Influence of anti-obesity strategies on brain function in health and review: A review.

The aim of this review was to investigate in the literature the application of strategies such as low carbohydrate diet (LCD), ketogenic diet (KD) and intermittent fasting (IF) and their effects on the CNS. We performed a narrative review of the literature. The search was specifically carried out in PubMed, selecting articles in English, which had the following keywords: obesity, central nervous system, low carb diet, ketogenic diet and intermittent fasting, using the narrative review methodology. The studies found show that the benefits of the LCD, KD and IF strategies, at the CNS level, have a strong influence on the mechanisms of hunger and satiety, as well as on the reduction of food reward and show improvement in memory and mood influenced by the interventions.

Therapeutic effects of the gold nanoparticle on obesity-triggered neuroinflammation: a review.

Introduction: Obesity is considered a chronic non-communicable disease characterised by excess body fat. In recent years the prevalence of obesity has grown a lot. Individuals with obesity store the excess of nutrients consumed in the form of fat in adipose tissue, and generate an imbalance of this tissue, where there is the secretion of adipocytokines, which contributes to a peripheral and central inflammatory picture, reaching the central nervous system (CNS), generating neuroinflammation. There is still no effective and safe therapy for the treatment of obesity, many of the drugs marketed has serious side effects. Therefore, there is a search for therapies aimed mainly at reducing inflammation.Objective: In this work the possibility of using a new therapeutic option for obesity will be explored, using nanotechnology. Nanotechnology has gained prominence in recent years for being a promising technology for treatment and as a molecule-in-the-light in inflammatory diseases. Gold nanoparticles (GNP) stand out among nanomaterials because they demonstrate anti-inflammatory characteristics by various pathways, and have been widely used in the treatment of inflammatory diseases, including in the CNS, demonstrating excellent results.Result: Thus, the use of GNP for the treatment of obesity is promising due to the inflammatory state of obesity, thus acting as anti-inflammatory at the peripheral and central levels.
