Coronary artery disease or heart disease is caused by atherosclerosis, a process which involves the accumulation of cholesterol plaques in the arteries that supply blood to the heart. These plaques can narrow the blood vessels and reduce blood and oxygen delivery to the heart, leading to symptoms like chest pain (ischemia). The plaques can also rupture and form a blood clot, blocking oxygen delivery and causing a myocardial infarction—a heart attack.

February is American Heart Month, with a focus on encouraging all of us to make heart-healthy choices to reduce cardiovascular disease risk. I thought that sharing some information about the heart, how it works, and how to keep it healthy would be an appropriate way to celebrate. This is also the topic of my Health & Fitness column in the Aiken Standard this week.
If you are starting out 2019 by trying to lose weight, you are probably interested in finding the “best” diet. Unfortunately, there is no best diet for everyone, but there are some characteristics that you should look for in a diet. For example, a weight loss diet should be low (but not too low) in calories, reduce added sugar and excess carbohydrates, restrict portion sizes, emphasize healthy foods like fruits and vegetables, and promote healthy eating habits.
Real weight loss success depends on more than selecting the right diet. In fact, as long as your diet is low in calories, you will lose weight. However, this weight loss may be temporary and you, like many others, will gain it back later. There are factors beyond the specific diet you follow that are critical for losing weight and keeping it off. Since successful weight loss requires regular exercise, these same factors apply to exercise behaviors, too.
The benefits of regular exercise include increased endurance, strength, and flexibility along with increased energy expenditure for weight loss and weight maintenance. These benefits will vary depending on the type of exercise you perform.
Endurance (aerobic) exercise will improve your cardiorespiratory fitness and endurance. These improvements allow you to exercise at a higher intensity or for a longer duration. Aerobic exercise like walking or jogging is also effective for burning calories.
Resistance training (weight lifting) will improve your muscular strength. The practical benefit is that you will have an easier time completing physical tasks at work or at home, something that is increasingly important as you get older.
Ideally, your exercise program will include a combination of endurance and resistance training. But there is another type of exercise that you should also include—stretching. This is the topic of my Health & Fitness column in the Aiken Standard this week.
You are probably aware that eating too much sugar is bad for your health. Excessive sugar intake causes hormonal changes and inflammation that can lead to obesity, diabetes, heart disease, and cancer. For decades an emphasis was placed on lowering fat intake, especially saturated fat and cholesterol, to reduce the risk of obesity and heart disease.
Unfortunately, much of this advice was misguided and while fat intake went down, sugar consumption in processed and prepared food increased. This is now seen as a primary cause of the current obesity and diabetes epidemic. The impact of sugar on health and steps you can take to reduce sugar intake are the topic of my Health & Fitness column in the Aiken Standard this week.
There are numerous community and workplace weight loss competitions and fitness challenges underway in our area right now. These programs are a popular way to start making health improvements with friends or coworkers. Many people find the competition aspect of these programs to be motivating. Even those who are reluctant to start a diet or exercise program are more likely to give it a try. But this raises the question, are “biggest loser” type weight loss programs effective at promoting lasting weight loss? This is the topic of my Health & Fitness column in the Aiken Standard this week.
Getting out of debt is a worthwhile goal and a common New Year’s resolution. This almost always means financial debt, which is a burden for millions of Americans. Many individuals and families have gotten themselves into debt by spending too much and not saving enough. For most, this situation has been years in the making, has no simple solution, and will have an impact lasting years into the future. Reducing this debt is essential for achieving financial health.
This is not the only type of debt we face—many people are also in health debt. Poor eating habits and increasingly sedentary lifestyles have led to an obesity epidemic. The problem is widespread, since most Americans are overweight, fewer than half of US adults meet minimum recommendations for physical activity, and about one in six adults smoke. Alone and especially in combination, these poor health habits are the major causes of the most common, and preventable, diseases including diabetes, heart disease, and some cancers.
Even if we have not been diagnosed with diabetes or heart disease or other health problems, our lifestyle has put us on that path. Small changes in what we eat or how active we are have added up over the years to create a condition of poor health. And our overall health and potential complications get worse year after year, so the longer we are overweight and inactive, the worse our health is likely to be in the future. That is our health debt. This is the topic of my Health & Fitness column in the Aiken Standard this week.
