9 Ketosis Signs In Your Body & Everything About It

9 ketosis signs in your body and everything about it

Ketosis is the phenomena in which our body metabolizes fat instead of carbohydrates to produce ketones, which is further used by our cells to provide the energy to perform their normal functions.

Ketosis is the metabolic state of the body where the blood contains ketones, typically above a range of 0.5mmol/L.

In ketosis, your body metabolizes its fat stores for energy. You enter ketosis when your body doesn’t have enough glucose (carbohydrates) available.

Ketones are byproducts of the body breaking down fat for energy that occurs when carbohydrate intake is low.

While a lot of people follow the ketogenic diet, their purpose is to bring the body into a state of ketosis, which is high fat, adequate protein, and low carb.

Mechanism of Ketosis

1. Cutting the Carbs

When we cut the intake of carbs in our body, the glucose and glycogen levels in our body decrease, which decreases the blood sugar and insulin levels. That is when our body needs other fuel sources and burning of fat comes into the picture.

2. Breaking Down Fats

Ketosis breaks down fats for fuelling energy into the body the process of which is known as beta-oxidation. Here, the body experiences an increase in acetyl-CoA, which turns into acetoacetate.

Acetoacetate then changes to beta-hydroxybutyrate, which is the ketone element that stays in your bloodstream to provide energy to your mind and body.

After a few days into ketosis, the physical performances return to normalcy and in fact with a bang.

A study found that athletes who followed ketosis burned 230% more fat while exercising as compared to athletes who did not follow ketosis [13].
