Any plan involving extended fasting or extreme caloric restriction requires supervision by a healthcare provider. Rapid weight loss can lead to gallstones, electrolyte imbalances, and heart strain.

Attempting to lose a large amount of weight through fasting carries significant medical risks and should not be done without professional guidance.

Long periods without food intake can lead to serious deficiencies in essential vitamins and minerals, which can impact every system in the body.

Extreme dieting can sometimes lead to an unhealthy relationship with food. It is important to approach weight loss from a perspective of overall well-being.
