Oxygen is used to convert food into energy. By improving your oxygen efficiency we improve the way you metabolise food.

Here is a brief explanation of Metabolism.

Metabolism.
The term for the way cells chemically change food so that it can be used to keep the body alive. It is a two-part process. One part is called catabolism-when the body uses food for energy. The other is called anabolism-when the body uses food to build or mend cells.

70% metabolism is concerned with just keeping us alive (Groff, 1999), termed Resting Metabolic Rate (RMR). It is a huge part of total metabolism, so improving resting metabolic rate will have a big impact on overall weight loss.

The main food source used by all our estimated 6 trillion cells is ATP ( adenosine triphosphate). Your metabolism converts food into ATP with the use of Oxygen. The greatest energy reserve is fat, before carbohydrate. As the body carries out aerobic respiration, foods are broken down in the presence of oxygen to produce ATP. When the body is working efficiently it will use fat (as well as glycogen), being the most abundant food source to produce ATP. When it needs are greater it will choose to break down easier substances like carbohydrates, these supplies are more limited. Finally, when the demand can not be met aerobically, the body adapts to anaerobic respiration, by which glucose is broken down to lactic acid and ATP is formed.

The way an individuals metabolism works can determine their predisposition to put on, or loss weight.

People who do not seem to gain weight burn fat and carbohydrates for energy in the expected manner while at rest.

Overweight people tend to burn greater quantities of carbohydrates, and thus store fat. The body has a limited supply of carbohydrates; “Carbohydrate burners” often crave food rich in this food source i.e sugar and starch. No more than 20% of your total daily calories should come from fat

Underweight people can afford to eat more fat than normal as this is the preferred food source used to produce energy. “Fat burners” may increase the amount of fat they eat to approximately 30% of total daily calories, if desired. However, for health reasons, you should still limit the amount of saturated fat you eat.
