I've been in a diet where I basically eat sponges and drink water. I weight 60kg and I'm about 1,63cm so I wanted to lose weight quickly and this has been helping me. I only eat a large bowl of soup at night and whenever I'm hungry I eat a piece of sponge (the size of the piece in the image). Today I'm going to the doctor with my mom to get an x-ray of my ribs and lungs and whatnot because I have been with what feels like to be the flu for almost a month. Will the doctor be able to detect the sponge inside my stomach? Will the x-ray show that?
