I can't eat as much as i want to!

[Austex]

I highly suggest you not only consume water for a day (if thats what Aust meant by this)

That is what I meant. Think about it...Putting on muscle involves a number of key ingredients:

1. Weight Training (Muscle Break-down)
2. Eating (Consistently)
3. Drinking Plenty of Water (Hydration for Healthy Organ Function, Protein Synthesis)
3. SLEEP (Muscle Repair)

BUT, there is a limit to which these variables can exceed. When that time comes, the best remedy is either:

1. Take time off.
or
2. Put your body in shock by means other than resistance training.

If you continue to drive yourself 100% all the time, your body adapts to this and it is no longer "change". The greatest way to accomplish goals is to not let the body adapt. Every (ex.) 3 months, change things up a bit.

Now, he claims to be eating this way for 2 years. The first thing that goes through my mind is that his body has adapted to this diet. He also claims that his PPWO seems to be the hardest to consume. This also tells me that there is a possibility that his metabolism is slower, not digesting all of the PWO shake <or> his cortisol levels are remaining elevated pwo, and his appetite is lost because of it.

My remedy for this is to shock the body with a change. A change in diet, times that meals are consumed, or as I suggested earlier, fasting. It does work.

I always like to provide evidence for those in doubt...

Likely due to the increased physical and psychological stresses associated with these conditions, persons suffering from depression, anxiety, panic disorder, malnutrition and alcohol abuse also often have elevated cortisol values.

Touche, informative links, still stand by my statement though but I do understand your point.
