Let us imagine that starting tomorrow every single American is granted infinite endless and free access to anything available at any restaurant or grocery store or other food service. Do you think that in 10 years the obesity epidemic would be: better, same, worse?
I have trouble imagining that it would be better. Look at people who come into access with large sums of money for reasons outside primarily mental achievement - athletes after leaving pro sports, musicians after they stop performing, actors after they stop acting, lottery winners, and so on. Some quick searching turned up articles like this [1]:
"The researchers found that the athletes' weight held steady for over 100 years, with the majority of them weighing in at what is considered "normal," -- i.e., with a body mass index (BMI) between 18.5 and 24.9. However, around 1991 the average player's BMI began to rise, and over the last 25 years nearly 80 percent of players fall into the overweight or obese category with a BMI above 25. "
There's a strong correlation between socioeconomic status and obesity, but that doesn't mean it's causal. Obesity is primarily driven by a lack of impulse control. If you force yourself not to over-eat, you could live off of even McDonalds without becoming obese.
Good science always leaves the door open to alternative explanations, even when it may be unlikely. In this case the researchers were relying on BMI to measure obesity. BMI doesn't account for musculature. To not even consider this possibility would be the domain of agenda-driven research, which this paper clearly was not.
Here is a link to the actual paper [1]. Their concluding statement was:
"Professional athletes are not immune from the
growing obesity crisis and may not provide optimal role models of health. Concussions have drawn
attention to overlooked long-term health consequences of sport participation. Increasing body
mass in professional baseball players warrants similar attention for its potential impact on long-term
morbidity and mortality because these players hold
a special place as role models of health and human
performance in our society."
Spot on. BMI is a bad indicator of individual health and fitness. I have a BMI of 25 right now but that’s because I added 14lbs of muscle over the last year while dropping a couple pounds of fat. Body fat percentage sitting at 18%.
Now, there are lots of big boys in the NFL that definitely have a couple extra pounds on them, which could also be skewing numbers.
It would be an accelerant for sure, but maybe there would be a self-selecting correction: people with no self-control over food intake would just die out over the centuries (assuming there are genetic and cultural factors involved in food intake south control).
