Many biological terms are used and may be difficult to understand. I have written this article in the best way possible for all to understand. Please leave me a comment if you have any questions regarding this article and I’d be more than happy to assist you with answers.

The purpose of this article is to:
1. Explain why the recommended daily intake of carbohydrates (CHO) is important for low intensity (long duration) exercise.
2. Explain why the recommended daily intake of carbohydrates (CHO) is important in regards to fat loss.

Below is the biological process of what happens within the human cells when the recommended daily intake of carbohydrates is not met.

Carbohydrates is known as a sugar and is absorbed from food when it reaches the intestines. This sugar travels in the blood as glucose, however can also be stored in the human muscles and liver as glycogen. If you do not eat carbohydrates then you will have decreased carbohydrate/ glycogen stores which will decrease the rate of glycolysis. Glycolysis is the breakdown of glucose to pyruvic acid which is then converted to Acetyl-CoA and occurs in the cytoplasm of the cell. Hence, by decreasing the rate of glycolysis you will decrease the quantity of pyruvic molecules being made. So by decreasing the quantity of pyruvic molecules being made, we are now decreasing the quantity of “material” to make the intermediate substrates of the “krebs cycle”. The krebs cycle occurs in the mitochondrial matrix of the cell and is where energy is made from both carbohydrates and fats. Both carbohydrates and fats are converted to a substance known as Acetyl-CoA which goes through the krebs cycle to make energy. If there is a decreased quantity of “material” to make the intermediate substrates of krebs then the functional rate of krebs is inhibited. Now we mentioned before that krebs is where energy is made, so if the krebs cycle is inhibited then we can’t make energy.

So now your asking… “well how is this related to fat?”

A process known as lipolysis is the breakdown of fatty free acids into acetic acids. Acetic acid is converted to Acetyl-CoA which then needs to go through the krebs cycle so it can be converted to energy as i mentioned before. However since the krebs cycle is inhibited due to not eating enough carbohydrates, the Acetyl-CoA from fats has nowhere to go and therefore fat is not being burned and energy is not being made.

Having said all this, the quantity of energy being made from fat is dependent upon the rate of carbohydrate metabolism.

To explain the purposes again…
1. The main fuel used in low intensity (long duration) exercise is fats, and therefore carbohydrates is required in order to keep the krebs cycle active so fats can be processed into energy for this type of exercise.
2. In order to burn fat for fat loss, the fats need to go through the krebs cycle. So once again carbohydrates is needed to keep the krebs cycle active so fats can be burned for fat loss.


My life and this blog…

In 1988 at the age of 2.5 years I was diagnosed with a kidney tumor. After failing several operations and treatments it was decided the best option was to remove the left kidney and undergo chemotherapy for 6 months. After a heavy operation and intense treatment I was cured of cancer for good. In return for life (due to chemotherapy) I lost my hearing in 1989 and developed cardiac complications in 1999. I will never forget the day I was sitting in the office, staring strait into the eyes of the doctor, clinging onto hope for life, waiting to hear weather I would live or die… A moment later words were spoken “Paul, you have just under two years to live…” For the next two years I battled through life striving to do everything I could to stay alive but everything was downhill. Between 1999 and 2001 I suffered from Hepatitis A, Hepatitis B and several times Pneumonia. Finally a special day came on 01 October 2001 in the early hours of the morning. I received a phone call to say a NEW HEART has arrived. A few long hours later I was lying on the hospital bed with…

a new heart
a new life
a new beginning

My new heart is passionate in helping people to live the best life they can by offering them everything I have to offer… I will run a marathon, fly around the world, spend my nights researching, never sleeping, never resting to do what I have to do to help bring an individual to a healthy lifestyle.

It is the reason I am at university today studying to become the best fitness instructor, the best cardiac rehab specialist, the best dietitian i can be. It is the reason I have started this blog.

This blog will be your ultimate guide to providing you with information and advice about health and fitness or anything related

Bachelor of Sport and Exercise Science (currently in final year)
Certificate III personal trainer
