No, but on a higher meta-level it is contagious. Obesity is more prevalent in societies where high-caloric foods are more readily available. Now I'm more libertarian leaning myself so I wouldn't actually advocate for this, but if we mandated a cap on calorie-per-serving for "foods", you'd see a drastic drop in the availability of high carbohydrate foods (particularly sugar) which would essentially cause forced sugar-withdrawal in most of the population.

A couple months later? Everyone's sugar-thermostats are reset, the lower-calorie food tastes nearly as good – if not better – and obesity rates would plummet.

However, since we don't/can't coordinate such a thing on a national level, everyone gets exposed to constantly increasing carb content in their food, and maintaining a lower calorie diet requires significantly more effort. I can speak from personal experience, I simulated this on a personal level when I moved to South Korea for 2 years where sugar is nearly non-existent. As a modestly thin person I lost an additional 15-20 pounds while I was there without having to work hard or suffer with worse-tasting food (well, I did experience sugar withdrawal for the first couple months).

Quoting the NYT for anything related to Israel is likely biased.

No matter what one's stance is on Israel, or the Palestine question, it's hard to blame the actions of one company on the Israeli government.

I should have clarified NSO group. They are an Israeli company with many ex members of Israeli NSA (whatever it's called).
