Abstract
Worldwide obesity has tripled since 1975, with 1.9 billion adults considered overweight. The condition now kills more people across the globe than underweight and malnutrition.
One of the NHS’s biggest cost burdens, a staggering 70% of UK adults are expected to have overweight or obesity by 2034. Obesity is a problem of energy balance. If a person has more calories coming in than are going out, then the difference is generally stored as body fat. But what needs to be identified are the factors causing the imbalance of intake and spending in the first place. Why don’t humans have a control system that allows them to eat exactly what they need and no more? Understanding the answer to this question may help tackle the obesity epidemic.
