Are oats neccesary to be the first carbs of the day?

I ask not because I dislike them, just that heating up some sweet potato would be much quicker and more convenient as I have to wake up pretty early and don't have much time in the morning.

I have 1/2 cup of oats PWO so I am still getting them. I am cutting and only eat carbs at meal 1 and PWO.

No, oats do not have to be the first carbs of the day, it can easily be replaced by another source of complex carb such as sweet potato. Just make sure to calculate macros when you make the switch from oats to yams.
