Increased Energy
Starting on a ketogenic diet may result in fatigue and feeling sick. In the first few days or a week of changing food intake, people who switch on the diet may experience what is coined as the general term keto flu. However, as the body gets used to the changes and reaches full ketosis, the keto flu usually clears up, and a feeling of renewed energy sets in.
Experts explain this as a normal course of the transition process. When one switches to a high-fat and low-carb diet, their body needs time to adapt to burning more fat instead of carbs for fuel. Then, as they get into ketosis, things start to work correctly, allowing them to enjoy increased energy.
Ketones are a highly potent source of fuel for the brain. Therefore, when its level in the bloodstream elevates due to ketosis due to a ketogenic diet, it helps improve brain function as well. Another cause for increased energy during ketosis is low carb intake. Fewer carbohydrates equate to a more stable sugar level, which furthers the energy-boosting benefit of the diet change.
