After you have been out on a binge you may notice that once your appetite for alcohol has stopped, your appetite for food kicks in. Ever wonder why? The reason is simple.
When you drink alcohol it is essentially filled with carbohydrates. As you take in all those carbs, they are turned into sugar in your body. That sugar goes into your blood and raises your blood sugar level.
This happening triggers your body to release more insulin, to deal with all the sugar. Doing its job, the insulin lowers the blood sugar level.
Since you have stopped drinking, your blood sugar level is staying down from the insulin. Now, your body wonders why the blood sugar has dropped and decides to remedy the situation by sending out hunger pangs that tell you to eat more so your blood sugar can get back to the regular levels.
