Fasting is a common practice, particularly in India, followed by people to detox their bodies. However, fasting for two or more days in a row can impact our overall health. Tap to know what happens when we fast for two days consecutively.

Improves Insulin Sensitivity

Fasting improves insulin sensitivity as the blood sugar drops, which can help reduce the risk of type-2 diabetes and improve blood sugar control.

Slows Down Metabolism

Frequent or consecutive fasting can slow down the metabolism, which can reduce calorie burning, making it difficult to lose weight.

Reduces Inflammation

Consecutive fasting for two days can also reduce inflammation in the body, lowering the risk of heart diseases, arthritis, and other diseases.

Muscle Loss

Fasting can also lead to muscle loss, as the body starts breaking down the tissues for energy, reducing the lean muscle mass.

Mental Clarity And Focus

It also boosts mental clarity and focus as the ketones produced during fasting help improve brain function, which also boosts mood.

Electrolyte Imbalance

Two days of fasting can also lead to electrolyte imbalance, as we lose electrolytes like sodium, potassium, and others through urine, causing weakness or cramps.

Increased Hunger

People who are fasting may experience hunger and dizziness, as the body is used to regular meal times, and low blood sugar can also increase appetite.
