It started with an experiment on locusts in 1991. David Raubenheimer and Stephen Simpson, two zoologists who were at the time doing research at Oxford University, wanted to know what would happen to locusts if they varied the relative proportions of protein and carbohydrate in their diets. They therefore conducted an experiment in which they fed locusts pellets containing varying proportions of protein and carbohydrate, … Read more
