- A study using Australian population data found little change in diet or body weight when people moved into retirement.
- Physical activity increased modestly, mostly replacing work related activity, and longer retirement was linked to a small reduction in obesity among men.
- The authors argue healthier habits need to be supported well before retirement through workplace wellbeing and community programmes.
Retirement is often seen as a fresh start, with more time to cook, walk and focus on health.
This analysis suggests that, for many people, those changes do not happen automatically.
Researchers used data from a large Australian study that tracks households over time.
They examined how diet, physical activity and weight changed as people moved into retirement and as retirement continued.
Overall, they found no clear evidence that retirement itself led to meaningful changes in body weight for men or women.
Diet also showed few shifts, suggesting people generally keep eating patterns they already have.
Physical activity did rise, but the increase tended to replace work related movement with similar levels of exercise rather than creating a major boost in total activity.
One nuance was that longer time in retirement was linked to a modest reduction in obesity among men, while women did not show the same pattern.

For diabetes prevention and type 2 diabetes management, the implication is straightforward: do not wait for a life stage change to improve habits.
If anything, the best time to build routines is before retirement, while structures and support can be put in place.
The authors point to workplace wellbeing programmes before retirement and community based options after retirement, such as group activity, social exercise and age friendly infrastructure.
