Why do anorexics drink diet soda?

It is a myth that anorexics drink diet soda because they believe it will help them lose weight. While some anorexics may drink diet soda, there is no evidence to suggest that this is a widespread practice or that it is linked to weight loss. It is more likely that they drink diet soda for its caffeine content, taste, or to help their stomach feel full. Additionally, because people with anorexia avoid food and weight gain at all costs, they typically are very hungry; the artificial sweetener in the diet soda gives a sweet taste sensation.
