Why You’re Doing Everything Right… But Still Not Losing Weight

Have you ever felt like your body is working against you?


You’re eating clean, getting your steps in, managing stress as best you can—but the scale won’t budge. And worse? Your energy is tanking, your joints ache, and your clothes feel tighter even though your habits haven’t changed.

You’re not crazy. You’re not broken. You might just be dealing with something called obesogens.


What Are Obesogens?


Obesogens are a class of environmental toxins that disrupt your hormones, metabolism, and how your body stores fat.

Unlike calories or macros, obesogens don’t come from food—they come from things like:

  • BPA, found in plastic containers and thermal receipts

  • Phthalates, hiding in fragranced products

  • Pesticides, on non-organic produce

  • Heavy metals and PFAS (those “forever chemicals”)

Even in tiny amounts, these chemicals can confuse your endocrine system, especially if your detox pathways are sluggish (a common issue in perimenopause and autoimmune flare-ups).


How Obesogens Hijack Your Metabolism


Your metabolism isn’t just about calories in, calories out. It’s a symphony of hormones—thyroid, insulin, cortisol, estrogen—all working together. Obesogens can throw that delicate balance out of tune by:


🔁 Disrupting appetite and satiety signals (making you feel hungrier or crave sugar)

📉 Slowing your thyroid (your metabolism's engine)

📦 Promoting fat storage, especially around the belly

⚖️ Worsening insulin resistance, which makes it harder to burn fat and easier to gain it


The BPA Problem: A Closer Look


BPA (bisphenol A) is one of the most common—and most researched—obesogens. It mimics estrogen, binding to your hormone receptors and throwing off your natural rhythm.


This is especially problematic in perimenopause, when estrogen levels are fluctuating wildly. Add BPA to the mix, and your body may respond by:

  • Holding on to fat (especially visceral fat)

  • Experiencing more bloating and inflammation

  • Feeling fatigued despite good sleep and nutrition

  • Struggling with symptoms like brain fog, mood swings, or joint pain


Why It’s Worse During Perimenopause

If you’re in your late 30s, 40s, or early 50s, you’re already riding the hormone roller coaster. Obesogens amplify that chaos, contributing to:


  • Estrogen dominance

  • Thyroid dysfunction

  • Slower detoxification

  • More intense autoimmune flare-ups

It’s like trying to balance on one foot while someone throws marbles at you—it’s not impossible, but it’s way harder when you're under toxic stress.


What You Can Do Right Now

Here’s the good news: You don’t need to be perfect—you just need to start where you are.


🌿 Ditch plastics: Use glass or stainless steel for water and food storage

🧾 Say no to receipts: Opt for digital whenever you can

🧴 Go fragrance-free: Choose clean skincare, makeup, and home products

🥗 Eat organic when possible: Especially for high-pesticide foods like strawberries and spinach

🛁 Support detox pathways: Think minerals (like magnesium + sodium), gentle binders, sweating, and nourishing your gut.



These shifts might seem small—but they compound over time. And for many women I work with, clearing these toxic blocks is the missing link to feeling like themselves again.
