Hypoglycemica with IF and low carbs

Answered on August 19, 2014

Hi guys. I've been following a cheat mode protocol of <20g carbs before working out in the aftenoon with ~80g carbs with dinner for the past few weeks. I do crossfit 4x a week and generally fast every morning. Today there was a free blood pressure measurement and blood glucose at the cafeteria so I gave it a shot after I finished my low carb lunch. My blood pressure was 118/68 which is fine but my blood sugar reading was 36. I was told that this is incredibly low. Is this just because my body has almost entirely adapted to burning fat during the day or do I need to up my carb intake at night? I have been attempting to cut for the past few weeks so that might have something to do with it.

IF only improves insulin resistance in males...in females it does the opposite

I don't know what IF would do, but it screws me up at the moment. 2 years ago I did pretty well while eating only in the evening, so I just might be too unhealthy at the moment to tolerate it.

Vivian, IF if anything should do the opposite.. restoring insulin sensitivity. Especially during longer fasts.

From what I've read, IF improves insulin sensitivity.

Wow, that's even lower than mine which has been around 54-64 during fasting. You should get a glucose monitor and take several dozen readings over a period of time to get a solid picture of your glucose levels.

A ketogenic diet shouldn't cause hypoglycemia, the reverse in fact. Ketosis is your metabolism's way of protecting against hypoglycemia - switching it's fuel supply from glucose to fatty acids and ketones.

As a diabetic, I can tell you that the hand-held BG monitors are very unreliable. Are you sure that it was 36 and not just a false reading?

If you really did get a 36mg/dl, then it's something to be concerned about, because that is well into "hypo" territory. Some people run naturally low BG scores, but <36 sounds dangerous. How were you feeling?

I too have low blood sugar and to prevent it by eating some protein every 3 hours. Poof! Blood sugar level remains in normal range as a result.

I'm really interested in this answer as well.... I suspect your blood sugar can be low and yet you (and I and others) feel fine because we're fat adapted and using ketones. I IF from 7pm to 11 am most days and eat VLC (20 grams or below)

Yes this was happening to me as well...don't go so long between meals you do not want to become insulin resistant. I do well with 14 hours but yours will probably be longer since you are male.
