The study also found that [...]
In January, when the Journal of the American Medical Association (JAMA) published a meta-analysis of 100 studies that probed the relationship between body mass index and mortality — studies that found slightly overweight people have lower all-cause mortality than normal weight and underweight people — media around the globe trumpeted the news.
Harvard School of Public Health (HSPH) nutrition experts, including Walter Willett, Frederick John Stare Professor of Nutrition and Epidemiology and chair of the Department of Nutrition, were quoted widely by the media about two obesity studies published in January 2013. The association between sugar and poor health has been contentious over recent decades, with scientists and [...]
Researchers have discovered in fruit flies a key metabolic hormone thought to be the exclusive property of vertebrates. The hormone, leptin, is a nutrient sensor, regulating energy intake and output and ultimately controlling appetite. As such, it is of keen interest to researchers investigating obesity and diabetes on the molecular level. But until now, complex [...]
Sugary cereals, oversized soft drinks, and quarter-pound cheeseburgers are among the unhealthy food choices kids face daily. Junk food, most of it highly processed, and sugar-sweetened beverages are major contributors to the childhood obesity epidemic.
With childhood obesity now affecting 17 percent of American children, the nation is rallying around the concept that serious action is required. Harvard researchers have identified some key triggers for obesity in early childhood.

Synaptic plasticity — the ability of the synaptic connections between the brain’s neurons to change and modify over time — has been shown to be a key to memory formation and the acquisition of new learning behaviors. Now research reveals that the neural circuits controlling hunger and eating behaviors are also controlled by plasticity.
In a first-of-its-kind study, Harvard researchers have shown that cooked meat provides more energy than raw meat, a finding that challenges the current food labeling system and suggests humans are evolutionarily adapted to take advantage of the benefits of cooking.
