Summary
This trial is testing the hypothesis that the time of day for salt intake impacts blood pressure rhythms and urinary sodium excretion in obese individuals.
Who is the study for?
This trial is for obese African Americans aged 25-45 with a BMI of 30-50. It's not suitable for those with drug/alcohol abuse history, high alcohol consumption, pregnancy, hormone therapy use, sleep medication or antidepressant users, kidney disease sufferers, very high blood pressure individuals (>150/90 mmHg), shift workers, sleep disorder patients (like apnea), major chronic diseases like diabetes or severe anemia.
What is being tested?
The study tests if the timing of salt intake affects blood pressure rhythms and urinary sodium excretion in obese people. Participants will limit salt before bedtime to see if it improves day-night blood pressure differences and metabolic risk factors by influencing circadian clock factors linked to renal sodium handling.
What are the potential side effects?
While specific side effects are not listed for oral sodium supplementation in this context, potential risks may include increased blood pressure and related complications due to changes in sodium intake patterns.

Trial Design
2Treatment groups
Experimental Treatment
Group I: Late SodiumExperimental Treatment1 Intervention
Late sodium load: participants will consume a standardized diet providing 2.3 g of sodium per day for 7 days (run-in period), after which they will continue to consume the standardized diet for the next 9 days and in addition will take 2 g of sodium with dinner each day.
Group II: Early SodiumExperimental Treatment1 Intervention
Early sodium load: participants will consume a standardized diet providing 2.3 g of sodium per day for 7 days (run-in period), after which they will continue to consume the standardized diet for 9 days and in addition will take 2 g of sodium in the form of salt tablets with breakfast each day.
