Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How much energy is stored in 1kg of body fat compared to 1kg of glycogen
A
Half as much
B
Same amount
C
Twice as much
D
one sixty fourth as much
E
one tenth as much
Explanation: 

Detailed explanation-1: -And so logically one kg of glycogen would give four times 1000, Which equals 4000 chemicals of energy. Um And so one g of fat Gives us nine kilocalories of energy. Um and one kg Is once again 1000 g. So during the conversion we got nine times 1000 Equals 9000 cake house of energy.

Detailed explanation-2: -There are 7, 700kcals (kcal=calorie) worth of energy in 1kg of fat. That means in order to burn 1kg of fat, you must have a calorie deficit of 7, 700. Considering the average daily intake can be anywhere from 1, 800-2, 400kcals, it takes some time to burn that fat.

Detailed explanation-3: -1kg of fat is 7, 700 calories. To lose 1kg of fat, you need to be in a calorie deficit of 7, 700 calories.

Detailed explanation-4: -The body has different forms of energy storage, but the most efficient is fat. Fat has the greatest energy density. Glycogen is another vital form of energy storage in the body, but it is less efficient compared to fat because it gets bound to water molecules during storage.

Detailed explanation-5: -The energy density of the body fat mass change, F = 39.5 MJ/kg is the same as the energy density of fat.
