Found the doco really interesting. Have watched some other docos by the same guy as part of uni studies actually. He does one about ageing which is fascinating too.
It's been know for a while that exercise (even light exercise) can make a big difference to insulin sensitivity, but I didn't know that the quick burst of exercise (3min week!), could have such a dramatic effect on it too.
While it's a really great finding, I think it's use could be a bit limited to people who are already fairly healthy as it's very intense. I can't see a lot of obese people with type 2 diabetes wanting to do such an intense exercise, no matter how short it is.
The incidental exercise findings were good too although not all that unsurprising. It doesn't really take much to burn extra energy. Just staying off your bum, taking the stairs, walking around as much as possible. Personally, I found a big difference when I stopped working. I went from working in a lab where I was walking around most of the day, and I had to travel up and down stairs to go from the office to the lab. I went from that to being stuck at a desk most of the day. I would go for a walk/jog/bike ride for about an 30-60min most days but I still put on weight and had to adjust my eating.
And in terms of the non-responders and super responders, I understand now how it can take me weeks of training to improve my fitness, however my other half can do nothing for weeks then go for a couple of bike rides, and be able to climb mountains and ride 200km without any problems. It's not fair!
