By definition, that wouldn’t be a deficit. You could have a “predicted” calorie deficit that ends up being off by some percentage. The models for energy expenditure typically just use pretty simple demographic info like BMI, sex, age, and activity level. If someone burned less calories than predicted, that basically means that they are less fit than the average person of their demographic cohort.
You could use more advanced models with more information, but they would still be predictions. Drugs also come into play: uppers like caffeine, nicotine, amphetamines, etc, increase the amount of activity in your body so you are literally warmer from burning more calories, everything else equal.
Unironically, yes. Lots of off the shelf diet pills are literally just caffeine pills (e.g., hydroxycut). Old school diet pills were literally amphetamines before governments made it so you couldnt get them off the shelf (e.g., obetrol), and technically you can still get it prescribed (desoxyn is methamphetamine).
The problem is, a normal dose of caffeine just makes you a little warmer, and burn a little bit of extra calories, but amphetamines and especially 2,4-Dinitrophenol (other banned weight loss drug) can literally cook you by making you burn so many extra calories.

So you’re saying all I have to do is drink a lot of coffee and take a lot of uppers
