There are couple of things I just wanted to mention to you.

You may still be losing weight if you keep your carbs low enough and your sticks may not read ketosis but that is ok.

You chose one of the highest carb veggie to start with. Here is a list of Atkins Induction veggies to try again. I'm a little anal about this but I know veggies are so important to good health and natural fiber is so important in weightloss too.

Atkins Induction Allowed

Please try one of the higher fiber veggies that you are allowed to have up to 2 cups daily even with minimal carbs in your diet.
