Types[edit]

Make-up of food types needs to be imbedded from my previous writings

Quantities[edit]

The quantity required differs per person. This, since each person has a different genetic makeup (or Basal Metabolic Rate) (making them larger, smaller, ...) and depending on the function they have in society, they may also have different Physical Activity Levels.

Formula[edit]

We use the Harris-Benedict equation, which goes as follows:

  • Men: BMR = 66 + (13.7 X weight in kg) + (5 X height in cm) - (6.8 X age in years)
  • Women: BMR = 655 + (9.6 X weight in kg) + (1.8 X height in cm) - (4.7 X age in years)

Basal Metabolic Rate[edit]

Dietary reference values.png
Age in years kcal/d:
0 BMR:375 x PAL:1,40 = 525 TDEE
1 BMR:525 x PAL:1,40 = 735 TDEE
2 BMR:625 x PAL:1,40 = 875 TDEE
3 BMR:750 x PAL:1,45 = 1050 TDEE
4 BMR:825 x PAL:1,45 = 1196,25 TDEE
5 BMR:850 x PAL:1,50 = 1275 TDEE
6 BMR:900 x PAL:1,55 = 1395 TDEE
7 BMR:950 x PAL:1,55 = 1472,5 TDEE
8 BMR:1000 x PAL:1,55 = 1550 TDEE
9 BMR:1100 x PAL:1,55 = 1705 TDEE
10 BMR:1150 x PAL:1,55 = 1782,5 TDEE
11 BMR:1200 x PAL:1,55 = 1860 TDEE
12 BMR:1275 x PAL:1,55 = 1976,25 TDEE
13 BMR:1350 x PAL:1,55 = 2092,5 TDEE
14 BMR:1425 x PAL:1,55 = 2205,75 TDEE
15 BMR:1475 x PAL:1,55 = 2286,25 TDEE
16 BMR:1575 x PAL:1,55 = 2441,25 TDEE
17 BMR:1625 x PAL:1,55 = 2518,75 TDEE
18 BMR:1675 x PAL:1,55 = 2596,25 TDEE

Note 1: between 0 and 9 months, the caloric intake actually needs to be added to the pregnant female in question. A close-up of the exact caloric requirements per 3 months are:

  • Age in months -- kcal/d:
  • 0-3 -- BMR:392,85 x PAL:1,40 = 550 TDEE
  • 4-7 -- BMR:464,28 x PAL:1,40 = 650 TDEE
  • 7-9 -- BMR:500 x PAL:1,40 = 700 TDEE

Note 2: For the dietary reference values for people with an age above 18, the extra number of years above 18 are multiplied by 6 (average 6,8 and 4,7 of male/female Harris-Benedict formula) and added to the BMR. Thus, older people will generally require a bit more calories than younger people (thus contrary to popular beliefs), but it is likely that the end result will nonetheless be smaller, since older people often become less active, and thus the PAL will generally reduce.

Note 3:

  • TDEE means Total Daily Energy Expenditure
  • BMR means Basal Metabolic Rate
  • PAL means Physical Activity Ratio

Physical Activity Level[edit]

Mean activity level[1] P.A.L. range Average P.A.L. Description of activities [2]
Sedentary 1,175-1,375 1,2 No exercise, desk job; reading, watching TV, writing, calculating, playing cards, listening to music
Lightly active 1,375-1,550 1,4 Little exercise, desk job; sewing, knitting, playing piano, cooking, washing up, ironing, writing, calculating, playing cards, dressing, undressing, showering, ...
