How many calories do need women

The number of calories needed a woman would depend body built, lifestyle and even genes by many factors such as weight, height, age. Pregnancy also contributes to the need for calories.

A further important factor experts hold in computer science the right amount of calories, a woman would need is your basal metabolic rate.

Basal metabolic rate(BMR)

Basal metabolism varies between men and women. It is the amount of energy or calories, the body needs work it to keep the rest. Scientifically, the human body needs a minimum number of calories to keep the millions of chemical reactions, eyes, lungs, heart, liver, etc. to keep kidneys healthy order. This is the basal metabolic rate. For example, a 55-year-old woman weighing 130 lb (59 kg) and 5 feet 6 inches (168 cm) tall would a BMR of 1,272 kcal per day.

More than half the calories of most women needed fuel pump this basic body functions and it varies between obese and thin women. Computing BMR include weight, height and age and heat production alone. The BMR is about 60-70% of total calories used.

Nutritionists use three complicated equations to calculate the BMR:

Harris-Benedict Equation:

Daily calories (kcal) = [447.6 + 9.2 (weight in kg) + 3.1 (height in cm) 4.3 (age)] x 1.7

Total energy expenditure method:

Daily calories (kcal) = weight in kg X 40 kcal / kg

Activity factor

Daily calories = weight in kg x activity factor (AF)

(AF = 13 for light activity; AF = 16, for moderate activity; 19 For heavy activity = AF and AF = 22 for extraordinary activity)

Nutritionists as a guide use the first two formulas to calculate basic calorie needs. Additional calories used in exercise calculate. The latter calculates calories different body weight must on the basis of level of activity.

The proper assessment of how much calories do specifically needs a woman is the work of a physician and nutritionist.

Essential components of a healthy diet for a woman:

50 to 60 percent carbohydrates

20 to 30 percent protein

20-30% fat

Enough calories and a daily multivitamin
