The goal of a diet should be health. It something causes you to lose weight it should not be deemed healthy for that reason only. While it's healthy to be at an acceptable weight, it needs to be done in the right way.
I'm extremely skeptical of any diet that recommends limiting the intake of fruit, considering the overwhelming amount of evidence that shows how healthy fruit is for us. I do agree that cereals/breads/etc are complete trash, though. They're basically empty calories.
If you're interesting in reading about a variation of the approach you recommended--where fruits/veggies are encouraged in unlimited quantities with breads/cereals/etc are discouraged due to low nutrient density, I'd recommend "Eat to Live" by Joel Fuhrman (
