On an individual level the study shows why some people are more prone to weight gain than others. But there's been an epidemic of obesity over the past few decades, and there's no reason to believe people's gut flora changed over that period. Even if it did, there must have been an underlying cause.
What has undoubtedly changed are people's lifestyles:
(1) Less smoking. (This is a good thing, but it has resulted in weight gain.)
(2) More driving and less walking/bicycling.
(3) Children playing games on computers instead of outside.
(4) More sitting at desks, and less moving about, at work.
(5) More eating out.
and probably a few other factors.
- therealdrag0 11y agoYep. Lifestyle change without dietary change. I'm M27 6' 150lbs and mostly sedentary; calorie recommendations for me are 2300+. Last time I counted my calories I was eating closer to 1600. My weight is maintained and I experience no lack of energy compared to peers. I think people over estimate the amount of food they "need" and over estimate how many calories are burned for x-amount of activity.
- Shorel 11y agoThe amount of fat free and fructose sweetened food I just saw in the supermarket today seems to be a factor too.
