First off, how does something the body needs to function become bad for your health? Let’s first look at where triglycerides come from.
When you eat, your liver converts the calories your body doesn’t need to use right away into triglycerides, which then get stored in fat cells, explains Michael Shapiro, D.O., a cardiologist at Wake Forest Baptist Health in Winston-Salem, NC.
When you have a balanced diet, your triglyceride production is usually balanced, too. But if you regularly overeat, those levels will continue to climb. “And if triglycerides are high enough for long enough, they can deposit in areas where they’re not intended,” says Dr. Shapiro. And that’s when they endanger your health.
