Answer: for this the easiest thing to say is overweight cousin or something like that. They have high cholesterol or something.
My cousin has been overweight and eating fast food a lot. They went to their doctor and they said their cholesterol was high for their age and they really needed to change their lifestyle so they can get healthy before it gets any worse. I told my cousin that although it’ll be hard it’s best to do it now before it gets harder. They have dreams of becoming a ( insert occupation) and if they want to achieve that they need to be alive and healthy.
