Depends on who you ask, but in olden times, and India has a lot of antiquated values, but again, depends who you ask.

If you're upper middle class and fat in America, you usually are actually lax in your dietary habits. However, you can also be a poor or lower/lower middle class person who has issues with maintaining preventive care, like working receiving in retail or two jobs in the service industry and work hard, but have no knowledge of good dietary practices, and/or time to prepare good food, and that shows as obesity. The high cost of inflation from greedy corporations and lack of basic food items due to logistical issues not helping poorer Americans.

It does actually make sense. Because in those other countries(and you'd have to be specific, because different countries have different factors), people can forced into usually high intensity farm work/manual labor which can offset the obesity, but not the hypertension, as even athletes can suffer from that. Renal failure brought on by lack of preventive care for the poor and working poor is also a problem as well. So lack of preventive care and the ability to take off work to get that care, lack of resources to have a balanced diet and time needed to make good meals, the terrible infrastructure in black neighborhoods that have tainted drinking water. So there are many factors one has to look into that, if one is just looking for confirmation bias to win an Internet argument, rather than what constitutes a focus on the cause and a solution to the problem, then we reach an impasse.
