well my family eats 24/7 sometimes too. My dad eats so much, mostly junk food and my mom sees nothing wrong with being overweight. I've been going to Curves for 3 days a week and not telling my dad, or my boyfriend.
My boyfriend would support my weight loss efforts, he is the one who suggested trying because he is concerned for my health, and he is on a diet too...but always cheats on that. Plus I don't want to tell him I am trying to lose weight...because I'm afraid I won't lose it and then I'll be more disappointed.
I have joined a team, the Wildcats

they are very supportive and I'm glad I found then because I can talk to them about this rather than with my family...
