Have you ever, even for once, had the thought of vomitting all the food you've taken into your system because you knew the food you consumed was unhealthy and you were trying to maintain your body weight/shape? Have you ever gone out for excessive exercises right after you took your heavy meals or right after you've eaten all those fatty foods? If yes, are you aware that you're actually engaging yourself to Bulimia Nervosa? Bulimia Nervosa is a type of eating disorder in which one would take excessive amount of unhealthy food but vomit the food or do exercised to get rid of the food consumed. These type of people know they are eating fatty food but they just cannot help themselves that they eat them anyway while trying to remain slim. However, they are doing it wrong because the regular vomitting will cause various damages to their organs.
