A lot of great points on this thread already. I'd love to discuss some of these things sometime. I know there is a lot of extra baggage for diabetics when it comes to exercise, but I've learned a great deal that has helped me tremendously.
The point that was made mrmikelawson, about running off some calories and then putting them back. I totally get what you are saying! But trust me, exercise helps you in so many ways. It isn't just the calories you are burning on the treadmill. Your whole metabolism gets better. Over time, your insulin:carb ratio gets changed, your correction factor changes, insulin sensitivity, total insulin usage. Over time, your body become a much more efficient machine. If you exercise regularly, you will lose weight. Unless you are just standing on the treadmill eating pies, I promise you, you will not add more than you burn. But I understand your point, and I loved that gif!
Marianna11, yes absolutely. I agree with the opinion quoted. And it isn't just a lack of reliable information, there is so much bad information out there too.
There is a lot to learn about exercising with diabetes. I mentioned this on another thread, when exercising, you can "feed the basal", or you can "fuel the exercise" and "bolus the fuel". And what you do and how you do it depends on so many things. Your correction factor for high BG is different while exercising, so how you correct is different.
The type of exercise affects which way your BG will go. Before certain workouts, if I am at 90, I will take insulin immediately before running, because I know the workout will make me spike. It sounds crazy to most people, and certainly a CDE would freak if I told them I do that.
There are easy ways to test when running. Fumbling for strips is horrible. I made this to help with that problem, and I can test without stopping. And I also put a BG meter on a watchband.
There are so many things diabetics have to consider differently. Like for fat burning exercise, if your blood sugar is too high, you won't be able to metabolize fat. Nobody tells you that, because they always worry about hypos. But if you look at what is required for fat metabolism - the krebs cycle, and what it requires - a small background of carbohydrate metabolism, you can connect the dots and see that if your BG is too high, you are not able to metabolize carbs, and ultimately you won't burn fat. You will just use muscle glycogen. Not that using muscle glycogen is bad, but if you want to be metabolizing fat, and you are instead using muscle glycogen, you aren't accomplishing what you want. If you want to burn fat, you should try to stay in range to allow the background of carb metabolism to occur. ("The Krebs cycle is is the only metabolic pathway to burn fat in addition to carbohydrates and protein for energy production." - http://www.livestrong.com/article/366560-human-metabolism-the-krebs-cycle/).
Apologies for my scattered bunch of thoughts here. I agree with the quote referenced in the link:
When trying to find good reliable information, it took me forever. I'd love to hear thoughts on exercise, weight management, and handling the little extra baggage we have to attend to with diabetes.
