Well doing ok now with the new regime using exante packs plus extra calories on the days I run. As the time I run gets a bit longer the calories I burn can be up to 460 which explains the non existent weight loss when my total intake was 600. I'm still heading for 1200 calories a day and mapping that on my fitness pal. This seems to be working great as since getting back from Thailand I have lost 7 lbs and a total since starting exante of 4 stone. Really pleased with myself although I still think my weight is too high my body fat percentage must have dropped a lot
