Hi

Not posted for a month or so but Ive now lost almost 2 stones since cutting down on carbs and running almost every night. Im really pleased with my progress and over the last 3 weeks have been back in my gym using the weights. Over the last week though Ive noticed that my bs have been higher than normal and especially after exercise (I now lift weights for about 45 mins and then go for a run for about 30-45 mins) In the past my sugars haven't been affected by exercise until 4-5 hours after but since going on the weights everything seems to have changed? My diet is pretty much the same except thst I am eating slightly more protein rich foods to aid in the weight training. Anyone any ideas to what the problem might be?

Cheers

Rich
 
Hi,

This is my first post so hope I can make some sense!

Is it possible your sugars are above 14 before you start exercising?? If they are they can rise instead of dropping as the feels it has no glucose in the muscles so releases energy from the liver (sorry if you know this :? ).

Also, due tot he increase of protein in your diet, this will be lowering the GI of your meals and it could just be that due to this, the carbs aren't being absorbed as quickly and causing you to rise when you're at the gym??

Hope this might help a little bit!
 
The other variable is the difference in exercise types.
Sometimes exercise can cause levels to rise a) if you are high to start with (insuficient insulin) and b) if the exercise is anaerobic. Have you tested your level after weights and before the run?
 
Also sometimes it can differ at different times of day. In the morning my liver is on a bit of a hair trigger and though I don't normally get Dawn Phenomenon excess exertion can cause it to shoot out too much glucose. In the afternoon it's more likely to make me go low. Tinkering with the balance of carbs fat and protein and probably the Alpha Lipoic Acid has helped even this out.
 
Hi

Thanks for the replies. Ive tested my sugars before doing weights and they are normally around 5-6. After doing the weights they can have risen to around 8-10. Its really bugging me and Im feeling that I should stop doing the weights as I dont want my sugars going that high. Could it be anything to do with the reduced carb diet that I on?
 
Read Bernstein on this. He believes lifting weights is good.
I use resistance bands. they don't hurt my toes if i drop them 8)
 
Hi,

I do a lot of resistance training and also find my sugars will rise. I usually start exercising at around 4-6, take no extra carbs and my the end of a seesion I can be up to 8-9. I find that a very small bolus just before starting helps to combat this. Around 6 hours after exercise I see a rapid drop back down though so watch out for that...

I also suffer the same with exercise.
Last night playing football after work, Before 5.5 after 11.0. Annoying thing is that there seems to rhyme-nor-reason to when this will happen. Last week a 5 and 10 km run had no affect, but the week before a 5km run put me up into the high 10s.
 
It's definitely a phenomenon that many of us have experienced.
The key for me is in timing excercise relative to the previous insulin dose. For example, if I run or cycle at a bg of 5mmol/l a few hours after I last ate, bg will definitely rise. If I do the same exercise within an hour of my previous meal, my bg will remain stable, or perhaps drop slightly so I might eat a little more to compensate.
So, for me, it's dependent upon the presence of insulin in the blood stream. Even a properly set basal dose won't accommodate the bs rise resultant from the stress hormones associated with exercise. Last Saturday I had a quick 30 mile training ride mid afternoon, and mg bg was, I think 5.1 beforehand. I used a half unit of humalog to pre-empt the bg rise and had a bg of around 4.6 when I got back.
Hope that helps,

Hi Fergus

nice to hear from you again. Because I dont like training within 2 hours of eating I suppose that the solution to my problem is to have a very small dose of novorapid before my trainig session. Annoying thing is that reducing my carb intake as you advised a while ago has helped me greatly in loosing the weight that I wanted to and also bring my sugars down to an acceptable level but when my sugars go up and I dont understand why (especially when exercise is involved and I always thought exercise would bring sugar levels down) this is a horrible feeling and I seem to solve one problem and then am faced with a new problem straight away.
Anyway fergus thanks for your advice a few months ago- Im now down to under 13.5 stone which means Ive now lost almost 2 stone in total. The first half a stone was very slow when I was eating loads of carbs but since taking in alot of your advice the other 1.5 stone has almost dropped off! My wife says Im too skinny now hence going on the weights to bulk up a bit-never happy are they :lol:
