Sister-in-law said, Sister-in-law, how to reply if you eat more?

My sister-in-law said that her sister-in-law should eat more, so she replied, well, I'll listen to you and eat more. Thank you for your concern. You should eat more and take care of yourself. According to relevant public relations materials: Sister-in-law refers to her husband's sister. Sister-in-law said that her sister-in-law ate more because of her family's concern. As a young aunt, she can answer politely and appropriately, and what the family says is not harsh, and she can reply in any way.
