Ria, I have been hypoglycemic for about 25 yrs. Even tho I no longer have to be diligent about eliminating every drop of sugar , the key is to eat 6-8 snacks/mini- meals. Large, starchy meals sure taste good and are fun at the time, but make me feel horrible and my blood sugar will plummet shortly after. I feel much better and don't get the hypoglycemic shakes and weakness if I will just spread my food into more meals, and eat frequently. If you do not overeat, this will actually help you lose weight, as it keeps your metabolism up.
Snacks and mini-meals shoud contain as little sugar as possible -- high protein and complex carbs like whole grains, brown rice, are best. Peanut butter, cheese, etc are great too, but I gotta toss the peanut butter -- it's so good I eat too much! Fruits are fine for a snack, keeping in mind that their sugar will not last long and you'll need to follow w/ something a little more substantial shortly after.
Anyway, keeping your blood sugar on kind of an even keel is best -- no overloads and no going w/o a little something when you feel weak. If you're going to try to follow an established 'plan', just spread the allowed foods out, so you are eating something about every 2 hours or so.
I am struggling now w/ weight gain, and have been for 2 yrs, hmmmm.... since that tick bite. I now have hypothyroidism which I understand can be caused by Lyme. Just started thyroid meds couple of weeks ago and hope that helps.
