A groundbreaking study published in Diabetologia in December 2023 by Germán D. Carrasquilla and colleagues has unveiled significant insights into how changes in body size from childhood to adulthood can affect the risk of developing type 2 diabetes. Unlike the risk of cardiovascular disease, which appears to be primarily influenced by adult body size, the study found that transitioning from a low body size in childhood to a high body size in adulthood significantly increases the risk of type 2 diabetes.
Key Findings
Study Design and Population
The research utilized data from the UK Biobank, involving 364,695 individuals of European ancestry who were initially free of type 2 diabetes and cardiovascular disease. Participants were categorized based on their self-reported body size at age 10 and their measured Body Mass Index (BMI) in adulthood. Over a median follow-up period of 12.8 years, 33,460 participants developed type 2 diabetes and/or cardiovascular disease.
Implications for Prevention
This study underscores the importance of maintaining a healthy weight from childhood through adulthood. It highlights the need for preventive measures not only for children currently experiencing obesity but also for those who are lean in childhood but at risk of becoming obese as adults. The findings advocate for a broader approach to preventive health measures, emphasizing the significance of healthy weight management throughout life to mitigate the risk of type 2 diabetes.
Conclusion
The research conducted by Germán D. Carrasquilla and his team provides valuable insights into the long-term health risks associated with changes in body size from childhood to adulthood. By demonstrating that individuals who grow from being lean in childhood to obese in adulthood have an increased risk of type 2 diabetes, the study calls for a more inclusive strategy in preventive health measures, focusing on healthy weight management across all stages of life.

Pers' achievements are a reminder that obesity and type 2 diabetes are multifaceted issues requiring a nuanced approach to treatment and public perception. His work continues to inspire and challenge the medical community to explore new frontiers in the fight against these chronic conditions.
Pers' research also aims to dispel several common myths about obesity and diabetes, which are deeply ingrained in the public perception and often oversimplify the complex nature of these conditions. Here are some of the myths his work addresses:
Myth 1: Obesity Is Solely a Result of Personal Choice
One of the primary myths that Pers' research challenges is the notion that obesity is simply a result of individual choices related to diet and exercise. His work emphasizes the significant role of the brain in regulating energy balance, glycemic control, and genetic predisposition to obesity. By identifying key cell populations in the brainstem associated with genetic obesity predisposition and the ability to control eating, Pers' research underscores the complexity of obesity beyond personal choice.
Myth 2: Obesity Directly Causes Diabetes
While obesity is a risk factor for type 2 diabetes, the relationship between the two is not as straightforward as often portrayed. Pers' research into the brain's influence on metabolic diseases like obesity and type 2 diabetes highlights the intricate biological and genetic factors at play. This challenges the oversimplified view that obesity directly causes diabetes, instead pointing to a more complex interplay of factors.
Myth 3: Simple Solutions Like "Eat Less, Move More" Are Adequate
The research by Pers also addresses the myth that obesity can be easily managed or prevented through simple solutions like reducing caloric intake and increasing physical activity. While these factors are important, Pers' work on the brain's role in obesity and diabetes illustrates that the underlying causes are multifaceted, involving genetics, brain function, and possibly other environmental and biological factors. This suggests that more nuanced and targeted approaches may be necessary for effective treatment and prevention.
Myth 4: Obesity Is Inevitable for Those Genetically Predisposed
Another myth that Pers' research helped to dispel is the fatalistic view that obesity is inevitable for individuals with a genetic predisposition. By exploring how specific brain cell populations influence the ability to control eating and energy balance, his work suggests that understanding and potentially manipulating these brain mechanisms could offer new avenues for treating or preventing obesity, even in those with a genetic predisposition.
Conclusion
Associate Professor Tune H Pers's groundbreaking research is challenging and reshaping our understanding of obesity and type 2 diabetes. By highlighting the critical role of the brain and genetic factors in these conditions, his work dispels several common myths and opens new possibilities for more effective treatments. This research not only advances scientific knowledge but also has the potential to change public perceptions and improve the lives of those affected by obesity and diabetes.

The U.S. Food and Drug Administration (FDA) has recently issued a safety communication regarding the use of smartwatches and smart rings that claim to measure blood glucose levels without piercing the skin. This warning, dated February 21, 2024, is a critical alert for consumers, patients, caregivers, and healthcare providers, emphasizing that no such devices have been authorized, cleared, or approved by the FDA.
The Risks of Unapproved Devices
The FDA's concern stems from the potential for inaccurate blood glucose measurements provided by these unauthorized devices. For individuals managing diabetes, precise glucose monitoring is crucial. Inaccurate readings can lead to serious errors in diabetes management, such as incorrect insulin dosing, which can result in dangerously low glucose levels, mental confusion, coma, or even death within a few hours.
Understanding the Fine Print
Interestingly, some advertisements for these devices may include fine print stating that they only display blood glucose readings from a continuous glucose monitor (CGM) that is already passing data to a smartphone. This distinction is vital as it implies that the smartwatch or ring itself is not measuring glucose levels but merely acting as a secondary display for data from an FDA-authorized device that does pierce the skin. This could potentially mislead consumers into believing the smartwatch or ring is independently monitoring glucose levels.
FDA Recommendations
The FDA advises against purchasing or using smartwatches or smart rings that claim to measure blood glucose levels on their own. Instead, consumers should consult with healthcare providers to select an appropriate FDA-authorized device. Healthcare providers are also encouraged to inform their patients about the risks associated with using unauthorized devices and to assist them in choosing a suitable FDA-authorized blood glucose measuring device.
Market Monitoring and Reporting
The FDA is actively monitoring the market to prevent the illegal marketing of these unauthorized products. They are also urging the public to report any problems with inaccurate blood glucose measurement or adverse events from using these devices through the MedWatch Voluntary Reporting Form.
Conclusion
The FDA's warning is a reminder of the importance of using medical devices that have undergone rigorous testing and approval processes. While the allure of non-invasive glucose monitoring is strong, the current state of technology has not yet produced a device that can safely and accurately perform this function without FDA approval. Consumers should remain vigilant and rely on approved methods for managing their diabetes to ensure their health and safety.
