I find that once I eat minimal sugar for a while, it tastes too sweet when I have some again. It's like a drug that you get used to and don't even realize how much you are eating anymore until you don't have it and see how darn strong it really is, so I am going to try to cut it out except for berries and summer veggies for the next few months and see how it goes.
I had researched that simple carbs turn into sugar very quickly in your body, but I hadn't realized that all carbs eventually turn into sugar. So the keto thing is about basically getting off of almost all sugar and burning fat instead. It seems pretty drastic, but I think it will be a wake up call to me that probably the reason I don't lose weight and am so good at gaining it is that I am still basically addicted to sugar mostly in the form of having too much of the complex carbs. Actually after making more snacks with nuts and cutting down on the carbs slowly, I am noticing how brown rice and the complex carbs taste pretty sweet to my taste buds. Nutrition is so surprising!
