Consider your body as an open system. For five days in row record your energy intake as well as your body mass. The measurements of body mass should be done twice a day, in the mornings and evenings at the same time for all five days.

Use the First Law of Thermodynamics to analyze your body mass. Please note that the energy surplus is converted to a fat $($mass$).$ Plot your weight versus time $($days$)$ and try to explain the graph.

Answer the following questions:

$1.$ Does your body mass clearly correlate to your recorded energy intakes? Explain and prove.

$2.$ How accurately can you predict your body mass loss from the energy intake analysis? What are the difficulties in predicting body mass?

$3.$ Identify three most energy consuming activities and three the most energy rich intakes for five days recording period.

$4.$ Based on the thermodynamics analysis, what do you think is the best diet for you in case you want to lose some weight? Explain.

$5.$ Why is it so difficult to reduce body mass? Answer it from the thermodynamics point of view?

NOTE: Please if you do not know the answer do not answer this. This is the third time I post this question. Just take random numbers for body mass, energy intake. Just show me the way of answering questions. I have real numbers so I will plug numbers.
