How Poor Sleep Sabotages Your Diet & Metabolism

In this episode of the Diet Doctor podcast, we dive deep into one of the most overlooked aspects of health—sleep. We explore how your diet, hormones, and lifestyle choices directly impact sleep quality and why poor sleep can lead to metabolic disorders, weight gain, and even chronic diseases.

We discuss the circadian rhythm, the hormonal effects of sleep deprivation (ghrelin, leptin, and insulin resistance), and how a lack of sleep increases cravings for high-calorie foods. Plus, we break down why quality matters more than quantity when it comes to sleep, and how simple lifestyle adjustments—like food choices, light exposure, and even naps—can radically improve sleep quality.

If you've ever struggled with low energy, poor recovery, or weight issues, this episode will provide practical, science-backed strategies to optimise your sleep and overall health.
