Are Mood Disorders Actually Metabolic Diseases Rooted in Insulin Resistance?
It appears that the can of worms is fully opening……
Truth-telling doctors have completely upended the cancer paradigm by stating it’s a metabolic disease. Now, research is showing it’s also behind mood disorders like bipolar and depression as well. This is good news for those who suffer with these often treatment resistant diseases because you can fully change your metabolism, which means you could finally be free from these plagues.
Are Mood Disorders Actually Metabolic Diseases Rooted in Insulin Resistance?
November 03, 2025

Story at-a-glance
- Bipolar disorder and depression affect tens of millions globally, long treated as strictly brain-based illnesses, yet both consistently show high rates of insulin resistance and metabolic disturbances
- A 2025 Nature Neuroscience study found that pancreatic insulin release and hippocampal activity are linked through a circadian feedback loop. This suggests bipolar mood shifts arise from disrupted metabolism, not brain chemistry alone
- Earlier research in 2022 showed lithium stabilizes mood partly by restoring insulin signaling, while a clinical trial found metformin improved both insulin sensitivity and psychiatric symptoms in treatment-resistant bipolar depression patients
- Insulin resistance is extremely widespread, with around 40% of Americans affected, driven by refined sugars, seed oils, stress, sleep loss, and environmental exposures that disrupt the body’s natural energy regulation
- Supporting insulin sensitivity involves stepwise changes, replacing damaging fats and ultraprocessed foods, introducing gut-friendly carbs and fibers gradually, managing stress, improving sleep, and staying active to stabilize both metabolic and mental health (See link for article)

The Importance of Testing
One of the most straightforward ways to gauge how well your body responds to insulin is through a test called HOMA-IR, short for Homeostatic Model Assessment of Insulin Resistance. It requires only two basic blood tests, both done first thing in the morning before you eat. One test measures fasting glucose and the other measures fasting insulin.
Once you have those two numbers, they are entered into a simple formula:
HOMA-IR = (Fasting Glucose in mg/dL × Fasting Insulin in μU/mL) ÷ 405
This score shows how hard your body is working to keep blood sugar in check — A higher number means your pancreas is pushing out more insulin to control your glucose levels, which signals that your cells are becoming resistant to insulin’s effect. Ideally, your HOMA-IR should be under 1.0. Even values around 1.0 deserve attention, because they show that your body may already be moving toward resistance. The lower the number, the better your insulin sensitivity.
The ability to track your progress over time makes HOMA-IR even more valuable. As you make adjustments in diet, movement, and lifestyle, you can retest and see whether your score is improving. That direct feedback provides motivation and clarity, showing you how your efforts translate into measurable improvements in insulin sensitivity and, by extension, in your long-term health.
Steps to Improve Insulin Sensitivity
- Start with carbs that are easy on your gut — Glucose is often automatically viewed as harmful in the context of insulin resistance, yet your body relies on it as a primary fuel. If you cut carbs too low, your body compensates by raising cortisol, a stress hormone that breaks down muscle tissue to make glucose, which weakens your metabolic health over time. Most adults require about 250 grams of healthy carbohydrates a day.
- Introduce resistant starches and root vegetables once stable — When your system has stabilized, resistant starches and root vegetables can be introduced in small amounts. Cooked and cooled white potatoes or green bananas are two reliable starting points, then you can expand to foods like garlic, onions, and leeks, which nourish the bacteria that produce butyrate, a short-chain fatty acid that strengthens your gut lining and supports blood sugar regulation. This is often the stage where people notice steadier energy, fewer cravings, and more balanced glucose levels.
- As your digestion becomes more resilient, you can slowly rotate in a wider variety of plant foods — Begin with root vegetables, then move toward leafy greens, beans, legumes, and eventually whole grains. The key is to add them gradually and not to eat the same new food every day at the start. Your gut bacteria need time to adjust to new fiber sources, and pacing yourself helps avoid the discomfort that can come with sudden changes.
- Alongside what you add, it is equally important to cut out what damages your gut — Vegetable oils high in linoleic acid, ultraprocessed foods, and alcohol all erode the gut barrier and encourage the growth of bacteria that worsen inflammation and insulin resistance. Replacing these with healthier fats such as grass fed butter, ghee, or tallow helps repair the intestinal lining and supports the balance of your microbiome. A healthier gut environment, in turn, makes your cells more responsive to insulin.




In her groundbreaking book, Bitten: The Secret History of Lyme Disease and Biological Weapons, science journalist Kris Newby details how US biowarfare research programs, including work at the Rocky Mountain Laboratories in Hamilton, Montana, experimented with spirochetes to alter virulence and transmission. The intention of these manipulations, although unclear, likely spawned Borrelia burgdorferi, the stealth pathogen now linked to millions of chronic infections worldwide. The same recombinant DNA methods used in agricultural GMOs were being applied in microbial genetics at the time.
