Featured Studies

Dr. Kevin Hall and his team at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) are seeking male volunteers aged 18-65 and female volunteers aged 18-50 for a study on how low-carb (ketogenic) diets, with or without an investigational dietary supplement called Nicotinamide Riboside, impacts energy levels and metabolism during sleep.

Diets worldwide include both processed and unprocessed foods. Researchers at the National Institutes of Health (NIH) in Bethesda, Maryland seek adult volunteers between 18-60 years old to participate in a study examining how processed and unprocessed foods affect metabolic health. Participants will be required to remain at the NIH Clinical Center for one 4-week stay and eat only the foods provided.

Researchers at the National Institutes of Health (NIH) Clinical Center seek healthy women to participate in a research study. Doctors want to learn how the body burns energy at different temperatures. Compensation is provided.

Women diagnosed with polycystic ovary syndrome (PCOS) needed for a research study at the National Institutes of Health (NIH). Researchers want to learn more about how a medication may be used to help your body's insulin work better and if this can improve your overall metabolic health.

Did you know your thyroid gland produces hormones that regulate body temperature, heart rate and metabolism? Physicians want to explore a better method to detect thyroid tumors by using a compound called 68Gallium-DOTATATE. This compound may bind to a tumor and make it visible during a PET/CT scan. This information will help guide future research and treatment.
