While BMI may not tell the whole story when it comes to weight, it is widely used as a metric to determine overweight and obesity. WR led to significant decreases in BP at rest from Even small reductions in weight can make a big difference In a study Withings conducted with Georges Pompidou Hospital in Paris, researchers found that a decrease in BMI of 1.

Blood pressure and weight -

No specific recommendations regarding sodium intake were provided. The participants were invited to the follow-up examination 12 weeks after dietary counseling. If they failed to achieve their target weight, additional dietary and motivational counseling was offered, and the follow-up examination was postponed for 12 weeks.

After 24 weeks, all study participants were invited to the follow-up examination regardless of whether they had successfully reduced their weight. Before the follow-up examination was performed, a weight stabilization period of at least 2 weeks was obligatory.

During this stabilization period, the participants ate a mixed diet according to their energy needs that is, energy intake corresponded to the energy requirements. Through this stabilization period, a theoretical effect of the diet on BP and other measured parameters on the test day was minimized.

The follow-up examination was identical to the baseline examination and comprised measurements of BP, heart rate, weight and fat mass. Identical to the baseline examination, two subsequent exercise tests were performed with random allocation of an external weight vest to one of the two tests.

Data were analyzed using Stata software Stata For continuous variables, means and s. are provided. The Mann—Whitney rank-sum test was used for non-normally distributed continuous variables.

Changes in BP, BW and body fat percentage between the baseline and follow-up examinations were calculated. Multiple linear regression models were used to evaluate associations between systolic BP, diastolic BP or heart rate dependent variables and independent variables wearing a weight vest, BW and body fat percentage.

An a priori sample size calculation was performed based on data from a previous study. Of all eligible volunteers who were asked to participate in the study, four were excluded three refused study participation and one had a history of a cardiovascular event Figure 1.

Twenty-three volunteers underwent the baseline examination. Six volunteers failed to lose weight, resulting in 17 study participants who completed the study protocol. The baseline characteristics of the study participants are shown in Table 1.

The mean age was Nearly half of the study participants The mean body mass index was The prevalence of cardiovascular risk factors was low, and only one study participant was on a prescription for an antihypertensive drug Table 1.

There were no significant differences in baseline characteristics between the study participants and the six volunteers who failed to lose weight. Between baseline and follow-up, weight decreased from The mean WR was Accordingly, the body mass index decreased from Waist circumference decreased from The mean resting BP from the three measurements on each arm of the sitting participants decreased from The mean systolic BP decrease was The mean diastolic BP decrease was 6.

The BP and heart rate measurements during the bicycle exercise tests at baseline and follow-up are shown in Table 2. BW reduction was associated with significant decreases in BP at rest and during exercise regardless of whether the study participant was wearing an external weight vest. Effects of BW reduction on heart rate were less evident.

Wearing a weight vest was associated with significant increases in systolic and diastolic BP at rest and during exercise before and after WR, whereas there was no evidence of an effect on heart rate. Figure 2 shows the systolic and diastolic BPs before and after WR and with and without an external weight vest, respectively.

Wearing an external weight vest after WR led to systolic and diastolic BPs comparable to the BP values found without a weight vest before WR.

Systolic and diastolic blood pressures BPs during a bicycle exercise test before and after weight reduction and with and without an external weight vest. Between baseline and follow-up, heart rate during the resting electrocardiography significantly decreased from The h electrocardiography recording revealed that the heart rate reduction after WR was predominantly a reduction of resting heart rate and heart rate during sleep heart rate during sleep decreased from No significant change in the electromechanical activation time was found.

The associations of the independent variables wearing a weight vest, total BW and body fat percentage with BP and heart rate during bicycle exercise testing in a multiple linear regression are shown in Table 3. There was strong evidence for an association between the weight vest and BP at rest and some evidence for its association with BP during exercise.

There was also strong evidence of an independent association between body fat percentage and systolic and diastolic BPs at rest and at all levels of exercise. The evidence for an association between total BW and BP was weaker, whereas the association between BW and heart rate was stronger.

Six study participants failed to lose BW. Failure to lose weight in these participants was due to a lack of motivation and psychological stress factors. There were no significant differences in their baseline characteristics compared with the 17 study participants who completed the study protocol.

