I did c25k last year and didn't get any great weight loss only 3-4ibs over the 9 weeks so this time I have also signed up for one of the well known diet regimes to see if the two together make a difference.
On the Horizon TV program it said any exercise is good for keeping blood fat levels lower -good for staving off strokes & heart disease. As an office worker I am really up against it in the weight loss stakes because its sitting down all day that's the killer = need to get up and about more, walk around to talk to people instead of emails. The presenter followed 3 x 20 secs high intensity exercise 3 times a week for a month to get his blood sugar levels down, I think I prefer 30 mins c25k.
The program is still on bbc iplayer at the moment, it is really interesting
