Evidence of all these impacts is easy to find. Here's just one link about the increased rate of childhood obesity:
This kind of argument is exhausting. You said that excess deaths are confounded with obesity. I said that if they were, it would be comparatively easy to measure, so I suspect your hypothesis is simply wrong. Then you came back with a number that showed weight gain among kids, which I didn't try to refute.
Your hypothesis is a Big Thing. You're saying people are dying in very large numbers (millions a year), from existing syndroms that we have been tracking for decades. And... somehow epidemiologists are silent on that? It seems suspicious, you agree, right? Isn't the Occam's razor take is that you're simply wrong here, and that people are dying from a pandemic and not obesity?
