Time restricted eating or fasting causes levels of insulin to decrease which helps diabetes. There are several other benefits to fasting such as improved thinking, memory, energy, and heart health. By giving your stomach a rest in the evening, you also allow your brain time to remove toxins while you sleep.
Fasting in people with diabetes should be done VERY cautiously as low blood sugars may cause a host of issues including loss of consciousness, seizures and even death, but if done carefully, and while eating foods that promote blood sugar stability, the benefits of fasting could be great.
Fasting promotes increased insulin sensitivity, lower blood sugars, and weight loss. Fasting does not slow down your metabolism like a calorie restricted diet and helps you burn stored fat!
Certain medications such as insulin or sulfonylureas increase your risk for low blood sugars, so check with a healthcare professional before participating in any fasting or time restricted eating.
I recommend starting with a 12 hour fast; meaning if you stop eating at 7pm, you wait to eat until 7am. Be sure to drink plenty of fluids to prevent dehydration.
Stop fasting if you have low blood sugars or signs of low blood sugars. Be sure to check your blood sugars and then have a quick sugar/carbohydrate with 15-20 grams of simple carbohydrates (like 3-5 candies, 1/2 cup of juice, or 1/2 cup of full sugar soda).
