The Claim

A dietary intervention increasing animal fat intake to approximately 152 grams per day does not significantly alter bowel habits, fecal weight, mean gastrointestinal transit time, or dry matter excretion in healthy young adults over a four-week period, indicating that dietary fat alone does not drive overall colonic function changes.

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

Cause and effect
1 study reviewed
In plain English

Eating about 152 grams of animal fat a day for a month doesn't change how your digestive system works or how much you poop. This shows that just eating more fat isn't what causes changes in your gut movement, so other parts of your diet are probably responsible.

See the scientific wording

Increasing animal fat intake to approximately 152 grams per day does not significantly alter bowel habits, fecal weight, mean gastrointestinal transit time, or dry matter excretion in healthy young adults over a four-week period, demonstrating that dietary fat alone does not drive overall colonic function changes and suggesting other dietary components mediate cancer-related motility effects.

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 found that eating a high amount of animal fat for a month didn't change how often people went to the bathroom, how heavy their stool was, or how fast food moved through their gut. This means fat alone doesn't change gut movement, so other parts of the diet must be causing those effects.
