When it comes to the contents of your fridge, it just doesn’t feel complete without a can (or 12) of La Croix. But according to new research published in the academic journal Obesity Research & Clinical Practice, the seltzer you’re sipping could actually cause you to eat more than usual throughout the day.
Here’s why: It turns out the carbon dioxide—aka the molecule responsible for those fizzy and refreshing bubbles—actually triggers the release of hunger hormones in your body. As a result, the more carbonated water you drink, the more likely you are to overeat and (eep) gain weight.
OK, so there is one teeny-tiny caveat: So far, the study authors have only tested this theory on rats and men, which means that much more research needs to be done. But in the meantime, you may want to go easy on the pamplemousse.
