E. Let’s Test the model with our first Observation
(a) A very fat person was very lazy and hardly did any work. Then he exercised, got leaner, and now he is very energetic.
Triglycerides, and adipose tissues stores energy, and they are stored in the body as fat. Therefore fat is just unutilized stored energy.
Therefore, Total Mass=Lean Mass+Stored Unused Mass. (i)
Total Potential Energy=(Actual Energy)+(Stored Energy) (ii)
The person is lazy. This means that:
Actual Energy< Stored Energy (iii)
Therefore, Lean Mass<Stored Mass. (iv)
Therefore, Lean Weight< Stored Weight (v) (use equation 2).
If anyone has to get rid of laziness, one has to then reduce stored energy to nearly zero(in equation ii) by utilizing the stored energy.
In order to reduce the Stored Potential Energy, we can add an extra variable called “Excess Used Energy.”
Stored Potential Energy=Stored Potential Energy-Excess Used Energy (vi)
So, Stored Fat ∝ Stored Fat-(Excess used Energy) (use equation 1b)
Energy can be used only by applying a force, which will increase if we increase acceleration(equation 3). So if you start walking or exercising, you are increasing the acceleration of the body, which will result in Energy utilization.
💡Insight
We intake energy through food. So, your energy loss through exercise has to be more than the energy gained by the food. On average one eats 2000 calories of food. If one does nothing and sleeps in the bed, then the body utilizes 75% of the energy. Therefore either you have to lose 500 cal energy through exercise or reduce food intake.
Now your observation fits into a raw model. The next step is to transform the mathematical model into a simple statement.
