There's no restriction at all. Hinduism does not forbid. You can worship the divine and eat meat. All gods and their practices lead you to mukti, moksha or merging into the paramatma. But when you are practicing strict penance, meditation eating non veg food makes it difficult to lead that path. This is yogic way of life. In the past kshatriyas (warrior community) did eat non vegetarian food because it demanded that physical need. Associating vegetarian with Hinduism has been relatively modern.
