Barbara Halloran Gibbons (1934 - March 26, 2014) was an American cookbook author and columnist.
Known as "the Slim Gourmet," her syndicated column of the same name was widely distributed in the 1970s, and popularized her ideas on diet cooking.
A number of her columns were humorous developments of her theory that "ingredients have no calories.
The ideas from Gibbons's humorous columns were collected in her 1982 book Calories Don't Count If You Eat Standing Up.
Since then, Gibbons's ideas developing her humorous theory that "ingredients have no calories" have been widely reproduced and distributed online, in private emails, and in the 1995 book Chicken Soup for the Soul Cookbook.
