In order to understand this, you must first understand a few things about basic
vertebrate biochemistry.

All vertebrate life forms on earth RUN ON GLUCOSE; glucose is the monosaccharide
(single sugar) that we have all evolved to utilize to generate the very energy of life at
the cellular level. All "carbohydrates" are MADE of the COMPONENTS of glucose - Carbon
and Water, or Carbon, Hydrogen, and Oxygen, in a 1:2:1 ratio. Glucose is the SIMPLEST
carbohydrate: six parts carbon, plus six parts water, as follows:

6 x C = C6; 6 x H2O = H12O6; for a total of C6H12O6 for each molecule of glucose.

IN ORDER TO FUNCTION, our cells need glucose - to move muscles, for organs to function, for the brain to think.

Glucose is gleaned from foods (mostly carbohydrates, but if you eat no carbs, your liver
can MAKE glucose from the fats, proteins and fluids you consume).

As it is extracted, in the small intestine, it is released into the bloodstream - which
carries it throughout the body to be delivered to each and every living cell.

With the help of insulin, which opens the walls of the cells, that glucose enters the
cytoplasm of the cells - where it is immediately broken down to two pyruvate molecules.
Pyruvate is a three-carbon molecule, and much smaller - it can enter the mitochondria
of each cell, where it is ÿburnedÿ - oxidized - to generate ATP, the energy form that our
muscles, organs, and brain use to perform tasks and move about.

SOÿ glucose is the FUEL that our bodies run on. Our bloodstreams are the "fuel lines".
Our liver and long muscles are the "gas tanks" where we STORE glucose temporarily - as
glycogen - for use whenever we havenÿt eaten for a while (like while sleeping every
night) or whenever thereÿs a high demand for fuel due to INCEASED ACTIVITY.

Which is where your query comes in - "exercise" takes many forms, but generally
speaking, when that term is used, people are talking about performing some sort of
physical activity that is greater than their normal activity level. ALL activity REQUIRES
fuel - glucose - and when weÿre more active than usual, we are ÿburningÿ more glucose
than usual - to achieve that greater level of activity.

BUTÿ when we eat, we STORE glucose as glycogen (as described above); and THAT glycogen is used WHENEVER we become active - to supplement the normal BG (Blood
Glucose) supply, in order to fulfil the greater demand and drain on the bloodÿs supply.

SOÿ MOST folks see an initial RISE in BG upon starting an activity; and that increased
level will persist for as long as youÿre active. UNTIL youÿve actually begun to deplete
your liver stores of glycogen. Your long muscles use the glycogen stored in them -
thereby ÿsavingÿ the glucose in your bloodstream.

SOÿ go for a thirty minute jog, and most folks will see a slight rise in BG at the start; it
will drop a bit after a while, but probably remain higher than it was at the start - until
the jog is over; then, it will take a few minutes (five to ten) to return to the starting
level.

BUTÿ you will have "burned off" some of that liver glycogen - and if you are active long
enough, and intensely enough, you can reduce it a lot. And that will result in your post-
exercise BG being a bit lower than your pre-exercise BG level.

Think of your bloodstream as just the ÿfuel lineÿ, and your liver as the "gas tank"; even if
your fuel line is still full - your gas tank will have diminished from the exercise.

ANDÿ itÿs important to understand that in Type 2 Insulin-Resistant DM (Diabetes
Mellitus), there are TWO issues at play; not only do the bodyÿs cells not respond
efficiently to insulin, allowing BG to rise too high - the liver is "overactive", releasing
glucose into the bloodstream MORE THAN IT SHOULD. This can make exercising frustrating - because it may seem like your BG isnÿt lowering enough, and the exercise
doesnÿt get it down as much as it should.

BUTÿ and MORE IMPORTANTLYÿ regular exercise IMPROVES cellular sensitivity to insulin; and that is much more important than "burning off" BG. When the cells become
more sensitive to insulin, they donÿt need as much - and it becomes easier to control
BG.

ANDÿ when your active regularly, your muscles can uptake glucose withOUT insulin -
which again, lowers the amount of insulin needed overall; to the extent SOME of your
cells are getting insulin without insulin, the ones that arenÿt involved in the ÿworkoutÿ
have more available to them.

Each of us is a unique biochemical beast, and we each must learn our BG response
extent and rates with respect to different activities (intensity and duration), as well as
different foods. By tracking our BG levels before, during and after exercise sessions, we
can learn how well - or poorly - the different exercises we engage in control our BG
levels.
