  One point to add:   Vigorous exercise can improve your sugars for up to
24 hours.    You pay a price at first (liver dump),   then reap benefits for
hours afterwards.

 The exercise liver dump is caused by the release of stress hormones,  not
really related to the Morning Effect/Dawn Effect,  etc..    The body sees
the exercise as stress and acts accordingly.

Eating before swimming I suppose is the same as any other exercise
except that the buoyancy affects the digestive system - a wild guess.

However depending on what you eat, you can guesstimate the time of the
peak BG after eating and start exercising around that time in order to
burn it as it hits your system.  For me, it tends to be porridge which
is a little slower than most carbs and should be 60-90 mins from first
bite.  I tend to be exercising before that point so there is a slight
danger of indigestion but I have only had it once.  Having said that so
long as I am being "good" and sticking to my routine I rarely have
indigestion which I did frequently before taking control.

Now that I have had 6 months of falling off the wagon, I am getting back
to routine again.  This means gym 3 mornings a week before work and
losing the extra kilos I have put on.  At dx I was 102kg falling to 77kg
after about 5 months.  Now I'm back to 84 so I desperately need to shed
some weight.  I never did reach my target of 76.  Want to race to lose a
stone ? ;)

I'll find out how much damage the last 6 months has done to my a1c and
other tests by the 22nd.

When you exercise, you burn the available energy in your blood system
first. Takes about 15/20 mins dependant upon exercise rate etc. After
this, you then begin to metabolise whatever is in your gut. Most
diabetics will not have a great deal so as your BG starts to lower and
when it gets to a trigger point, then nutrient is obtained from the
gut. If there is not much there then you start to burn the available
reserves stroed as fat about muscles. If you have little fat reserve
or the rate of energy requirement is too great then your liver will
dump to take up the slack until the fat is metabolised.

If you have weight to loose then fine, if not then when the liver
dumps you will end up weakening quite quickly. The tell tale sign for
me is when after a bout of heavy exercise I feel hungry. That means I
have nothing in my gut to metabolise and what fat I have [not much]
will take too long to kick in so I become damn useless.....tired and
feeling awful. if I get into this state I just sit down and nod off
for a few minutes and I can recover after about 15 mins [when the fat
burn kicks in].

The problem with a liver dump after exercise is that it does so only
once and then takes some time to recover. Whilst recovering, it bleeds
nourishment from the gut/fats and the net result is that after your
standard meal, you will feel hungry again sooner than you might
otherwise have done. This will tend to lead you into eating more than
you would want to and probably have an urge for something naughty.

I am very fit and from my experience I'd advise you to be wary of
feeling 'hunger pains' or a 'hollowness' in your gut during strenuous
exercise. If you do get this then you might like to ease off. When it
happens to me I pack it in altogether and review my pre exercise
meals.

If I know that i am going to be exercising or doing heavy and or
prolonged physical activity, I feed beforehand [the preceeding normal
time meal] based on my anticipated work load.

I think of it this way - I have a leaky fuel tank so I must only put
in what i intend to use. If I need more than planned for then I have
to stop and re fuel.

Fuel?? Well I decide on what to eat based on physical exercise
[anticipated] and how long I might have to go before the next meal.

I have discovered that I can last for a damn long time on a fried
breakfast.

Congrats on the weight loss but please be careful not to loose more
than will give you optimum benefit. Going too far will present you
with an impossible situation......trust me. Been there.
