Yes, my parents know that I am trying to lose weight. My dad doesn't think i'm overweight and so thinks everything i am doing is pointless but he always says i look nice so it is a completely biased opinion. My mum is worried that i will yoyo and lose weight then keep putting on more, which is what i have done so far (well, as yet i haven't gone over my starting weight, but i have gone back up to in on more than one occasion). She is overweight and seriously unhappy about it so she doesnt want me to get into the same cycle as herself so tries to do anything she can to stop me from binging/seriously restricting. Sometimes it's hard because i might really be motivated to be healthy or might want something unhealthy and so i shout but she is only trying to help and i guess it is better for myself in the long run. they are the most caring people in the world
