Your biology’s been hacked.

Your naturally evolved appetite would allow you to eat exactly the right amount of food every day, except that most of us live in highly industrialised food environments today.

Two of nutrition’s most productive scientists explain how we ended up here, and how you can eat healthier in an imbalanced food environment.

Why don’t animals need calorie trackers?

Baboons don’t know the difference between fats and carbs, don’t follow a keto diet and don’t track what they eat. Yet we humans, who have all this technology at hand, are facing an obesity epidemic when no other animal seems to struggle with healthy eating. How is that possible?

Professors Steve Simpson and David Raubenheimer have strived to answer that question for as long as they’ve worked together. By studying the feeding patterns of locusts and paying extra attention to protein, they’ve concluded that humans should be able to eat as well as the animals – but our modern food environment won’t let us.

Steve is Academic Director of the Charles Perkins Centre, and a Professor in the School of Life and Environmental Sciences at the University of Sydney, and Executive Director of Obesity Australia. David is the Leonard P Ullmann Chair in Nutritional Ecology at the University of Sydney.
