If I had a penny for every time a patient of mine started a sentence with, “How bad is it if I eat_____,” I’d be a millionaire. When we’re asked to make big changes in our diet, we often start negotiating that just a little butter or a cheeseburger every once in a while couldn’t hurt, right? But it actually could. Several studies have shown that a single high-fat meal can immediately increase triglycerides in the body. One particular study found that for individuals that are at risk or already have coronary artery disease, blood vessel function became abnormal 3-5 hours after a high-fat meal, thus immediately increasing the risk for a cardiac event. The best bet is to continue with healthy eating habits, stress management and regular daily exercise. That burger is just not worth it.
