My friend has been starving himself and vomiting up his food consistently for the past 2 years i’d say, he’s about 65kg whilst being around 6’1, i try to tell him that it’s bad for your health and that sooner or later he’ll just put the weight back on again anyway, but he hasn’t, he’s stayed being relatively skinny and there has been no changes in his behaviour or personality in fact i’d say he’s much happier than he’s ever been.

1. By starving yourself you can develop nutrient deficiencies. Eating is not just for getting calories but also vitamins, minerals, etc. and too little food might mean not enough of those nutrients. Depending on which nutrients are lacking basically every part of the body can suffer from this.
2. Starving yourself puts the body into survival mode. It literally thinks it might die due to not enough food. This leads to all kinds of unhealthy responses from the body to reduce the energy that it has to spend: muscles might be broken down to harvest energy and also reduce future energy need, the immune system is powered down, skin and hair suffer as they are not properly maintained by the body, fatigue sets in, mental capacity suffers, for women the period might stop.
