Regularly skipping breakfast may be associated with an increased likelihood of developing high blood pressure, according to research examining the eating habits and cardiovascular health of more than 14,000 adults. The findings suggest that when people eat their first meal could play a role in blood pressure regulation, although scientists have not established that missing breakfast directly causes hypertension.
The association has received renewed attention following an October 2026 report by Health examining the potential cardiovascular consequences of routinely missing the morning meal. Researchers have identified several possible explanations, including changes in stress hormones, metabolic regulation, dietary quality and body weight, but the evidence remains insufficient to determine whether eating breakfast itself prevents high blood pressure.
The principal findings come from a 2022 systematic review and meta-analysis of six observational studies involving 14,189 adults, including 3,577 participants who regularly skipped breakfast. Researchers found that habitual breakfast skippers had approximately 20% higher odds of hypertension than people who consistently ate a morning meal, even after accounting for several factors that could influence cardiovascular risk.
The study, published in the International Journal of Hypertension, examined research conducted in the United States, South Korea and Ghana between 2011 and 2021. The included studies involved community-dwelling adults, employees and patients with Type 2 diabetes, allowing investigators to assess whether the association appeared across different populations and health circumstances.
After combining the results, researchers calculated an adjusted odds ratio of 1.20 for hypertension among breakfast skippers, with a 95% confidence interval ranging from 1.08 to 1.33. The findings were statistically significant, and the relationship remained generally consistent when individual studies were excluded from the analysis or researchers examined different population groups.
An odds ratio of 1.20 represents a 20% increase in the odds of hypertension, not necessarily a 20% increase in an individual’s absolute risk. The distinction matters because the likelihood of developing high blood pressure depends on multiple factors, including age, family history, body weight, physical activity, kidney function and existing medical conditions.
The researchers also found that the association persisted in studies that adjusted for body mass index, suggesting that differences in weight alone did not fully explain the results. Similar patterns were observed among participants with Type 2 diabetes and among adults without that diagnosis, although the investigators acknowledged limitations in the underlying research.
Five of the six studies were cross-sectional, meaning they assessed participants’ eating habits and blood pressure during a particular period rather than following them over an extended time. Only one was a prospective cohort study. Consequently, the analysis could identify an association between breakfast habits and hypertension but could not establish which came first or whether other lifestyle factors contributed to the findings.
The research nevertheless raises questions about whether regularly extending the overnight fasting period affects biological processes involved in controlling blood pressure. Scientists have focused particularly on cortisol, a hormone produced by the adrenal glands that helps regulate metabolism, inflammation, stress responses and cardiovascular function.
Cortisol normally follows a daily rhythm, with concentrations typically rising around waking and gradually declining as the day progresses. This pattern is influenced by the body’s internal clock, sleep schedule, physical activity and other environmental and physiological factors.
Prolonged fasting and irregular eating patterns may affect that hormonal rhythm in some individuals. Researchers have proposed that repeatedly delaying the first meal could alter cortisol activity and potentially contribute to changes in blood pressure regulation.
A study examining cortisol patterns among women who regularly skipped breakfast found differences in stress hormone activity and cardiovascular measurements compared with women who ate breakfast. The investigators observed higher systolic and diastolic blood pressure among habitual breakfast skippers, along with greater cortisol activity during parts of the day and a less pronounced daily cortisol rhythm.
The researchers also found differences in cortisol responses following lunch and during controlled laboratory conditions. Those results suggested that breakfast habits could be associated with activity in the hypothalamic-pituitary-adrenal axis, the biological system that helps regulate the body’s response to stress.
However, the study did not prove that skipping breakfast directly caused the hormonal differences. Cortisol is influenced by numerous factors, and the relationship between eating schedules, hormone regulation and blood pressure remains under investigation.
Elevated cortisol can contribute to higher blood pressure under certain conditions by affecting blood vessel function, sodium balance and the body’s response to stress. Chronically excessive cortisol, as occurs in some endocrine disorders, is a recognized contributor to hypertension.
That does not mean every person who misses breakfast experiences a harmful cortisol increase or that eating immediately after waking necessarily lowers blood pressure. Individual hormonal responses vary, and additional controlled studies are needed to determine whether changing breakfast habits produces measurable cardiovascular benefits.
Cardiac electrophysiologist Dr. Riple Hansalia, director of electrophysiology at Jersey Shore University Medical Center, has identified breakfast skipping as a possible contributor to several cardiometabolic concerns, including high blood pressure, unfavorable cholesterol levels and diabetes risk.
The relationship may involve more than one biological pathway. Prolonged fasting can affect glucose regulation, appetite hormones and subsequent eating behavior, while the nutritional quality of meals consumed later in the day may influence longer-term cardiovascular health.
People who skip breakfast may compensate by eating larger portions during lunch or dinner, consuming more snacks or selecting foods higher in sodium, refined carbohydrates and saturated fat. Such habits could contribute to weight gain or impaired metabolic health over time, although research has not consistently shown that breakfast skipping leads to higher total calorie consumption.
