First Law of Thermodynamics
The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed.
So in terms we can all understand. Calories are energy and it always exists. It cannot evaporate. So it is either in the form of fuel (food- body fat, muscle glycogen), Stored energy (your body) or heat (calories being burnt off). You are part of a system that includes your body and the food that you eat.
Calories = Heat = Energy. Simply put…When we add energy to the system, our bodies either store the energy or burn the energy. It is a balance.
It's simple math, really. The picture on the right shows how it works.
The Plate represents food intake or energy "in" (calories). The person in the middle is you and the amount of calories that you need every day to stay exactly where you are. The person on the far right represents the outcome.
1. If the amount of calories that you consume is equivalent to amount your body needs at your current daily requirement, you will see no change. 2. If the amount that you consume is greater than the amount you need on a daily basis you will get bigger. 3. If you consume less than what your body needs daily you will get smaller.
It i just science and eventually, while at times the rate of change will vary from person to personis different from person to person, science will prove itself.
*The rate at which your body burns calories at rest is called the RMR or Resting Metabolic Rate. The BMR includes your average daily activities (Basal Metabolic Rate)
In Our Next post we will discuss how to figure your BMR as well as how to "Set your thermostat" to burn more calories each day.
