How can it be that we know so little about a thing we do so much? Eating is a vital part of living, yet close to 70% of the population is overweight, indicating that food has become a source of both pleasure and pain. Apparently, most of us are unaware of how what we eat affects us. This series will explore the scientific basis for what has commonly been termed an obesity epidemic, to reveal how we gain weight (it’s not because we eat too much); why the struggle with nagging hunger is not a psychological fault (hunger is a physiological need, so no need for self-blame); and how weight loss and weight control can be achieved (it’s a matter of understanding the glucose/insulin phenomenon). Eating our favorite foods is a wonderful experience. It’s deliciously satisfying, yet for many it leaves an unsettling feeling of remorse, guilt and self-blame, and often results in excess weight. Something terribly and seriously harmful is happening when a human need such as eating is leading to diabetes, hypertension, joint inflammation, depression and pain.
