"Doing more exercise with less intensity,"
Arthur Jones believes, "has all but
destroyed the actual great value
of weight training. Something
must be done . . . and quickly."
The New Bodybuilding for
Old-School Results supplies
MUCH of that "something."

I thought it was an interesting article.

That article is saying we get zero energy from stored bodyfat? That's ridiculous! It's there for energy for the body to run on, it's AFTER we use it for energy that it's excreted. Otherwise, we'd all die over night if we didn't have a belly full of food. Fat cells release FFA's (free fatty acids) into the blood when insulin levels are below their insulin sensitivity threshold, those FFA enter cells (muscle, organ, etc), and into the mitochondria of those cells where they can be used to form ATP for cellular energy.

Actual non-misleading explanation,

Fat is stored inside the fat cell in the form of triaglycerol. The fat is not burned right there in the fat cell, it must be liberated from the fat cell through somewhat complex hormonal/enzymatic pathways. When stimulated to do so, the fat cell simply releases its contents (triaglycerol) into the bloodstream as free fatty acids (FFA's), and they are transported through the blood to the tissues where the energy is needed.

A typical young male adult stores about 60,000 to 100,000 calories of energy in body fat cells. What triggers the release of all these stored fatty acids from the fat cell? Simple: When your body needs energy because you're consuming fewer calories than you are burning (an energy deficit), then your body releases hormones and enzymes that signal your fat cells to release your fat reserves instead of keeping them in storage.

For stored fat to be liberated from the fat cell, hydrolysis (lipolysis or fat breakdown), splits the molecule of triaglycerol into glycerol and three fatty acids. An important enzyme called hormone sensitive lipase (HSL) is the catalyst for this reaction. The stored fat (energy) gets released into the bloodstream as FFA's and they are shuttled off to the muscles where the energy is needed. As blood flow increases to the active muscles, more FFA's are delivered to the muscles that need them.

An important enzyme called lipoprotein lipase (LPL), then helps the FFA's get inside the mitochondria of the muscle cell, where the FFA's can be burned for energy. If you've ever taken a biology class, then you've probably heard of the mitochondria. This is the "cellular powerhouse" where energy production takes place and this is where the FFA's go to be burned for energy.

When the FFA's are released from the fat cell, the fat cell shrinks and that's why you look leaner when you lose body fat - because the fat cell is now smaller. A small or "empty" fat cell is what you're after if you want the lean, defined look.
