this is why you don't eat so much saturated foods like me i went to the doctor after i threw up. so don't eat to much saturated fat things with a lot of calories and other unhealthy junk food.
your stomach can not hold to much food so don't eat to much or you can get obesity
He is throwing up because he can't hold that much in his stomach and some of those fat cells is making him fatter and theirs a high risk of obesity.BTW he might go to the doctor
