• Abstract:

  This study focuses on the critical analysis of new and popular dietary and pharmacological trends: the carnivorous diet, intermittent fasting and the use of new GLP-1/GIP receptor agonists, such as tirzepatida (the active ingredient in Mounjaro, often associated in public perception with drugs such as Ozempic). The aim is to investigate and expose the harms, risks and scientific limitations associated with these practices, contrasting them with the benefits widely publicized in the public sphere. The study methodology consisted of a Bibliographic Review carried out from February to June 2025, using the PubMed database. Five studies were selected that met the inclusion criteria: articles in Portuguese, English, Spanish and French, published between 2015 and 2025. The results show that the carnivore diet, despite its popularity, is based on anecdotal evidence and poses significant risks to cardiovascular and nutritional health, such as increased LDL cholesterol and lack of fiber. Intermittent fasting shows modest efficacy in weight loss, no better than continuous calorie restriction, while imposing risks such as hypoglycemia and side effects that compromise adherence. Tirzepatide, on the other hand, shows revolutionary efficacy in weight reduction, but at the cost of a high incidence of gastrointestinal adverse events and an increased risk of serious conditions such as pancreatitis and cholecystitis, with its long-term cardiovascular safety still to be established. It is concluded that, although attractive, these trends carry a significant burden of harm that defies the narrative of simple and safe solutions. The adoption of these practices can expose individuals to adverse health consequences, making a more critical and informed approach by health professionals and the public essential.
