Tell your family. You’re not going to lose the weight alone, even if you ARE alone in losing the weight. If you’ve got a family at home, talk to them about it – initially, not incessantly. Let them know what you’re going to do, and that you want (and need) their support. If you don’t let them know, you’re running the risk of them inadvertently sabotaging your efforts. You want them to help you get to your goal(s). You want them to share in your happiness when you’ve made it past a certain mark. Who knows? Maybe some of your new habits will rub off on them and they’ll become healthier people, too?
