The Claim
Individuals following a self-selected low-carbohydrate, high-fat diet consume significantly lower dietary fiber than individuals following vegan, vegetarian, or omnivorous diets, with only 8% of those on the low-carbohydrate, high-fat diet meeting recommended dietary fiber intake levels, despite achieving similar micronutrient adequacy due to supplement use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat low-carb, high-fat diets tend to eat way less fiber than vegans, vegetarians, or meat-eaters, and only 8% of them get enough fiber — but they still get enough vitamins because they take supplements.

What the research says
1 studyStudy: Habitual low carbohydrate high fat diet compared with omnivorous, vegan, and vegetarian diets
People eating low-carb, high-fat diets ate way less fiber than those on vegan, vegetarian, or regular diets, even though they got enough vitamins—probably from supplements. This matches what the claim says.
