Cutting key amino acids from mouse diets triggers weight loss through heat burning

It's not pleasant to shiver from the cold, but for some, it has the appeal of making the body burn more energy as heat than when staying in a warmer environment. According to several studies, exposure to cold is a reliable way to boost energy expenditure in mice and humans. This process of burning energy through heat loss is called thermogenesis.

Novel way to 'rev up' brown fat burns calories, limits obesity in mice

Researchers at Washington University School of Medicine in St. Louis have identified a novel way brown fat—an energy-burning form of fat—can rev the body's metabolic engine, consuming cellular fuel and producing heat in a way that improves metabolic health. The study, in mice, reveals new avenues to exploit brown fat to treat metabolic diseases, such as insulin resistance and obesity.

Marsupials key to discovering the origin of heater organs in mammals

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research from Stockholm University shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The work is published in the journal Science.

Mouse Experiment Uncovers a Crucial Switch That Breaks Down Fat For Warmth

Scientists have located the body's toggle for breaking down brown fat – a type of adipose tissue that burns calories to generate warmth.

UCLA Discovers Weight Loss Game-Changer: Stimulating Brown Fat To Fight Obesity

A UCLA-led team of researchers has found nerve pathways that supply brown adipose tissue (BAT), a type of tissue that releases chemical energy from fat metabolism as heat – a finding that could pave the way toward using it to treat obesity and related metabolic conditions. The researchers have fo