Three of these six study participants also underwent the follow-up examination. Their BW remained unchanged change from There were no significant differences in BP or heart rate at rest or during exercise between baseline and follow-up.

Wearing an external weight vest uniformly led to increases in systolic BP of up to This study revealed several findings. First, systolic and diastolic BPs at rest and during exercise and heart rate at rest decreased with WR.

Second, wearing an external weight vest led to an immediate increase in systolic and diastolic BPs at rest and during exercise. Third, the increase in BP induced by wearing an external weight vest was independent of BW or body fat.

This study is in agreement with findings from previous studies reporting a marked BP decrease after WR. This study is the first to provide evidence that wearing an external weight vest leads to an immediate increase in BP at rest and during exercise.

Using the results of this study, the authors can only speculate on potential mechanisms for these findings. Presumably, only sympathetic nervous system activity accounts for these rapid BP changes.

In fact, previous studies have shown that sympathetic nervous system activity is involved in rapid BP changes, for example, in diurnal BP variation and white coat hypertension.

If sympathetic activity had a key role in the rapid BP increase caused by an external weight vest, a more pronounced effect of the weight vest on heart rate would have been expected. Other potential mechanisms explaining the relationship between the weight vest and BP, such as renin—angiotensin—aldosterone system activation or changes in blood volume, are rather improbable, considering the time delay required for changes in such mechanisms.

This study also supports the findings from other studies underscoring the important effect of body fat on BP. This study had several limitations. First, it comprised healthy volunteers. The results of this study may therefore be generalized only with caution to hypertensive or otherwise comorbid patients.

Second, the sample of 17 study participants was rather small. However, the sample size calculation performed a priori suggests that the sample size was not too small to provide reliable results for nearly all study questions under investigation.

The occurrence of type II error is conceivable in some of the nonsignificant results of this study, particularly diastolic BP during exercise. Third, some of the significant results of this study might be the consequence of using multiple testing and of a lack of a priori primary end point definition.

However, we preferred not to adjust for multiple comparisons to minimize interpretation errors, as the data are not random but actual observations in nature. Indeed, the observed effects of WR on BP are the result of caloric restriction, not exercise, because according to the study protocol, WR had to be achieved through diet and not an increase in exercise level.

Fifth, according to current evidence, BP measurement during exercise may be imprecise for several reasons. In particular, measured diastolic BP may be lower than true diastolic BP.

The results of this study have important clinical and research implications. First, this study supports the need for BW reduction in overweight subjects to diminish their cardiovascular risk burden.

Further research is needed to clarify these mechanisms. Such a future study should assess rapid changes in sympathetic activity in addition to rapid BP changes and should also assess the efficiency of physical exercise for example, by measuring VO 2 consumption and lactate during exercise.

Furthermore, h ambulatory BP monitoring should be performed to identify potential differences in nighttime BP decreases, and the long-term effects on BP of a WR lasting longer than 12—24 weeks should be investigated.

In conclusion, this study demonstrated that a moderate WR through caloric restriction led to a marked decrease in systolic and diastolic BPs at rest and during exercise in healthy subjects. Wearing an external weight vest resulted in an immediate increase in resting BP and exercise BP, independent of BW or body fat, thereby questioning the established physiologic mechanisms of the relationship between weight and BP.

Body mass index and stroke incidence in a Japanese community: the Hisayama study. The sympathetic nervous system or SNS is a network of nerves that allows our brain to control blood pressure by adjusting the diameter of peripheral arteries through electrical impulses.

In obese people, fat cells and insulin resistance tends to stimulate this sympathetic response. Activation of the sympathetic nervous system has been considered to have an important function in the pathogenesis of obesity-related hypertension.

Source: "Mechanisms of obesity-induced hypertension," Hypertension Research, Too much visceral fat—the fat that is stored around the abdomen—can lead to abnormal compression of the kidneys or even a kidney injury that may progress.

Source: "Obesity, kidney dysfunction and hypertension: mechanistic links,"" Nature Reviews Nephrology, These fat cell tissues secrete many hormones. In the kidneys, they can disrupt the renin-angiotensin-aldosterone system or RAAS responsible for sodium salt balance.

