What it means: There’s no standard definition for this term, so it can mean any number of things―or nothing at all.
The health implications: There’s no evidence that low-carb diets are more effective long-term than any other diets. Also, some carbs, like whole grains and produce, are healthier than others, and this term doesn’t distinguish between “good” and refined carbs.
Keep in mind: Manufacturers often replace those “missing carbs” with high-fat ingredients (such as nuts), sugar alcohols, or artificial sweeteners, so sometimes low-carb foods have just as many calories as foods that are not low-carb.
Bottom line: Disregard this label and pick foods that are healthy for what they do contain―vitamins, nutrients, and fresh ingredients.
