The purpose of this research study is to learn about time restricted feeding and breast cancer risk markers in post-menopausal women with prediabetes. Time restricted feeding involves changing the daily eating period for consumption of meals and snacks.
Participants will be randomly assigned to either the time restricted feeding group with a daily eating period of 8 hours or the control group with a daily eating period of greater than or equal to 12 hours. There are 2 in-person study visits to have blood, urine and vital signs collected, 1 remote or phone visit with study coordinator and 8 remote or phone visits with a psychologist or dietician to assist with the eating schedule . The study will take about 3 1/2 months. There is no cost to participate. Compensation for the 2 in-person visits is provided..
Heart disease can be detected in the hospital by Cardiac Magnetic Resonance (CMR)- a device that uses a large magnet. CMR is used to test how healthy the heart muscle is and how well the heart is pumping. We will test a new method to see how helpful it is to quickly get good pictures and if this is useful for testing the health of heart muscle in patients with heart disease.
