I am creating a plugin that replaces some of the burned food with skinned versions. What I am wanting to do is change the icon of the burned food and change how many calories the player recieves when consuming it.

Is there a way I can change how many calories the player recieves when consuming this food by either modifiying a property on the item or through a hook?

var pizza = ItemManager.CreateByName("bearmeat.burned", 1, 1902068186);
pizza.name = "Pizza";
player.inventory.GiveItem(pizza);​

From looking at the decompiled code you could add or change the elements in ItemModConsumable.effects
