A new study published in the Journal of Gerontology has found that maintaining a stable weight is linked to greater longevity in older women. The study, led by researchers from the University of California San Diego, examined the weight variations of 54,437 women enrolled in the Women’s Health Initiative. The study found that women over the age of 60 who maintained a stable weight were more likely to live to the age of 90 or older.
The study defined weight stability as having less than a 5% variation from baseline weight. Women who lost 5% or more of their weight, especially if it was unintentional, were less likely to reach the age of 90. On the other hand, gaining weight was not associated with exceptional longevity.
Dr. Shara Cohen, Founder and Director of Cancer Care Parcel, suggested that there could be several mechanisms behind this phenomenon. A stable weight may indicate a well-balanced and consistent dietary pattern, as individuals who maintain their weight are more likely to follow a diet that provides essential nutrients and avoids extremes in caloric intake. Nutritional stability can have a positive effect on metabolic health, reducing the risk of chronic diseases that can contribute to longevity.
In addition, a stable weight may indicate an active lifestyle. Regular exercise not only helps with weight management but also enhances cardiovascular health, maintains muscle mass, and supports overall bodily functions. Engaging in physical activity can counteract age-related muscle loss and metabolic decline, promoting a longer and healthier life.
Mary Sabat, a Nutritionist and Ace Certified Trainer, provided strategies for older women looking to maintain a stable weight for a longer and healthier life. These include consuming a balanced diet consisting of whole foods, engaging in regular physical activity, practicing portion control, managing stress, staying hydrated, getting regular check-ups, getting good sleep, and seeking out social support.
Overall, this study highlights the importance of maintaining a stable weight in later life for increased longevity in women. Diet, exercise, stress management, good sleep, and social support all play significant roles in weight management and overall health. By incorporating these strategies into their lifestyle, older women can increase their chances of living to be 90 and older.
