The evolution of Paleo diets: Hunting the roots of this food movement

It seems everyone has an opinion on the Paleo diet. Some herald it as the the saviour to the human race while others warn of its potential dangers.hunter gatherer

It is a topic that polarises many people, and it certainly has created many misconceptions.

But who do we believe?

Many groups and individuals have vested interests. From┬ácelebrity chefs that have benefited from the paleo way by creating an empire of cookbooks and programs, to large organisations that receive funding from the food industry who may be feeling the pinch of decreased sales. (more…)

Slow the ageing process with a V8 metabolic engine

Slow the ageing process with a V8 metabolic engine

March is a month of mayhem in Adelaide. With the festival coming and going and the V8’s long gone from our streets, I have sensed a great deal of fatigue in those who have tried to keep up with the frenetic pace.

It is like we need a tank of that high octane fuel to get us through to Easter!

However, with a few simple tweaks of our metabolic engine we may be able to develop a machine powerful enough to see us through these busy times with plenty of energy in reserve. (more…)

What’s With Carb Loading?

Having recently completed my first official ‘mini ultra’ 50km marathon, one of the most common queries I received was about when I was going to do my carb loading, so I thought I would put forward my opinion on this concept!

Carbohydrates are stored in the body, and unlike fat, storage space is limited. Our muscles are the primary storage site, however our liver has a small capacity to draw upon for various functions. Upon requirement of energy, stored carbohydrate (in the form of glycogen) is converted into glucose and utilised as fuel.

Now, the body uses two primary fuel sources – carbohydrates and fats. For rapid production of energy, carbohydrates provide the bulk of the fuel. This occurs predominantly during high intensity exercise. At low and moderate intensities, fats contribute a greater proportion of fuel as the process for breakdown is more complex and requires oxygen. At any given time the body is using a mix of these two sources but the contribution of each is dependant upon what we are doing.

The average human body can hold somewhere between 1600-2400 calories of energy from glycogen.
