Right now covid is number 27 in the rankings or cause of death, I wish people would put the same effort into their health when it comes to preventable diabetes and heart disease.

When I said we had different sources of information, I obviously underestimated the situation. For example, covid was the third leading cause of death in the US in 2020 alone (before we hit the 2021 peak), even though the US didn't start to get cases reported until Feb/March time frame, if I recall correctly (US data is probably one of the most reliable and easily accessible sources, so I am working from that, but I have no doubt you could find similar data for most first world countries).

I wish people would put the same effort into their health when it comes to preventable diabetes and heart disease. It would slash covid even more too as 70 percent of those who die of covid are overweight.

While you are certainly correct that being overweight is a strong contributor to risks from not only covid but many other health conditions, I think it will be difficult for most people in the short term to significantly lower their current risk from covid in this way. But longer term, yes, it would be great if people could manage their weight better. But realistically, it is also easy to see that this is very difficult for most people to do.
