I joined a group of people in a "biggest loser weight loss challenge". it's just some nice added support i don't have on an everyday basis from my family. I'm not in a relationship and don't want to be until i am 100% confident in myself.
Think about it this way - push yourself harder each day, than you pushed the day before. Say you want some chocolate (i know i do!) drink a glass of water and then if a full glass or two doesn't take away that craving eat a small fruit.
Have you tried snacking on frozen fruit when you are looking for the sweets? I like fresh frozen blueberries, they are so small and with them being frozen i *feel* like i am eating more than i actually am!
Keep your head up and think positively!
