Intermittent fasting refers to eating plans that alternate between fasting and eating

periods.

The goal is to systematically starve the body long enough to trigger fat burning.

While research is still underway and the method may not be suitable for everyone, there is

evidence that, when done correctly, intermittent fasting can help lose weight, lower blood

pressure and cholesterol, prevent or control diabetes, and improve brain’s health.

During a meal, carbohydrates in food are broken down into glucose.

Glucose absorbs through the intestinal wall into the bloodstream and is transported to

various organs, where it serves as the major energy source.

Excess glucose is stored for later use in the liver and adipose tissue, in the form

of glycogen and fats.

In between meals, when the body is in the fasted state, the liver converts glycogen

back to glucose to keep supplying the body with energy.

Typically, an inactive person takes about 10 to 12 hours to use up the glycogen stores,

although someone who exercises may do so in much less time.

Once the reserve of glycogen in the liver is depleted, the body taps into energy stores

in adipose tissues.

This is when fats are broken down into free fatty acids which are then converted into

additional metabolic fuel in the liver.

Thus, if the fasted state lasts long enough, the body burns fat for energy and loses that

extra fat.
