Hey there!
My mother had struggled with her weight her entire life. Ranging from being super skinny and healthy to being very overweight and disgusted with herself. I have witnessed her go on and off many diets and exercise routines, lose weight and gain it back. In her adult life she has never succeeded in losing weight and keeping it off. I know the same is true for hundreds of thousands of people in the world.
Last year I managed to lose 50lbs through hard work, eating right and sticking to a plan. She always made silly comments about how I am "crazy" or "to dedicated" but I chalked it up to being jealous. She started really getting on my case when I hit 130, telling me I was to skinny and needed to regain some weight. I attempted to explain to her that at 130 and 5'5 I was totally within a healthy weight range. My mom started asking me for tips to lose weight but whatever tips I would tell her she would completely dismiss because "I didn't know what I was talking about". For example her breakfast is a milk shake, made with full fat ice cream, some meal replacement and maybe fruit. I told her she should switch the ice cream out with Greek yogurt or some milk and ice because that would give her better nutrition. She told me no because the ice cream has the calcium she needs and that a calorie is a calorie no matter what. When I attempted to explain that sure calories are calories but it does make a difference if its a calorie from bad fat or good fat she laughed telling me I was insane?! What?! I'm not the one eating ice cream for breakfast lady, sheeesh.
However she is not the only person to do this. My old boss at work used to do the same thing, ask me for advice and then dismiss what I have to say. My fiances parents do it to him to saying that he "couldn't possibly know what he is talking about". It has happened several other times as well but I am sure you get the idea now so I will quit my rambling.
Does anyone else experience this?
