>Why can't my mum stick to losing weight?

Shes 56 years old and 100kg or so, she always falls the fuck off with diet and exercise after about a week or so.

Shes constantly coming up with excuses etc.

Our family has good genetics in terms of age (my mums parents are in their late 80s and still healthy) and not fat. So my mum thinks because her parents are like that that she is fine and that i worry too much.


What will it take for her to just stfu, stop making excuses and just lose the fucking weight?

She was literally 50kg or so up until her 40s, she she was thin for most of her life. Shes really let herself go now though.
