Weight loss in 50s can restore heart health comparable to maintaining a healthy weight

Losing weight in one's early to mid-50s can significantly improve heart health, bringing it to a level comparable to those who have consistently maintained a healthy weight throughout adulthood, according to new research. By the age of 62, individuals who lost weight in their 50s demonstrated similar cholesterol levels, blood pressure, and inflammation markers as their peers who remained at a healthy weight, indicating robust heart health.

The study, which analyzed data from over 6,000 participants in the UK's National Child Development Study, tracked participants' body mass index (BMI) from their 20s onwards. Researchers noted the highest weight each person reached by age 42 and then examined weight changes by age 50 and 55.

Cardiometabolic health, a measure of the heart and metabolism's well-being, is crucial for preventing conditions like heart disease and heart attacks. The findings revealed that while individuals who maintained a healthy weight throughout their lives exhibited the best cardiometabolic health at age 62, those who were overweight but lost weight in their 50s showed a remarkable improvement.

Conversely, participants who remained overweight, gained weight, or experienced significant weight fluctuations had poorer cardiometabolic health. The study highlights that even a modest weight reduction in middle age can have a substantial positive impact.

Dr. Charis Bridger Staatz, the lead author from University College London's Centre for Longitudinal Studies, emphasized that health decline is not an inevitable part of aging. "A modest reduction in weight in people's 50s may make a real difference to their health, potentially improving their quality of life and reducing their risk of heart issues," she stated. Dr. Staatz also suggested that obesity prevention efforts should extend to individuals in their 50s, in addition to focusing on children and young people.

Co-author Dr. Laura Gimeno supported the findings, noting their relevance to current discussions about expanding access to weight-loss support, including medications. "They also highlight the importance of reducing further weight gain in midlife, as this was consistently linked to the fastest deterioration in heart health," she added. Policymakers are encouraged to consider how weight management support can be offered proactively, potentially leading to long-term benefits for healthcare systems by reducing the need for services related to heart and metabolic issues.