Some observational studies have reported that people who miss breakfast consume approximately 100 additional calories later in the day. Other investigations have produced different results, indicating that the relationship depends on individual appetite, food choices, meal timing and other behaviors.
Researchers have also examined whether skipping breakfast encourages late-night eating, which can influence sleep, glucose metabolism and overall energy intake. Eating patterns that concentrate a large proportion of daily calories in the evening have been investigated for possible associations with cardiometabolic risk, but evidence concerning the effects of specific meal schedules remains mixed.
Weight management is particularly important because excess body fat is a well-established risk factor for hypertension. Higher body weight can increase the workload on the cardiovascular system and contribute to changes in kidney function, inflammation and hormonal pathways involved in controlling blood pressure.
However, the assumption that eating breakfast necessarily prevents weight gain has not been supported consistently by randomized clinical trials.
A 2023 systematic review and meta-analysis examining breakfast skipping and cardiovascular risk factors found that omitting breakfast could produce modest reductions in body weight while increasing low-density lipoprotein cholesterol, commonly called LDL or bad cholesterol.
The review also examined blood pressure measurements from controlled studies and found no statistically significant difference in systolic or diastolic blood pressure between breakfast skippers and breakfast eaters.
Those findings complicate the interpretation of the observational research. While people who habitually skip breakfast may be more likely to have hypertension, instructing people to skip or consume breakfast in controlled trials has not consistently changed blood pressure.
A separate systematic review of randomized clinical trials involving 425 adults similarly found that breakfast skipping produced a small average reduction in body weight and an increase in LDL cholesterol, without significant changes in blood pressure or several other measured cardiometabolic markers.
Together, the studies suggest that breakfast habits may be one component of a larger pattern of lifestyle and metabolic factors rather than an isolated cause of hypertension.
Observational research can detect associations that develop over years, but it is vulnerable to differences among participants that cannot always be fully measured. Randomized trials offer stronger evidence about cause and effect, although many breakfast studies have involved relatively small populations and short intervention periods.
Scientists therefore have not established whether eating breakfast regularly lowers the long-term incidence of hypertension, whether certain populations benefit more than others or whether the nutritional composition of the meal is more important than its timing.
The issue has practical significance because skipping breakfast is common in the United States. National dietary surveys have found that a substantial proportion of adults regularly miss the morning meal, with estimates varying according to age, population and how researchers define breakfast consumption.
Approximately 15% of U.S. adults older than 20 skip breakfast on a given day, according to national figures cited in discussions of the research. Other surveys have produced different estimates, reflecting variations in dietary habits and study methods.
Adults may skip breakfast because of work schedules, limited appetite in the morning, weight-management goals or time-restricted eating practices. Some also avoid eating early because of medication schedules, digestive discomfort or personal preferences.
Intermittent fasting has made intentional breakfast skipping increasingly common among individuals attempting to manage body weight or improve metabolic health. Time-restricted eating plans often concentrate food consumption within a limited daily window, sometimes beginning at noon or later.
Research into intermittent fasting has produced mixed results, with some studies reporting improvements in body weight or selected metabolic measurements and others finding that benefits are largely explained by reduced calorie intake rather than the timing of meals.
For individuals with hypertension, diabetes or other chronic conditions, the effects of fasting may depend on medications, hydration, nutritional intake and the length of the fasting period.
Certain blood pressure medications can contribute to dizziness or low blood pressure, particularly when combined with dehydration or prolonged periods without food. People taking diabetes medications may also need to consider the risk of low blood glucose when changing meal schedules.
Health professionals therefore recommend discussing substantial changes in fasting routines with a clinician, especially when prescription medications or chronic medical conditions are involved.
For adults who prefer eating breakfast, the nutritional quality of the meal may be more important than simply consuming food shortly after waking.
Heart-healthy dietary patterns emphasize vegetables, fruits, whole grains, legumes, nuts, seeds and other foods that provide fiber, potassium, magnesium and calcium. These nutrients contribute to several biological processes associated with normal cardiovascular function.
Potassium helps regulate fluid and electrolyte balance and can reduce some of sodium’s effects on blood pressure. Magnesium participates in muscle and nerve function, including processes affecting blood vessel activity, while calcium supports normal muscle contraction and cellular signaling.
Dietary fiber can help improve cholesterol levels and support metabolic health. Whole grains, fruits and legumes provide fiber while generally containing less sodium than many highly processed convenience foods.
One established approach to blood pressure management is the Dietary Approaches to Stop Hypertension, or DASH, eating plan.
The National Heart, Lung, and Blood Institute’s DASH guidance emphasizes a combination of fruits, vegetables, whole grains, low-fat dairy products, beans, nuts and lean protein sources while limiting foods high in sodium and saturated fat.
Research has demonstrated that the DASH dietary pattern can reduce blood pressure, particularly when combined with lower sodium consumption.
A breakfast consistent with that approach might include oatmeal topped with berries, sliced bananas or other fruit. Oats supply soluble fiber, while fruit contributes additional fiber and a variety of vitamins and minerals.
Plain yogurt served with nuts and berries offers protein, calcium and unsaturated fats. Choosing yogurt without added sugar can help limit unnecessary calorie intake, while unsalted nuts provide minerals and fats associated with cardiovascular health.
