There doesn’t seem to be a widely accepted standard method of intermittent fasting but perhaps that doesn’t matter. In the end it is about understanding why you do, the benefits and what suits you.


  • leads to an overall reduction in food for that day.
  • promotes autophagy, the cellular self-cleansing process that breaks down and recycles damaged molecules and cellular organelles leading to a higher percentage of newer, normal cells. By fasting intermittently, autophagy rates can be reset to that of a younger person.
  • speeds up apoptosis, a process that removes older, damaged cells and replaces them with newer and more healthy cells.

One of the most efficient ways of fasting is to miss breakfast, the period of fast is then overnight plus the time until that fast is broken.

If you are relying on carbs for energy your insulin production will demand some food (you will be hungry) making it more difficult to sustain a fast.

If you burn ketones for energy then you will not have an insulin response and not be hungry making fasting easier to sustain.

Autophagy and apoptosis will result in less inflammatory cells and also reduce the risk of malignant cells progressing.

Fasting may increase your life span.
