The Claim

Consuming a high animal fat diet (approximately 152 grams per day) for four weeks significantly increases total fecal fatty acid excretion to approximately 3.1 grams per day compared to a low animal fat diet (approximately 62 grams per day) in healthy young adults, demonstrating that excessive dietary fat intake overwhelms colonic absorption capacity.

Source: Influence of diets high and low in animal fat on bowel habit, gastrointestinal transit time, fecal microflora, bile acid, and fat excretion.

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

Eating a lot of animal fat makes your body poop out more fat than usual. When healthy young adults ate about 152 grams of animal fat daily for a month, they excreted nearly three times as much fat in their stool compared to when they ate only 62 grams, showing that the gut can only absorb so much fat before the rest passes through.

See the scientific wording

A high animal fat diet (approximately 152 grams per day) significantly increases total fecal fatty acid excretion to approximately 3.1 grams per day, compared to approximately 1.14 grams per day on a low animal fat diet (approximately 62 grams per day), in healthy young adults over a four-week period, indicating that excessive dietary fat intake directly overwhelms colonic absorption capacity.

What the research says

1 study
  1. Study: Influence of diets high and low in animal fat on bowel habit, gastrointestinal transit time, fecal microflora, bile acid, and fat excretion.

    The study confirms that eating a lot of animal fat (152g daily) causes significantly more fat to pass through the digestive system and out in stool compared to eating less fat (62g daily) over a month.
