Yes. I have been diagnosed hypoglycemic and have worked with nutritionists to stabilize things. It took a long time but I have been totally free of blood sugar crashes for several years due to VERY careful diet planning.
It makes me so happy to report that because for a while I would crash almost every day and it scared and frustrated Hubby and was uncomfortable for me.
First of all, try to spread your proteins out throughout the day. Food have a glycemic index which means they absorb at different rates. Processed flour and sugar are the fastest while proteins and whole grains are the slowest.
Try to cut a lot of high-glycemic food out and replace them with low-glycemic foods. I try to be realistic though. I still allow myself a treat, you know? But I am SO careful about WHEN and HOW MUCH. If you're going to eat sugar, eat it after you have had a meal with protein in it and don't have very much. Half a cookie will still taste like a cookie, ya know? Fruits have a lot of natural sugar and I eat them only with meals.
Also, have a small snack in between meals. The snack definitely needs to be low-glycemic. Some triscuit with cheese or peanut butter. Coffee with lots of milk. Something like that.
Get yourself on a schedule of meals and snacks that maintains your healthy weight and stick to it. I generally eat (if I am not dieting):
Breakfast: Bowl of cheerios and milk
Mid-morning snack: latte (little or no sweetening) or celery and cream cheese or yogurt or pita chips and hummus...
lunch: something with a little protein, a little bread (whole grain preferred), as much veggies and fruits as I want. Snickers Mini for a treat sometimes.
Mid-afternoon snack: triscuit and cottage cheese maybe
Early dinner (timing is vital...not too late): normal, healthy dinner.
snack before bed: whole grain toast with peanut butter
When I am dieting, I often have a latte for the snacks and eat smaller portions at meals but the same categories of foods. I cut out as much sugar as I can but not so much that my body craves it and drives me nuts. And I personally don't use artificial sweeteners because I don't like the "chemical" aftertaste. I just never eat sugar by itself, EVER. If I do, I can count on my blood sugar spiking in about 10 minutes and then crashing after about 20. Bad idea.
If you do crash, and get all dizzy and grumpy and can't think straight, drink MILK, not juice. The milk has enough sugar in it to get you up again quickly and enough protein to stabilize you until you can have a meal. Try to eat a meal soon after a crash, especially if it is time for one on your schedule.
I would highly recommend seeing a nutritionist... it was so helpful to me.
If you want more info or want to chat, please PM me because I have been managing this for years. It is not that hard once you get into a rhythm and you feel SO much better without the blood sugar crashes!
