There are a number of pieces of work ongoing at the moment, looking at exercise and blood glucose. One such research piece is happening at Leicester where they were totally disinterested in weight gain/loss, purely blood glucose numbers.
The process of merely standing up for 5 minutes every hour had an impact on blood sugar results. That's standing up; not standing up and moving around or anything else. It appears that the trigger is utilising the large muscle groups required to get from a sitting, or lying position to vertical that does the trick. Any more than than is a bonus. I would add that to focus on exercise for weightloss never makes too much sense to me as so much effort can be required to utilise enough energy to make a difference, and then what happens if an injury occurs, or life gets in the way of that regular exercise regime.
If you enjoy your new exercise regime, I would certain not discourage you from doing it, but using it to gain or lose weight is a toughie, in my opinion.
