Fasting for weight loss: Potential health risks and contraindications

When was the last time you ate? Are you still hungry? How long do you have to continue fasting? These are the most frequently asked questions about the diet we're discussing today, and as you’re soon about to see… it may not be worth it.

Intermittent fasting has gained popularity in recent years as a weight loss strategy. It has been touted as an effective and natural way to burn fat and improve overall health. However, it is important to consider both the benefits and potential risks associated with this practice. In this article, we will discuss the negative aspects of fasting for weight loss, as well as its possible contraindications.

Fasting and its impact on metabolism:

When a person fasts, his or her body undergoes a series of metabolic changes. During the fasting period, the blood glucose level decreases, leading to a decrease in insulin production. In response, the body begins to use glucose reserves stored in the liver and muscles for energy. Subsequently, the ketosis phase begins, where the body burns stored fat as a source of energy.

Possible contraindications to fasting:

Despite the potential benefits, fasting for weight loss is not suitable for everyone and may present significant contraindications. Here are some negative aspects to keep in mind:

Pre-existing health problems:

Fasting may be dangerous for people with certain medical conditions, such as diabetes, kidney disease, eating disorders or any other condition that requires regular food intake to maintain a proper balance in the body.

2. Malnutrition and nutritional deficiencies:

Prolonged fasting can lead to insufficient intake of essential nutrients, including vitamins, minerals and protein. This can lead to nutritional deficiencies and long-term health problems if not adequately compensated for.

3. Rebound effect:

Some people may experience a rebound effect after a period of fasting. After resuming normal eating, they may feel hungrier and have more cravings, which can lead to weight gain rather than sustained loss.

4. Problems with intake control:

Intermittent fasting can trigger a disordered eating pattern in some people. Those who have a complicated relationship with food or eating disorders, may be negatively affected by the restrictive approach to fasting.

5. Risk of side effects:

Prolonged fasting can cause side effects such as fatigue, dizziness, constipation and bad breath. These symptoms can be uncomfortable and negatively affect your quality of life.

Before starting an intermittent fasting diet, it is important to be aware of the potential risks and associated contraindications. In addition, it is important to remember that there is no "quick fix" for weight loss, and adopting a balanced approach that includes healthy eating and regular exercise is critical to achieving sustainable results.

Remember, your well-being is the most important thing, and it is essential to adopt healthy habits that are sustainable in the long term.
