TL;DR: Obesity and depression form a pathophysiological trap: inflammatory cytokines and dysbiotic bacteria from obesity trigger neuroinflammation and mood disruption, while depression’s behavioral changes and HPA axis dysfunction worsen obesity. Obesity and depression are twin epidemics in the modern world, and they’re not independent. People with obesity are 1.5 to 2 times more likely to …
A new study examined whether metabolic biomarkers assessed through a high-throughput method are associated with future depressive symptoms. The results suggest the metabolites may not play a direct role in depression development. Key Facts: Researchers investigated associations between 121 metabolic measures and depressive symptoms at 7-year follow-up. Some metabolites showed tendencies for links with more …
Medications are meant to treat medical conditions and improve health, but some can have the unintended consequence of weight gain, which can then worsen other health risks. Understanding which medications tend to cause weight gain and the mechanisms behind this effect can help patients and doctors make informed treatment decisions. Key Facts: Medications for diabetes, …
Semaglutide is emerging as a wonder drug for management of various metabolic diseases. Originally approved for type 2 diabetes, this glucagon like peptide-1 (GLP-1) receptor agonist is now showing promise for treating obesity, non-alcoholic steatohepatitis (NASH), and neurodegenerative diseases like Alzheimer’s and Parkinson’s. Let’s explore the therapeutic potential of semaglutide and how it acts as …
Eating large amounts of ultra-processed foods may increase the risk of obesity, heart disease, stroke, depression, and early death, according to a new systematic review and meta-analysis. Key Facts: Ultra-processed foods are industrial formulations made with ingredients extracted from foods or synthesized in labs. Examples include chips, soft drinks, instant noodles, chicken nuggets, and frozen …
A new randomized, double-blind, placebo-controlled clinical trial provides evidence that a green coffee bean extract standardized to chlorogenic acids (CGA-7) can help with weight loss in healthy overweight adults. Key facts: CGA-7 supplementation for 12 weeks resulted in significant reductions in body weight, BMI, body fat percentage and fat mass compared to placebo. Improvements were …
A new case-control study reveals an association between obesity, depression, and decreased levels of the protein neuregulin-1 (NRG-1). The research suggests NRG-1 may serve as a biomarker linking depression and obesity. Key facts: Depressive symptoms were more common in obese individuals compared to normal weight controls. After bariatric surgery, most obese patients saw an improvement …
Obesity can lead to impaired learning, memory and cognitive decline, but the underlying mechanisms are not fully understood. A new mouse study reveals how obesity disrupts key signaling pathways in the brain, and shows the potential of two diabetes drugs, semaglutide and empagliflozin, to counteract these effects. Key Findings: Obesity impaired spatial learning and memory …
A new systematic review and meta-analysis suggests that swapping out sugar-sweetened beverages (SSBs) for low- and no-calorie sweetened beverages (LNCSBs) may support modest weight loss and improve certain cardiometabolic factors. The study found that LNCSBs offer similar benefits to water, the standard substitution recommended by health authorities. Key findings: Replacing SSBs with LNCSBs was linked …
A new study looked at how having diabetes may impact brain health in Native Americans. The researchers found that the longer someone had diabetes, the more it affected their brain. But other health issues like obesity did not appear to impact the brain as much. Key facts: The study involved 51 Native Americans with type …
