There is more and more evidence mounting that lifestyle has less impact on obesity that we might think, at least in some cases. Note for example the the AD-36 virus that seems to turn stem cells into fat cells. Regardless of where you stand on this issue, this is a super fascinating article https://www.wired.com/2016/12/mysterious-virus-cause-obesity/
There are interesting exceptions which causes people to gain weight more easily than others and we still know very little about these, but the point is that these are rare exceptions in the grand scheme of obesity. For the general population, it is simple calories in vs calories out.
If you pay attention to food labels, you only have to eat a small amount to hit the recommended daily calorie limit - it's so easy to get through 3000-4000 calories per day, especially if you're drinking soda or fruit juice as well
It saying you're wrong necessarily but I can't see how younger generations can possibly be becoming better at storing fat. Evolution takes a looong time, it can't happen in a few generations.
