EBAC is the estimated blood alcohol concentration (in g/L) A is the mass of alcohol consumed (g). T is the amount of time during which alcohol was present in the blood (usually time since consumption began), in hours. β is the rate at which alcohol is eliminated, averaging around 0.15 g/L/hr. [31]
Widmark originally used units of mass (g/kg) for EBAC, thus he calculated the apparent mass of distribution M d or mass of blood in kilograms. He fitted an equation M d = ρ m W {\displaystyle M_{d}=\rho _{m}W} of the body weight W in kg, finding an average rho-factor of 0.68 for men and 0.55 for women.
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.
With all this information and opinion, it might seem tricky to calculate how much alcohol is safe to drink. ... Regardless, as a general rule of thumb for alcohol intake, less is generally better. ...
You can calculate your maintenance calorie intake by working out your basal metabolic rate (BMR), then adding in extra calories based on your normal activity level. Practice mindful eating.
The National Institutes of Health has a body weight planner that you can use to calculate your target food intake based on your optimal weight, age, height and activity level.
The Estimated Energy Requirement, , is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight.For a person with a body mass of (kg), height of (m), age of (years) and Physical Activity , this is given by
Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk. [1]
