Which is more filling?

Chicken breast and pork tenderloin have the same estimated satiety score: 5 out of 5.

  • Chicken breast: Low energy density; a lot of protein per calorie; high water content.
  • Pork tenderloin: Low energy density; a lot of protein per calorie; high water content.

The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.
