Prevent heart attack - reduced calorie intake protects the heart

Reducing calories increases heart health

Excessive calorie intake combined with sedentary lifestyle are the main causes of obesity and obesity. The result is a significantly increased risk of heart disease. But even in people who are not overweight, reducing calories can improve heart health, reports Dr. Stephen Kopecky, cardiologist at the prestigious Mayo Clinic in the United States.

Overweight is a significant additional burden on the cardiovascular system and even below the limit of overweight, the risk of heart disease increases due to excessive calorie intake, explains the expert. Limiting calorie intake, for example, could significantly reduce the risk of a heart attack. And the risk of other diseases is also significantly reduced. By adjusting the portion sizes and selecting suitable foods, the calorie intake can be reduced relatively easily.

Avoid 200 to 300 kilocalories

According to the expert, excessive calorie intake is one of the main reasons for the obesity epidemic in the United States. "The average American eats about 400 to 500 kilocalories more than before," emphasizes Dr. Kopecky. Those who do without 200 to 300 calories a day are likely to reduce their daily intake of carbohydrates and fat, the cardiologist continues. For most healthy adults, reducing calories a little can be very helpful.

Every additional kilo needs blood vessels by the kilometer

With every pound of weight (around 2.2 kilograms) we gain, there are five miles (around eight kilometers) of additional blood vessels, reports Dr. It's easy to figure out that if you are ten pounds overweight, it will put a lot of strain on your heart. "The heart gets tired, blood pressure and heart attack rates rise, etc.," said the cardiologist.

Simply lower your calorie intake

According to the expert, an easy way to reduce the calorie intake is to adjust the portion sizes and switch to foods based on the Mediterranean diet, with lots of vegetables, fruits, whole grains, fish and olive oil. Even a slight reduction in calorie intake not only reduces the risk of a heart attack, but also the risk of strokes, diabetes, some types of cancer and Alzheimer's.

Judge values ​​for calorie intake

The German Society for Nutrition (DGE) for adults with a mean body mass index (BMI) of 22 cites a daily energy intake of 2,300 kilocalories for men and 1,800 kilocalories for women as judge values ​​for the daily calorie intake. However, these values ​​only apply when there is little physical activity and at the age of 25 to 50 years. For example, the guideline values ​​are significantly higher during high physical exertion and during pregnancy. (fp)
