How to change the base hunger rate?

I found "FoodStats.java" that contains the code of how the food level is decreased, is any way of changing that function?

public void tick(PlayerEntity player) {
      Difficulty difficulty = player.world.getDifficulty();
      this.prevFoodLevel = this.foodLevel;
      if (this.foodExhaustionLevel > 4.0F) {
         this.foodExhaustionLevel -= 4.0F;
         if (this.foodSaturationLevel > 0.0F) {
            this.foodSaturationLevel = Math.max(this.foodSaturationLevel - 1.0F, 0.0F);
         } else if (difficulty != Difficulty.PEACEFUL) {
            this.foodLevel = Math.max(this.foodLevel - 1, 0);
         }
      }
