What? You’ve never heard of tiger nuts? Most people haven’t. These slightly sweet, slightly chewy tubers (yes, they’re tubers, not even nuts) with a mild nutty, earthy, vanilla flavor look like shriveled chickpeas and come from northern Africa. So are they really the stuff dieters’ dreams are made of? We investigate.  For starters, tiger nuts are superhigh in  fiber, which has been getting for its weight loss benefits, says Gina Consalvo, RD. Resistant starch passes through the stomach and small intestine without being digested, and may even help you lose weight by reducing blood sugar spikes and keeping you fuller longer than other foods with the same number of calories, she says. It also benefits your gut by acting as a prebiotic, stimulating the growth of good bacteria in the digestive tract.

For some context, a serving of almonds—about 23 nuts—has 163 calories and about a third of the filling fiber of tiger nuts. The pitfalls: There aren’t too many, unless you have digestive issues such as IBS or are sensitive to high-fiber foods, says Consalvo—in those cases, you might experience some gas, bloating, cramping, or diarrhea if you eat too many tiger nuts.
