"This is a wake up call", said a cardiologist. Very well put. In a nutshell, the arteries of obese children and those with problems in their blood fats (for example, cholesterol, LDL, HDL, triglycerides) resemble those of middle-age adults (45-year-olds!) and could indicate rapidly impending cardiovascular disease (for example, early heart attacks, strokes, etc). More studies will determine if this is reversible once the weight is lost and blood fats are improved. We are hopeful that future studies will show this.
