Harris Benedict Basal Energy Expenditure Calculator Explanation and Clinical Context This calculator provides an estimate of energy required at rest using the revised Harris Benedict equations published in nineteen eighty four. These equations incorporate sex age weight and height to generate a prediction of basal energy expenditure. The result serves as an initial guide for nutrition planning and clinical decision m
explanation and clinical context The planner estimates basal metabolic rate using the Mifflin St Jeor equation and multiplies by an activity factor to estimate total daily energy expenditure. The calorie target is adjusted according to the selected goal maintain lose or gain weight. Protein is set to a moderate target of 1.5 grams per kilogram body weight to support lean mass and satiety while minimizing excessive pr
Explanation and Clinical Context A macro diet ratio describes the proportion of daily calories that come from carbohydrate protein and fat. These three macronutrients support different physiologic functions. Carbohydrate serves as the primary energy source for most tissues and supports high intensity metabolic activity. Protein maintains lean body mass supports immune regulation and contributes to hormone production.
Explanation and Clinical Context Nitrogen balance represents the relationship between nitrogen intake primarily from dietary protein and nitrogen loss through urinary and non urinary pathways. This balance reflects the body protein turnover and helps clinicians evaluate catabolic stress nutritional adequacy and metabolic demands. Positive nitrogen balance indicates that nitrogen intake exceeds nitrogen loss which is
Total Energy Expenditure TDEE Explanation and Clinical Context Total Energy Expenditure represents the total amount of energy that the human body uses in a full day. It reflects basal metabolic processes physical activity and the thermic effect of food. Basal Metabolic Rate is the energy required to maintain essential physiological processes at rest and it forms the largest portion of TDEE. Physical activity modifies
