New Study Shows That Type 2 Diabetes Reversal Is Very Difficult


The pursuit of reversing type 2 diabetes through weight loss has captivated the medical community, with clinical trials often showcasing significantly higher success rates than those observed in real-world scenarios. While conventional treatments such as insulin injections play a crucial role in maintaining healthy blood sugar levels, the potential for reversing type 2 diabetes remains a compelling prospect for those who manage to shed excess weight. However, a substantial and perplexing gap exists between the outcomes witnessed in meticulously structured clinical trials and the more challenging landscape encountered in everyday life.

Clinical trials, characterized by their structured support systems and diverse interventions, present a more favorable environment for achieving type 2 diabetes reversal through weight loss. Hongjiang Wu and his team from the Chinese University of Hong Kong sought to unravel the intricacies of this phenomenon by meticulously examining data from over 37,000 individuals diagnosed with type 2 diabetes between 2000 and 2017.

In the realm of real-world challenges, where the comprehensive support systems of clinical trials are notably absent, fewer than 10% of individuals with type 2 diabetes manage to reverse their condition through weight loss. 

This figure continues to dwindle even when tracking progress over several years. The pronounced discrepancy between clinical trials and real-world scenarios can be attributed to the multifaceted support, varied interventions, and differing definitions associated with clinical trials, where the very definition of type 2 diabetes reversal may vary.

The researchers undertook a meticulous examination of participants over an average duration of nearly eight years, focusing on weight changes during the initial year post-diagnosis. The reversal of type 2 diabetes was determined by measuring glycated hemoglobin (HbA1c) levels in consecutive tests carried out six months apart, with the criterion being HbA1c levels consistently less than 6.5%.

Key Findings: Real-world Remission Rates


The team, in its initial assessment, opted to measure weight only one-year post-diagnosis. This revealed that 2% had entered remission, while an alarming half had gained weight during this period.

By the study’s comprehensive conclusion, it was discerned that 6% of participants had experienced remission at some point. However, a staggering two-thirds of these individuals eventually required diabetes drugs to regain control within three years.

In stark contrast to the real-world findings, small-scale clinical trials have reported remarkable remission rates—up to 86%—for individuals with type 2 diabetes who underwent substantial weight loss within a year. It is noteworthy that such trials often encompass a range of professional interventions, including dietary management, exercise programs, moral support, consistent monitoring, feedback mechanisms, reminders, and encouragement.

Wu acknowledges that the study’s limitations include the sole recording of weight one-year post-diagnosis, leaving uncertainties about subsequent weight changes or the influence of other contributing factors. Notably, outside the controlled environment of clinical trials, physicians may exhibit hesitancy in recommending treatment cessation for individuals with type 2 diabetes, contributing significantly to the observed differences.

This study contributes valuable insights into the intricate dance between clinical trials and the formidable challenges encountered in the quest for type 2 diabetes reversal through weight loss. Bridging this substantial gap requires a comprehensive understanding of the multifaceted factors influencing outcomes and underscores the pivotal role of tailored support systems in real-world scenarios, where challenges are diverse, and interventions need to be nuanced and adaptable.
