Seth Roberts - a psychology professor at the University of California, Berkeley - experimented with a whole range of diets before arriving at one which not only worked extraordinarily well, but took the least amount of effort and willpower, and worked without deprivation. Based on the principle that you have a weight set-point, which you eat to until you no longer feel hungry, Seth recommends that you have a regular tablespoonful of light olive oil or sugared water between meals to lower your set-point, lower your hunger - and therefore lower your weight. No calorie counting, no change of diet - and no hunger. It's that simple!
