Prior to LCing I had hypoglycemia for 25 years.... and I do NOT recommend sugar at all...it gave me the heebie jeebies just thinking about carrying around a tube of cake icing!! But I guess everyone is different!

I always had a protein source nearby.... peanut butter, nuts, cheese, milk, and of course, meat! If carbs are the only thing available, then a protein portion should be eaten within an hour. And absolutely it is important to eat several times a day.

Caffeine seems to trigger an insulin response in me, so I try not to consume too much of that. If I have caffeine with a meal, it's not as bad.

All carbs ingested should be good, high quality carbs, no simple starches.

That's my best advice right there.
