The quest to answer this double-sided question is in its earliest stages. Already, however, a series of fascinating insights into the biology of obesity has emerged. Behind our broadening behinds and widening waistlines, scientists say, lies a complex array of genes that, directly and indirectly, links our gut to...
Scientists have long suspected that human beings come into the world equipped with dozens, perhaps hundreds, of genes and associated hormones that regulate what scientists call the energy-balance equation. On one side of the equation are the calories we consume. On the other side are the calories we burn...
Intriguingly, some people seem to be more efficient at thermogenesis than others. Researchers led by Dr. Bradford Lowell at Beth Israel Deaconess Medical Center in Boston last month pinpointed three genes that may account for at least some of that variation. Mice that lack the genes, they reported in Science...
Solving the problem is difficult, mostly because of the ferocious debate over how to do it. Biotech partisans say the answer lies in genetically modified crops--foods engineered for vitamins, yield and robust growth. Environmentalists worry that fooling about with genes is a recipe for Frankensteinian disaster. There is no...
