well, the title says a lot. i have read many things about what it is and how it affets you. however i remain totally clueless.  maybe i need one of those simple lessons that contain no big words.
 
how does it change when you gain ot lose weight?  is it measurable and if so using what test?
 
is it true that all people that are overweight are insulin resistamt?  is it true that people of normal body weight always have normal insulin resistence?   is it possible for insulin resistence to return to normal with weight loss?
 
 
you guys ROCK, thanks

Pebbles,
This is my own interpretation of insulin resistance... not really scientific. I believe that it's a left over anti-famine mechanism. When there is an abundance of grain based foods in the diet the body thinks it's 'autumn/harvest' time. This switches it over to the 'fat-store' mode. The fat cells increase and in turn tell the body to grab more food to make more fat because in a 'cave person' survival type of way the body needs to store while it can. Harvest is a short lived time usually followed by a period of less food so our bodies evolved to efficiently store what it needed whenever there was abundance.

Our bodies don't know that there is lots more grain based food in the grocery store. By eating these foods all of the time we fool our bodies into thinking it's always harvest time so rather than shuttling the blood sugar into the cells for immediate use we pack on the pounds. Increased fat sends higher signals to save more fat. Just my take on it.

I think it's hard to answer your questions with a definitive "yes" or "no".  Although there might be other tests, most doctors probably use the GTT (glucose tolerance test) to see how we metabolize carbohydrates.  That's probably the test that really diagnoses diabetes.  Other tests like measuring our blood sugar with our monitors fasting or after meals and the A1c which is the lab blood test that measures our 90-day average blood sugar will tell us how we deal with carbs on a daily basis.  I don't know if all overweight are insulin resistant but maybe most are.  This can change if they lose weight but they will most likely have to be careful with their diet.  Some people with normal body weight do have diabetes.  They may have type 1 and so produce no insulin or they may be type 2 and not produce enough or are insulin resistant.  All groups benefit from diets that are low in carbs.  I think it's tricky to say that it's possible for insulin resistance to return to normal after weight loss.  To me, this means that after losing weight, the person could eat a "normal" diet and still have normal blood sugar readings despite eating carbs.  I don't think this happens.  I think once a person becomes insulin resistant, his metabolism system will always be impaired and not be able to deal with too many carbs in the diet even if his weight comes down.  That person may be called "pre-diabetic".  Just how many carbs a person can deal with depends on the person though because each one is different.  (I know this sounds confusing but the bottom line is diabetes can be controlled very often with diet and exercise but if that no longer is effective, then you would have to start meds.)

diabetes controlled so far by low/no carb diet and exercise; no meds
