I also suffer with low blood sugar and have for awhile. I went to see a nutritionist last year and she had me eat six small meals a day. Every meal I ate had to have protein in it. Here is an example of a day.
Breakfast: 2 eggs and oatmeal
Snack One: small piece of grilled chicken with brown rice and a vegetable
Lunch I normally pack what is left over from dinner. So for example, if I had spaghetti I would eat a green vegetable and piece of chicken
Snack Two: A piece of chicken or turkey with a vegetable and wheat noodles
Dinner: A protein, vegetable and either rice of noodles. If you dont like rice or noodles eat more vegetables
Snack Three: Tossed salad with grilled chicken or shrimp
The main point was every time I eat something make sure I have protein.
I hope this helps.
