I am no doctor or whatever but I just wanted to voice my opinion on this but I do take higher level biology. It's easy to say eat less? but for some people that is not an option. Why? It's because they lack the PYY3-36 hormone. There are three hormones that trigger the appetite control center (which is in the hypothalamus, in the brain), warning that the stomach is full. The three hormones are leptin, insulin and PYY3-36. If there isn't sufficient amount of PYY3-36, the person won't be able to stop eating since the appetite control center isn't triggered saying he/she is full. Because of this he/she gain weight at a quicker rate. This is obviously not the person's fault as it is the body's inability to to secrete the PYY3-36 hormone.

You may be thinking of Prader-Willi Syndrome which causes numerous physical and mental issues due to a defect on chromosome 15, one of them being an insatiable appetite. It is also extremely rare, fewer than 15,000 cases a year in the US.
That is not what I am "thinking" about. IK what I said. This is pulled straight out of my textbook soo...
This is so interesting, I had no idea. But another factor could be the thyroid.
That is true, there are a lot of factors to weight gain such as thyroid, but the most common and undetectable one is the PYY3-36 hormone deficiency. Also, there isn't much awareness on PYY3-36 hormone deficiency, so most people don't know. I am also guessing that there are some supplements that can be taken to control it, but I am not sure.
