Default Does intensive diet and exercise help reduce blood sugar levels in type 2 diabetes?

A year on an intensive diet and exercise programme can help people with type 2 diabetes get their blood sugar levels back to normal, a new study in the United States has found. Indeed, one in nine people with diabetes saw their blood sugar levels go back to pre-diabetes levels after 12 months, the research [...]

Not sure how anyone could get a research grant to demonstrate such an obvious end point. Its like studying the effects of slapping yourself in the face, it eventual hurts.

Great illustration of the dismal success rate of calorie restriction. They say nothing about the composition of the diet but dollars-to-donuts it was low-fat, high carb and filled with PUFA for what little fat it did have. 1200 calories is also bordering on test subject abuse and completely unnecessary for BG control - if ony they could cut loose from their misguided orthodoxy about diet and nutrition. Furthermore, long-term compliance is very unlikely on such a cruel diet, making this impractical as a treatment methodology. Oh, what do you know, that would force the victims back to the meds - happy funders! Proving that diet is "OK" to a point, but YOU STILL NEED US.

One in nine is a terrible rate for a dietary intervention with what sounds like really good monitoring and compliance. Although it is unlikely a grant would ever be forthcoming, tons of anecdotal evidence and personal experience would predict more like EIGHT OUT OF NINE would get those results or better with a LC/HF diet - exercise OPTIONAL (good for other things but irrelevant to BG control in this context).

Furthermore, based on the methylglyoxal/oxidative stress theory of T2, this plan would do little for progression, since the subjects would still be 100% reliant on glucose for cellular energy, and relapse after a few years would be the expected outcome.

OK, ranted a little. Over.

Right. However, IMO exercise is not completely irrelevant. Physical activity would determine how many carbs one could tolerate per meal or day, even when low-carbing.

Fired up there, eh SMORGAN?
For me, excercise makes a big difference. Newly diagnosed, went on a one-hour run which saw BG drop from 176 (9.8) to 86 (4.8) during that time. BG's were considerably lower than expected the following day too.

No doubt, exercise can make a difference in certain people and at certain stages. When I visited the CDE after diagnosis, she told me that, "Exercise, not matter how diligent will work FOR A WHILE but later on will stop working."

Most of what she told me was nonsense but I think she just could have been right on that one. Anyway, that one is a long story and I'm not even sure I remember my own logic which led me to think that what she said was actually true.

Back to exercise and glucose. Barring very extreme exercise where muscles must have glucose and often get it from their "local" glycogen stores so completely removed from the whole blood-glucose loop, all other exercise can be fueled by EITHER glucose or other things (FFAs and ketones). The more firmly one is in ketosis via a ketogenic diet, the less muscles need, demand or use glucose - exercise or not - up to the possible endpoint of virtually none.

In this state, exercise has nothing to do with BG control. For all normal and endurance exercise, your muscles are not even using glucose, so no give-and-take at all with circulating glucose. Even in extreme exercise, your muscles will mostly use their own glycogen, i.e., glucose and/or protein you ate previsously like yesterday for example, again unrelated to circulating glucose.

If I exercise and show any decrease in BG, I know I've slipped and need to fix my diet. I'm stil very much "low-carb" and probably even have ketones in my urine, but I've slipped out of my ideal state of minimal glucose use.

That's what I was referring to.

The Effect of Walking on Postprandial Glycemic Excursion in Patients With Type 1 Diabetes and Healthy People

CONCLUSIONS Walking significantly impacts postprandial glucose excursions in healthy populations and in those with type 1 diabetes. AEP algorithms incorporating PA may enhance tight glycemic control end points.
