As Dr. Attia says: “if you want to actually understand this topic, you must invest the time and mental energy to do so.  You really have to get into the details.” For those of you who want to know the science behind nutritional ketosis (NK), this blog is for you!

This blog by  Hrefna Palsdottir, MS at authoritynutrition.com, explains what ketosis is and why it’s our natural metabolic site. She explains how it is a metabolic state in which fat provides most of the fuel for the body.

One study reported 2.2 times more weight loss for people on a ketogenic diet, compared to those on a low-fat, calorie-restricted diet.

What’s more, people tend to feel less hungry and more full on a ketogenic diet, which is attributed to ketosis. For this reason, it is generally not necessary to count calories on this diet.
