I will say that for me, breaking the carb addiction was key to weight loss and feeling better.

You can go keto-only or some other diet or a fast, but being able to go through a period of time with a low amount of carbs, and then realizing how crappy I felt after a typical high-carb meal, really helped me stick to a lower-carb diet.

But can I also add, "only in America" would you have a place where you pay exorbitant amounts to drink only water and you stay there.

However did monks and gurus manage without it?
