Just how long does it take for whey protein to be absorbed?

[|D_J^B_J|]

I used to use eggs as my protein source at breakfast but got some 'nasty' side effects, so I decided to reduce my intake to one whole egg a day.

This morning I had my usual oatmeal with yoghurt and a piece of fruit but instead of using eggs as a protein source, I used about 30g of whey isolate and one egg.

I'm at uni and I can't fit in a meal until about 2hrs 45mins - 3hrs after breakfast. However, I noticed that after about 2 hours I was rather hungry, which made me wonder whether the protein I ate would have already been entirely absorbed. I would have thought that combined with a low GI carb such as oatmeal and the extra protein and fat form the egg would have slowed the absorption of the whey?

Do you think eating this meal of oats, 1/2 a cup of yoghurt, some berries, 30g of whey and one whole egg would last for about 2hrs 45 mins - 3 hrs and not cause me to become catabolic, or should I use a chicken breast instead?

I'm quite disappointed because I was rather fond of the taste of oatmeal and chocolate protein powder... Oh well.

I understand Whey Isolate gets into the bloodstream within 30 mins, when you drink it alone with water (like in a typical PWO shake).

When you mix it with all that, hard to tell, but since there is nothing to break down it will still much faster than your regular meal. My educated guess is that some 60-90 minutes should be enough (max) for the acids in your stomach to kill all that.
