My husband, who is recovering from acute pancreatitis, has been told in no uncertain terms that his long-term recovery depends on minimizing fat consumption. (He also can’t drink alcohol, but that’s a moot point since he’s already sober.)
Obviously this poses a problem vis-à-vis travel in France, since many if not most spécialités régionales are drenched in the stuff. Whether it’s raclette in Savoie or cassoulet in Occitanie or pretty much everything in Lyon, most regional cuisines consist of fatty meat and/or dairy. The only exception that comes to mind is Nice and the rest of Provence; but is there anywhere else in France where a person who has to avoid fat could travel without feeling like he’s missing out on local cuisine?
