I’m noticing my blood sugar rises from about 5.5 to 6.5 between 3 a.m. and 7 a.m., and then increases another 0.5 to 1.0 in the first couple of hours after I wake up. I’ve found that avoiding breakfast foods like fruit and cereal — and instead eating eggs, meat, and vegetables — helps keep my levels more stable. About an hour later, I can eat fruit without causing a spike.
