In the upcoming Annual Meeting of the European Association for the Study of Diabetes, Professor Matthias Blüher will delve into the topic of metabolically healthy obesity (MHO). While a certain proportion of individuals with obesity do not exhibit the usual metabolic issues, the descriptor “metabolically healthy” could be inaccurate.
The term “metabolically healthy obesity” may, in fact, be imprecise, as even those categorized as such face increased health hazards. Factors such as fat storage mechanisms and the behavior of adipose tissue are critical in evaluating these risks, highlighting the significance of weight regulation.
During this year’s assembly of the European Association for the Study of Diabetes, the most recent findings concerning metabolically healthy obesity—commonly referred to by the lay public as “fat but fit”—will be examined. Professor Matthias Blüher, affiliated with the University of Leipzig and Helmholtz Center Munich in Germany, will clarify the criteria for defining MHO and query its designation as “healthy.”
Professor Blüher notes that approximately 15-20% of individuals suffering from obesity do not manifest metabolic complications commonly linked with this condition—such as irregular blood sugar levels, elevated blood pressure, type 2 diabetes, and other indicators of cardiovascular disease.

Gender Disparities and Fat Accumulation
Data indicates differing rates of MHO among men and women. Women with obesity are more frequently categorized as having MHO (7-28%) compared to men (2-19%). Conversely, about half of those living with obesity have at least two complications. When considering the same total body fat mass, individuals with MHO tend to have reduced liver fat mass relative to their Body Mass Index and total fat mass.
Professor Blüher will articulate that it is the performance of the adipose tissue in obese individuals, rather than their Body Mass Index, that establishes the presence or absence of MHO. In individuals with normally sized adipocytes, or fat storage cells, there is a reduced likelihood of obesity-related complications. On the other hand, those with enlarged and inflamed adipocytes are more prone to metabolic complications like insulin resistance.
The manner in which fat is stored appears to be a determinant in the classification of obesity as MHO. “Individuals storing fat internally, especially around organs like the liver, are significantly more susceptible to type 2 diabetes compared to those whose fat is more uniformly distributed,” Professor Blüher states.
Ramifications of Adipose Tissue Malfunction
Professor Blüher further explains that dysfunctional adipose tissue can result in tissue damage, fibrosis, and the release of proinflammatory and adipogenic molecules that eventually contribute to end-organ harm. For instance, adipokines, hormones released by fat, can directly impact vascular cells, potentially causing atherosclerosis. Moreover, fatty acids could compromise the functionality of liver or insulin-producing cells in the pancreas.
Assessing the Health Implications of MHO
Addressing the central issue of whether MHO can be genuinely categorized as healthy, Professor Blüher will share that multiple studies indicate that, when compared to individuals of standard weight with no metabolic issues, those with obesity but without metabolic comorbidities have a 50% higher risk of coronary heart disease. “Thus, even those termed as having metabolically healthy obesity still carry a residual elevated risk,” he adds.
In summary, some individuals with obesity do not show cardio-metabolic issues at a given moment. Previously, the diagnosis of MHO often led to deprioritizing obesity treatment. This viewpoint is now being reconsidered, as emerging data implies that the term “metabolically healthy obesity” is not entirely accurate. Professor Blüher concludes: “Regardless of the absence of additional cardio-metabolic risk factors, increased fat mass and dysfunctional adipose tissue still elevate the risks for type 2 diabetes and cardiovascular diseases. Hence, recommendations for weight loss and weight management continue to be crucial for those classified as metabolically healthy obese.”
Frequently Asked Questions (FAQs) about Metabolically Healthy Obesity
What is the main topic of discussion in the upcoming Annual Meeting of the European Association for the Study of Diabetes?
The main topic of discussion is “Metabolically Healthy Obesity,” led by Professor Matthias Blüher. The session will explore whether this classification is accurate and what it means for those labeled as such.
Who is Professor Matthias Blüher?
Professor Matthias Blüher is affiliated with the University of Leipzig and Helmholtz Center Munich in Germany. He is an expert in diabetes and metabolic health and will lead the discussion on “Metabolically Healthy Obesity.”
Is “Metabolically Healthy Obesity” a misleading term?
According to Professor Matthias Blüher, the term may be misleading. Even those categorized as metabolically healthy obese face elevated health risks. The session will explore the nuances of this classification.
Are there gender differences in the prevalence of Metabolically Healthy Obesity?
Yes, data suggests that women living with obesity are more likely to be categorized as having Metabolically Healthy Obesity (7-28%) compared to men (2-19%).
What factors determine whether an individual’s obesity is “metabolically healthy”?
Factors such as adipose tissue behavior and fat storage mechanisms play crucial roles. The manner in which fat is stored, particularly around internal organs like the liver, also influences metabolic health.
What are the health risks associated with Metabolically Healthy Obesity?
Multiple studies indicate that individuals with obesity but no metabolic comorbidities have a 50% increased risk of coronary heart disease. The dysfunction of adipose tissue can also lead to other metabolic complications.
What is the significance of adipose tissue in Metabolically Healthy Obesity?
Adipose tissue behavior is a key determinant in the classification of obesity as metabolically healthy or not. Dysfunctional adipose tissue can contribute to end-organ damage and metabolic complications.
Should weight loss still be recommended for individuals classified as Metabolically Healthy Obese?
Yes, despite the absence of other cardio-metabolic risk factors, increased fat mass and dysfunctional adipose tissue contribute to a higher risk of type 2 diabetes and cardiovascular diseases. Therefore, weight management and recommendations for weight loss remain important.

Wow, I never knew Metabolically Healthy Obesity could be so complex. Blüher’s insights are eye-opening. Makes you think twice about labels, doesn’t it?
so even if you’re classified as MHO, you’re still at risk for heart diseases and diabetes? That’s concerning. Time to reconsider my lifestyle, I guess.
Honestly, I thought being metabolically healthy meant you’re generally ok, even if obese. Guess I was wrong. This is a wake-up call.
What’s the point of giving obesity a ‘healthy’ tag if you still have to lose weight? Just makes ppl complacent imo.
Adipose tissue behavior, huh? never heard of that before. But now it seems crucial. Just adds to the already complex issue of weight management.
Matthias Blüher’s work is always so detailed. His sessions are a must-attend for anyone interested in diabetes and metabolic health.
the gender difference is interesting. Wonder why more women fall under the MHO category compared to men.
Why do we even have terms like “metabolically healthy obesity” if they’re misleading? Seems like the medical community needs to get its terminology right.
