Where E falls down is that he read something once and either didn't read the entire article or he forgot what he didn't want to remember.
Had to go back and dig into some studies on metabolism. While digging this quick discussion popped up. This is Kreps cycle stuff and there are dang few who understand it completely.
http://sportsmedicine.about.com/od/sportsnutrition/a/Energy_Pathways.htmHunting last time I looked was essentially an aerobic endurance activity and thus fat plays the roll of the primary energy source. Fat wins the long race.
E also said lactic acid is produced when the body runs out of carbs. Wrong, lactic acid it produced when the body runs low on oxygen.
Another article relating to the aerobic and anaerobic metabolic pathways.
Why does lactic acid build up in muscles? And why does it cause soreness?

Stephen M. Roth, a professor in the department of kinesiology at the University of Maryland, explains.
As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to shuttle more oxygen to our working muscles. The body prefers to generate most of its energy using aerobic methods, meaning with oxygen. Some circumstances, however, --such as evading the historical saber tooth tiger or lifting heavy weights--require energy production faster than our bodies can adequately deliver oxygen. In those cases, the working muscles generate energy anaerobically. This energy comes from glucose through a process called glycolysis, in which glucose is broken down or metabolized into a substance called pyruvate through a series of steps. When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown--and thus energy production--to continue. The working muscle cells can continue this type of anaerobic energy production at high rates for one to three minutes, during which time lactate can accumulate to high levels.
A side effect of high lactate levels is an increase in the acidity of the muscle cells, along with disruptions of other metabolites. The same metabolic pathways that permit the breakdown of glucose to energy perform poorly in this acidic environment. On the surface, it seems counterproductive that a working muscle would produce something that would slow its capacity for more work. In reality, this is a natural defense mechanism for the body; it prevents permanent damage during extreme exertion by slowing the key systems needed to maintain muscle contraction. Once the body slows down, oxygen becomes available and lactate reverts back to pyruvate, allowing continued aerobic metabolism and energy for the body�s recovery from the strenuous event.
Addition: E may be a carb addict and seldom gives his body the chance to run on fat and thus thinks the way he does. Most of Americans today probably are addicted to the ups and downs of relying primarily on carbs for fuel. Carbs certainly play an important roll and I don't think carbs can be blamed for the obesity problem we have today. The problem is most don't move enough nor have control of the calories they consume.
There is much to dislike about the reality survival TV programs. However one thing to observe, is the amount of red meat and fats those who can stay out and keep going consume.
