How daylight affects your weight and metabolism – with Dr Sara Pugh

Struggling to lose weight despite eating well and exercising? Biochemist Dr Sara Pugh joins Liz to explain why the answer may not just lie in what's on your plate – but in how much natural daylight you're getting.

They discuss how leptin, the appetite-regulating hormone, follows our circadian rhythm and the link between light exposure, satiety and weight gain.

Sara also talks about the effects of screen time and artificial light on metabolism and shares ways to reconnect your body with natural light cues.

In this episode:

·     The importance of early-morning daylight for mood and metabolism

·     Why artificial lighting after dark disrupts fat-burning

·     How light exposure regulates our hunger hormones

·     The surprising impact of late-night scrolling on your weight

·     Why eating within daylight hours keeps hunger signals balanced
