Believe it or not, there’s an official scale for measuring the filling effect of foods! It’s called the satiety index. According to the official rankings of over 100 different listings, filling foods tend to have the following characteristics: 

  • High in protein 
  • High in volume
  • Low in energy density 

Studies have shown that protein is the most filling macronutrient, meaning healthy protein snacks are one of the best options if you’re looking to fill up. Whilst the snacking landscape is ever-evolving, one snack has remained a firm favourite with the public for at-home snacking, travelling, quick power-ups, and even events – beef jerky.
