I am type 1 and on novorapid and lantus . Also lchf diet. I also run typically 3 to 5 miles 2 to 3 x a week. Since starting low carb I tend to get night hypos on run days no matter what time of day I run. My Bgs are usually in the 7 to 8mmol/l before running and sometimes peak at the start of the run then drop towards the end of the run to 4 to 6 mmol/l and i feel great running with these levels. I dont tend to change my meals or doses as they are stable right up until 2am when they can suddenly drop to 3mmol/l or lower. The hypos wake me and I correct with 100mls Lucozade which can see me through until morning or I may need to have another 100mls Lucozade at 5am if bg' s plummet again. My overal carb intake is prob only 50g a day. Generally I feel the healthiest I ever have Just wondered if anyone else on lchf diet has similar issues and what you do to stop these night hypos happening?
