Breakfast Consumption and Cardiometabolic Health
Summary
Breakfast habits have long been implicated in energy balance, weight regulation and long-term cardiometabolic outcomes. Regular morning feeding appears to influence daily energy intake, patterns of physical activity and post-prandial blood glucose stability. Observational cohorts link habitual breakfast skipping with higher body mass index, adverse lipid profiles, elevated blood pressure and increased risk of type 2 diabetes. Intervention studies suggest that consuming a substantial morning meal boosts physical activity thermogenesis without altering resting metabolic rate, while extended fasting until midday may provoke larger lunch intakes and greater glycaemic variability later in the day. Across age groups and settings, breakfast quality—characterised by whole grains, fruit and dairy—correlates with overall dietary adequacy and more favourable cardiometabolic markers. Nonetheless, methodological heterogeneity in defining breakfast and measuring long-term health outcomes leaves important gaps in causal understanding.

Breakfast Consumption and Cardiometabolic Health publication trend
The graph below shows the total number of articles in breakfast consumption and cardiometabolic health across all publications each year (not limited to Nature Index journals).
Technical terms
Cardiometabolic health: The combined state of cardiovascular and metabolic risk factors, including blood pressure, lipid levels and glucose regulation.
Physical activity thermogenesis: Energy expenditure attributable to movement and exercise beyond resting metabolic needs.
Resting metabolic rate: The rate of energy consumption by the body at rest to sustain basic physiological functions.
Glycaemic variability: Fluctuations in blood glucose concentrations over time, reflecting metabolic stability.
Insulin resistance: A diminished cellular response to insulin signalling, often preceding type 2 diabetes.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
