Fatsecret was founded in 2006 in Melbourne, Australia by Lenny Moses and Rodney Moses. [1] As of 2019, Lenny serves as the company's CEO. [2] The company is known for its calorie counting and meal tracking app, and by April 2016, the company claimed to have 45 million users of its services. [3] [4] In August 2018, a premium version of its app ...
[13] [1] Lose It! also tracks data such as exercise/activity level and food consumption [3] [14] [15] and allows users to track calories consumed by scanning barcodes for food products then retrieving calorie information for products. [2] [16] The app can also estimate the amount of calories in a food products. [10] [17] [11]
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.
[1] [2] The large calorie, food calorie, dietary calorie, kilocalorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin). [1] [3] The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of ...

[2] According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child. [ 3 ] This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [ 4 ] with the exception of ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
The physical activity level (PAL) is a way to express a person's daily physical activity as a number and is used to estimate their total energy expenditure. [1] In combination with the basal metabolic rate , it can be used to compute the amount of food energy a person needs to consume to maintain a particular lifestyle.
