Is a calorie a calorie?
The aim of this review was to evaluate data regarding potential thermodynamic mechanisms for increased rates of weight loss in subjects consuming diets high in protein and/or low in carbohydrate. Studies that compared weight loss and energy expenditure in adults consuming diets high in protein and/or low in carbohydrate with those in adults consuming diets low in fat were reviewed. In addition,...
متن کاملAdipose tissue metabolism and calorie balance.
Adipose tissue can no longer be regarded simply as an inert storage site in which fat formed in the liver or derived directly from the diet is deposited, and from which during fasting fat is ‘mobilized’ and ‘burned’ in the liver for energy. The use of substrates labelled with radioactive isotopes has established that these fat ‘stores’ are, in fact, constantly being turned over, and that most o...

متن کامل"A calorie is a calorie" violates the second law of thermodynamics
The principle of "a calorie is a calorie," that weight change in hypocaloric diets is independent of macronutrient composition, is widely held in the popular and technical literature, and is frequently justified by appeal to the laws of thermodynamics. We review here some aspects of thermodynamics that bear on weight loss and the effect of macronutrient composition. The focus is the so-called m...
متن کاملIs a Calorie Really a Calorie? Metabolic Advantage of Low-Carbohydrate Diets
The first law of thermodynamics dictates that body mass remains constant when caloric intake equals caloric expenditure. It should be noted, however, that different diets lead to different biochemical pathways that are not equivalent when correctly compared through the laws of thermodynamics. It is inappropriate to assume that the only thing that counts in terms of food consumption and energy b...
