All About Fat Loss



There are so many questions about fat. What is it?  Why is it stored in different areas?  What is the most effective way to lose it?  Although most people spend a great deal of time and money trying to lose fat, it is vital to the proper function on your cells. Fat has a key role in the flexibility and structure of cell membranes, affects immune function, and is an energy reserve. Did you know that it has been estimated that a lean adult male stores 131,000 calories in fat? That is enough energy reserve to keep him alive for roughly 65 days. The majority of your fat stores are in the form of triacylglycerols in storage cells called adipocytes. Whether your body stores fat or releases it into the bloodstream is based on caloric supply and demand. When energy supply is high, insulin keeps fat inside adipocytes. During exercise or periods of fasting insulin is lowered releasing fat into the bloodstream where it is carried by proteins to cells where it can be broken down into ATP (energy for your muscles) or stored.

Now that we know what fat is and how it is stored, let’s look at what is the best way to burn already stored fat cells. As previously stated, fat storage and use is determined by an energy surplus or deficit. Meaning to lose fat, we need to create an energy deficit. Furthermore, insulin plays a major role in fat storage and release. The lower your insulin levels are (either by exercising or altering food intake) the more fat will be released and used as an energy source to meet energy demands placed on the body. This is why a lower carbohydrate diet is generally effective in weight loss (lower carbohydrates mean lower insulin levels).   

Exercise intensity also plays a role in fat loss. Research finds that we burn the most fat when exercising at low to moderate intensities. When exercising at high intensities the majority of your energy comes from the breakdown of carbohydrates instead of fat.  Now does this mean that exercising at a high intensity isn’t good for fat loss? Let’s not jump to conclusions. We also have to consider exercise recovery. After we finish exercising our bodies need to use more energy to help cells recover and replace lost glycogen. In short, our metabolisms are running at a much higher rate. And this happens at the most accelerated rate after bouts of high intensity resistance training. 

So, what is the most comprehensive attack against fat? The answer is an exercise program that alternates between high-intensity training and moderate-intensity training on different days while eating a lower carbohydrate-reduced calorie diet. This maximizes the body’s two ways of burning fat: in a single bout of exercise and in recovery. 

So there you have it..."Fat Loss" in a nutshell.  Still have questions?  Be sure to talk with one of our fitness professionals and/or nutrition specialists for more info.  Good luck!!
