Intermittent fasting for blood sugar?

My blood sugar is usually around 250, even though I eat high-fat-low-carb, walk everywhere, and do tai chi in the mornings. Medications havent helped - after years of trying different things, the only thing that worked was fasting.

I did a 24 hour fast, midnight to midnight, which brought my blood sugar down from 250 to 150 (yay!). I broke that fast with a very small meal (180 calories, 8g protein, 3g carbs) and my blood sugar jumped back up to 250 and stayed there all night! After another 12 hours, its down to 190.

I dont understand why this happens. I feel like my only option is to fast indefinitely for the rest of my life. Any insight? Advice?

Was that in combination with insulin, or was that the only medicine you were taking? I think it would be a spectacular thing to try down the road :D

Interesting. Now that I think about it, my blood sugar was slightly lower when I was younger and eating less fatty meat and a little bit of rice almost every day.

Could you possibly give me a breakdown of where your calories come from every day?

Thanks for backing me up, @Harry. :)

I agree, that won't kill someone right away by any means, but eventually they might have to get a foot amputated, or they might go blind in one eye, or they might start losing kidney function. It's just not sustainable in the long term unless better control is achieved.

250 is high, yes, but most folks don't discover it until it's chronically elevated at 500+ mg/dL. You can survive quite a while at BG of 250, certainly, you're doing damage, but it's not a crisis that you'll die tomorrow.

This makes sense. Surely seems infinitely better than starving to death through "indefinite fasting" or getting renal failure from constantly elevated BG.

Good summary. Yeah, Metformin is one of the good drugs. I am taking, and eating moderate carbs. I've lost a lot of fat and still losing. I do get real exercise.

Doesn't exercise make it shoot up like crazy for you? I mean like right after. Wouldn't the cortisol/epinephrine release make your BG spike?

I am on Metformin. I was off because I was going to be in a clinical trial of a new diabetes drug. But I left the study because glucose shot up. I've been back on Metformin for a couple months. Today my glucose was 170. Not bad when I had surgery a week ago - got pacemaker, 5 hour surgery because doc is perfectionist. Then took antibiotics for 5 days as a precaution. Haven't been able to get as much exercise as I like this week. So I think 170 is OK. As soon as I can get lots of exercise, I'll be fine.

It's all in the dose. My wife is a nurse and we talk about medication and dosage all the time, trust me, you pump enough insulin in someone, you'll get a drop. Unless you literally have no insulin receptors in any of the cells in your body.....but if that was truly the case, you'd be dead.

100% insulin resistance = no glucose can enter cells = death

You don't look dead to me.....

It's a matter of dose, you will respond to a high enough dose of insulin.

@TheGastronomer When I was in the hospital a couple months ago, they shoved insulin on me because my glucose was around 250. It didn't do squat because I am insulin resistant. I find your responses very offensive.

The Paleo community is here to support each other, sure, but we're not here to tell you it's going to be fine if you continue having blood glucose around 250 without taking medication as long as you think happy thoughts. Grow up. This $h!t is serious and your health could deteriorate significantly, leading to diabetic complications. Stop screwing around and believing in unicorns, there's no magic cure so go to a good endocrinologist and take care of that $h!t. And fasting/starving for the rest of your life is not a sustainable solution, get real. That's the best advice you'll get. Good luck.

Are you still off metformin? Just out of curiosity, why hasn't your endo prescribed insulin, that's a pretty high blood glucose.

You know you're lying. Insulin lowers blood glucose, unless you're skipping it or not taking enough to cover your meals.

It's not condescending, if you're a diabetic you should behave like an adult and take your damn medication.

Thanks for the criticism, dude. You clearly didnt read the question. Do you think I have a blood glucose meter because I dont know im diabetic?

Ive seen multiple doctors and tried at least ten different diets and eight medications since 2007. ive been on both insulin and metformin - I am insulin resistant, and metformin made me so sick that I couldnt do my basic job functions for weeks.

I am in the same boat. My diabetes was controlled for seven years with Metformin. Then several things, including antibiotics made my blood sugar shoot up to around 250. (I also was off Metformin for a couple weeks.) My response was to cut carbs below 50 grams/day and add lots of healthy fat. (My doc had no suggestions besides "Wait and see if it comes down.) Various people in forums told me that fat can make your cells insulin resistant. I now eat 50-70 grams of carbs/day and much less fat. My blood sugar today was 170. Not great, but coming down. (I had surgery last week and was given a short course of antibiotics.)

1) Medication. Work with your doctor. Metformin is very well tolerated. Other medications are options. You can't simply ignore medication as a treatment option.

2) Eat a normal level of carbohydrate (20-40% of calories). Very low carb induces physiological insulin resistance and elevated BG levels.

3) Lose weight. Excess weight decreases insulin sensitivity.

4) Exercise (real exercise) in addition to more general activity. Exercise increases insulin sensitivity.

I experimented with Sodium R-alpha Lipoic acid a while back and soon stopped using it because it drove my glucose down into the ground (mimics insulin.) Not sure what it would do for you, but it might be worth checking out with your doc.

You have full-blown diabetes. And judging from those numbers you should really do a better job of managing it. No one should be having blood glucose readings that high. Have you gone to a doctor and spoken about your blood glucose readings? Please consider going to a doctor if you have not already done so. I wouldn't be surprised if your doctor put you on insulin or at least metformin, those numbers are scary.

"I feel like my only option is to fast indefinitely for the rest of my life" - actually, they have a word for that, starvation. The outcome is death.
