Grizzly bears eat 20,000 calories a day
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.
