The Energy range which will allow the woman to start to lose some weight is below 2400 kcal/day. That is option A.
<h3>Calculation of estimated energy requirements</h3>
Estimated Energy Requirement is defined as the average energy intake that is needed to maintain the current weight of an individual. Its value depends on:
age(A)
gender,
weight(W)
height(H),
level of physical activity(PA); and
physiological state (e.g., pregnancy, lactation, illness).
To calculate the energy range of a female, the formula below is used:
Energy range = 354 - (6.91 × A) + PA × [(9.36 × W) + (726 × H)]
Where A = 22 years
W = 200lbs= 91kg
H = 5ft = 1.5m
PA = 1.12
Therefore Energy range = 354- (6.91×22) + 1.12 × [(9.36×91) + (726 ×1.5)]
Energy range = 354 - 152.02 + 1.12 × (851.76 + 1089)
Energy range = 354 - 152.02 + 1.12 × 1940.76
Energy range = 201.98 + 2173.6512
Energy range = 2375.6kcal/day
Therefore, the Energy range which will allow the woman to start to lose some weight is below 2400 kcal/day.
