Not true. If it was the Eskimos, Inuit and other people who lived in the Arctic circle before modernity encroached there would have been unable to survive. If you’re eating all lean meat you’ll have some kind of deficiency disease inside a month. If you eat fatty meat as well you’ll almost certainly get everything you need and if you eat organ meat as well as muscle and fat we know you can eat that for a year with no ill effects whatsoever.

How is it dangerous if you supplement Minerals?

Eat fatty meat including organ meats and you can eat nothing but meat for years with no ill effects health wise.

As soon as a diet requires adding supplements, it is no longer a diet that can be used for a lifetime IMO.

What danger are you referring to?
