  • According to researchers, people whose BMI measurements fluctuate between high and low values ​​are at increased risk of serious cardiovascular disease.
  • Experts say changes in BMI can put additional strain on the heart and other organs.
  • They also add that when you gain weight back, you’re more likely to gain fat around your belly.
  • It is said that there are two ways to maintain your weight at a healthy level: regular exercise and healthy eating.

A high body mass index (BMI) can be associated with a variety of health problems and can ultimately lead to severe cardiovascular disease.

Highly variable BMI was associated with adverse cardiovascular events, according to a new study. BMI fluctuates widely and weight fluctuates repeatedly.

of findings Published in JAMA Network Open: Cardiology.

The researchers analyzed data collected from the Million Veterans Program between 2011 and 2018, and from UK Biobank participants enrolled between 2006 and 2010. Follow-up was on average nearly 4 years.

Researchers reported that increased BMI variation was associated with adverse cardiovascular events, regardless of common cardiovascular disease risk factors or genetic risk.

The researchers said their findings indicate that high variability in BMI may be associated with a high-risk phenotype for cardiovascular disease.

BMI is associated with increased levels of fat (fat) in the body, which can result in many chronic health conditions.

“Central obesity, and thus waist circumference, is known to be an independent risk factor for the development of atherosclerotic cardiovascular disease (i.e., stroke, heart attack, coronary artery disease, peripheral vascular disease), diabetes, and kidney disease. ” said Hosam Hummoud, a cardiology researcher at Northwell Lenox Hill Hospital in New York who was not involved in the study. health line.

Increased levels of adipose tissue cause the body to release pro-inflammatory chemical messengers that promote high cholesterol and inflammation, leading to plaque buildup in the arteries (atherosclerosis) and diabetes. Humud explained that it causes insulin resistance and high blood pressure (hypertension). .

Experts say a BMI within the normal range is an important indicator of overall health for a variety of reasons.

“Excess weight puts additional strain on the heart, circulatory system, and joints of the body,” says Brooke Agarwal, assistant professor of medicine and behavioral cardiology expert at Columbia University’s Valléus College of Physicians and Surgeons in New York. he says. He was not involved in the research.

“Excess adipose tissue can also lead to higher blood pressure, higher levels of triglycerides and cholesterol, and poorer blood sugar control, contributing to an increased risk of developing cardiovascular disease, the leading cause of death worldwide,” Agarwal said. Told. health line.

There is a U-shaped relationship between BMI and overall health.

“Very low or high BMI is associated with increased morbidity and mortality,” said John Higgins, a sports cardiologist at UT Health Houston who was not involved in the study. Ta. health line.

is here General guidelines:

  • The optimal BMI for adults is between 18.5 and 25.
  • BMI less than 18.5 – the person is considered underweight
  • BMI 25-30 is considered overweight
  • A BMI of over 30 is considered obese.

BMI, which is highly variable, may be associated with cardiovascular events in several different ways.

“Each time you gain weight back, cardiovascular risk factors such as blood pressure, cholesterol, and blood sugar levels can rise several centimeters above baseline levels, a phenomenon known as weight gain.”Iterative overshoot theory” said Agarwal.

Additionally, he explained that the weight you lose is usually a mixture of fat and some lean muscle tissue, while the weight you regain is usually all fat tissue.

This fat may be preferentially stored in the abdomen, and abdominal fat is strongly associated with cardiovascular disease risk.

To improve your BMI, Hmoud recommends getting 30 minutes of moderate-intensity exercise at least five days a week.

He also suggests changing your diet to include more Mediterranean-based foods (i.e., olive oil, fish, and vegetables) and seeing your doctor regularly to monitor your weight.

“Lowering BMI reduces the incidence of serious adverse cardiovascular events such as stroke and heart attack by lowering basal levels of inflammation, lowering blood pressure and blood sugar levels, and improving gut health.” It also reduces inflammation,” Hmoud said. “Supplementing a healthy lifestyle with weight loss drugs such as GLP-1 RA (semaglutide) may also be helpful in the setting of refractory weight loss efforts.”

When thinking about BMI, experts say it’s important to consider the big picture in terms of lifestyle and building healthy long-term habits.

“I think this study highlights the importance of trying to achieve a healthy weight in a sustainable way, and that it can be a lifestyle rather than a short-term solution.” “Traditional diets that focus on eliminating entire groups or severe calorie restriction often fail to produce sustained weight loss or health benefits,” Agarwal said.

Strict dieting in the short term can lead to patterns of restrictive eating and overeating in the long term. Eating intuitively and/or consciously is a more achievable approach to weight management and may lead to long-term, modest weight loss and improvements in other physiological parameters such as inflammation. explained Mr. Agarwal.

“We and other researchers have shown that eating the majority of your total daily calories at dinner increases your risk of elevated BMI and blood pressure. “Eating on time may be a good strategy to manage your weight without strict restrictions,” he added.

“You can calculate your BMI by dividing your weight in pounds by your height in square inches and multiplying by 703,” Agarwal says.
