It's for sure not the "reverse", even if for some people with certain diseases the benefits may outweigh the risks. It's undeniably linked to certain cancers and arteriosclerosis
It's actually the reverse. "some people" is every person that is overweight (50% of USA). "cancer" are studies where it includes other things, like fast food etc. Haven't researched arteriosclerosis, but we'd have to see studies being done on healthy patients with strict keto/carnivore and not dirty diet.
