          Abstract

          RESUMEN La obesidad es el trastorno metabólico más frecuente, para el tratamiento es fundamental el cambio del tipo alimentación y mantener un estilo de vida saludable. La publicidad engañosa sobre productos denominados milagrosos conlleva a un consumo desmedido, no controlado y sin previa evaluación de los resultados sobre el peso y/o la posible toxicidad de los mismos. Se diseñó una investigación preliminar en ratones, para verificar el efecto del zumo de Aloe barbadensis y un producto comercial sobre el peso de ratones normopesos y obesos inducidos por glutamato monosódico (GMS), después de cuatro semanas de tratamiento. El grupo de ratones inducidos a obesidad con GMS, presentaron un porcentaje de cambio de peso de 160,5±37,5%, mientras que en el grupo de ratones normopesos fue de 59,4±12,1%, esta diferencia resultó significativa (p<0,001). En los ratones obesos que recibieron el zumo de A.barbadensis se logró un descenso no significativo de peso de 2,8% con respecto al peso al inicio de la intervención (p (0,05). En los ratones obesos tratados con el producto comercial se observó un aumento de peso, aunque en menor proporción que los obesos que recibieron agua (3,5% y 4,4%, respectivamente). Los resultados indican que el zumo de Aloe barbadensis induce un descenso de peso mayor en los animales obesos, comparado con el producto comercial, sin embargo, esto no es significativo en el periodo de observación.

          ABSTRACT Obesity is the most frequent metabolic disorder, for the treatment is fundamental to change the type of food and maintain a healthy lifestyle. Misleading advertising of so-called miraculous products leads to excessive, uncontrolled consumption and without prior evaluation of the effect on weight or their possible toxicity. A preliminary investigation was designed in mice, to verify the effect of the juice of Aloe barbadensis and a commercial product on the weight of normal and obese mice induced by monosodium glutamate(MSG),after four weeks of treatment. The group of mice induced to obesity with MSGhad a weight change percentage of 160.5 ± 37.5%, while in the group with normal body weight was of 59.4 ± 12.1%, this difference was significant (p<0,001). In the obese mice that received the juice of A. barbadensis, a non-significant weight decrease of 2.8% was achieved when compared with the weight at the beginning of the intervention (p(0.05). In obese mice treated with the commercial product,an increase in weight was observed, although in a smaller proportion than the obese ones that received water (3.5% and 4.4%, respectively). The results indicated that Aloe barbadensis juice induced a greater weight loss in obese animals, compared to the commercial product, however, this is not significant in the period considered.

          Screening for and management of obesity in adults: U.S. Preventive Services Task Force recommendation statement.

          Update of the 2003 U.S. Preventive Services Task Force (USPSTF) recommendation statement on screening for obesity and overweight in adults. The USPSTF reviewed new evidence on the benefits and harms of screening and primary care–feasible or referable nonsurgical weight-loss interventions. The USPSTF recommends screening all adults for obesity. Clinicians should offer or refer patients with a body mass index of 30 kg/m(2) or higher to intensive, multicomponent behavioral interventions (B recommendation).

              Oral ingestion of aloe vera phytosterols alters hepatic gene expression profiles and ameliorates obesity-associated metabolic disorders in zucker diabetic fatty rats.

              We investigated the effects of the oral administration of lophenol (Lo) and cycloartanol (Cy), two kinds of antidiabetic phytosterol isolated from Aloe vera , on glucose and lipid metabolism in Zucker diabetic fatty (ZDF) rats. We demonstrated that the administrations of Lo and Cy suppressed random and fasting glucose levels and reduced visceral fat weights significantly. It was also observed that treatments with Lo and Cy decreased serum and hepatic lipid concentrations (triglyceride, nonesterified fatty acid, and total cholesterol). Additionally, Lo and Cy treatments resulted in a tendency for reduction in serum monocyte chemotactic protein-1 (MCP-1) level and an elevation in serum adiponectin level. Furthermore, the expression levels of hepatic genes encoding gluconeogenic enzymes (G6 Pase, PEPCK), lipogenic enzymes (ACC, FAS), and SREBP-1 were decreased significantly by the administrations of aloe sterols. In contrast, Lo and Cy administration increased mRNA levels of glycolysis enzyme (GK) in the liver. It was also observed that the hepatic β-oxidation enzymes (ACO, CPT1) and PPARα expressions tended to increase in the livers of the Lo- and Cy-treated rats compared with those in ZDF-control rats. We therefore conclude that orally ingested aloe sterols altered the expressions of genes related to glucose and lipid metabolism, and ameliorated obesity-associated metabolic disorders in ZDF rats. These findings suggest that aloe sterols could be beneficial in preventing and improving metabolic disorders with obesity and diabetes in rats.
