I am a board certified internist practicing in Chicago. A primary focus of my practice is the prevention of prediabetes/diabetes progression through paleo focused dietary choices. I give a lecture for the public on this topic at noon the first saturday of every month at 2pm at my practice address listed below which anyone is welcome to attend. The first half focuses on the decline of a human pancreas resulting in prediabetes/diabetes (most recent statistics say this is now 52% of americans!). The second half focuses on the reasons we gain (or lose) weight, the hormones involved with the regulation of fat, and why it is so difficult to lose weight with the dietary choices many of us make regardless of how little we eat because of the effect these choices have on body/brain hormones.
