I have been on a keto diet for exactly one month. I don’t have diabetes or anything. I just need to lose about 100 pounds. I am 30 years old and female. Before I started keto, I had a complete blood test at my donctor’s office and my fasting glucose level on a high carb diet was 81 mgr/dL.
I started with ketostix in the beginning and they would sometimes turn medium purple and sometimes show me out of ketosis. So I got myself a blood ketone meter and have been testing for 3 days now. My blood ketone levels were 0.0, 3 days ago, despite consuming less than 50 gr of carbs. My blood glucose levels after lunch on the first days were 81-83 mgr/dL.
I reduced my carbs to less than 20 gr for two days and today, the highest reading I got was 0.4 mmol/L I later started feeling very jittery, cold and without energy so I measured my BG and it is hovering around 62-65 mgr/dL apparently and my ketone levels have again dropped to 0.2 mmol/L (several measurements show the same).
What is happening? I am not losing weight either if that is of any interest. I am not hungry at all and I am down a whole dress size since I started.
Additional information: I have been on a keto diet twice before. Once in 2016 and once in 2018. Of course I had only ketostix back then and despite eating more than 50 gr of carbs, I lost about 20 lbs each time within 2-3 months.
I weigh everything I eat and log it into MFP app, about 1500 kcal. I don’t now what’s happening. I feel so faint and miserable right now that I am considering eating some carbs. I once fainted in the shower on a 24 hour fast despite drinking enough, so I am a bit scared that might happen again.
Any suggestions and advice would be much welcomed.
