calculated above using her basic BMR (130 x 10), which turned out to be 1,300 calories. Now, to factor in her activity level and digestion needs, simply follow steps 2 and 3 from the General Calculation: Activity level of 30% 1,366 x 0.30 = 409 calories 1,366 + 409 = 1,775 calories Digestion 1775 x 0.10 = 177 calories 1775 + 177 = 1,952 calories As you can see, you can use either the general calculation or the Harris-Benedict equation to get an appropriate approximation of your daily caloric expenditure. Using our example person, you can see that the difference between using the two calculations is only 93 calories (1,952 calories – 1,859 calories = 93 calories).

What humans actually need – the basics Major Factors that Affect Daily Caloric Need: Although these two equations can give you a relatively true representation of your total daily caloric expenditure, there are some other factors that can affect your BMR, either negatively or positively. Age BMR decreases by 2% for every decade beyond the growth period, which is generally age 20. Sex Men generally have more muscle than women, and lean muscle mass burns calories while fat mass doesn’t burn any calories. Genetic Build Tall, thin people generally have higher metabolisms than short, heavy people. Malnutrition Eating too few calories, like when dieters severely restrict calories, slows down the metabolism, by up to 30%. Thyroid Disorders Since the thyroid regulates the metabolism, disorders of this organ affect metabolic rate. In people with hyperthyroidism (the thyroid produces too much hormones), metabolic rate is increased. Those with hypothyroidism under-produce the hormones needed to stimulate the metabolism, so their BMR decreases. Both hyper- and hypothyroid problems affect whole body health negatively. Pregnancy Elevates BMR, which increases caloric need. Pregnant women generally need about 300 extra calorieer day.

What humans actually need – the basics Weight Loss and Calorie Requirements Using the chart, you can determine the calorie requirement for your target weight, then cut back your calorie intake accordingly. For example, you can see in the women's chart that a moderately active woman weighing 160 pounds burns about 2,200 calories per day. For a 140 pound woman the figure is about 2,050 calories. So, cutting back about 150 calories per day (2,200 minus 2,050) will eventually bring about a 20 pound weight loss, from 160 to 140. Another way of approaching weight loss A pound of fat contains about 3,500 calories. So, to lose a pound of fat in a week, you need to one of the following three things: 1. Decrease your food intake by about 500 calories a day. 2. Increase your calorie-burning activity by about 500 calories a day. See the calorie burning chart below.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
