A study from the University of Granada reveals that dinner affects sleep quality, which in turn influences breakfast habits. The research tracked obese individuals over 14 days, showing that high-calorie and fatty dinners correlate with poor sleep, while carbohydrate-rich meals promote better rest. Additionally, poor sleep leads to unhealthy breakfast choices. The findings highlight the interconnectedness of diet and sleep, suggesting that changes in one can impact the other, potentially aiding obesity prevention strategies.
