What do you think the health difference between bread and rice is?
Carbs like that should be pretty easy to get calories, especially if you aren’t eating veggies. The big question is, why aren’t you eating fat? Grassfed butter, beef, liver. Coconut, olive, macadamia nut oils. Cheese. Milk.
And add in some veggies if you aren’t eating them.
A lot depends on your goals though.
Something tells me your idea of healthy is pretty terrible if you are talking about product marketing gimmicks.
