Well I am chuffed again - 15st 8lbs this morning - another 2lbs a week average.
A lot of my weight loss can be attributed to my running (I am training for the London Marathon so am averaging about 25 - 30 miles a week) as well as my eating habits (eating less and healthier foods). BUT I should let you know that around a month ago, when I got down to 15st 12, I tried an experiment - I ate what I wanted but kept up my running. Now I am a bit of a gannet - I can eat stupid amounts of food - so in this period, on one day I ate a load of donuts, chocolates, bacon roll, KFC etc etc
I was able to maintain my weight though - and as soon as I started eating sensibly again, I have taken more weight off - so my tip is: If you want to eat what you want or keep the weight that you have lost off - start an exercise routine.
And for those people who say that they can't run, walking the same sort of distances will burn off a very similar amount of calories :)
