Early-Adult Weight Gain Linked to Higher Lifetime Mortality, Study Finds
A Lund University study followed more than 600,000 people from age 17 to 60 and found that obesity onset in early adulthood (17–29) was linked to about 70% higher all-cause mortality during follow-up, driven largely by cardiovascular disease. The findings suggest the duration of obesity, rather than late-life weight gain, may drive risk, potentially via long-term insulin resistance and inflammation. Exercise and diet data weren’t analyzed, and there are sex-related nuances; the takeaway is to aim to prevent obesity early in life.
