Healthy Weight Research Themes
Priority Research Themes
Our work is carried out across four workstreams. Click below to explore the research projects we are conducting under each of these themes.

Lifecourse prevention & weight management workstream
The Lifecourse Prevention and Weight Management workstream assesses policy settings across the life-course with a particular focus on schools, families and neighbourhoods.

Behavioural science workstream
The Behavioural Science workstream establishes the environmental, social, psychological and behavioural processes contributing to weight trajectories and mental health, identifying how behaviour change and modifications to the micro- and macro-environment can be harnessed to support healthy weight.

Economic circumstances and outcomes workstream
The Economic Circumstances and Outcomes workstream undertakes analyses to understand dietary choices and how policy can affect these choices; it will analyse responses and resilience to economic shocks, and how effects interact with existing inequalities.

Food systems and policy analysis workstream
The Food Systems and Policy Analysis workstream undertakes methodological innovations in qualitative and mixed methods to evaluate the impact of policy approaches on people experiencing inequalities and food systems affected by policy.
