## Sleep affects diet
Poor sleep links to unhealthy eating habits for both partners in a study of 204 cohabiting couples.

> People with a sleep-deprived partner were essentially saying they have less confidence in their ability to follow a healthy diet, so they engage in less effort to do so.
## Shared sleep issues
One partner's poor sleep hygiene disrupts both partners' sleep quality and eating routines.
## Diet changes happen
Women reported healthier eating habits after the study, while both partners tried to improve their diets.
## Study limitations
Self-reported data means the study can't prove poor sleep directly causes unhealthy eating habits.
## Joint solutions
Both partners need to work together to improve sleep and food habits for long-term health.
## Key takeaway

Poor sleep in one partner reduces both partners' efforts to eat healthily.
