It’s difficult to image 20,000 calories of food but it’s about the same as 20 full English breakfasts

 

Big animals come with big appetites. To survive, a grizzly bear has to eat 20,000 calories a day. In a more human context, this equates to around 20 full English breakfasts every day. Bears mostly live on a diet of nuts, berries, carrion and some fish when they can find it. These foods are all much lower in calories than our greasy breakfasts, so the search for their next snack never ends.
