The Claim

Adults following carnivore diet meal plans consume less than 1 gram of dietary fiber per day, which is substantially below the World Health Organization's recommended minimum of 25 grams per day, and these diets are consistently deficient in vitamin C, vitamin D, calcium, magnesium, and potassium, leading to a high risk of micronutrient inadequacy even when a variety of animal-based foods are included.

Description
1 study reviewed
In plain English

If you're eating only meat on a carnivore diet, you're probably getting almost no fiber and missing key vitamins and minerals like vitamin C and potassium, which could put your health at risk over time.

See the scientific wording

Carnivore diet meal plans for adults provide less than 1 gram of dietary fiber per day, far below the WHO-recommended minimum of 25 grams, and are consistently deficient in vitamin C, vitamin D, calcium, magnesium, and potassium, indicating a high risk of micronutrient inadequacy even with varied animal food inclusion.

What the research says

1 study
  1. Study: Carnivore Diet: A Scoping Review of the Current Evidence, Potential Benefits and Risks

    The study looks at the carnivore diet and finds it can lack important nutrients like vitamins and fiber, just like the claim says.