Eggs prepared with vegetables provide another option, particularly when served with whole-grain toast or roasted sweet potatoes. Spinach, tomatoes, peppers and other vegetables can increase the meal’s fiber and micronutrient content without substantially increasing sodium.
Smoothies made with leafy vegetables, fruit and milk or unsweetened yogurt can also be incorporated into a balanced breakfast. However, their nutritional value depends on the ingredients and portion sizes, and large amounts of fruit juice, sweeteners or syrups can increase sugar intake.
For people with limited time in the morning, overnight oats, prepared fruit, boiled eggs or yogurt with nuts may provide convenient alternatives to commercially prepared breakfast foods.
The choice of ingredients matters because some breakfast products marketed as convenient or nutritious contain substantial amounts of added sugar, refined starches or sodium.
Processed breakfast meats, packaged sandwiches, pastries and certain breakfast cereals may contribute significant sodium or saturated fat, depending on their composition. Regularly relying on these foods would not necessarily provide the cardiovascular benefits associated with a balanced dietary pattern simply because they are consumed in the morning.
Meal timing is another consideration, although researchers have not established a universal schedule that optimizes blood pressure.
Some nutrition specialists recommend eating within one to two hours of waking, particularly for people who experience pronounced hunger, fatigue or overeating later in the day when breakfast is delayed.
That recommendation may help establish a consistent eating routine, but it should not be interpreted as a proven medical requirement for preventing hypertension. Available evidence does not establish that all adults must eat within two hours of waking to maintain healthy blood pressure.
Individual factors such as shift work, sleep patterns, physical activity and personal preferences can influence the most practical time to consume the first meal.
Consistency may also matter because irregular eating schedules can affect the body’s circadian rhythms, which help regulate sleep, metabolism and hormonal activity.
The relationship between those rhythms and cardiovascular health is an active area of scientific investigation. Blood pressure normally fluctuates throughout the day, often increasing around waking and declining during sleep.
Disruption of normal sleep and circadian patterns has been associated with higher cardiovascular risk, prompting researchers to investigate whether meal timing contributes to those effects.
However, distinguishing the influence of breakfast from the effects of sleep duration, stress, employment schedules and overall diet remains challenging.
The broader importance of blood pressure prevention is substantial. Nearly half of U.S. adults have hypertension under current American clinical definitions, and many do not have their blood pressure adequately controlled.
Hypertension increases the risk of heart attack, stroke, heart failure, kidney disease and other serious conditions. Because it often produces no obvious symptoms, people may remain unaware of elevated blood pressure until routine measurements identify the problem.
Long-term exposure to excessive pressure can damage blood vessels and place additional strain on the heart and kidneys. Effective treatment reduces those risks, making early detection and sustained management important components of preventive care.
The American Heart Association’s guidance on high blood pressure emphasizes regular physical activity, maintaining a healthy body weight, limiting sodium, moderating alcohol consumption and following a nutritious dietary pattern.
Avoiding tobacco and taking prescribed blood pressure medications as directed are also important. People with consistently elevated readings should work with a health professional to determine whether lifestyle changes, medications or a combination of approaches are appropriate.
Adding breakfast cannot substitute for these established interventions.
A person who regularly skips breakfast but otherwise follows a nutritious diet, exercises consistently and maintains healthy blood pressure may not necessarily benefit from forcing an additional meal into the day.
Conversely, an individual who routinely misses breakfast and compensates with high-sodium convenience foods or large evening meals may benefit from changing the overall pattern of food consumption.
The distinction underscores why researchers continue examining the relationship between eating schedules and cardiovascular health rather than treating breakfast as a stand-alone preventive treatment.
The 2022 meta-analysis provides evidence of an association across several populations, but its largely observational design limits conclusions about causation. More recent reviews of controlled trials have not consistently shown that breakfast consumption directly reduces measured blood pressure.
Future studies will need to examine longer intervention periods, different age groups and varying meal compositions to determine whether specific breakfast habits produce lasting cardiovascular effects.
Researchers are also interested in whether individuals with diabetes, obesity, disrupted sleep schedules or preexisting hypertension respond differently to changes in meal timing.
For now, the evidence supports considering breakfast as one possible component of a heart-healthy daily routine rather than a guaranteed means of preventing high blood pressure.
A balanced morning meal containing whole grains, fruit, vegetables, protein and healthy fats can contribute valuable nutrients, particularly when it replaces processed foods or helps establish consistent eating habits.
The strongest evidence for protecting cardiovascular health, however, continues to favor an overall nutritious diet, regular exercise, appropriate weight management, sufficient sleep and effective blood pressure monitoring.
The central finding remains that adults who habitually skipped breakfast had approximately 20% higher odds of hypertension in the 2022 observational analysis. Whether that relationship reflects a direct effect of fasting, associated lifestyle habits or several interacting biological factors has not yet been established.
As scientists continue investigating meal timing and cardiovascular health, the research offers another reason to examine daily eating patterns while reinforcing the importance of established strategies for preventing and controlling high blood pressure.
