Can eating too much of a healthy food still be fattening?

Like we made these healthy muffins that have blueberry's and lots of protein. And they have no butter or anything like that. they are made with whole grain, and i had like four of them lol. They aren't huge muffins though...
The sweetness comes from honey. i don't think that much though.
im already healty. i watch what i eat.

i wanna get ripped.
