Gotta be careful about burning them. There are cases on record of morbidly obese corpses causing grease fires resulting in fairly significant damage to crematoriums. In her book Smoke Gets in Your Eyes, Caitlin Doughty talks about having to cremate morbidly obese people first thing in the morning, before the oven gets too hot, to avoid this. (She has a YouTube channel called Ask a Mortician, but I don't know if she addresses it there.)
