The body adapts, but we must make it adapt.Let’s talk thermodynamics.

In my own “athletic background” ( if you can call it that) I trained for performance. I lost some weight over the course of 7 marathons. But it wasn’t necessarily from running. I started marathon training at age 35. I’m 42(43- in about 7 weeks). So yes, my body is different today from when I first started training.

As a personal trainer, 100% of my clients have not come to me with marathon training goals. Their goals are based around aesthetics, and getting strong. And thats great. A big concern early on is nutrition. Here’s where I have to explain things carefully. One of my recent blogs is about the difference between personal trainers, nutritionists and registered dietitians. So if you had a chance to read that you’d know I’ll never tell a client that she/he can’t have a particulate food. Why?

Because it isn’t necessarily about a particular food thats holding an individual back from their goals. it’s more about that individual having a better understanding of what’s going in vs what’s going out. Now lets talk a little science.

Thermodynamics is a branch of physics that researches how heat energy is converted into other forms of energy, and how it affects our body, (food just so happens to be the human body’s source of energy/ calories, duh) “Thermal” just pertains to the level of heat. Remember our bodies are machines. And machines need a bit of heat to rev up (hey theres a reason why the body temp is 98.6 degrees right?) .Heat energy transferred between 2 systems can/ will cause the that source of heat to be converted. But that heat energy it cannot be created or destroyed.

The basic component of any food we consume is a calorie(regardless of the macronutrients it comes from). A calorie by definition is a unit of “Heat energy”. When we eat, that energy source is converted via a molecular process, and released into our bodies to be used for energy. If we don’t burn it off, it’s stored as body fat.

As the first law of thermodynamics states, “energy can neither be created or destroyed “

Ie:

The body adapts, but we must make it adapt. Nobody is above the rules that make up body composition.
