I am prone to bloating and i didn't eat the best yesterday. Although 2.1kgs seem a bit excessive. Oh well, on the positive side my skin is looking clearer and my jeans are still feeling looser so will definitely keep at it.Oh no!!! Is there any reason you can think of for that to happen?? Like bloating or something?? I'm disappointed for you. Don't let it get you down though ... Just jump back on the horse this morning and turn that number back down!!
