Everyone gets constipated once in a while....these are suggestions how to prevent this from happening (which I myself do):

1. Make sure you have 2-3 cup greens every day (romaine, radichio, etc..)

2. Keep protein at no more than 25% of your daily consumption - too much protein can bind you (and this includes cheese)

3. Drink water! throughout the day - - especially before and after meals!

4. Oil! extra sald dressing or olive oil when preparing meats aids in a "smooth" process.

Watch the nuts too...they are known binders...this includes nut butters.

Hope you feel better soon
