Intermittent Fasting Could Help Manage Blood Sugar in Diabetics

Colorful food and cutlery arranged in the form of a clock on a plate. Olive in hand. Intermittent fasting, diet, weight loss, lunch time concept.New research has found that intermittent fasting (IF), a popular eating style, may help people with type-2 diabetes better control their blood sugar.

The study found that people with diabetes who restricted their eating to a daily 10-hour window had blood sugar levels in the normal range for about three hours longer than when they ate whatever they pleased.


The patients also experienced lower 24-hour blood sugar levels and consistently lower morning fasting glucose when they participated in a time-restricted eating pattern.

For the small study, 14 adults with type-2 diabetes were asked to limit their food intake to a 10-hour window each day, with 6 PM being the cutoff point. They wore a continuous glucose monitoring device that measured blood sugar every 15 minutes.

People were told to eat how they usually would during their intake window, with no food restrictions. They spent three weeks on the IF diet and another three weeks eating without any time limitations.

During the time-restricted eating, the participants had normal blood sugars for an average of 15 hours per day, compared to 12 hours when they ate whenever they wanted.

The 10-hour window was also safe for the participants, who did not experience any significant increase in hypoglycemia (low blood sugar) or any other serious side effects.


When you fast, your body breaks down glycogen stores, which is sugar stored in the body. When they are gone, your body turns to using fat. In essence, it optimizes sugar metabolism to limit excess sugar in the bloodstream. It can also contribute to some fat loss.

A 10-hour eating window is also relatively generous as other types of IF set a 6 – 8 hour feeding window.

What’s also interesting about this study is that there were no dietary limitations. If there were, for example, participants told to eat more fruits and vegetables and healthy fats, while limiting processed foods, the results may have been even better.
