Fasting consists of abstaining from food for a specific period of time, which can vary from a few hours to several days, practiced for religious, health and weight loss reasons. Intermittent fasting, which alternates between periods of eating and fasting, has been shown to have positive effects on metabolic health and longevity. Dr. María José Seminario, a specialist in general medicine at the Plaza Lima Sur Medical Center of the Ricardo Palma Clinic, provides us with valuable information on this practice.

Can everyone fast?

While fasting can be beneficial for many people, it is not suitable for everyone. People with certain medical conditions, such as diabetes, eating disorders or pregnant women, should refrain from fasting without proper supervision by a health professional.

What recommendations should be taken into account when fasting?

It is extremely important that people who choose to fast adopt a safe and responsible approach. Our specialist recommends following these guidelines:

• Staying hydrated is essential during fasting. Drinking water and other non-caloric beverages, such as tea or coffee, can help prevent dehydration.
• Balanced diet. It is important to consume nutritious and balanced meals before and after fasting to ensure that the body receives the necessary nutrients.
• Listen to your body. Pay attention to your body’s signals during fasting. If you experience dizziness, weakness or discomfort, stop fasting immediately and seek medical attention if necessary.

What are the consequences if a person does not fast properly?

Poorly performed fasting can have negative health consequences. Dehydration, hypoglycemia (low blood sugar levels) and loss of muscle mass are potential risks if fasting is not practiced properly. In addition, prolonged or extreme fasting can lead to nutritional deficiencies and eating disorders.

Remember:

Fasting can be an effective tool for improving health in certain circumstances, but it is essential to practice it safely and under proper supervision. Seek the guidance of a health professional before starting any fasting regimen.
