My meals consist of a costco rotisserie chicken breast and 3 cups of raw broccoli. It takes me 20 minutes to eat as I have very little appetite but I'm able to eat what my body needs as long I can convince myself it does. If I can't choke down enough raw broc, I add some psyllium husk that night.
I find this particular, very specific meal provides enough fat and fiber that I'm not crappin' gravel the next day.
Adding in lifting and cardio every week can dry me up, but taking supplements like calcium, iron, b-complex multivitamin w/electrolytes, and doing a decent job keeping up on sugar-free gatorade and water has prevented even a single clogged chute since I started almost 2 months ago.
