I actually went and skimmed the study, this is a very good article I would say in terms of lack of sensationalizing. That is exactly the main takeaway; perhaps we can get food (fat specifically) to ‘pass through’ us without being absorbed by the body. A fascinating possibility, if perhaps wasteful.

I’m going to be mildly annoyed if the fat acceptance latches on to this as yet another study validating their belief that they can’t lose weight.

On the very first page of the study:

The predominant increase in fat and calorie-dense food consumption worldwide has contributed substantially to the ongoing pandemic of obesity and metabolic disorders

Essentially what they’ve discovered is that they can interrupt a process that occurs normally in everyone, whenever there are fats in your intestine. The headline alone gives the impression of possibly being related to “set-point” theory, in which thinner people’s brains are just tuned differently. So yeah, I wouldn’t be surprised at all to see this start popping up in the spaces despite not supporting the stance at all
