I have been doing keto for about a month and am doing great . My ketone levels were rising nicely and were reading right around 1.4 four days ago . I took my blood ketone readings the last 2 days and it was reading between 0.3 and 0.9 . I have done nothing different and cant figure it out !
Could it be possible my blood ketone monitor needs to be re-calibrated ? I was doing keto for months about a year ago so it has been used quite a bit .
