Actions stem from thoughts and feelings, so if you think "ew I'm so fat and I will never lose weight" you feel lazy and sad, so you act lazy and sad, you overeat, or lay around all day... same works the other way. try to think "I am doing so great, I love myself, and i want to love my body" You will feel energized and happy, so you will go to the gym, and eat healthy! Try to think of your motivation. When a craving strikes think about your motivation (pray if you are religious)!
GOOD LUCK FOR MONDAY WEIGH-IN LADIES AND GENTS! (god knows I need the luck!)
