I switched oils and eating felt easier.
No cleanse, no rigid rules. I moved to olive oil, avocado oil, and high-oleic versions for cooking. Pulled back on deep-fried takeout and restaurant meals where seed oils dominate every dish.
Within a few weeks I noticed my hunger wasn't this constant background noise anymore.
Energy felt steadier through the afternoon instead of that 3pm crash. The plan was easy to keep because I wasn't fighting my body the whole time.
After 15 years in functional health, I've watched this play out with thousands of patients who make the same switch.
Here's the mechanism that matters:
Polyunsaturated fatty acids in seed oils (soybean, canola, corn) oxidize easily when exposed to heat, air, or just sitting in your tissues. Those oxidized compounds create inflammatory metabolites that interfere with hunger signaling and metabolic function at the cellular level.
Linoleic acid has a half-life of about two years in your body. That means the damage builds meal after meal, and getting rid of stored oxidized fats takes years... not weeks.
Between 1909 and 1999, soybean oil consumption increased over 1000% in America. We replaced butter, lard, and tallow with highly processed vegetable oils. The food industry called it progress.
But what I see in patient labs tells a different story.
When people eliminate processed seed oils and return to stable fats like olive oil, butter, ghee, and tallow, inflammatory markers improve. Hormone panels shift. And most importantly, they tell me eating feels simpler and hunger feels manageable for the first time in years.
Your body responds to the environment you give it.
Seed oils create oxidative stress and inflammatory static that makes everything harder. More stable fats reduce that load so your cells can actually function the way they're designed to.
The fix is simpler than most people think, but it takes time because of how long these compounds stick around in tissues.
What are you cooking with right now? Comment "olive oil" if you've already made the switch, or "curious" if you're thinking about it.
