This study monitored 20 adult male Sprague-Dawley rats after 24-hour food deprivation before four trials with Froot Loops. Results showed the slower the rat ate, the less it consumed. Three rats notably ate slower. Data included meal duration, Froot Loops consumption, and consumption rate.

  1. Results from Unrestricted Intake Experiments • N= 20 Adult male Sprague-Dawley rats • Food deprivation 24 hours prior to each of the 4 trials conducted at one week intervals during the 1st hour of Lights On. • Provided Froot Loops one at a time until rat terminates meal (defined as not consuming for 10 minutes) • Measurements • Time to consume each Froot Loop (sec) (data not shown) • Meal duration in seconds • Number of Froot Loops consumed • Grams of Froot Loops consumed • Rate of Froot Loop consumption (sec/FL)

  6. Conclusion: The slower a rat eats, the less it consumes or said in another way “The faster a rat eats, the more it consumes.” Caution: Three rats consistently tend to eat dramatically slower than the other eighteen.
