🔥 GI ABSORPTION 101: WHERE NUTRIENTS ACTUALLY GET IN — AND WHAT ANTACIDS STEAL FROM YOU
Your gut isn’t a trash chute. It’s a precision machine. Each section is built to absorb different nutrients…And when you shut off stomach acid with antacids, the whole system gets confused. 🧪 Stomach — The Acid ChamberProtein digestion begins here .Acid “unlocks” minerals so you can absorb them later. Low acid = low: Iron, B12, Calcium, Magnesium, Zinc ⚡ Duodenum — The Mineral Highway Absorbs the minerals the stomach prepped. Blocked upstream? Everything slides by. 🥗 Jejunum — Your Main Grocery Store Where most nutrients enter your bloodstream: Amino acids • Carbs • Fats • Electrolytes • B-vitamins 🎯 Ileum — The B12 Specialist. If you rely on antacids, B12 may never make it to the ileum for absorption. Cue: fatigue, neuropathy, anxiety, brain fog. 🌿 Colon — Microbiome Territory Absorbs water + electrolytes Your microbes make SCFAs (fuel for colon cells), not vitamins. ⚠️ WHY ANTACIDS DERAIL THIS Long-term PPIs/H2 blockers turn off the acid switch →Minerals stay bound → B12 stays stuck → proteins don’t break down → absorption tanks. It’s like shutting down the first tool on an assembly line and wondering why the final product looks defective. ✨ WANT TO UNDERSTAND YOUR GUT?

Why Diets Fail 95% of the Time (and What to Do Instead)
Ever wondered why almost every diet works at first—but then the weight creeps back? It’s not because you’re weak, it’s because your biology is smarter than your willpower. Here’s the science: when you cut calories too hard or too fast, your body thinks you’re in a famine. Within just 3 days of a crash diet, your thyroid hormones can dip, slowing metabolism. At the same time, hunger hormones (ghrelin) spike, basically screaming at your brain: “Feed me, now!” 👉 That’s why white-knuckling your way through extreme diets always backfires. Your body is designed to survive, not to fit into your jeans. AH-HAH Nerdy Fact: The average adult has about 40–50 billion fat cells, and once you lose fat, those cells don’t disappear—they just shrink. And guess what? They “remember” being full. That’s why your body pushes so hard to refill them after weight loss. So the secret isn’t just cutting calories—it’s learning how to keep metabolism, hormones, and satiety signals working with you instead of against you. ✨ That’s exactly what I’m teaching inside my free nutrition course, launching soon—real strategies to get off the diet rollercoaster and move toward sustainable results. Drop one diet myth you grew up believing—let’s see how many we can bust in this thread. TRUE OR FALSE???? GLP1 medications destroy fat cells FOREVER??

One diet myth I grew up with is eating while standing up can burn or won’t put too much calories than sitting down.
