The neural and glial bases of diet-induced deficits in control of reward-seeking actions
FY 2023-24
Summary
Attempts to lose weight typically fail over the long term despite strong motivation and determined efforts. We recently found that excess sugar and fat in the diet promotes reliance on habits at the expense of more flexible decision-making based on the value of outcomes produced by behaviour. The aim of this project is to understand how diet-induced obesity impacts brain circuits that control flexible and habitual behaviours which in turn prevent sound eating choices and undermine enduring weight loss efforts. It will help identify novel therapies to restore flexible decision-making, for improved management of diet and weight.

Abstract
Attempts to lose weight typically fail over the long term despite strong motivation and determined efforts. We recently found that excess sugar and fat in the diet promotes reliance on habits at the expense of more flexible decision-making based on the value of outcomes produced by behaviour. The aim of this project is to understand how diet-induced obesity impacts brain circuits that control flexible and habitual behaviours which in turn prevent sound eating choices and undermine enduring weight loss efforts. It will help identify novel therapies to restore flexible decision-making, for improved management of diet and weight.
