Yes. A major factor in promoting whey and other protein supplements, rather than just getting protein in meals, is this idea that they push that you have to get regular pulses of protein in a day, at least a certain amount, and if you don't get the timing just right every day, you've somehow missed out on a muscle building or at least preserving activity. I think it's probably more important just to make sure you get enough on a regular basis, there's not a whole lot of data on taking all your protein in a small number versus a large number of means--one study in older women showed one larger protein meal and then smaller protein feedings, under that threshold we're talking about, as more effective than getting about 20 grams per meal, but that was just the one study.
