It's more or less of not wanting to waste clinical resources on noncompliant fatties. So it's better to let these fats eat themselves to death than to deal with them because once they're dead, the only costs society pays for is their funeral costs and unfortunately, counseling session costs for their closest surviving relatives who are affected by this. But hey "My body, my choice!" and "My body doesn't affect other people!". Funeral workers are being pressured to sacrifice two plots of land for one dead obeast.
