I bought some ketones sticks the other day at Costco (7.00 for 50 strips). I have been checking my level every morning and it shows I am in full ketosis. I am keeping my carbs low and 9 days ago started taking a tbsp. of MCT oil in the morning and one in the afternoon. Since then I am down 5 pounds . I am not sure how accurate they are,but something seems to be working .
