There are often big bucks spent on a study to prove or disprove something. Sometimes I scratch my head, as the answer is blatantly obvious from the beginning.
This holds true with a study I read about how giving mice alcohol caused them to eat more that they usually would. But what did surprise me was that it was not because of a loss of restraint, but rather a neural response. It seems the same neurons that are fired when a body experiences starvation are also stimulated when you have a few drinks.
When these neurons were blocked, the mice did not eat as much, even when given alcohol.
If you are watching your waistline, you should be mindful of your eating when enjoying alcohol. But also keep in mind alcohol itself is usually packed with calories. A nice pour from the wine bottle is equivalent to eating a doughnut.
