Famous Randolph M. Nesse Quotes

“Treatment of eating disorders is improved by the recognition that strenuous dieting arouses famine protection mechanisms that are prone to initiate a positive feedback spiral.”

“Eating disorders were not shaped by selection, but mechanisms that regulate eating during famines were. ADHD was not shaped by selection, but mechanisms that regulate attention were. Serious depression was not shaped by natural selection, but capacities for normal low and high mood were.”

“Patients with anorexia nervosa and bulimia nervosa are surrounded by excess food, but their bodies are aware only of starvation. Their behavior is appropriate for a situation in which getting just a few extra calories might make the difference between life and death.”

“The starting point is recognizing that selection has shaped powerful mechanisms to protect against starvation. During a famine, those mechanisms motivate animals to get food -any food- eat it quickly, and eat more than usual, because food supplies are obviously erratic. The system also adjusts the body weight set point upward because extra fat stores are valuable when food sources are unreliable. And, as noted already, weight loss slows down metabolism, which is appropriate when a person is starving but the opposite of what is needed when trying to lose weight. Also, intermittent access to food signals unreliable access to food supplies, so it increases food intake and bingeing, even in rats.”
