‘Keto Crotch’ isn’t the only gross side effect of a popular diet

Low-carb diets, like keto, paleo or carnivory, can give you the runs. “We need soluble fiber… to bind food in the system,” Brondo says. The lack of it makes our stool less solid, Brondo explains.

“It’s relatively common,” but that doesn’t mean it’s a good thing, she says. “[It’s] totally not healthy.”

And while some people’s digestive systems might adjust over time, others may not be so lucky. In addition to the dreaded discomfort, repetitive bowel blowouts can affect the way your body absorbs vitamins and minerals.

“It’s a sign you need to add those carbs back in,” Brondo says.
