I remember watching some rubbish diet programme years ago that said sit in front of a mirror while you eat...I can't think of anything worse than having a huge mirror directly in front of me as I sit on the couch
My mum, on her ever ongoing quest to lose weight promptly followed the advice, and bought 2 giant mirrors from ikea, one opposite the dining table, one opposite the sofa so she'd see herself snacking/binge eating at night and hopefully stop doing it. Only years later did I realise what the mirrors being positioned there meant
