In Part I, we explored how estrogen, insulin, and leptin imbalances can sabotage metabolism and weight loss. Part II picks up with the remaining four hormones: cortisol, thyroid, testosterone, and growth hormone.
Cortisol, the stress hormone, is produced by the adrenal glands and fluctuates throughout the day. When levels run too high or too low, the effects ripple across blood sugar regulation, blood pressure, memory, and energy. Because cortisol is a fat-storage hormone, chronic stimulation — including that daily coffee habit — can contribute to weight gain, insulin resistance, poor sleep, and eventually type 2 diabetes.
Thyroid function is heavily impacted by gluten. Grains spike inflammation, disrupt leptin, thyroid, and insulin levels, and can cause leaky gut or intestinal permeability. Up to 80% of people lack the enzymes needed to properly break down gluten, which can trigger autoimmune conditions like Hashimoto’s Thyroiditis. A Paleo-style diet — rich in fiber, clean proteins, and phytonutrients — aligns well with how our ancestors actually ate.
Testosterone brings us to the topic of toxic burden. Everyday exposure to GM foods, synthetic cosmetics, household chemicals, and BPA (found in plastic bottles, receipts, and canned foods) acts as endocrine disruptors stored in fat cells. These toxins make us insulin and leptin resistant, increase inflammation, and raise the risk of autoimmune disorders and certain cancers. A structured gentle cleanse several times per year can help support the liver’s natural detox function.
Growth Hormone, alongside cortisol, determines how much fat we deposit on our bellies. Conventional dairy is a surprising culprit — it contains casomorphins, opioid-like compounds that are addictive and constipating, plus synthetic growth hormones injected into cows. Switching to almond, coconut, or hemp milk, and trading butter for ghee, are simple steps toward better hormonal balance.
Fixing a broken metabolism isn’t easy — but understanding these seven hormones is a powerful place to start.
