Acarbose / GI question (macro, cockdezl)

DaMan

New member
Just to make sure I got this right - because of acarbose's carb-digestion-prolonging activities (can't remember name of enzyme it inhibits), and thus reduced insulin spike, does that mean that it basically "turns" high-GI carbs into low-GI ones? Or, more accurately, generates a slin spike equal to ingestion of a low-insulin-response carb even if the carb ingested usually generates a high insulin response?

(so basically, does taking it with white bread yield the same effects as taking it with wheat bread)?

Thx...
 
Hugh - metformin doesn't affect carb absorbtion but rather slin sensitivity at the myocite level... Thx for your help though.

Let's keep this thing bumped sista.
 
I HIGHLY dislike acarbose.

What it basically does is DECREASE the rate of gastric emptying,
leading food getting digested slower, and the macro-nutrients
being released slower.
So your analogy DaMan is a good one. It will reduce the GI Index
of a particular meal. Hence why its used by diabetics.

Problem: IT GIVES YOU REALLY BAD GAS!!!!!!!

Plus, you feel bloated as hell. Stomach-wise that is.

However, if you enjoy letting go of a fart or two dyring a board
meeting then by all means give it a shot. :)

LOL, if you tell me that you do 350+g of protein and do NOT fart a lot then you're not a real juicer :)

I just started taking it with my pre-oral-grapefruit juice in the AM to avoid the slin spike (really the only reason I got it, for the unfortunate times I only have high GI carbs for breakfast), so far my stomach is ok... will see how it goes.

NOTHING is immune to Designer Protein :) ...

give up the designer.. there are better proteins and cheaper..

main street ingredients has 50lb sacks of whey isolate for 3-400$

you can get calcium caseinate 50lb for less than 200 from amco

I just switched to myoplex after isopure (good but nasty). I had a day where ALL I drank was myoplex (had surgery the day before), 7 shakes total for 350g, and not one single queef. Not one. I was just using Designer to make a point... I"m not sure what that point is, but it makes you fart :-D

Anyway yea ginger root good.

Ok, you stumped me. I have no idea what Aminiguanidine is.

I can assume is similiar to phenformin because its in the biguanide
class of diabetic drugs, but what exactly does it do?

It is believed that the cross-linking of the proteins that make up the human body play a role in the human aging process. Everyone is familiar with the effects of cross-linking reactions, because the process causes food to turn yellow and become tough and it is the result of oxygen coming into contact with glucose and protein.

Cross-linking is medically referred to as Glycosylation and it may be responsible for many of the problems of old age, including senile cataracts, thickening of the arteries, cardiac enlargement, skin aging, some cancers and damage to the immune system. Aminoguanidine is a potent anti-glycation inhibitor, it appears to help prevent and possibility also break some protein cross-linking. Click here to see a figure depicting proteins cross-linking.

Animal experiments have shown aminoguanidine to prevent age-related heart enlargement and increase the collagen of arterial walls of aged subjects by 24-30%. Long term studies conducted in Italy, indicate that aminoguanidine reduces the “bad” form of cholesterol (LDL) in humans and improves blood platelet condition.

Recent human and animal studies also indicate that aminoguanidine improves diabetic conditions and improves the survival rates and longevity of animals. It even improves renal (kidney) condition.

Most interestingly of all, aminoguanidine may have the potential to slow the aging process by protecting the proteins that make up the human body. Proteins such as the skin proteins (collagen and elastin), eye lens protein, nerve protein and kidney proteins. All the body's proteins deteriorate with advancing age and more so in diabetes (diabetics have 2-3 times the number of cross-linked proteins when compared to non-diabetics and this has lead credence to the fact that diabetes can be viewed as a form of accelerated aging).

Aminoguanidine may be able to protect us from (or slow down the progression of) age-related cataract conditions and skin toughening and yellowing.

Aminoguanidine is an exciting new weapon in the armory of anti-aging medicine.

Doses are one tablet (150mg each) once, twice or three times a day. Aminoguanidine has a half-life of approximately 4-hours, therefore it is preferable to spread the dosage over the day with such a dose-sized tablet.

Please note that we supply a hydrochloride (HCL) based tablet. This is more expensive than a bicarbonate based version, but the HCL is more soluble, less irritating and is the type used in the clinical trials.

Aminoguanidine has not been shown to date to cause side effects any worse than nausea and headache. But as human clinical trials are still relatively limited, dosages shouldn't be exceeded unless under the supervision of a physician.

Aminoguanidine can inhibit the uptake of vitamin B6, so a B6 supplement is recommended whilst using aminoguanidine.

Aminoguanidine may be synergistic with Acarbose and Metformin.
 
Article on Acarbose

Explains acarbose's actions..read it carefully. You can't expect this drug to block the effects of eating the shit everone dreams of.


Pharmacokinetic-pharmacodynamic relationships of Acarbose.

Acarbose represents a new pharmacological approach to achieving the metabolic benefits of a slower carbohydrate absorption in diabetes, by acting as a potent, competitive inhibitor of intestinal alpha-glucosidases. Acarbose molecules attach to the carbohydrate binding sites of alpha-glucosidases, with an affinity constant that is much higher than that of the normal substrate. Because of the reversible nature of the inhibitor-enzyme interaction, the conversion of oligosaccharides to monosaccharides is only delayed rather than completely blocked. Acarbose has the structural features of a tetrasaccharide and does not cross the enterocytes after ingestion. Thus, its pharmacokinetic properties are well suited to the pharmacological action directed exclusively towards the intestinal glucosidases. The most important clinical consequence of the delayed carbohydrate digestion caused by acarbose is the attenuation of postprandial increases in blood glucose levels. Other effects have also been described: a decreased beta-pancreatic response to meals, and influences on gut hormone secretion and plasma lipid levels. Gastrointestinal discomfort is frequently reported as an adverse effect of acarbose administration, but incidence usually decreases with time. The suitability of acarbose for improving glucose homeostasis as an adjunct to dietary control or to administration of sulphonylureas or insulin has been extensively studied in patients both with type 1 (insulin-dependent) and type 2 (non-insulin-dependent) diabetes mellitus. Acarbose can be used as first-line therapy in patients with type 2 diabetes which is poorly controlled by diet alone. Moreover, the lack of bodyweight gain or hypoglycaemic effects reported during acarbose treatment may be advantageous for obese or elderly patients. Finally, the reduction in fluctuations of glucose levels throughout the day may help to control type 1 diabetes in patients with 'brittle diabetes'. Long term prospective studies are still needed to confirm these indications and the usefulness of acarbose in conditions other than diabetes, notably reactive hypoglycaemia and dumping syndrome.
 
metformin does slow the rate of gastric absorbtion...i dunno if this is just a side effect or one of the mechanisms of action. it really screwed with my GI tract.
