People who have weight loss surgery can experience changes in appetite and their senses of taste and smell can actually change, according to a new study. Researchers suggest those changes can lead people to lose even more weight.

The study was done in Britain where 97% of patients said their appetite changed after surgery. More than 70% said their sense of taste changed and 40% said their sense of smell changed as well. The changes left them disliking foods they'd enjoyed before surgery. Researchers found that those patients lost nearly 18 more pounds, compared to those whose taste wasn't affected.

The study is published online in the journal "Obesity Surgery."
