So you’ve been eating well and working out, and then one day, you put your jeans on and they feel loose and you are a happy camper. Did you ever wonder where all that fat and inches went?
The short answer is : your body converted the molecules in fat cells into usable forms of energy and therefore shrunk the fat cells.
Want more details? Well, here it goes:
Calories measure the potential energy in food you eat in the form of fats, proteins and carbohydrates. If our bodies were cars, energy would be the gas to keep everything running. The more you work, the more energy is needed, right? The faster the car goes, the more gas it uses.
Some calories are needed to digest food. Once the food is broken down into its respective parts of carbohydrates, fats and proteins, the body uses the remaining energy, or it converts it to fat for storage in fat cells. Interestingly enough, fat cells don’t disappear when you get smaller–hey just change their form, like water and steam.
Here is the next interesting part:
We know that hormones regulate the blood sugar levels, right? These hormones also activate lipase, an enzyme in the blood vessels. Next, lipase ignites fat cells to release triglycerides, which are the micromolecules that make fat cells fat. When they receive the signal from lipase to exit the fat cells, the triglycerides break up into their respective components and enter the bloodstream for use. The liver snatches up the glycerol to break it down for energy, and some of the fatty acids move to the muscles that can farm them for energy as well.
This action of breaking down triglycerides into usable energy is called lipolysis. Once inside the power source or muscle or liver cells, the components of the glycerol and fatty acids are shuffled and reshuffled to harness their energy potential, producing heat, water, carbon dioxide and ATP, which hauls potential energy in its molecular bonds for use when we exercise. So now, the body relieved fat cells of some glycerol and fatty acids, and the fat cells are smaller.
How cool is that?
