I don't have the familiar stuffed gut. After meals where I previously mixed carbs, proteins, fruits and veggies I could go the rest of the day not eating another thing and still feel full. Reason: I believe all the food just sat in my gut, while my stomach tried to figure out what to do with all of it. Should it make acid or alkaline juices? Hmm! Should the pancreas send out protease and lipase enzymes to break down the proteins and fats or amylase for carbs?
Literally after the first day of correct combining, I began to get hungry after 2-3 hours of eating. The real eye opener was waking during the night and feeling very hungry. By morning I was famished and my stomach was flatter than normal. I forgot how good it feels to feel hungry.

My explanation for this is, by allowing my stomach, pancreas clear understanding (by foods combining) of what they needed to provide to churn the food into nutrients I could use, the job was done well and with efficiency. Moving along the track it ran into the backend of a lot of stagnant, not so well digested meals previously eaten. Like a caboose pushing a train, the well digested foods pushes the old, half digested sludge on through. When the sludge comes to it's final destination, elimination, they STUNK.
I guess I tell you this because IF you have Really stinky poo's a few times a week, you're probably have digestion problems and have foods left undigested and rotting in your gut.
So at the end of 6 weeks I've lost approximately 8.5 pounds. I'm happy with that. I feel better because of eating better. My digestion is 90% better. I know immediately when I've eaten something I shouldn't. I also know pretty quick when I eat the wrong foods together.
