> This makes sense as things like bread, if left in your teeth, eventually turn to basically sugar, and start working to dissolve your teeth.
This was in the early days of keto, back when you couldn't find any keto products at the store and it was just a small subreddit that spread by word of mouth.
I described my diet to my dentist (no carbs at all, no sugar, lots of green veggies, healthy meats and fats, all home cooked), and she instantly approved of it.
IMHO Keto has gone off the rails, no true scotsman and all of that. In the early days keto shared a lot of dietary stuff with paleo in regards to no processed ingredients, everything from scratch, and I think that made a real difference in how effective it was.
Before if I wanted keto ice cream I had to make keto ice cream. Now I can just buy it at every local grocery store. Well excess calories are still excess calories...
Also the prepackaged keto stuff isn't as satiating as from scratch keto food, and half of the benefit of keto is the food is supposed to be more satiating.
