Dont sweat it, as long as you are meeting your nutrient requirements throughout the day then you will be fine if your dont eat immediately. However it wouldnt be a good idea to go too long without eating.
In the event that you cant face some whole foods straight away, you could always have a serving of whey plus a couple of almonds, then have a whole food meal an hour or so later. Failing that, pop a few BCAAs.
Generally though, you probaby wouldnt want to go too long without some amino acids floating around in you, hence the protein / BCAA recommendations. Its a probably a good idea to keep some aminos in the amino acid pool full as best as possible.
