Using BMR and 'Daily Caloric Need' to Gain Or Lose Body Weight

[quinn rithi]

Of these 6 components, the first four in the list all contain calories.   Science-Based Ketox Review  Calories are basically the amount of energy stored within each of these nutrients. Calories are needed by the human body to fuel metabolism. Metabolism is the process responsible for turning food into the energy needed to support life. The two basic metabolic pathways responsible for the conversion of calories to energy are the anabolic pathways and the catabolic pathways. Catabolism refers to the set of metabolic pathways in which molecules are broken down into smaller units causing a small amount of energy to be released in the form of heat, while the remaining energy is used to drive the synthesis of an energy transport molecule called adenosine triphospate (ATP).

ATP is basically a molecular form of stored energy and allows the transfer of chemical energy from one metabolic process to another. The metabolic processes that use ATP as an energy source also convert it back into its precursors allowing it to be recycled continuously. The ATP, created during catabolism, is then available to fuel the processes within the other metabolic pathway - the anabolic pathway. Anabolism is the set of metabolic pathways responsible for the construction of new molecules from smaller units. Anabolism is responsible for bone mineralization, cell differentiation and growth, and muscle growth.

Regulating calorie intake can affect both gaining body weight and losing body weight. Generally consuming more calories than the amount used by the bodies' current metabolic needs results in body weight gain. Consuming fewer calories than the amount needed by the body to fuel its current metabolic needs results in weight loss. For someone interested in attempting to either gain or lose weight it is very useful to know how many calories are needed, on average, to fuel the bodies current metabolic needs. I will refer to this number as the 'daily caloric need'. To determine the 'daily caloric need' it is necessary to first ascertain what is called the BMR or 'basal metabolic rate'. The human body burns calories 24 hours a day, even during sleep. The basal metabolic rate, which can be estimated by using the very simple formula you see below, is the number of calories the resting body would burn if absolutely no activity were performed in a 24 hour period.
