Been for a mountain bike ride today and felt awful from the off. Couldn't keep up with guys that normally have trouble keeping up with me! Half way round was sick so came home early. Checked bs.... 7.0 (happy with that) checked Ketones.....2.0 (happy with that) heads thumping, feel a bit dizzy and nauseous. Ketone levels have been as low as 0.2 and as high as 2. Is this normal? Once in ketosis do you naturally stay in ketosis (obviously keeping carbs low) or do you drift in and out depending on time of day, amount of exercise etc. Having read about symptoms of low carb flu and having suffered it slightly when I first started could I be going through it again?
