The Claim

Severe and long-term dietary carbohydrate restriction in adults causes secondary deficiencies in intestinal brush-border enzymes such as sucrase-isomaltase, which impairs small intestinal digestive function and leads to malabsorption and gastrointestinal symptoms.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Eating very few carbs for a long time might reduce the digestive enzymes in your gut, making it harder to break down food and potentially causing stomach issues and nutrient problems.

See the scientific wording

Severe dietary carbohydrate restriction in adults can result in secondary deficiencies of intestinal brush-border enzymes, including sucrase-isomaltase. This clinical observation indicates that long-term adherence to low-carbohydrate diets may impair digestive enzyme function in the small intestine, potentially leading to malabsorption issues and gastrointestinal symptoms in susceptible individuals following such dietary interventions.

What the research says

1 study

  1. Study: Adult onset sucrase-isomaltase deficiency with secondary disaccharidase deficiency resulting from severe dietary carbohydrate restriction

    The study confirms that cutting out most carbohydrates from an adult's diet can actually cause a drop in important digestive enzymes in the gut, which matches the claim exactly.
