Eyes on the prize, I live with my bf and his parents too and its hard! Take heart, know you are heard and keep at it. This is not an easy process. I want to eat all of the food they eat as well. For now, NO CHEATING! You just got here and although one slice of pizza wont make or break you, we have to make it a habit to eat healthy first. Develop the self control first. It is no easy task, its a change. For example, dinner time with the family will be a challenge. This is your chance to seize the moment and take charge. Good luck. No one can do it but you!
