Be careful about making your coffee 'bulletproof', dietitians say

Dietitians are offering a word of warning when it comes to 'bulletproof' coffee.

The current diet trend is a blend of butter and coconut oil in your cup of joe.

No danger in drinking 4-5 cups of coffee per day.

Supporters say this high-fat coffee is an energy boost.

But dietitians warn you're taking that coffee from 0 calories to almost 500.

Instead, they recommend balancing your java with fresh fruits or oatmeal for a similar energy kick.
