 One of the most common issues that people complain about when they take these drugs is that they lose their pleasure in food. In fact, Jens Jols Holst, who's one of the scientists who developed these drugs, said in an interview with Wired magazine that he thinks this is just going to be a really big problem because people lose their pleasure in food and you just can't live like that. However, that concern hasn't stopped these drugs from rising in popularity. With the internet and telehealth, access to medicine has never been easier, which has Hari worried that they'll be abused by people struggling with eating disorders.
