Every one in two people is overweight or obese in the US. Obesity in itself is very dangerous, but it can also lead to several other chronic diseases. Obese people have a lot more chance to suffer from a heart attack, diabetes, coronary artery disease, or a stroke, all of which are a consequence of increased weight. Extra fat in the body can get stored under the lining of the arteries and form a blood clot which can result in a stroke or a heart attack.
