Essentially, you really can't overdo it on protein if you're low-carbing to bring on constant ketosis. It's just really hard for most people to get "too much" protein in any way of eating.
(The comment about keto being unhealthy is an opinion, try to ignore it. The truth is that everyone goes into ketosis - not keto-acidosis - about every night. It's just a state of burning fat as energy.)
In most diets in which ketosis is the goal, fat & protein are your friends - they help the metabolic engine to stay going. Are you following a specific plan that's restrictive of fat, protein AND carbs, or making it up as you go?
