Best choice I ever made! Once you try it you really wont want to go back to old eating habits. Its hard to explain but your taste buds change and food you crave no longer tastes the same. Ever once in a while you feel like something "bad" but then its like "really didn't taste that good!!"
I've been doing Keto since last October. I am at 112 pounds lost total, and 95 since I started Keto. I mostly like the diet. The only think that sucks is that so many restaurant foods are packed with carbs, even those that aren't obviously carb-laden. I mostly am fine with the diet. I plan to go "hard core" for a year, and then transition to a low-moderate carb diet if my blood glucose can tolerate it.
