To summarize, populations who diet and exercise, the same amount as populations in the 80s, are heavier. No one knows why, but some possibilities are - increases in chemicals in the environment - increased prescription drug use - increases in animal product consumption - changes in the human gut biome - proliferation of artificial sweeteners

Deliberate exercise is one thing, but maybe people today are more sedentary when they aren't exercising. It's my impression that physical activity required at many jobs is lower today than it was then. Following through to the actual study, it appears to have considered "leisure time physical activity" but maybe not workplace physical activity.

  Pontzer's book Burn seems to indicate exercise is good for health but not weight loss. Energy usage in the body is complicated but diet seems to be more important than exercise if I understand it correctly.

    Exercise also frankly just doesn't burn many calories. It only really takes two candy bars to undo two hours at the gym, calorie wise.

Surprised they didn’t mention smoking. Nicotine is an appetite suppressant.

Another possibility is that the data is just wrong. Subject reported data on diet and exercise is notoriously inaccurate.

  This. Absolutely this. A good friend used to lament about the data they were entering was of very poor quality. However the skews were somehow magically understood by the consumers of the data or maybe overall the day averaged out over time. Data cleansing is a thing no?

I have a very hard time finding edible chocolate. It is all sugar and cocoa. Want to buy some canned vegetables ? They contain sugar (why ?). Bread seems to contain more and more sugar. Want to buy semiprocessed food ? It has a lot of sugar. Want to buy some juice ? 10 -20 g of sugar per 100 ml. It is just crazy.
