even though i am on week 3 run2 completed i have lost no weight. Prior to starting this program i did no regular exercise. My intake of food remains the same and i do try to eat healthy, lots of fruit,veg,fish etc but i have not lost any weight. I was told that running builds muscle which weighs heavier than fat, is this true? Should i just keep a record of my measurements rather than hopping on the scales? Has anyone else come across this i would be interested in knowing if i am not alone.
