Extreme diets for fat loss often promise easy and rapid weight loss; however, most have not been proven effective and may even pose health risks. Some people seek short-term results and expose themselves to serious eating disorders such as anorexia nervosa. If necessary, qualified professionals are the ones who can ensure adherence to a diet with healthy changes in eating habits and lifestyle.

One of the main risks of these types of diets stems from the excessively rapid weight loss. Drastically reducing calorie intake leads to nutritional imbalances.

Any diet that prohibits or suggests unlimited consumption of any food is not a healthy option. In most cases, because they are not designed by qualified professionals, they are not tailored to the individual's needs and characteristics and may be contraindicated if other health conditions exist or if the person is taking medication.

Going on an extreme diet, under the promise of being a diet to lose weight in 1 week, is a risk factor for suffering from an eating disorder, such as anorexia or bulimia nervosa.

People with a self-demanding and perfectionistic nature can become obsessed and drastically reduce their food intake, even to the point of malnutrition. Hunger and weight loss can alter brain function in vulnerable individuals, potentially perpetuating restrictive eating behaviors and hindering a return to normal eating habits.

How do young people feel about their bodies?

Extreme diets can cause irritability, insomnia, headaches, muscle loss, hair loss, and recurring coldness in the hands and feet as the body lowers its temperature to conserve the limited energy available. The characteristic psychological effects include the onset of depressive symptoms.

If you think you need to lose weight or modify your diet to make it healthier, we recommend that you consult a healthcare professional who can assess your case and advise you in a personalized way.
