What is the Harris Benedict equation formula?

B2/V2 is the measure of aerobic power. B2 is the body’s basic metabolic rate, or the amount of energy (kcal) the body expends during rest or exercise. V2 is “the volume of O2 consumed per minute, usually expressed in liters per minute.”

How many calories should I be eating to lose weight?

About what amount of calories should you be eating for a healthy lifestyle? If you need 2,500 to 3,000 calories to maintain a healthy weight, then you need about 3,000 calories to lose one pound per week. Remember that one gram of fat is equal to 1 calorie (1,600 for most people).

What is BMR female?


The basal metabolic rate is defined as the amount of energy an individual requires to stay alive and maintain vital functions. When you are in a resting or sedentary state, your energy costs are low, even when you are burning calories.

Furthermore, how do you calculate activity factor?

Activity factor is the factor by which you multiply the volume of one period to find the average daily production. So if I am making 40 molds per hour, then my hourly activity factor is 0.25 times 40 molds per hour.

Is resting metabolic rate accurate?

Metabolic rate is typically measured by weighing a person before and after fasting. The weight measurement is called the “resting metabolic rate.” For this reason, the RMR is often used as a measure of a sedentary person’s fitness level.

Also know, what is the Harris Benedict equation used to calculate?

Harris-Benedict or HBS is a statistical technique for determining a person’s metabolic rate from a known body weight and body weight.

How do you calculate ideal body weight?

A good average weight for men is between 140 and 165 pounds (66 and 77 kilograms), depending on height, and for women between 100 and 120 pounds (45 to 55 kilograms). Ideal body weight for men and women with a BMI of 25-29 is between 139 and 164 pounds (66 and 77 kilograms).

What is physical activity factor?

Physical activity factor (PAF) is a dimensionless quantity that represents the level of physical activity of a person who is physically active. PAF is expressed in units of the intensity of physical activity (BORG-6) and ranges from 0 to 100. Higher values reflect lower levels of physical activity.

What is PA factor?

The PA factor is a group of proteins in the human body responsible for the maintenance of body temperature. The PA factors are proteins that in some way regulate body temperature by changing the concentration of heat generated by the body.

How many calories do I burn in a day?

A person burns 500 to 1,000 calories a day depending on activity. That’s how many calories you use when you are at rest. If you are a moderately active person (working at 50% the recommended level or more), you can burn more calories on a daily basis than someone less active.

Should you eat below your BMR?

People often confuse their personal energy needs (aka their individual resting metabolic rate) with their “daily requirement intake” (aka their daily maintenance caloric need). However, they are different concepts with important differences in how much fuel can be produced and stored in the body. The BMR is the baseline amount of calories you need per day in order to function.

How do I work out my resting metabolic rate?

To calculate your specific metabolic rate, the formula is MET = 3.5 x Weight + (9.7 x age – 161.0). For example, if you weigh 200 pounds and turn 25, your MET (metabolic equivalent of task) is 33.5. Calculate your RMR by subtracting 1MET from the actual MET performed.

What is a good BMR?

A: A basal metabolic rate (BMR), also known as the energy expenditure of resting tissue, is a person’s minimum metabolic demands for basal activity and varies depending on factors such as age, size, and activity level. In short, the BMR is the amount of energy needed to carry out basic activities of daily living. The number is expressed in calories per day (or per kilogram of body weight per day for overweight people).

How do you calculate your basal needs?

Basal needs. For a normal adult male at rest, the US DRI for carbohydrates (based on the total protein and fat in a daily diet) is: 225 grams/day

What is moderately active?

Physical activity is any vigorous physical activity that gets your heart rate up. The types of activities considered physically active include swimming and tennis. On the other hand, walking or sitting is not a physical effort, and it’s a good form of physical activity. Moderate exercise is similar but it’s harder than mild exercise.

What is the Mifflin equation?

Mifflin’s equation is an equation for a line parallel to the axis of abscissa. To find points (x, y) on the line, set y = mx + b. To find points (x, y) on the line, set x = my + b.

What is BMR used for?

BMR or basal metabolic rate shows how much energy your body needs to maintain your body at rest. This is the same as your daily caloric expenditure (basal metabolism = BMR x 365) minus any non-measured expenditure or energy intake (e.g. food). When you spend more energy than your BMR, you start to lose weight.

How do you calculate caloric needs?

How to calculate your caloric need? The best method you need is to take your bodyweight and multiply it by 30. This will give you your daily caloric needs. Remember to eat more protein than carbohydrate and fat. You should eat until you’re hungry or satisfied but stop eating if your hunger meter is still at 50.

Which BMR equation is best?

The best estimate from the different BMR equations, including the Harris-Bollinger equation, is about 1246 kJ (275 calories) per resting day; if the equation for your BMR is 1020 kJ (221 calories) per resting day, then you’re burning more calories than your rest BMR and it is recommended to increase your caloric intake to prevent weight gain.

What is the average BMR?

It depends on gender and height, but typical values range from 1500 to 2000 calories. The amount and type of food you eat, the intensity of your exercise, and other factors also determine the energy you actually burn in a day. Your BMR can be up to 350% higher if you add regular activity.

What is the unit for BMR?

The metric unit (derived from the word metric ) is the kcal. The American system is the only system that currently uses the SI system. If the kilogram was based on the same principle as other units, e, then the kilogram would equal (4.2 lb) × (9.819 pounds) ÷ 1000 = 4.19 lbs.

Subsequently, one may also ask, how accurate is the Harris Benedict formula?

The answer is no. The formula has been used since it was created and is used by many researchers who use it. The formula has also been used as an assessment, especially for patients receiving dialysis.
