I don't want to blame my husband for sabotaging me, but he can eat anything he wants and never gains a pound...since the day we met he's been 125 and that was over 20 years ago. I've been up and down 4 times.
Keep it up, my dad's the skinny one too and he's always trying to feed us too much! It takes a while for others to get used to the changes we are making. Never give up! I'm sure he'll support you in whatever you do!
