6 small meals a day is a scam?

Generally protein stays in your system for up to 3 hours (casein 6-8 hours) therefor in order to keep a constant supply of amino acids in your blood you need to eat every 3 hours.

Your information is a bit outdated. See my reply in previous thread regarding the dude eating pizza.

This would indicate over 5 hours for a meal that isn't even that big.

You know who wants you to believe that you only have 3 hours? The people selling protein powder, and the magazines that get income from the protein companies.

Depends on the protein, whey isolate will be out in approximately an hour and a half by design where casein can be up to 8 hours.

Dairy proteins generally take longer (hence cottage cheese before bed as a staple bodybuilding tradition). In that specific example the source of protein was cheese hence the time difference.
Another factor slowing the absorption of protein in this case was the high level of fat.

This will explain the proteins better than I can:

works for me...but that's because I am hungry every 2 hrs..So I eat like every 2 to 3 hours for sanity purposes
