Rider - Even tho 100g of carbs per day is only "lowish carb," I think your plan to cut down from 200g carbs/day to 100g per day is a good one...especially as you mentioned that 1) you are a long-term diabetic and using glipizide which can easily cause hypoglycemia and 2) you don't need to lose weight.

On half as many carbs, you will need a lot less medication than you are currently taking. It would be really good if you could get a KNOWLEDGEABLE doctor to assist you with determining the proper dosage of your metformin and glipizide to go along with your reduced carbs. But, if your doctor won't assist you and you have to go it alone, then make all changes SLOWLY and monitor the results carefully.

You don't want to go into hypoglycemia. But, if you find that you have a tendency to go that way, the problem is not the lower-carb diet, the problem is too much medication!

Right now, you're driving a car (your body) down the highway with hurricane force winds (a high carbohydrate diet) attempting to push you off the highway in one direction (hyperglycemia). The hyperglycemia side of the road is strewn with rocks and ruts and thorn bushes that get worse and worse the further off the road you get. But, even the shoulder of the road (BG greater than 125) on that side is rough enough that every time you slip off the road on that side, your car takes a little bit of a beating. Maybe not enough to notice it but the tires are wearing out faster than they should, the paint is getting scratched up, etc.

But, instead of teaching you that YOU can actually control the winds by choosing a low carbohydrate diet, the standard medical treatment is to give you strong medications that basically keep the steering wheel of your car constantly turned INTO the wind.

But, of course, if you steer too hard into the wind, your car has a tendency to go off the road in the other direction (hypoglycemia). And, the hypoglycemia side of the road is a steep cliff drop-off that can kill you instantly!

So, knowing that your meds CAN force you off of the road and down that cliff, the doctors tell you "if you start to go off the cliff of hypoglycemia, eat some SUGAR so the carbohydrate winds will be even stronger and therefore can push you back in the other direction away from the cliff!!!

So most diabetics spend their lives constantly veering from one side of the road to the other. And to decrease the risk that their patients will drive off the cliff, many doctors (in fact MOST) tell them to deliberately try to drive along the hyperglycemic shoulder of the road (keep their A1C at around 6.5) even though the doctors know or should know that driving along that shoulder of the road is doing daily damage to their patients' bodies. After all, beat-up tires and a rusty paint job IS better than smashing off the hypoglycemia cliff.

But, wouldn't it be so much better to teach patients how to STOP the glucose winds from blowing? Then diabetics could drive straight down the smooth paved center of the highway like everybody else does! The risks of both hypoglycemia AND hyperglycemia would go away! But then, patients wouldn't need nearly as much medication and drug companies couldn't make nearly as much money off of their misery.

When you cut carbs, the winds WILL drop. You'll need to compensate for the reduced winds by reducing the amount of meds you take.

That's why, for diabetics on insulin or meds like glipizide, it is better/safer to SLOWLY reduce carb levels so they have time to figure out how much to reduce the meds to compensate for each change.

I think, what you're going to find is that it is a WHOLE lot easier to steer your car down the middle of the smooth highway when the winds you're dealing with drop from hurricane force down to merely a stiff breeze. I suspect you'll like the change so much that you will soon decide to drop your carbs even further.

Good luck. Go slow! And keep us posted! Oh, and to keep from losing weight, if you cut 100 g carbs from your daily diet, then ADD in about 10 to 20 g extra protein and 40 to 50 g extra FAT daily to keep your calorie intake about the same as it is now.
