Fat Burner vs. Sugar Burner

  • Do you feel either wired or tired after eating?
  • Do you need to snack between meals to keep your energy up?
  • Do you hit a wall during work-outs?
  • Does your energy fluctuate dramatically during the day, often leaving you flat?
  • Do you experience strong food cravings?

If you answered yes to any number of these, chances are your body is primarily using glucose rather than fatty acids for fuel.

A fat burner feels no rise or slump in energy after meals, can go long hours without food – even fasting with ease intermittently – and has sustained endurance during prolonged workouts. Further, a fat-burner has level energy from sun-up to sun-down and does not experience compelling food cravings.

Not only does being a sugar-burner make you feel miserable, it also damages your health. Here’s a brief physiology lesson. Every cell produces energy to carry on life. The process of converting fuel to energy is called the Krebs cycle. Acetyl coenzyme A is a necessary molecule for the Krebs cycle. The breakdown of glucose to form pyruvate is one way to make this molecule, but it can also be created if fatty acids go through a process called beta oxidation.

You don’t need to remember that. The important point is that the body’s preferred pathway is beta oxidation because it requires one less step and produces 33% more energy.  

So if the body wants to burn fats, why are you burning sugars??? Because the fats aren’t accessible! Enter insulin. This is a masterfully-designed hormone that performs its labor well, which is to carry glucose to various parts of the body – the brain for immediate use, the liver for conversion to glycogen, the muscles for quick bursts of energy, and to adipose (fat) tissue for long-term storage.

When you eat a meal that is roughly 1/3 protein, 1/3 fat and 1/3 carbohydrate calorically, the sugars from the carbohydrates will enter the bloodstream at a nominal rate, and you will be able to utilize them as they are made available. But if you double the amount of carbohydrates, and halve the protein and fat content, sugars surge into the bloodstream.

Humans were never designed for such high loads of glucose, which wreak havoc if blood levels remain chronically high. There is a sudden emergency to lower blood sugar. The body can’t possibly use all that glucose at once for energy, so it releases a deluge of insulin to compensate. Insulin whisks the glucose into storage and prohibits fat stores from being mobilized. Your cells are left to burn only glucose.

One solution to the sugar burner metabolism is to adjust your ratios of carbs, fats and proteins. The next time your body sends a signal in the form of a craving that it needs energy, feed it something that will counter an insulin spike and initiate a fat burn.
