My favourite food is meat. I love all sorts/kinds of mea (OR I love all meat) t: pork, chicken, beef, rabbit, turkey, duck... In one year(365 days) I eat meat like 300days(something like that, maybe 310). It's delicious and very healthy. If you work out, meat is the best protein for you. Have a nice lunch.
Instead of "I eat it like 300 days, it's better to say "I eat it approximately 300 days a year" or "I eat meat almost every day"
the word "meat' is uncountable in English, so you can't say "all of them"
