If you’re still not in ketosis, and you’ve eliminated the likely causes of extra carb, here are some things you might want to consider looking into:
Are you eating too much protein? Excess protein is transformed into glycogen and keeps your body in glucose burning-mode.
Are you eating too many carbs? The amount of carbs that will put and keep you in ketosis in an individual matter and you’ll may have to experiment a bit to find your individual “sweet spot”.
Are you tracking your intake – it’s hard to guess the difference between 5g and 10g, to be sure you need to weight and measure.
