Musiclover... weightloss can vary from day to day....I have always been told to weigh yourself once a week at about the same time of day.... having eaten and drunk about the same too....
Idealy for me, I weigh in the morning after my first cup of tea!!!! lol (thats the time of the class I go to!!!!!) I have weighed myself a few days before.. and have seemed to of gained.... but generally I have lost!
I am like you, look at food and gain weight ......lol but if I eat the good foods I am fine :)
