Being a nudist invites questions: Is it the same as swinging? Is it exhibitionist? Predatory? (No, no and no.) What if it’s cold outside?

“The philosophy is, nude when possible, clothed when practical,” Ms. McMullen said.

For all their enthusiasm about eating, cooking can pose some challenges. Ms. McMullen has learned to take a big step back when taking food out of the oven, to avoid being clipped by a hot rack. Her husband mostly refrains from frying, and wears an apron when he does. When grilling, he keeps a good distance from the flame.

Nancy Rehling, 70, a retired restaurant owner who lives at Lake Como, said she wears a T-shirt when she cooks, to combat splatter. “I have scars all over my tummy and the top of my boobs from cooking,” she said — incidents involving fried fish, boiled-over soups and melted cheese, which “really sticks and keeps burning.”

But several cooks pointed out that safety and hygiene concerns are inevitable in any cooking. Table manners are no different whether someone is clothed or not. And a nudist is equally capable of preparing bacon, or any other food, as a cook in a full-length outfit.

“It’s not about the bacon,” Ms. McMullen said. “It’s about the freedom.”
