Summary
This study from Uppsala University looks at how a low-fat, fiber-rich diet versus a high-fat, Western-style diet affects sleep quality, heart rate, and metabolism. Twenty-four healthy young adults will follow each diet for about a week, then spend two days in the lab for detailed measurements. The goal is to understand how food choices influence our internal body clock and overall health.
