Why your BRAIN quits on Low-calorie Diets

IMG_9383From Jeff Volek PhD and Dr Stephen Phinney MD’s book, The Art and Science of Low Carbohydrate Living, we read,

“The brain is the spoiled child of the organ family. It can burn glucose or ketones (or a combination of the two) and it can’t burn fat. This is interesting because the brain itself contains a lot of fatty acids in all its membranes and myelin (although little or none as triglycerides), and the many types of brain cells all contain mitochondria that should be capable of oxidizing fatty acids. Another surprise about the brain is how much energy it consumes each day (600 kcal) despite weighing just 3 pounds. This is more than 10-times the average energy use per pound of the rest of the body, which explains why the brain has such a large blood supply (to provide fuel and oxygen and also to keep it cool).

The other important fact about the brain’s fuel supply is that it contains no reserve supply of glycogen, and because it can’t burn fat, it is absolutely dependent upon a minute-by-minute blood supply containing both fuel and oxygen to meet its needs. This

Why HIGH INTENSITY INTERVAL TRAINING is good for your heart from a fuel perspective


The health and fitness benefits of High Intensity Interval Training are well researched and established. Below we learn why from a fuel perspective.

From Jeff Volek PhD and Dr Stephen Phinney MD’s book ‘The Art and Science of Low Carbohydrate Living’ we read, “The predominant fuel preferred by your heart when you are not exercising is fat. The heart rarely uses much glucose, with the only exception being during a heart attack when a vessel is plugged and the oxygen supply to that part of the muscle is cut off or severely reduced. In that case, the small amount of glycogen in heart muscle is used anaerobically to make lactate.

And here’s one more bit of heresy about lactate. During exercise, a healthy and well-perfused heart actually takes up lactate from the circulation and burns it to CO2 and water. Lactate is preferred by heart muscle cells over glucose, and during endurance exercise, lactate can provide as much as 50% of your heart’s energy need.”


Lactate is produced in the working muscles during more intense exercise and is immediately used as fuel in the heart. This lactate not used by the heart is recycled by

How “Eat less. Move more.” Diets Actually FAIL and Slow Down Your Metabolism

I’ll bet you’ve tried the “Eat less. Move more.” diet at least once. Right?  It probably failed too. For most, it starts out okay. You’ll drop some pounds but then, over time, your food cravings are almost unbearable and the thought of doing one more stair routine, spin class or body pump class makes you angry. After all, everyone says it will work. All the hot after photos of these thin women or men with abs shows that it works.


“But wait, Michael!” you’re yelling at me. It seems to make sense. Eat less and burn more calories than you’re putting in your body and you have to lose weight. Everyone says
