A single group feasibility study published in the Journal of the American College of Cardiology: Cardiac Onco showed a 15% decline in CVD risk among breast cancer survivors (BCS) after following 8 weeks of a time-restricted eating regimen. Amy A. Kirkham, Ph.D., assistant professor of kinesiology and physical education, University of Toronto stated that time-restricted eating decreased visceral adipose tissue which was previously reported to have a rapid accumulation rate among BCS causing cardiac events.

She also added that the time-restricted approach is easier for patients to follow due to a scheduled start or end time to eat. This is also easier for doctors to prescribe and explain than brainstorming ways to meet the physical activity guidelines each week. The study included 22 participants with a mean age of 66 years and a mean BMI in the range of 31 ± 5 kg/m². The subjects were allowed to eat freely between 12 PM and 8 PM on weekdays and anytime on weekends. Outside the allocated time, they can only drink black coffee, water, or black tea.

The result showed that after 8 weeks the median CVD risk decreased from 10.9% to 8.6%. Also, the calorie intake was decreased by 450 Kcal i.e., a reduction of 22% from the base value. The reported data also showed that the whole-body fat, body mass, MRI-derived VAT, etc were decreased from the median value. Furthermore, after the intervention, 53% of the subjects were no longer classified as high-risk patients for CVD outcomes.
