If you skim a list of fad diets from the past few decades, you might notice a trend: Carbs are the enemy. The South Beach Diet, the Atkins Diet, and the keto diet all encourage severe carb restriction to help you (allegedly) lose weight.

With these trendy low-carb diets, it’s tempting to assume all carbs are unhealthy. After all, sugar and soft pretzels are carbs, right? Most experts have spoken against this carb-cutting approach, but a 2018 study may now be able to provide more evidence to put out the low-carb fire.
