New Study Reveals Weight Loss Is Not Necessary to Reverse Prediabetes

New Insights on Managing Prediabetes

For those grappling with high blood sugar levels, weight loss has often been seen as the go-to strategy to prevent the onset of diabetes. However, a recent study is challenging that norm by examining alternative methods to lower blood sugar levels effectively.

An international research team discovered that by adhering to specific dietary and exercise guidelines, individuals could reduce their risk of developing type 2 diabetes by up to 71%, even if they didn’t lose any weight at all.

While this study doesn’t undermine the role of weight loss in mitigating diabetes risk, it may inspire a broader perspective on what to prioritize in prediabetes treatment strategies. “The key goal is to restore normal fasting blood sugar levels—not just focus on the scale,” notes diabetologist Andreas Birkenfeld from the University of Tübingen in Germany.

The study involved 1,105 participants diagnosed with prediabetes who were given recommendations to enhance their diet and exercise over a 12-month period. Interestingly, among the 234 participants who didn’t lose weight by year’s end, 51 still managed to meet the criteria for prediabetes remission.

Follow-up evaluations of these participants extended up to 10 years. Those in the remission group were about 71% less likely to transition to type 2 diabetes compared to the 183 who did not achieve remission.

This result mirrors a similar finding: a 73% reduction in diabetes risk was observed in individuals who lost weight and reached prediabetes remission after a year, when compared to those who lost weight but did not achieve remission.

Additionally, an analysis of a subset of participants indicated that where fat is stored in the body plays a crucial role. Those who normalized their blood sugar levels without shedding pounds had lower levels of visceral fat compared to those whose blood sugar remained high.

This aligns with existing knowledge linking visceral fat to insulin resistance. “Regular exercise and a balanced diet positively impact blood sugar, independent of weight loss,” Birkenfeld adds. “While weight loss is beneficial, our findings imply it isn’t absolutely necessary for diabetes prevention.”

The researchers advocate for a shift in prediabetes treatment guidelines, suggesting less emphasis on body mass—an approach that might discourage individuals at risk who struggle with weight loss.

In the future, treatment and prevention strategies for type 2 diabetes should focus primarily on blood glucose control and fat distribution rather than just weight, according to Reiner Jumpertz-von Schwartzenberg from the University of Tübingen.
