Eating fewer carbs: It’s the foundation of a number of popular diet trends including Atkins, Paleo and that other dumb one your annoying friend always talks about. But though these diets may help some people lose weight, as Thrillist recently wrote about, they can also have a rather annoying side effect… beyond people’s need to constantly talk about them. Low carb diets can also cause bad breath.

If dieters keep their carbohydrate consumption below a certain level, they cause their bodies to enter a state of ketosis. The good news is that this metabolic state burns fat. The bad news is that the resulting ketones (byproducts of breaking down fat) also get released in your breath causing you to reek out of your face hole. And that’s just part of the problem. “The initial period of water loss in the body in the early stages of a low-carb diet can lead to dry mouth, another source of bad breath,” Dr. Wayne Aldredge, President of the American Academy of Periodontology, told Thrillist.

If there’s a positive to all this, besides the potential weight loss, cutting carbs may be good for your oral health in general. “Foods high in sugar and carbohydrates can create acidic environments in the mouth,” Dr. Aldredge continued. “The bacteria that can lead to periodontal disease thrive in these kinds of environments, feeding off of the sugar that lingers from the food we eat.”


So now the question becomes would the partner of your dreams prefer that you be thin with good oral hygiene but have the breath of a wildebeest or would they rather be in a relationship with a person who has but looks like a walking potato sack? Dating is so hard!
