Convincing A younger sibling to lose weight

Maybe you could suggest spending time together and use that time to get fitter together you could both go to the gym or go jogging then you both get the benefits.

There becomes a point in everyones life when they sit there on there own at the end of the bed , staring vacantly into space or in the mirror , asking themselves one question . "Am I happy " there can only be a yes or a no answer to that . If the Person is happy , then let them be . If they are not happy , you will be able to tell . Your sibling will be watching you get smaller in size and will realise that she wants what you've got soon enough . Sometimes losing weight is hard . Some people just need visual encouragment , and some people just need to participate in the other persons life . Sign her up to an activity club you both like , eg Badminton , or walking club . Something that is gentle but uses energy . Its amazing how much weight can be lost just doing a few simple things .

I think that maybe you should see if she doesn't want to take walks with you or do other activities such as playing sports. This way she is being active, and having fun as well. She will lose weight, feel better about herself and be proud of the weight she's lost. I know I need to lose a little bit of weight, I don't weigh too much but my BMI is high I am sure, and I do eat too much.

My advice: don't. It's up to her to decide whether she's happy when she's bigger or smaller, not you. Trying to convince other people to change the way they are is a recipe for disaster and bad feeling. Leave her to work out what she wants for herself.
