Weight management is often treated as a "middle-age" problem, but new research suggests that the pounds you pack on in your 20s may be the most dangerous of your life.
A massive study of more than 620,000 individuals found that the damage from early weight gain is disproportionately high and surprisingly permanent. According to the findings, the younger someone is when obesity sets in, the higher the risk of early mortality.

The study, published in the journal eClinicalMedicine, analyzed data from the Obesity and Disease Development Sweden project.
"The most consistent finding is that weight gain at a younger age is linked to a higher risk of premature death later in life, compared with people who gain less weight," Tanja Stocks, a professor at Lund University and one of the researchers behind the study, said in a press release.
Developing obesity between the ages of 17 and 29 was linked to a 70% higher risk of early death compared to weight gain later in life.
Weight gain later in adulthood, between ages 30 and 60, was also linked to higher death rates, but the connections were generally weaker.
