Does Where You Live Affect What You Weigh

A newly published study from Yale University shows that community-level factors may be associated with reduced adult obesity rates in counties within states that have a high adult obesity rate. Adult obesity rates in the United States have reached epidemic proportions, with one in four people considered obese. Yet, obesity rates vary considerably across states […]

Scientists Identify Two Key Groups of Neurons That Help Regulate Appetite

In a newly published study, Scientists from MIT have identify two key groups of neurons within the hypothalamus that help regulate appetite. MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior. In a study of mice, the researchers found that activating these cells stimulates […]

New Research Reveals How Altered Gut Microbes Cause Obesity

New research from Yale University details how altered gut microbiota causes obesity. Obesity is linked to changes in our gut microbes — the trillions of tiny organisms that inhabit our intestines. But the mechanism has not been clear. In a new study published in Nature, a Yale-led team of researchers has identified how an altered […]

New Link between Obesity and a Common Liver Disease Discovered

The high levels of obesity in the United States contribute to fatty liver disease, the most common form of liver disease. A newly published study from Yale University identifies molecular links between the two, and points to a possible therapy. Fatty liver disease — also known as nonalcoholic steatohepatitis or NASH — frequently progresses to […]

New Studies Shed Light on Critical Dietary Issues Facing Americans

Two newly published studies from the Harvard T.H. Chan School of Public Health shed light on critical dietary issues facing Americans. The first study showed that while recent improvements in the U.S. diet have helped reduce disease and premature death, the overall American diet is still poor. The second study, which analyzed interventions to reduce […]

Researchers Explain the Reason for Genetic Obesity

Researchers from Harvard Medical School and MIT reeval a genetic circuit that controls whether our bodies burn or store fat. Like many other conditions, obesity is caused by an interplay between genetic and environmental factors. While efforts to combat the obesity epidemic will need to include changes in diet and exercise, insights into the genes […]

Researchers Discover a Switch That Controls Metabolism

By analyzing the cellular circuitry underlying the strongest genetic association with obesity, a team of researchers from MIT and Harvard Medical School have unveiled a new pathway that controls human metabolism by prompting our adipocytes, or fat cells, to store fat or burn it away. Obesity is one of the biggest public health challenges of […]

New Discovery Could Help Researchers Increase Good Fat in Patients

A team of researchers has discovered a way to increase energy-burning human brown fat cells and to make them more active, a discovery that could have therapeutic potential for diabetes, obesity, and other metabolic diseases. Harvard Stem Cell Institute (HSCI) scientists have found a way to both make more energy-burning human brown fat cells and […]

Study Shows Energy Drinks Significantly Increase Hyperactivity in Schoolchildren

New research from Yale University shows that middle-school children who consume heavily sweetened energy drinks are 66% more likely to be at risk for hyperactivity and inattention symptoms. The finding has implications for school success and lends support to existing recommendations to limit the amount of sweetened beverages schoolchildren drink. The authors also recommend that […]

Study Shows Weight Training Targets Belly Fat

New research from the Harvard T.H. Chan School of Public Health shows that weight training helps target age-related abdominal fat in men. Healthy men who did 20 minutes of daily weight training had less increase in age-related abdominal fat than men who spent the same amount of time doing aerobic activities, according to a new […]

Study Shows High-Fat Diet Harms Stem Cells in Developing Fetus

A newly published study shows that a diet high in fat during pregnancy harms stem cells in the developing fetus. Physician-scientists at OHSU Doernbecher Children’s Hospital reveal a high-fat diet and obesity during pregnancy compromise the blood-forming, or hematopoietic, stem cell system in the fetal liver responsible for creating and sustaining lifelong blood and immune […]

Researchers Turn White Fat Cells into Brown Fat Cells

Scientists from Harvard have created a system using human stem cells to screen for compounds that have the potential to turn white fat cells into brown fat cells. Harvard Stem Cell Institute (HSCI) researchers have taken what they describe as “the first step toward a pill that can replace the treadmill” for the control of […]

Obesity Costs the USA Billions in Lost Productivity

A new study from Yale University provides state-level estimates of obesity-attributable costs of absenteeism among working adults in the United States, finding that the total national loss in productivity because of obesity-related absenteeism is roughly $8.65 billion per year. Obesity is associated with significant increases in absenteeism among American workers and costs the nation over […]

Researchers Discover a New Signaling Pathway to Combat Excess Body Weight

An international team of researchers has discovered a new signaling molecule capable of activating brown fat cells. The number of overweight persons is greatly increasing worldwide – and as a result is the risk of suffering a heart attack, stroke, diabetes or Alzheimer’s disease. For this reason, many people dream of an efficient method for […]

Researchers Find That Obesity Accelerates Aging of the Liver

A newly published study is the first to evaluate the effect of body weight on the biological ages of a variety of human tissues, revealing that obesity accelerates aging of the liver. Using a recently developed biomarker of aging known as an epigenetic clock, UCLA researchers working closely with a German team of investigators have […]

Researchers Uncover Molecular Process that Transforms White Fat into Brown Fat

Yale scientists uncover how a molecular process in the brain that known to control eating transforms white fat into brown fat, impacting how much energy we burn and how much weight we can lose. The results are published in the October 9 issue of the journal Cell. Obesity is a rising global epidemic. Excess fatty […]

Study Shows Counties With More Dentists Per Capita Have Lower Rates of Obesity

New research from Yale University shows that counties with a higher number of dentists per capita have strikingly lower rates of obesity, finding that counties that had an additional dentist for every 10,000 people had a 1-percentage point lower rate of obesity than the counties without as many dentists. The fight against obesity in the […]
