Exercise and Fat Burning

Yay! I’m down another 0.4 pounds today!  That’s a total of 20.6 pounds lost with 59.4 pounds to go to reach my goal!  And, I had pizza for supper last night!

Exercise and fat burning can be a complicated and confusing topic, so we’re going to try to simplify it.

We are what we eat – literally.

Much of what we eat is converted into our body’s tissues.  Food is digested into molecules, which are then rearranged into usable substances that your body uses to build and/or repair tissue.  However, most of the food you eat is used as fuel to run your body.

fat burning     Your body is a fuel burning machine.  We have trillions of “little furnaces” that create energy.  What happens when your car runs out of gas?  Or when the electricity goes out?  Your appliances aren’t much good are they?  Machines need the right source of energy to work, a fuel of some sort, and the better quality the fuel, the better the performance.  It’s the same with your body.  Your “machine” needs fuel to perform its bodily functions.  Each and every one of your cells has a little factory inside that creates energy.  Every little cell in your body has its own little furnace that needs to be fed constantly for it to create the energy it needs to function.  And healthy, energized cells = a healthy, energized body.

Let’s focus on the fuel needed to move our muscles.  Obviously, food is our fuel, but it has to be converted into a usable form.  Your body can use:

*Glucose – from carbohydrates.  Available in your bloodstream from foods eaten, or stored in your liver and/or muscles as glycogen.  This is the only source of fuel your brain can use, and it uses lots of it.  Your brain can’t burn fat.

*Fatty acids – from fats.  Stored in fat depots like your hips, abdomen, thighs, breasts, all those jiggly parts.

*Amino acids – from protein.  To use protein as fuel, your body would have to tear down existing tissue, like muscle, which is not a good thing.

Are these fuels equal?  No.  Your body has a definite preferred source of energy – fat is the winner.  Why?  Because with fat you get more bang for your buck.  Fat provides a little more than twice the energy value of carbohydrates and of protein.  Think of fat as the “high octane” gas versus “regular” gas for your car.  That is great news for those of us who want to get rid of excess body fat, right?  Well, yes, but . . . If your body can’t get to your fat stores (for many reasons), then glucose is the next best thing.  Protein is only used as a very last resort.  So the big question is –

How can we speed up fat burning?  And that we’ll answer tomorrow.

Come join me on my weight loss journey!  I’d love to have you along!

Have an awesome day!
