Since ketones are the byproduct of burning fat, I'd say ketosis is very important. I'm not sure where you are having a problem. You've lost 3 pounds in 5 days and apparently you are losing inches (love handles) too. Are you concerned that your lack of exercise will keep you from achieving ketosis? Walking will use up your glycogen stores too. I read somewhere that it takes 30-45 minutes of brisk walking to do that. Also, you won't be storing as much glycogen since you have cut the carbs it is made from.
Sounds to me like you are doing TERRIFIC.

Have a great day,
Mary
