July 14, 2025 Ep. 232 10 Reasons to Test Your Gut if You Want to Lose Weight

If you’re eating clean, working out, and still not losing weight… your gut might be the missing piece.

In today’s episode, I’m breaking down 10 reasons why gut health directly impacts your metabolism, hormones, and ability to lose fat and why testing with a GI MAP could be the game-changer you’ve been missing.

We’ll talk about how certain gut infections like H. pylori or parasites keep your body in survival mode, signaling it to hold on to fat. You’ll learn how your gut bacteria influence your cravings, blood sugar, and even your metabolism through short-chain fatty acids like butyrate.

I’ll explain why hidden gut inflammation can block fat loss and how slow digestion (aka not pooping daily) recirculates estrogen and toxins, stalling your progress.

We’ll also dive into how bad bacteria can steal essential nutrients you need for fat-burning, how gut health affects your thyroid function, and why your gut impacts not just your body, but your brain chemistry and motivation too.

Plus, I’ll explain why detoxing estrogen properly is key to shedding stubborn fat and how even the “perfect” diet won’t work if your gut can’t break down food and eliminate waste.

This episode will help you see why your gut is the foundation of sustainable weight loss and why it’s not just about willpower or cutting calories.

If you’re feeling stuck, testing your gut might be the missing link to get your body working with you again.
