I know I can't save everyone. But my dad is killing himself from eating too much. I educated him many times about weight loss because I started a healthy life style months ago, but he won't take it seriously. Right now he canceled a airplane flight because he is too sick. His reason is because he's too sick from eating too much. He told me right now he's going to change his way (80% sure its bullshit) but how do I guide him? I have the knowledge but I don't think he will put the effort in.
