Weight & Genetic DifferencesOur genetic differences regarding weight are evident at birth. In studies of children by Michael Loewy, Ph.D., those with fat parents have 10 percent lower metabolic rates than do children of non-obese parents, and the rates are 20 percent lower during infancy. But Robert Olsen, M.D., Ph.D., professor emeritus of Medicine at State University of New York, noted that the dissimilarities go far beyond metabolism. "Individuals with strong genetic traits for obesity have a different pattern of fat deposition or mobilization" he says. Multiple researchers have found they convert glucose and other energy sources to body fat more efficiently, their muscles burn fat less readily, their fat cells more readily multiply, and genetic insulin resistance is seen in their skeletal muscles unrelated to their body weight or pancreatic defects. Other physiological differences stacked against the obese, noted by doctors at the University of California at Davis, included hormonal changes and changes at sites in the brain that control satiety - the sense of feeling full - particularly in the hypothalamus.
