Resecting a majority of the small intestine—a popular weight-loss surgery half a century ago—led to severe malnutrition and eventual death.

Obesity triggers a fatty acid synthesis pathway, which in turn helps drive T cell differentiation and inflammation.

Adipogenesis in mice has alternating genetic requirements throughout the animals’ lives.

The accumulation of fat within skeletal muscle, as happens with obesity, diminishes muscle performance.

Weight-loss drugs that target newly characterized obesity-related receptors and pathways could finally offer truly effective fat control.

New research on how fat influences brain neuronal activity

Obesity appears linked to the gut microbiome. How and why is still a mystery—but scientists have plenty of ideas.

Overeating and inactivity lead to insulin resistance in just days—and oxidative stress is to blame.

Why do some obese people actually experience health benefits?

Bruce Spiegelman has spent his career at the forefront of adipocyte differentiation and metabolism.

Science is approaching a better understanding of the increasingly prevalent disease; the consequences of succeeding in this quest are great.

Science tells us obesity is a chronic disease. Why does the outmoded and injurious notion that it is a problem of willpower persist?

Meet some of the people featured in the November 2015 issue of The Scientist.

The causes and consequences of obesity are more complicated than we thought.
