How to make myself look fatter? Is there any way? Help really urgent?

So I'm going to visit my mom I haven't seen her in 3 months I love her very much but she worries to much especially about my weight when I loose 4 pounds she starts to freak out and crying really worried about my health. Since the last time I saw her I lost 37 pounds so she is really going to freak out and have a meltdown. I love her a lot and I don't want to worry her. I'm a little bit underweight but I feel healthy and strong.
Is there a way to seem fatter in the eyes of my mom
