There is a new study published on Dec.26 from the New England Journal of Medicine that intermittent fasting is a legitimate option to consider.

“The state of the science on intermittent fasting has evolved to the point that it now can be considered as one approach with exercise and healthy food to improving and maintaining health as a lifestyle approach,” stated by Mark Mattson, a neuroscientist with Johns Hopkins Medicine in Baltimore.

Two main routes to adopt intermittent fasting into our life, Mattson said:

When bodies are fasting, they are gradually burning through the glucose stored in their liver, Mattson told.

The liver contains about 700 calories of glucose.

“It gets 10 to 12 hours to use the liver’s energy stores, Then what happens is, fats are used for energy,” Mattson said.

This process is described “metabolic switching,” and the three-meals-a-day eating pattern favoured by Americans doesn’t allow their bodies to run through their liver’s energy stores and make the switch to fat burning, Mattson said.

Mattson including colleagues compiled the current scientific evidence. Studies show that intermittent fasting can:
