Time to look at what foods you may be allergic to. Dairy, artificial sweeteners, processed sugar and gluten to name a few. Test by completely eliminating each in turn and keep record of your waist measurement (morning just after BM) for a least a month. For me it is dairy. If I eat ice cream or yogurt I'll see an inch added to my wast by the next morning. Also, add in a good probiotic to your daily.
