First of all; to those that still doubt; the low/no carbs regimen works!  After only a little over 6 weeks, I'm down 15 pounds and my readings are phenomenal -- consistently 4.5 (81) to 6.2 (110) throughout the day.  I'm afraid to start exercising lest I disappear entirely shocked
I don't have an exercise routine set up yet (well, I do golf & go for occasional walks) but am planning to get a treadmill and set aside some daily workout time.  My question is when to do it?
As I understand it so far, exercise will use up a lot of glucose, which is a good thing, but if done at the wrong time my liver will start kicking out more (too much).  Is this roughly correct?
In my personal case, my readings were highest from after breakfast to after lunch (recently, I've been able to level this out) so it would seem that exercise is warranted in early morning.  However, since I wake up at 5AM and mornings are hectic, its not practical.  The best time for me would be before supper (8PM) but this is where I achieve my lowest/best readings.

Answer: whenever you can :-)

I'm a believer in getting what you can throughout the day - i.e. I park in far corners in parking lots, get off the bus 3 stops earlier (or later), never take the elevator or escalators in malls/buildings, own a 2400 sq ft, 3-storey house that clean myself (11 steps to each floor), and live within a click of everything I need and "walk to shop" every other day (milk bags & cans are heavy :-)

Exercise is great to do after a meal as it improves the whole metabolism/digestion of food and insulin thing and there's less potential for lows (especially for Type 1's). If you're into the really into the aggressive exercise, morning through to supper is the best time for most. The more casual exercise can be done at any time without as much impact to BGLs. Exercising within a few hours of bedtime is not recommended.

Keep in mind that exercise can affect BGLs for hours afterwards.

Another thing about exercise is that it's results can often be delayed in your glucose levels. Exercising just before a meal is not usually recommended but as Phishbowl says "whenever you can" is better than nothing. It's ok to use up the glycogen from your liver for exercise... you will make more. That is there so you can continue to keep going. Otherwise after a little hard running after antelopes or wood chopping for the fire you would just pass out. tongue

If you want to find the best time for you to exercise, do it at one time for a few days, charting your results, then switch to another time and compare. If you test your sugar several times a day you should see a pattern that is linked to the exercise. Sugar levels can also be affected by the fiber present in some foods, fats that are eaten with food and whether or not the day ends in 'y'. You just have to keep testing till you find what your pattern is.

Congratulations on the great progress!!!
