Great News for Keeping Your Heart HealthyHeart health
By Joy Stephenson-Laws, JD, Founder
It’s not news that two of the most important things you can do to help prevent cardiovascular disease are reducing the risk factors associated with having too much body fat, and not exercising enough. The other element of the healthy heart equation is, of course, following a nutritionally balanced diet.
What is news – and what is exciting for anyone concerned about heart health – are two recent studies that may get millions of people who have been discouraged from losing weight or exercising to give them both another try. Given that the National Institutes of Health reports that two out of every three adults is either overweight or obese and that almost one-in-four deaths in the United States are the result of heart disease, anything that may help reduce these numbers is welcome news!
The First Good News: Any Weight Loss is Good Weight Loss!
All things being equal, obesity is arguably one of the greatest threats to cardiovascular health. Carrying excess weight - and especially excess body fat – can trigger a variety of conditions that can increase your risk of developing heart disease or making it worse if you already have been diagnosed with it. These include hypertension, inflammation, metabolic syndrome, high triglycerides, low levels of “good” cholesterol and increased levels of blood sugar.
While research continues on exactly how fat impacts cardiovascular health, there has been general agreement in the medical community that the location of body fat, such as visceral fat attached to your internal organs or fat around the belly, carry a greater risk of cardiovascular disease and premature death than body fat located, for example, in your arms or legs. And this concept of a correlation between fat location and cardiovascular risk is still treated as a given by the healthcare community.
What is news, however, is how fat in other body locations is being viewed and evaluated in terms of cardiovascular risk. For the past eight years doctors have cited research that showed that other fats – especially those around the thighs, hips and backside – could actually reduce the risk of heart disease. As a result, many people focused their efforts – and sweat – on trying to spot reduce belly fat, which is notoriously stubborn to lose. If their efforts failed, their attempts to reduce their body fat often failed with them.
Given this long standing research on “protective fat,” it is totally understandable that people would be concerned if their diets caused them to lose some of this “good” fat rather than their “bad” belly fat. The biggest concern these dieters had was whether or not losing this “good” fat would improve their cardiovascular health or inadvertently increase their risk of heart disease.
Researchers tracked dieters and measured such important risk factors as glucose, insulin, cholesterol and blood pressure of those who lost the “protective fat” during their dieting to see what impact, if any, it had on heart health risk factors. The results? Researchers found that losing fat - and even some muscle – in the thighs, hips and buttocks resulted in beneficial changes in heart disease risk markers. Put another way, it means that any weight loss – whether from your backside, belly or legs – reduces your cardiovascular risk factors. And for lowering your cholesterol, losing fat in your legs is just as important as losing it around your belly.
If this isn’t good enough news for people trying to lose weight, the study also showed that losing some lean tissue in the thighs, hips and backside did not present any health risks. This is important since rather than trying to lose weight and maintain muscle mass at the same time, you can focus on getting rid of some of your excess weight and body fat first and then work on increasing muscle mass later.
There is, however, one caveat. While it’s now becoming clear that any weight loss is good, a couple of pounds really won’t do the trick when it comes to heart health – especially if you are seriously overweight. To really enjoy the cardiovascular benefits of weight loss, you need to lose at least five to 10 percent of your total body weight to have a positive impact on blood pressure, glucose tolerance and cholesterol.
Another thing to keep in mind as you continue, or perhaps restart, your program to reduce your body fat is that multiple research suggests that your percent body fat is a better predictor of your overall cardiovascular risk than other metrics such as your body weight or your body mass index (BMI). Knowing your percentage is especially important since you could be what is considered a normal weight but yet still have dangerous levels of body fat. Researches are also starting to see evidence that the density of your fat is important as well, with lower density fat being associated with worse heart disease risk factors. Your doctor or healthcare provider can do tests to determine both your percentage body fat and its density.
Even More Good News: Any Exercise is Good Exercise!
Just like we all know that being overweight is not good for our hearts, we also know that exercise is good for it. The benefits for our cardiovascular system are many and they include lowering blood pressure, decreasing our heart rates, strengthening the heart muscle itself, reducing the risk of metabolic syndrome, and lowering blood sugar levels. So, why more than half of adults over 18 get the recommended amount of aerobic exercise a week with even fewer doing equally important strength training? We all have our favorite reasons, but the most common usually are “I don’t have the time” and “I am not in good enough shape.”
Another is “it won’t do me any good since heart disease runs in my family.”
New research debunks these three beliefs and turns them on their heads. The first takeaway from the study is that even if you have a genetic risk for heart disease, exercise clearly lowers your risk of developing it compared to the risk of not exercising. How much did it reduce the risk? For both men and women, a high fitness level was linked to a 49 percent lower risk for coronary heart disease and a 60 percent lower risk for atrial fibrillation, which can increase the risk of stroke and heart failure. Other recent research is confirming that people who may already have heart disease tend to live longer when they exercise.
The good news is that you don’t need to become a marathon runner, champion weight-lifter or Olympic contender to enjoy the cardiovascular benefits of exercise. The American Heart Association suggest getting at least 150 minutes per week (about 20 minutes a day) or moderate exercise or 75 minutes a week or vigorous exercise, or a combination of both to help protect your heart. This is not very time consuming and the great news is that you get benefits if you break your exercise down into two or three chunks of 15 – 20 minutes each per day.
And if you’re still thinking you need to summit a mountain, for the above recommendations, physical activity is defined a anything that makes you move your body and burn some calories. This includes climbing stairs, walking, or riding a bike.
So, given that any weight loss and any physical activity can reduce your risk of cardiovascular disease, what are you waiting for? Be proactive and get moving!
