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.
Intravenous sugar solution, also known as dextrose solution, is a mixture of dextrose (glucose) and water. [1] It is used to treat low blood sugar or water loss without electrolyte loss. [ 2 ] Water loss without electrolyte loss may occur in fever , hyperthyroidism , high blood calcium , or diabetes insipidus . [ 2 ]
The FAO/WHO uses different PALs in their recommendations when recommending how to calculate TEE. See Table 5.3 of their working document. Energy Requirements of Adults, Report of a Joint FAO/WHO/UNU Expert Consultation. [5] These equations were published in 1989 in the dietary guidelines and formed the RDA's for a number of years.
Graph depicting blood sugar change during a day with three meals. The glycemic (glycaemic) index (GI; / ɡ l aɪ ˈ s iː m ɪ k / [1]) is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food.

A nutritional Calorie is equivalent to a thousand chemical or thermodynamic calories (abbreviated "cal" with a lower case "c") or one kilocalorie (kcal). Because food energy is commonly measured in Calories, the energy density of food is commonly called "caloric density". [ 7 ]
If you're looking for a lower-calorie alcoholic beverage option, Wilson recommends searching for low-calorie beer or wine (depending on the brand, regular beer and wine can fall into the 150 to ...
The glycemic load (GL) of food is a number that estimates how much the food will raise a person's blood glucose level after it is eaten. One unit of glycemic load approximates the effect of eating one gram of glucose. [1]
Based on the work of Atwater, it became common practice to calculate energy content of foods using 4 kcal/g for carbohydrates and proteins and 9 kcal/g for lipids. [2] The system was later improved by Annabel Merrill and Bernice Watt of the USDA, who derived a system whereby specific calorie conversion factors for different foods were proposed. [3]
