The modern 'getting fatter' trend is more about less healthy foods, and good-tasting, but very unhealthy foods being much more convenient than healthier choices. If you only have to rip open a bag, or microwave something a few minutes to eat, that's what most will do. By comparison, baking, or frying something on the stovetop requires more time and effort.
Also, overall stress has turned eating into a recreational activity. Whereas in times past, people at regular healthier meals at fixed times, now people are eating at irregular times, and out of the desire tof eel good moreso than simply replenishing the body's energy source.
Also, our sedentary lifestyle isn't giving us the exercise we used to have. Most jobs now don't involve much in the way of physical exertion. If getting exercise involves joining a healthclub or gym, there's a massive deficit of physical activity in the person's life. Rather than walking to and from work, then doing physical labor there, we drive, then sit most of the time. And even those that do walk and exert themselves on the job, are then eating high sugar/salt/fat foods instead of healthier foods prepared in the kitchen.
Lastly, modern processed foods are deliberately formulated with 'sweet spots' of fat, sugar, and salt to be more delicious. But these scientifically formulated treats are producing a narcotic-like effect in our brains making the consumption of more and more of them likely to occur. And rather than triggering in the brain the 'I'm full' reaction with less consumed, they're producing the exact opposite so we only feel full when our stomachs are literally filled to capacity. And instead of having anything in the way of nutritional value, most all of it either becomes fat, or is expelled from the body.
Good rule of thumb I abide by is 'if it comes in a bag it's not food, it's chemistry.'
I tend to think though, that these men are happy with their wives because their wives are happy with themselves.
