Researchers have conducted a study focusing on specific brain cells called GABRA5 neurons in the lateral hypothalamic area (LHA) of male rats to understand their role in managing obesity.  These neurons have connections to both white and brown fat tissues in the body.  When obese mice had their GABRA5 neurons suppressed, they experienced metabolic impairments and weight gain, whereas reducing the activity of an enzyme called MAO-B in nearby astrocytes led to increased fat burning and less weight gain.  This suggests that these neurons may help prevent fat accumulation, offering potential insights into obesity treatment strategies.  Additionally, brown adipose tissue (BAT) has been associated with lower risks of cardiometabolic diseases, and a drug called KDS2010, which inhibits MAO-B, has shown promise in promoting weight loss and is in Phase 1 clinical trials as a potential obesity treatment.  Read Original Article

  Breakthrough Obesity Drugs. Could dieting become obsolete? Carlos Martinez Sagasta In the past 50 years, the prevalence of obesity has tripled. Being significantly overweight increases the chances of developing various health issues like type 2 diabetes, heart disease, and several malignancies. The need for the creation of efficient obesity treatments is growing as obesity rates rise. New hormone-mimicking pharmaceuticals may reduce hunger and encourage weight loss regarding the advancement and possibility of novel treatments for obesity. It may reduce the cause of experiencing emotions of guilt and the stigma associated with being overweight. GLP-1 receptor agonists, which have been biochemically designed to increase potency and have a sustained effect, are successfully used in clinical settings to treat type-2 diabetes. The GLP-1 analogue Semaglutide was initially licensed by the US FDA to treat type 2 diabetes, but was later approved as a medication to treat obesity. In a...

Inhaling Pleasant Scents During Sleep Tied to a Dramatic Boost in Cognition In a small, randomized control trial researchers found that when cognitively normal individuals were exposed to the scent of an essential oil for 2 hours every night over 6 months, they experienced a 226% improvement in memory compared with a control group who received only a trace amount of the diffused scent. Ozempic is in the spotlight but it's just the latest in a long and ... Patients on an endless cycle of dieting and exercise want something more convenient, with a more certain outcome. And doctors, too, want to offer patients effective treatment, and a drug prescription is a workable option given the constraints of appointment times. 5 Ways Jaclyn Smith Loses Weight at 77 "What we put on our bodies shows up on our faces," she told Fox and one way she ensures she gets the nutrients needed is by having a green smoothie every day.
