Try drinking more water. Your hunger pains and shakiness can be signs of dehydration. You might try adding an electrolyte to your water. Vitalyte is a good option. You can read about it at www.vitalyte.com
Just because you lost your colon DOES NOT MEAN YOU WILL LOSE WEIGHT!!! Remember, the colon is only an organ to hold waste. Even though your frequency is higher it does not mean that you will lose weight. This is a common misconception about colectomies.
To lose weight you need to decrease calories and increase exercise. A sound way to do this is by following weight watchers. You can do that diet online and never go to a meeting. There is no secret. Exercise is needed to kick up the metabolism. Choose from healthy low calorie snacks and don't make excuses. I have lost 25lbs this way. It can work and safely at 1-2lbs per week.
At this point you should be able to exercise in the form of walking. My surgeon had us walking one mile before we were allowed to leave the hospital! It was marked in the halls. I credit my recovery to my surgeon's belief that exercise is vital for recovery.
