I'm sorry but I have to say something here you can not detain someone under the mental health act because she did not have mental capacity. Firstly mentally capacity is specific " she knew that if she continued the way she was behaving she was putting herself at risk therefor she had capacity to make an unwise decision. Under the updated mental health act people are allowed to make unwise decisions. We can not go around sectioning people because they are doing things that we don't like. That happened years ago, remember women being sent to asylums because they got pregnant outside wedlock. Yes I use old fashion words because it's old fashioned. What the woman needed was intervention years ago. She also had the capacity to get someone else apart from her family to cone in and cook her a meal, that she put powder on thinking it would cut the calories, this was a misunderstanding because she thought she could have food as long as she used the powder. That is also a person who had capacity. Take a look at the program embarrassing bodies how does a person get a hernia that is so big that they can not walk or go to work 9 times out of 10 the Gp has done nothing about the condition telling them to live with it. It's all down to money and it will get worse. People need help, encouragement, and the right advice they don't need to be ridiculed so they don't go back for help, they need kindness. We don't need to be told we are fat when we know we are. Education is the key, we have a generation of kids who don't know how to cook, lots don't even know where most foods come from, why because they are not taught in schools or at home. There are some who are mad and there are some who are bad the rest just need care
