People tend to get carried away in their attempt to lose weight. Various tactics are employed for the purpose, some of which are potentially life-threatening. An example of such a tactic is self-induced vomiting. There are people who make themselves throw up immediately after eating.
The rationale behind this is rather simple. If they immediately throw up the food content, the calories would not affect their body. However, this is a misconception that needs to be eradicated.
