IME, traditional German cooking is often quite healthy, at least the homecooked stuff that I’ve seen (mostly in my own family). Of course the meat portions are usually too big, but there’s typically big portions of vegetables and cooked potatoes aren’t unhealthy, either. Even Döner is fine if you go easy on the meat and sauce - it’s basically a salad! Main issue is portion control, eating what’s basically fast food like schnitzel with fries instead of schnitzel with potatoes and sauerkraut, and all the other stuff that people eat in a day (sweets, snacks, booze, bread with fatty cold cuts, cheese and tons of butter).

Too bad I hate the taste and texture of boiled potatoes and most of the traditional vegetables!
