I. Evaluation of the daily energy consumption

A. Basal metabolism is estimated according to Table 12.

B. Energy consumption for digestion of nutrition — 10 % of basal metabolism.

C. Energy consumption for all kinds of activity:

1. Estimate basal metabolism per hour. Basal metabolism per hour = Basal metabolism: 24 hours.

2. Estimate energy consumptionfor all kinds of activity: energy consumptionfor activity = (Basal metabolism per hour) x (duration of activity) x (coefficient of activity). The coefficient of activity is indicated in Table 13.

3. Sum up all the energy consumption for the activity (for all twenty-four hours) — (Table 3).

D Daily energy consumption = energy consumption for digestion of nutrition + energy consumption for all kinds of activity

	Age (in years)	Basal metabolism (00) kcal of energy
Men	10-18	(16.6 х W) + (77 х H) + 572
	18-30	(15.4 х W) + (27 х H) + 717
	30-60	(11.3 х W) + (16 х H) + 901
	older than 60	(8.8 х W) + (1128 х H) + 1071
Women	10-18	(7.4 х W) + (482 х H) + 217
	18-30	(13.3 х W) + (334 х H) + 35
	30-60	(8.7 х W) + (25 х H) + 865
	older than 60	(9.2 х W) + (637 х H) — 302
Note: W- weight in kilograms, H — height in metres

Task

A man aged 20 is 60 kg in weight, 1.7 m in height. His work during the whole twenty-four hours is as follows: classes in a clinic — 5 hours, attendance of lectures — 3 hours, going by transport — 2 hours, work on a computer — 1 hour, preparation for classes — 4 hours, sleep — 9 hours. Calculate his energy consumption for twenty-four hours.

Solution

1. Calculation of the basal metabolism (Table 12).

The basal metabolism = (15.4 х W) + (27 х H) + 717 = 924 + 45.9 + 717 = 1686.9 kcal.

Basal metabolism per hour = 1686.9 kcal: 24 hours = 70.29 kcal per hour.

2. Calculation of the energy consumption for all kinds of activity (Tables 13, 14).

 

№ №	Activity	Duration of activity (in hours)	Coefficient of activity	Basal metabolism per hour (kcal per hour)	Energy consumption for the activity
1.	Classes in a clinic	5	2.2	70.3	5´2.2´70.3 = 773.3
2.	Attendance of lectures	3	1.9	70.3	3´1.9´70.3 = 400.7
3.	Going by transport	2	1.5	70.3	2´1.5´70.3 = 210.9
4.	Work on a computer	1	1.6	70.3	1´1.6´70.3 = 112.4
5.	Preparation for classes	4	1.6	70.3	4´1.6´70.3 = 449.9
6.	Sleep	9	1	70.3	9´1´70.3 = 632.7
Sum up all the energy consumption for the activity (for the whole twenty-four hours) = 773.3 + 400.7 + 210.9 + 112.4 + 449.9 + 632.7 = 2579.9 kcal

 

3. Daily energy consumption = energy consumption for digestion of nutrition + energy consumption for all kinds of activity.

Daily energy consumption = 168.69 + 2579.9 = 2748.6 kcal

The answer: The daily energy consumption = 2748.6 kcal

II. Evaluation of the necessary quantity of nutrients according to the amount of the daily energy consumption

Caloric content of protein makes up 12-14 % of common caloric content of nutrition.
