I think the interesting thing here, as the article mentions, is that correlation doesn't equal causation. There is definitely an advantage to exercise, and the brisker the walk the better, as it's good for cardiovascular fitness, joint health etc as well as burning calories. And people who are generally fitter are less likely to develop T2DM. But also people who are generally fitter/healthier are are less likely to have T2DM, and are probably also better able to move more and faster.

A potentially interesting follow-up might be to examine the correlation between number of daily steps, and pace, in patients with known Type 2 Diabetes and the reversal of the condition.

Supersize Me 2: Holy Chicken! covers this and is definitely worth a watch. He sets up a fried chicken restaurant and establishes all the minimum criteria to promote your food as free range/organic/healthy etc when it really isn't.

I went in with high expectations from having seen the trailer and was disappointed. It was beautifully shot, incredible sets, amazing cinematography, fantastic score, visually the whole thing was a joy to watch.

Sadly it was let down by the characters, who all ended up being fairly two dimensional (with some being so one dimensional it bordered on satire). The story was fairly dull, ended up being your 'strong but damaged man learns to care again whilst looking after a small person', with doses of 'US bad' and 'what if AI had feelings too?' (which ended up being rather clumsy).

It all ended up being too long, and suffering from some pacing issues which allowed you to think about all the plot holes and inconsistencies. It's a shame, we definitely need more well done sci-fi to stimulate the genre but sadly this wasn't the film for me.
