Introduction: Every year, hypertension claims the lives of over 8 million individuals globally and nearly 1.5 million in Southeast Asia.6 In addition to hypertension, chronic diseases experienced by people in Indonesia are Diabetes Mellitus. Diabetes and cardiovascular health are closely related, with diabetes patients having a higher chance of acquiring hypertension and vice versa, creating a potentially harmful synergistic interaction. Newer studies have looked into novel dietary approaches to enhance metabolic health and lower the risk of chronic illnesses. Objective: By shedding light on the intricate relationships between dietary habits, metabolic conditions, and cardiovascular outcomes, this study hopes to advance the development of more specialized and potent treatments for diabetes and hypertension. Method: A prospective cohort study was conducted on participants of PROLANIS Primary Health Care in Tuban from August – September 2023, using One Way Anova and Kruskal Wallis. Results: Mean delta BP patients who had a TRF of 12 hours 11.22±9.804, 6 – 12 hours 13.13±10.341 and did not perform TRF 7.40±8.316, p = 0.309. Mean delta blood glucose patients who had a TRF of 12 hours 14.92±10.09, 6 – 12 hours of 7.30±5.708, and who did not perform TRF of 0.20±4.894, p<0.001 Conclusion: TRF significantly lowers blood glucose in patients with diabetes mellitus, but has not had a significant effect on blood pressure in patients with hypertension.
