How do some people stay normal weight in their 40s, 50s, even 60s?

This is what I don’t understand. I’m not overweight however I have definitely gained some weight since I was a teen (22 now) and I can see myself gaining more soon. Meanwhile my parents are 59 and 63, neither have been overweight at all in their entire life.
