How Cortisol and Insulin Drive Cravings

In this episode, Sherry breaks down one of the most misunderstood reasons weight release feels impossible — and it has nothing to do with willpower, discipline, or “doing it wrong.” It’s all about your nervous system, hormones, and how your body is trying to protect you.1. The Autonomic Nervous System: Your Body’s Survival Command CenterSherry revisits the autonomic nervous system — the unconscious system running everything behind the scenes: thoughts, emotions, behavior, hormones, digestion, metabolism.When life feels overwhelming or unsafe, this system shifts into protection mode (fight-or-flight, sympathetic state). This state isn’t bad or broken — it’s brilliant, designed to help you survive real danger. The problem? It was meant to last minutes or hours, not weeks, months, or years.2. Why Protection Mode Slows MetabolismWhen your body senses danger, survival comes first, not weight release. It adapts by slowing metabolism, conserving energy, increasing cravings, and prioritizing fat storage.If you struggle with constant hunger, sugar cravings, binge eating, or dopamine-seeking behaviors, remember: your body is not failing — it’s doing exactly what it was designed to do.3. Cortisol: The “Keep You Alive” HormoneCortisol, released from the adrenal glands in protection mode, keeps blood sugar available, provides instant energy, and ensures survival.Cortisol pulls glucose into the bloodstream, increases cravings for quick energy, triggers binge responses, and makes you feel like a bottomless pit. In modern life, we stress, sit, and scroll instead of running or climbing. That unused blood sugar circulates, creating hormonal consequences.4. Insulin: The Storage HormoneWhen blood sugar stays high, insulin steps in to store glucose as glycogen, protect tissues, and convert excess sugar into body fat once storage is full.When insulin is high, your body cannot access stored fat. This is why weight release stalls and dieting feels futile. Repeated cortisol + insulin spikes can lead to insulin resistance, pre-diabetes, PCOS, hypothyroid symptoms, or adrenal fatigue. Sherry reminds us: these conditions are results, not starting points.5. Why Dieting Doesn’t Fix the Root ProblemTrying to “just stop sugar” while cortisol is high is like trying to stop your body from healing a cut. Logic cannot override biology. Elevated cortisol keeps cravings, binge urges, and food obsession active. That’s why Make Peace With Food starts with regulating the nervous system, not controlling food.6. Scarcity Mindset = Protection ModeScarcity mindset is protection mode. Any “not enough” thought — not enough time, sleep, money, progress, worth — keeps cortisol elevated. Success doesn’t eliminate scarcity because it’s fear-based. Fear biologically signals danger.7. Fear Creates ChemistryEvery thought creates chemistry: Scarcity → fear → protection mode → cortisol → cravings + storage. This is why people can know what to do, want change, yet still feel stuck. Biology always overrides willpower.TakeawaysYour body is protective, not failing.Cortisol and insulin are survival hormones.Chronic stress locks the body into storage mode.Dieting cannot fix a dysregulated nervous system.Scarcity mindset keeps you in protection mode.Journal PromptsWhere do I live in “not enough”?What fears keep my body in protection mode?How does my body protect me through food?What would safety feel like in my body today?What small shift could move me from scarcity to trust?Listen to more episodes at makepeacewithfood.com/podcast or subscribe on Spotify, Apple Podcast, and YouTube.Listen to more episodes at www.makepeacewithfood.com/podcast or subscribe to me on Spotify, Podcast, and YouTube so you never miss an episode!Join my Facebook Community: www.myfoodfreedomlifestyle.com Work with me: www.sherryshaban.com/transform Go deeper: www.makepeacewithfood.com Share your biggest takeaway and tag me on Instagram, Facebook, TikTok, LinkedIn