The kidney must therefore maintain a higher blood pressure to excrete the daily intake of salt. The association of VAT accumulation with high blood pressure can be confounded by several factors, including age, gender, degree of obesity, and glucose tolerance status; each of these factors has been shown to be related to both abdominal obesity and hypertension.

When you are overweight or obese, the extra fat also increases vascular resistance , as well as the work the heart has to do to pump blood. This extra activity puts extra strain on your heart and causes higher blood pressure. Extra weight can exacerbate other risk factors , such as high cholesterol and insulin resistance, that affect heart health.

Insulin resistance is a particularly insidious cycle—the more fat you have, the more insulin resistant you become, causing you to secrete more insulin, causing you to store more fat. So blood pressure and diabetes are also linked. Medical research to investigate many other possible relationships between excess body fat and high blood pressure is ongoing.

The CDC, too, has said that obesity increases the risk for heart disease and stroke —leading causes of death in the U. The narrower the blood vessels, the greater the workload and the greater risk of heart failure. High blood pressure can lead to an enlargement of the heart's left atrium, which then contracts abnormally.

The resulting pulse disturbance is called an arrhythmia. Also, activity of the renin-angiotensin-aldosterone system RAAS , as seen in people with obesity-induced hypertension can also lead to AFib.

If high blood pressure is not treated, the accumulated pressure on the walls of the arteries can make them more vulnerable. This is called arteriosclerosis, when the arteries become narrowed and promote the accumulation of plaque.

Coronary artery disease occurs when the arteries that supply blood to the heart are blocked. A study published in the European Heart Journal showed that as BMI and fat mass increase, so does the risk of aortic stenosis , a condition in which the valve controlling the blood flow to the aorta fails to fully open.

A joint statement from the European Association for the Study of Obesity and the European Society of Hypertension indicates that obese patients are prone to arterial hypertension , require more medication, and have an increased risk of becoming treatment-resistant.

High blood pressure is one of the leading cause of strokes, especially if it's associated with obesity. Indeed, excess fatty tissues cause reactions and inflammations that enhance the attachment of particles causing generation of clots in the already weakened brain arteries.

If the brain is no longer irrigated, enough with oxygen-rich blood, the brain cells will begin to die. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. Experts are clear: weight reduction can be crucial to lowering hypertension.

Another publication in the Journal of Family Practice, the authors noted that a weight loss of 4kg via a change in diet reduced systolic blood pressure by 4. In addition, they noted that weight loss of 1 to 1.

Many experts suggest setting SMART goals—specific , measurable, attainable, relevant, and time-bound goals—to achieve long-term weight loss.

You might also think in terms of process goals—e. losing a certain number of pounds. In addition, consider body composition —your percentages of fat, water, and bone mass.

Scheme: Example of a reasonable weight loss achievement while setting SMART weight goals. In a study Withings conducted with Georges Pompidou Hospital in Paris, researchers found that a decrease in BMI of 1. The researchers state that the lower blood pressure probably results from an increase in insulin sensitivity and a decrease in the activity of the sympathetic nervous system.

The National Heart, Lung, and Blood Institute has issued guidelines that include lifestyle adjustments to help prevent and treat hypertension. And in an article published in the Journal of Family Practice , researchers conducted a meta-analysis of 8 randomized controlled trials with a total of patients.

They found that weight loss achieved through diet changes reduced blood pressure in hypertensive patients. High blood pressure during pregnancy can be dangerous. It may lead to decreased flow of blood to the placenta, placental abruption in which the placenta separates from the inner wall of your uterus before delivery , premature delivery, and cardiovascular disease, among other risks.

Excess weight during pregnancy may play a role in the development of high blood pressure. A study published in Revista de Saúde Pública found that in pregnant women with excessive weight gain had higher mean systolic blood pressure at the beginning of the third trimester, compared to women with adequate or insufficient weight gain.

A study in Hypertension and Metabolic Syndrome suggests entering pregnancy at a lower BMI, avoiding weight gain, and taking low-dose aspirin. The researchers suggest that home monitoring of blood pressure may also be helpful. Consider lowering your blood pressure by aiming for realistic weight goals and increasing your activity levels to establish a healthy weight.
