If I get the time, I'll link the studies (if someone else has them handy or wants to dispute these claims, please do so): Strength and muscle mass do seem to be very good predictors for longevity. Lifting weights does seem to be one of the best ways to increase these two things. The acute effects on blood pressure don't seem to be problematic for healthy individuals and don't really cause a chronic increase in blood pressure. There's a lot of controversy over being vegan vs. being an omnivore, but it seems like the actual data on outcomes (read: not theoretical mechanisms) suggest that: 1. If you tell the average person to follow an omnivorous diet vs. telling them to eat a vegan one, even if you give them some basic guidance on how to eat healthy (try to stick to minimally processed foods, etc.), doing the latter does tend to improve various biomarkers associated with longevity. [0] for example, suggests this. 2. There's no clear case that this difference is caused by something other than differences in: a. Average caloric intake (meat-eaters tend to eat more calories, and very broadly speaking, more calories = worse health) b. Saturated fat (meat tends to have more saturated fat, which is associated with higher apoB, a big factor that contributes to heart disease) c. Nutritional opportunity cost (obviously, all else equal, eating meat means you're not going to be eating something else - for example, eating a lot of meat could mean you don't get sufficient fiber intake, which seems to have positive effects on health). That is, if meat-eaters controlled for these things - making sure they didn't overeat, making sure they didn't overconsume saturated fat (by, for example, eating leaner cuts of meat), and making sure they had a balanced diet, it's not clear that meat has some other detrimental effect. I think weight lifting being good for your health is relatively uncontroversial. The data does not really seem to suggest that meat in a balanced diet has detrimental effects, though the jury is still out. It might very well be the case that the vegan yoga trainer lives longer than the meat-eating weight lifter, but it would probably be a mistake to infer a causal relationship between an otherwise healthy diet with meat in it/weight lifting and lower life expectancy.
