During pregnancy, a woman's mass increases by about 12 kg (26 lb). [39] The European Food Safety Authority recommends an increase of 300 mL per day compared to the normal intake for non-pregnant women, taking the total adequate water intake (from food and fluids) to 2,300 mL, or approximately 1,850 mL/ day from fluids alone.

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.
Beyond upping your knowledge (and appreciation!) for how your body works, knowing your BMR can help you reach your health and fitness goals. Here are a few benefits of your BMR: Understanding ...
An abnormal basal metabolic rate is not necessarily indicative of disease; a number of physiological factors can alter the BMR by influencing cellular metabolic activity. [1] For instance, males are more likely than females to have a high BMR, and in women, the BMR may rise to abnormal levels during pregnancy or lactation. [2]
Your rate of energy expenditure at rest is known as your basal metabolic rate (BMR). In simpler terms, this is the number of calories your body needs to just survive and perform basic tasks ...
The Institute of Medicine equation uses a different approach to most others. The equation doesn't measure basal metabolic rate, but uses experiments based on doubly labelled water. The scientists at the Institute of Medicine said in their report that the factorial method tended to underestimate calorie expenditure.
Basal metabolic rate (BMR) accounts for about 60% of the calories you burn each day. To calculate your BMR, you should use the Mifflin-St. Jeor equation, which is the most accurate. Knowing your ...
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.
