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 m {\displaystyle m} (kg), height of h {\displaystyle h} (m), age of a {\displaystyle a} (years) and Physical Activity PA {\displaystyle {\text{PA ...
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.
Nutripoints [9] is a food-rating system which places foods on a numerical scale based on their overall nutritional value. The method is based on an analysis of 26 positive factors (such as vitamins, minerals, protein and fiber) and negative factors (such as cholesterol, saturated fat, sugar and sodium) relative to calories.
"The primary factors that determine how many calories someone needs include birth sex, age, genetics, body size, and daily activity level,” says Anya Rosen, M.S., R.D., a New York-based dietitian.
(For example, if the calculator determines your calorie goal is 2000 calories, subtracting 10% or 200 calories would give you a goal of 1800 calories per day for weight loss.)
Some such comparisons can be the glycemic index and the overall nutritional quality index. When the density is defined in proportion to energy contents, nutrient-dense foods such as meats, fruits and vegetables are the opposite of energy-dense food (also called "empty calorie" food), such as alcohol and foods high in added sugar or processed ...
Specific dynamic action (SDA), also known as thermic effect of food (TEF) or dietary induced thermogenesis (DIT), is the amount of energy expenditure above the basal metabolic rate due to the cost of processing food for use and storage. [1]
A moderate energy density would be 1.6 to 3 calories per gram (7–13 kJ/g); salmon, lean meat, and bread would fall in this category. Foods with high energy density have more than three calories per gram (>13 kJ/g) and include crackers, cheese, chocolate, nuts, [10] and fried foods like potato or tortilla chips.
