Enhancing Heart Health and Aging Gracefully with Weight Loss and Diet
Exciting research underscores the benefits of a multifaceted lifestyle intervention that combines an energy-restricted Mediterranean diet and regular physical activity, significantly improving cardiovascular health markers and reducing aging in immune cells. Participants following this regimen not only experienced enhanced functionality of HDL cholesterol—vital for removing excess cholesterol from arteries—but also showed reduced signs of aging in their immune system, specifically in T cells, which are crucial for immune response.
The intervention focused on practical lifestyle modifications, including dietary adjustments and increased physical activity, which collectively contributed to these health improvements. Particularly notable was the decrease in senescent T cells, cells that have stopped dividing and can contribute to age-related diseases, highlighting the potential of diet and exercise in reversing certain aging processes and promoting a healthier, longer life.
This research could pave the way for targeted dietary and fitness strategies that bolster longevity and reduce the risk of cardiovascular diseases. The findings are promising for those seeking to improve their health through manageable changes in their daily habits, offering a blueprint for aging healthily while maintaining heart health.

Abstract
Objective: Life expectancy and obesity prevalence are increasing worldwide, leading to an increase in the prevalence of cardiovascular disease. High-density lipoprotein (HDL) functionality and immunosenescence play key roles in cardiovascular disease, longevity, and quality of aging. Both molecular hallmarks of aging are impacted by obesity and metabolic syndrome and can be modulated by lifestyle. We aimed to evaluate the effect of a lifestyle intervention focused on an energy-reduced Mediterranean diet (erMedDiet), physical activity (PA), and behavioral support on HDL cholesterol efflux capacity (CEC) and immunosenescence.
Method: CEC and immunosenescent T cells were determined in 60 participants from the control group (CG) and 56 from the intervention group (IG) of the PREDIMED-Plus trial at baseline and after 1 and 3 years of follow-up. PREDIMED-Plus is a randomized, controlled, parallel-group trial with an IG of erMedDiet, PA promotion, and behavioral support for weight loss and a CG of usual primary care advice. The sample included 116 volunteers from the PREDIMED-Plus-IMDEA subsample of the PREDIMED-Plus trial. Men aged 55 to 75 years and women aged 60 to 75 years with a body mass index between 27 and 40 kg/m2 and metabolic syndrome were included.
Results: Participants within the IG had significantly improved CEC (2.42% and 10.69% after 1 and 3 years of follow-up) and a decreased in senescent T cell profile (-3.32% ± 12.54% and -6.74% ± 11.2%, p < 0.001, after 1 and 3 years of follow-up). Baseline obesity status impacted the response to the intervention.
Conclusions: A weight loss intervention program with erMedDiet and PA ameliorated senescence markers.
