Dr. Berg talks about keto and dairy. The ketogenic diet requires you keep your carb low and especially sugars down to zero. Yogurts are out – because they contains lots of sugar, even the plain has 10 grams of sugar. Milk is pretty high – 12 grams sugar, but cheese, certain cheeses are zero sugars, but in general cheese is okay because it has very low sugar except for processed cheese, which is crazy high – 19 grams. Half and half is fairly low and whole cream is even better.
