Bob Cavanaugh's case is not relevant, as he has relatively recently made these changes, and therefore isn't at equilibirium. Same goes for your third guy, the BMI is from 2004/2009, while his caloric intake is from 2019 and was after a 5 year taper (and was therefore higher in 2009). Your first example. Pomerlau, weighed only 121 pounds - that's a BMI of 18 - and lost 5kg/year, which means that if he did eat 1200 calories, he almost certainly wasn't at equilibrium yet, either - it would take a few more years. None of those examples really are outliers.
