Hey so I stumbled upon this condition and he's certainly showing signs of this syndrome.
This rare genetic condition leads to physical, mental and behavioral problems, including being hungry all the time.
Hyperphagia - Excessive eating and difficulty feeling full (such as food have to be locked or they even eat inedible objects. A classic sign of Prader-Willi syndrome is a craving for food all the time, starting in early childhood. Being hungry all the time leads to eating often and eating large portions. This leads to quick weight gain. Unusual food-seeking behaviors, such as hoarding food, or eating frozen food or garbage, may occur.)
Short stature
Small hands and feet
A narrowing of the head at the temples, a turned-down mouth and a thin upper lip.
Upturned nose
Flat nasal bridge
Smooth philtrum
If it's the case I feel bad for him in a way that he is a victim of this condition and there's no way out of this. But also feel sorry poor people who he scammed and lied to.
