Effective preventive measures must be taken to address the obesity pandemic and reduce the risk of noncommunicable diseases. This includes health promotion initiatives such as promoting healthy lifestyles and increasing access to healthy foods and physical activity programs. Education is also key to ensuring that individuals understand the importance of staying fit and healthy.
Our β€œLiMa” (Lifestyle Matters) project uses a multidisciplinary approach aiming to examine the systemic and tissue-specific effects of obesity-related type 2 diabetes. This integrative approach has been in operation for more than a decade, providing novel insights about the underlying role played by each tissue in obesity-related pathophysiology and its progression. Significantly, we have found that obesity leaves a lasting β€˜metabolic fingerprint’ in adipose tissue even after a successful restoration of a healthy state through a diet and exercise intervention. This metabolic memory was observed particularly in visceral fat, where mitochondrial performance was compromised as suggested by permanent alterations in mitochondrial transcripts and proteins, a functional decay, and a significant loss of mtDNA (1). Interestingly, no major impact was evidenced on the subcutaneous depot, which implies a further step towards shedding light on the complex relationship between adipose tissue and metabolic disease.
We urge to validate the translational value of our preclinical model, since it could have an evident economic impact. It would enable earlier diagnosis and tailored interventions, reducing costs, improving patient outcomes, and providing new biomarkers to assess treatment success. This could be a game-changer for obesity and associated diseases.
