Most likely, they'll say hmmm, that's strange and you probably should try to avoid eating so much peanut butter in one sitting. Maybe they'll give you an invasive test that's probably not conclusive or inexepensive.

Doctors know next to nothing about gut biome stuff.
"I don't get full eating an entire jar of peanut butter" is going to result in the doctor telling me to not eat a jar of peanut butter.
Heck plenty of people don't get full eating entire tubs of ice cream. The answer is to avoid downing tubs of ice cream.
FWIW Salmon drenched in butter and lemon does the trick, but that kind of feels like cheating.
Maybe fish sticks would fill me up? Heck if I know.
Peanut butter is another one, plenty of people can eat crap tons of peanut butter and not get full. Other people get full from peanut butter easily.
Same goes for nuts, and a ton of snacking foods. That is why they are called snacking foods
I once had a coworker who could honest to goodness get filled up from an ice cream cone. Calorically, that is correct, but the vast majority of people's bodies will completely ignore calorie math when consuming ice cream (see: Common jokes about a separate desert stomach).

"Hi doctor, yeah, I have a normal BMI and I am in above average health and I work out multiple times per week but some guy online says I should see you because I don't get full eating peanut butter."
You do realize that there are literally not specialists for this stuff? If medical science understood why some people never get full eating certain foods, we wouldn't have so much obesity.
On the flip side, food scientists understand that fat + sugar = never satiated. That is why donuts are even a thing. Realistically a donut and a sweetened coffee are "enough calories" but they aren't satiating at all.
And then there is the nastiness of the human body mostly ignoring liquid calories all together[1], outside of mechanical fullness of the stomach. That is why starbucks can get away with selling drinks that have almost an entire day's worth of calories in them.
[1] Protein shakes are a notable exception to this.
I have a technique that works well 80% of the time: just pull the spine upwards and hope none of the smaller bones break off — and that's a nice, mostly deboned fish!
Maybe 4 or 5 good spoonfuls.
I'm willing to bet that almost any healthy adult could down 4 spoons of peanut butter w/o issue, and that most people would end up being way over their calorie limit for the day as their body wouldn't go "yup that was lunch and half of dinner! All good now!"
