Late breakfast linked to higher health risks

Older adults who eat breakfast late face higher mortality and health complications

Key points from article :

Researchers from Mass General Brigham have found that older adults who eat meals later in the day, particularly breakfast, may face higher risks of health problems and premature death. The study tracked 2,945 adults aged 42 to 94 over two decades, examining meal timing, lifestyle factors, blood samples, and health outcomes. They observed that as people age, both breakfast and dinner tend to shift later, while the overall eating window narrows. Importantly, delaying breakfast was associated with an increased risk of mortality.

Nutrition scientist Hassan Dashti, a co-author of the study, emphasized that regular and consistent meal timing could support better health and aging. He noted that later meal times may signal underlying physical or mental health issues, including fatigue or depression. Genetics and lifestyle factors also play a role: individuals who are naturally “night owls” or have poor sleep patterns are more likely to eat later.

The findings have practical implications for daily habits. Registered dietician Dr. Rimas Geige suggests that older adults may benefit from light but nutrient-rich breakfasts, such as toast with almond butter and a banana, providing steady energy without being overwhelming. This approach aligns with the idea that breakfast remains a critical meal for maintaining health in aging populations.

While intermittent fasting and time-restricted eating have gained popularity, the researchers caution that delaying meals unintentionally may not be beneficial for older adults. Dashti highlighted that although intermittent fasting can have benefits, later meal times—especially a late breakfast—could pose risks, underscoring the importance of aligning eating patterns with the body’s needs in later life.
