I had actually stopped working out for most of this year thus far because I have felt so lousy. I just started up again about a month ago with bodyweight exercises.
Today I failed waaaay to early. I didn't even complete the full cycle. I forced myself to finish push ups (had to cheat by using my knees at the end) and then couldn't complete my hindu squats....I only did 3 of the 5 sets. My heart was pounding, I was out of breath, and just has to sit for about 10 minutes. I decided to call it a day and hit the shower, and my muscles were all quivering. The program I'm doing is progressive so I shouldn't have been doing too much too soon.
Could all this be a result of my blood sugar issue?
It is possible that it is part of the problem. I know that when I was being diagnosed, exercise is discouraged UNTIL blood glucose levels are brought under control through diet and/or medication. This has to do with the potential of exercise induced catabolism can make the problem worse (and you cant just take carbs to combat it.)
However it may just have been that because of your situation you were motivated 110% and trained too hard considering your time off. Maybe try again but take it easier. Remember this is a marathon not a sprint.
Should I maybe consume something along the lines of oats 1/2 hour or so pre-workout to fuel the workout?
Remember, your current goal should be to get your problem under control. You should be on a calorie and carb reduced diet. Just try to have one of your planned meals somewhat close to your workout.
Should I still look to spike my insulin with a post workout shake?
No. In fact I don't recommend that any one do this. 'Spiking' insulin as defined in the BB community is not the greatest idea IMO but especially so for those with blood glucose issues.
And a final question about my apparent insulin resistance in general....it seems everything I look up says "rapid weight loss", but I did the opposite...a rapid weight gain. As I have said, I have put on 30lbs of fat in just over a year. Why would I gain fat? Especially since I don't eat sugar and eat mainly whole wheat anyway.
Ok firstly, you gained weight (fat) because of the QUANTITY of food you ate. Even 'healthy' food will put on weight if you eat enough of it. This is why most people who are serious about managing their weight, plan and measure what they eat. Yes this is a pain, especially at first, but IMO there is no better way.
As for your reading about insulin resistance causing rapid weight loss, it depends on the progression of the condition. Think of it this way, everyone's insulin function has a limit to how much food it can metabolize. Once you reach that limit it goes into overdrive and then starts to burn out. As it decreases, it can no longer maintain that body weight.
So what probably happened is that your insulin function was ok at maintaining your 215ish lbs. Then as you ate more and hit 245 and it reached its limit. If you don't make adjustments eventually your function will drop further and you would begin to lose weight. Your blood glucose levels will skyrocket and you would start to see the symptoms of excessive thirst/urination, blurry vision, etc. If you were to get on a diet and exercise plan that got you to say, 180 lbs, you might find that all symptoms disappear.
Hmmm....I think I need to talk to my Dr...... according to wikipedia on Metroprolol "This medicine may cause changes in your blood sugar levels. Also, this medicine may cover up signs of low blood sugar, such as a rapid pulse rate. Check with your doctor if you have these problems or if you notice a change in the results of your blood or urine sugar tests"
This medication may well be making your situation worse. However I would be hesitant to place all the blame on it and expect that if it were discontinued that you could continue with your existing diet.
