A New Hope for Diabetes Control: The Promise of Intermittent Fasting and Meal Replacements

In a revolutionary clinical trial set in China, a fresh approach may transform the management of type 2 diabetes for adults. The study, known as the EARLY (Exploration of Treatment of Newly Diagnosed Overweight/Obese Type 2 Diabetes Mellitus) trial, reveals promising results for a 5:2 intermittent fasting meal replacement diet. This method, effectively compared with commonly prescribed diabetes medications, has demonstrated significant improvements in short-term glycemic control and weight loss.

Between November 2020 and December 2022, the EARLY trial enrolled 405 participants, randomly assigned to either the 5:2 meal replacement group, or groups taking metformin or empagliflozin over 16 weeks. The 5:2 diet consists of two nonconsecutive fasting days and five days of standard eating per week coupled with meal replacements; a design that could offer a novel dietary therapeutic angle for diabetes care.

Excitingly, the study's results showed that participants on the 5:2 meal replacement diet witnessed the greatest improvement in hemoglobin A1c levels—a measure of blood sugar control—compared to those on metformin or empagliflozin. Moreover, weight loss was more significant in the meal replacement group, an influential factor considering the intricate link between obesity and type 2 diabetes.

As obesity and diabetes rates soar across the globe, and particularly in China, innovative and pragmatic treatments like the 5:2 meal replacement diet could have immense impacts on public health and individual wellbeing. The diet's remarkable performance underscores its potential as an effective lifestyle intervention, possibly even standing as an alternative to antidiabetic drugs.

While the findings tout the success of the diet in improving glycemic outcomes and instigating weight loss, it should be noted that the study focused on Chinese adults with early type 2 diabetes. Further exploration is necessary to establish its efficacy in diverse populations and over longer periods.

The EARLY trial, registered under the Chinese Clinical Trial Registry (ChiCTR2000040656), was published open access in JAMA Network Open with the complete trial available through a doi:10.1001/jamanetworkopen.2024.16786.

Could the 5:2 intermittent fasting meal replacement diet be a cornerstone in early diabetes management? Its emergent success in clinical settings heralds a promising new chapter in the fight against diabetes.
