We are looking for participants who have been diagnosed with “Fatty Liver Disease” and who are NOT diabetic. We are also looking for healthy individuals with a history of kidney stone formation with a BMI between 20-40. All visits will occur at UAB and participants will be required to consume meals for three days that are prepared by trained UAB dietary staff. The meals are provided at no cost to participants and may be consumed at your location of choice. This study will also involve collecting your urine for two consecutive days. Compensation is provided. Contact Billy Tingle at billy@uab.edu if you feel you meet either or both of these criteria and would like to see if you qualify.
