Can you still stay in ketosis despite eating a higher than normal carb amount on one day? Example, say you normally eat 30 carbs (and you don't know your limit) daily and one day you eat 80. You test yourself that day, the next day, 36 hours later, and you are still in ketosis....

a) Does that mean you can safely consume more carbs (to maintain, not lose) weight?

b) That the carbs you consume (not all carbs are equal) do not knock you out because they may not be from sugar?

c) Does FLOUR carbs knock you out or are potato, rice, bean carbs worse?
