I include yogurt and cheese in dairy. They will put fat back on your body.
I'm not advocating for yogurt and cheese; just being honest about what I ate back then. I was eating roughly 4000 calories a day just to maintain weight with very little fat on me so I could afford it easily. And in the mid-70s, my diet was pretty radical. I wasn't hearing people say "you shouldn't eat dairy". What I heard was "you need meat to supply protein to maintain your muscles".
