energy transfer ?

If we use the theory that protein either from diary, meat and vegetable food items is transfered into useable glucose energy by the body at a slower rate then from the carbohydrate so will in the diebetic give more stable and controlable blood glucose levels, than that of camplex carbohydrates...

How can it cope with with fluxtulating energy needs, as different activities require different amount of energy to either enable it to happen, to be able to maintain the activity and then to leave enough fuel left after the acctivity has happened..

When I concider how I handle some activities, I use several factors, such as the lengh of, intensity of, type of activity, along side BG reading, insulin amounts (correction +/- ) enviroment etc to decide how much or what type of carb to take on board to achieve good stable control...

So looking at cutting carbs to a minium and using Protien/non carb source to fullfill energy needs, I can see a point that I would be using energy faster than the transfer rate... or could have enough energy to meet the need for a sort bust, but there is not enough energy being transfered at the correct amount to maintain levels during or after the activity has happened?

So how does it all work?
 
I think this is a question that Fergus could answer,if you remember one of his threads before about cycling and the Klebs cycle .
 
ive just started a biology course as part of my degree jo,
i may be able to answer in a few mnths but for now im stumped lol :D
 
I've understand the concept.... In whats going on, and that in part that the body needs to ability to adjust insulin requiments as necessary i.e stop or reduce production of insulin to maintain glucose levels in the blood...

But if I take the factor of Insulin, and that I'm a T1 diabectic so have none... So I have to inject this myself.... So this puts me into the the situation that If I've missed calculated then I'll faff the system as any insulin will continual to work whether it's needed or not...

Add another factor to this, is the small quanity of insulin I require to counteract cabrs/glucose or the liver putting into my system is very small indeed... means that even though I can accurately calculate my insulin dose, I'm then put into to a possition of can the equipment that I'm using deliver such a small dose of insulin accurately enough...

In my case the syringe or insulin pen can't as not only are you limited by increaments of 0.5 units (if you can get hold of the right pen/syringe) the tolernce level of accuratcy still has a impact, with out the concideration of trying to measure a dose to match mimium amounts of carbs... I wouldn't stand a chance of complying with Besrtien suggestion of 6g of carbs for breakfast... Even increasng carbs to match the lowest insulin dose I've available is a bit of hit and miss as the manufacturuing tolernace level then comes into play... Either giveing to much or to little insulin add that to the difference of site asorbtion I could ever inject into my legs as this increased the asorbtion of my insulin and generate a hypo.....

I've now use a insulin pump that yes in many ways give me more accuracy than I ever had, but there are times that having a increment of 0.1 units of insulin, will mean that to over come certain situations I'm back to utilizing carbs and type of carb to maintain good control, which rarely will I ever go above 8mmol/l and in general if my BG raises too much it's because of a pump problem i.e a bubble in the system...

It'm trying to see how low carbs or should I say the extreme carbs restriction of 30g, would benefit my control and maintain a safe control range that nither goes to high, or increases the dangers of increased amounts/serverity of hypos suffered...
 
I wish I could transfer some more energy to heat!!
 
Hi Jopar
You are constrained by the accuracy of the darb calculation too. the tables are not very accurate and the carb count on ready-made food is quite "iffy". Not to mention that no 2 apples, or potatoes are the same.
 
There's a lot going on behind the scenes. Your bloodstream only contains about 5g glucose at any one time (100 mg/dl x 5L) and this should be maintained by a constant shuffling of glucose in and out of store by the pancreas and liver working together and using insulin and glucagon. They only have to be out of sync by 5g and your BG has doubled.

Hope that gives you some perspective.

Exactly how the control circuitry is broken in different people can be key to understanding your own specific responses, some Type 1s seem to have much more functional livers than others and don't run the frightening highs or lows that others do as a matter of routine. I suspect that though you usually lack the insulin resistance at muscle receptors which is common in Type 2 you may still suffer from IR at the pancreas, liver or brain receptors.
