of vegetables can help support stable blood sugar levels and overall health within an overall strategy of intermittent fasting.

In conclusion, intermittent fasting may be good for weight loss and blood sugar control, but individualized approaches based on medical history, current medications, and overall health status are necessary.  That includes all of us with diabetes.  

Remember, managing diabetes requires a comprehensive approach integrating medical guidance, lifestyle modifications, and ongoing monitoring.

Always prioritize your health and safety by consulting qualified healthcare professionals for personalized diabetes management strategies.
