The faster you eat, the more difficult it is for the hormone insulin to do its work in your body. That means that fewer nutrients reach your muscles, and it is likely that more get deposited in your fat reserves. In the long term this leads to a much higher chance of being overweight and developing type two diabetes.
Researchers at the Lithuanian University of Health Sciences in Clinical Nutrition discovered that fast eaters were twice as likely to have type two diabetes than slow eaters. The researchers corrected for factors such as genetic predisposition, BMI, waist measurement, education, smoking, the amount of triglycerides in the blood and physical exercise.
Previous studies have already shown that fast eaters are more often overweight than slow eaters. If you eat fast, you tend to eat more; if you eat slowly, you eat less. That’s probably because the digestive system produces all sorts of appetite suppressing hormones while we are eating. Production of these hormones is slower in fast eaters. Apparently these hormones also ensure that the hormone insulin can do its work.
