We’re talking about ghrelin (your hunger hormone), leptin (your fullness hormone), insulin, and the metabolic trap so many people are stuck in today.You’ll learn why sugar spikes don’t just affect your waistline—they disrupt hormonal communication, shut down fat burning, intensify cravings, and keep you riding a glucose roller coaster all day long. And most importantly, you’ll understand why this isn’t a willpower issue or a personal failure—it’s physiology.In this episode, Krista explains:Why sugar increases hunger instead of satisfactionHow ghrelin surges during blood sugar crashesWhy leptin resistance leaves you feeling “full but not satisfied”How insulin blocks fat burning—even when you’re eating less or exercisingWhat a sugar crash actually is and why it triggers intense cravingsHow GLUT4 works and why movement is one of the most powerful metabolic tools you haveThis conversation is deep, eye-opening, and designed to give you clarity without shame. Once you understand what’s happening beneath the surface, you can stop fighting your body and start working with it.If sugar, cravings, stubborn weight gain, energy crashes, or feeling out of control around food has been a lifelong battle, this episode will help you connect the dots—and remind you that nothing is wrong with you.✨ Stay tuned, because in the next episode of the Sugar Series, Krista breaks down fruit, sweeteners, and the myths around “healthy sugars”—including honey, stevia, monk fruit, sugar alcohols, and why whole fruit behaves very differently than fruit juice.
