Isoglucosia

Isoglucosia, a rule for calculating the amounts of protein and fat equivalent to 1 gram of glucose in food during muscular work. If a person does not perform work, then 1 gram of glucose in his food, according to the rule of isodynamia, is equivalent to 0.79 grams of protein or 0.4 grams of fat (depending on their heat of combustion). Chauveau and Seegen, who first proposed the term I., concluded that during muscular work, proteins and fats are first converted into glucose and then burned in the muscles, and therefore two quantities of food are energetically equivalent to each other if they are converted in the body into equal amounts of glucose. Chauveau and Seegen proposed the following average figures: 1 gram of glucose corresponds to 1.28 grams of protein and 0.62 grams of fat. The rule of I. is now almost never applied.
