(New Scientist) Weight-loss surgery not only rids people of their fat, it may also abolish alcohol cravings.
Some people choose to lose weight by going under the knife to decrease the size of their stomach. One such surgery - the Roux-en-Y procedure, or "gastric bypass" - involves stapling the stomach to leave a small pouch at the top, which is then connected to the small intestine. Food then bypasses most of the original stomach and a chunk of the intestine too. This significantly reduces the amount of food a person is physically able to eat and the amount of nutrients they can absorb.
