What is Intermittent Fasting? 

Intermittent fasting refers to a series of diets that includes alternating between times you may eat and times you must fast. Depending on the diet you choose, fasting restrictions may be set to specific days of the week or certain times of the day. 

The Different Types of Intermittent Fasting 

Intermittent fasting diets provide flexibility as dieters can choose from several fasting periods. The most popular forms of intermittent fasting for diabetes diets include: 

• The 16/8: This is the most popular fasting diet because it is considered the most sustainable. This diet restricts eating to eight hours each day. You choose an eight-hour window that you would like to have meals within, and you fast for the remaining 16 hours. For best results, your fasting period must remain consistent throughout the week. 

• 5:2: Fasting: In this form of intermittent fasting, you will select two nonconsecutive days to restrict your caloric intake to around 500 to 600, but you can eat at any time of the day. You eat normally on the remaining five days of the week. 

• Alternate day fasting: This is considered the most difficult intermittent fasting diet. You eat your regular diet one day and then either fast or eat a meal containing less than 500 calories the following day. 

You must eat a balanced diet during eating periods and choose healthier snack alternatives, especially when your caloric intake is restricted. 

The Effects of Intermittent Fasting on Blood Sugar 

Calorie restriction and fasting can improve insulin sensitivity and reduce insulin levels. Because of this, people with diabetes who intermittently fast can better control their blood sugar levels while fasting and shortly after eating. 

Can You Use Intermittent Fasting to Reverse Diabetes? 

There has been some evidence to suggest a link between intermittent fasting and type 2 diabetes remission. In a small study, insulin-dependent diabetics were able to improve their insulin resistance and cease diabetes treatment. Additionally, the diet resulted in significant weight loss and reduced haemoglobin levels in these patients. 

Additional Benefits of Intermittent Fasting for Diabetes 

Intermittent fasting for diabetes can not only provide better blood sugar control, but it may also provide the following benefits:  

• Weight loss 

• Improved brain health 

• Improved heart health 

• Reduced risk of obesity-related illnesses, including some forms of cancer and sleep apnea 

• Reduced risk of inflammation-associated conditions, such as arthritis, asthma, and stroke 

Intermittent Fasting Diabetes Risks and Precautions 

Intermittent fasting for diabetes is not without risks, and you must be aware of these risks before starting a new diet. Intermittent fasting may bring about side effects such as: 

• Fatigue 

• Changes in mood

• Persistent hunger 

• Nausea

• Headaches 

• Insomnia 

Patients with diabetes may be more likely to experience these symptoms. Furthermore, the most significant risk of fasting for diabetic patients is a sharp increase in blood sugar levels after fasting or low blood sugar levels when fasting. 

Eating foods that contain high levels of carbohydrates or sugars after breaking a fast can result in blood sugar levels that are too high, resulting in hyperglycemia. During fasting, people with diabetes can also be at risk of developing hypoglycemia, or low blood sugar, especially patients with type 1 diabetes.

If you have diabetes and would like to try intermittent fasting, it is essential to be aware of the signs of low and high blood sugar levels to avoid either of these conditions. You also need to avoid intense workouts during periods of fasting, as vigorous exercise can make your blood sugar levels fall further. 

If you are currently managing diabetes, it is recommended that you speak with your primary healthcare provider about dietary changes before you begin intermittent fasting. Your healthcare team can help ensure that you start intermittent fasting safely and make any necessary adjustments to your medication. 

The Bottom Line

Intermittent fasting for diabetes can help patients lose weight, improve insulin sensitivity, and gain better control over their blood sugar levels. Intermittent fasting is safe for most people, but it does come with its risks. Therefore, should you choose to begin intermittent fasting for diabetes, you must speak with your healthcare provider and monitor any symptoms you experience.
