To fully grasp the Living Lean philosophy you must comprehend and fully understand the pH scale.
 
pH is a term that measures acidity or alkalinity of water soluble substances (pH stands for ‘potential of Hydrogen’).
 
A pH value is represented on a scale that runs from 1 to 14, with 7 as the middle (neutral) point. The human body however has a neutral pH of 7.365.
 
Values below 7 indicate acidity. Acidity levels increase as the number decreases with 1 being the most acidic.
 
Values above 7 indicate alkalinity. Alkalinity levels increase as the number increases with 14 being the most alkaline.
 
This scale, however, is not a linear scale like a centimetre or inch scale (in which two adjacent values have the same difference). It is a logarithmic scale in which two adjacent values increase or decrease by a factor of 10. For example, a pH of 3 is ten times more acidic than a pH of 4, and one hundred times more acidic than a pH of 5. Similarly, a pH of 9 is ten times more alkaline than a pH of 8, and one hundred times more alkaline than a pH of 7.

The pH scale plays a very important role in achieving results on the Living Lean program. To ensure success you will be required to keep your body’s pH level above 7.365.
 
Why?
 
Doing this ensures that the body is in an alkaline state and not an acidic one (we will discuss this further and in more detail in the next chapter).
 
Testing your pH is as simple as visiting the bathroom. Urinating on litmus paper on your first visit to the bathroom each day will provide an accurate reading of your pH level.
 
When conducting the test the litmus paper will change colour. Compare the colour of the wet paper to the scale found in the packaging. This will give you an accurate reading of your pH level.
 
The Living Lean program requires you to check your pH on a daily basis. This will provide continual feedback on whether you are in a healthy, fat burning (alkaline) state or an unhealthy fat storing (acidic) state.
