Intermittent fasting helps people with diabetes lower sugar levels: Study

Restricting eating to certain times -- a regimen known as intermittent fasting -- may be the best way to help people with Type 2 diabetes lose weight and lower blood sugar levels.

Researchers found that people with Type 2 diabetes who ate only between noon and 8 p.m. lost more daily weight than those who counted calories.

Both strategies resulted in similar improvements to participants' blood sugar levels.

"Many people find counting calories very hard to stick to in the long term, but our study shows that watching the clock may offer a simple way to decrease calories and lose weight," said researcher and study presenter Vicky Pavlou, a doctoral student at the University of Illinois at Chicago.

"Although time-restricted eating is becoming increasingly popular, no other studies have looked at an eight-hour eating window in people with Type 2 diabetes," she said in a meeting news release.

The eight-hour window had been previously studied in people with obesity. Type 2 diabetes is a metabolic disorder that is strongly associated with being overweight or obese.

For this study, a team led by Krista Varady, a professor of nutrition at UIC, studied a group of 75 racially and ethnically diverse people who had obesity and Type 2 diabetes. They ranged in age from 18 to 80.

Participants were placed into one of three groups: time-restricted eating, calorie restriction and control.

Those in the time-restricted group ate only between noon and 8 p.m. The calorie-restriction group could eat at any time of the day; they used a mobile app to count their calories. Their objective was to reduce calorie intake by 25% from the level needed to maintain their current weight. The control group ate their normal diet.

Compared to the control group, people on the time-restricted eating diet lost 3.55% of their body weight over six months while the calorie restriction group lost none.

Compared to the control group, blood sugar (HbA1C) levels dropped in both the time-restricted group (-0.91%) and the calorie restriction group (-0.95%).
