Short Answer

Expert verified

As a result, if a person wishes to shed $1$ pound of fat, which is $15$ percent water, he or she must lose $3500$ kcal.

Step by step solution

Given Information.

The Following are the given information as:

Body fat $= 1 l b$

water present in body $= 15 %$

To find the Kilocalories found in body

Explanation

The proportion is calculated as follows: $15$ mass units of water contains $100$ mass units of fat.

As a result, $1 l b$ of body fat comprises $0.85 l b$ of fat, which is $15$ percent water. Then, $1 g$ of fat contains $9 K c a l$ ,

Hence the equation is same.

$1 g F a t = 9 K c a l$

Find the Kilocalories.

We're given a weight in pounds, which we must convert to grammes. Egalitarianism exists.

$1 lb = 454 g$

These are the factors of conversion

$\frac{1 lb}{454 g} and \frac{454 g}{1 lb}$

As a result, using the relevant conversion factors, the number of kilocalories that must be lost can be computed.

$0.85 tbfat \times \frac{454 gfat}{1 fbfat} \times \frac{9 kcal}{1 gfat} = 3500 kcal$
