Keto-Vegan?

Is this possible? I’ve been vegan for years but I’m prone to hold more weight with a higher carb diet. so I’m really interested in Keto because of this. (I’ve had genetic testing done so I know for a fact i’m more susceptible to weight retention on high carb) can I sub in tofu/seitan instead of meat and use nut milks instead of dairy etc...? it’s hard..I want to get in shape and feel good but I cannot bring myself to eat animal products. Also I’ve been avoiding cooking with much oil but it seems like oil is a big part of Keto diet? Has anyone tried eating Keto-vegan? Any help or thoughts would be great
