According to David Gillespie, artificial and "sugar-free" sweeteners are not the harmless alternatives we've been led to believe they are. Of course you’re not surprised. In fact, they're really sh*t. Scientifically speaking. Apparently, they hijack the brain's expectation of energy, leading to increased hunger and overeating, and may also disrupt gut health and metabolism. More recent compounds - like sugar alcohols and "keto" sweeteners - are framed as potentially more dangerous, with emerging research suggesting links to blood clots and cardiovascular risk. The core message in this episode is that there's no "free lunch" in biology - sweetness without energy comes with consequences. Which is personally very annoying, 'cause I inhale that sh*t. Sorry to disappoint you. I’ll try harder.
