I am a bit confused by your grammar, but I am guessing it was just a typo and you are asking why some athletes use steroids illegally. (no worries!)
Some athletes take a form of steroids — known as anabolic-androgenic steroids or just anabolic steroids — to increase their muscle mass and strength. It depends on the steroid, but most athletes who do take them are trying to improve their performance. I cannot answer as to why they do it illegally, it depends on what is going on in there head, but the above is why they may. Hope this helps, have a nice day!
I'm not 100% on this however I do believe the answer to this is: High-fiber diets are associated with greater weight gain in adults, because fiber-rich foods are less filling than foods that contain sugars.
i believe it is bulimia because it includes force full vomiting bad long term of loss weight excessive exercise and binge eating hope this helps
