The Wishnofsky Rule states that one pound of human fat tissue contains about 3,500 kilocalories (often simply called calories in the field of nutrition). Wishnofsky conducted a review of previous observations and experiments on weight loss and weight gain, and stated his conclusions in a paper he published in 1958. [4]
A single pound of fat yields approximately 3500 calories of energy (32 000 kJ energy per kilogram of fat), and weight loss is achieved by reducing energy intake, [105] or increasing energy expenditure, thus achieving a negative balance.
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
Based on the steps above, a 180-pound, 5’11” man who trains five times per week needs 2,650 calories daily to maintain his weight and would eat 2,275 calories per day to lose three-quarters of ...
Low-fat diets are intended to reduce the occurrence of conditions such as heart disease and obesity. For weight loss, they perform similarly to a low-carbohydrate diet, since macronutrient composition does not determine weight loss success. [1] Fat provides nine calories per gram while carbohydrates and protein each provide four calories per gram.
