A New Diet Equation - The Science of Appetite - TIME

For effective weight loss, you may need to pick a diet that works for your body type. Apple-shaped people seem faster at secreting insulin compared to pear-shaped people.

For pear-shaped people, both types of diets seem to lead to similar levels of success.
