Fun fact: doctors will recommend you drink protein shakes if you're chronically underweight or similar

For example: my dad is stupid thin and doctors make him drink at least 3 a week. My Dr makes me have one any time my Adderall makes me go a day or more without eating, or makes me feel as though I'm not hungry (I'll actually throw up even if I haven't eaten in days sometimes, which is fun)

Just a related fun fact
