It’s already been established that eating too often is bad for you in many ways, now experts are explaining what time of the day should be a big no-no to eat. Dr. William Kraus, a preventive cardiologist at Duke Health and professor at Duke University School of Medicine, says it’s healthiest not to eat after dinner. Kraus explains that food eaten late in the day or just before bedtime is just going to get stored rather than burned for energy. So what happens to the body if you eat too much at night? You’ll have a higher risk of obesity, high cholesterol and heart disease, and progression of arterial stiffness.
