Dietitian vs Personal Trainer: which is more exposed to AI?
Dietitian carries 14 points more AI exposure than Personal Trainer.
Dietitian sits at 40% time-weighted AI exposure against 26% for Personal Trainer, a 14-point gap driven by the 30% of dietitian work time that current models can already substitute outright. Personal Trainer holds a larger human-critical core — 58% of the role's time sits in work like "support clients through setbacks" that models score poorly on. The two sit in different families — Healthcare and Personal Care & Service — so any move between them is a career change, not a lateral step.
