If I had Insulin Resistance AGAIN, This is What I’d do Smarter to Stop it

The speaker bases this protocol on two key studies. The first, a 2021 American Journal of Clinical Nutrition trial, used an LPIR score to show a dose-dependent relationship between carb intake and insulin resistance across 60%, 40%, and 20% carb diets — the lower the carbs, the better the insulin sensitivity. The second, a 2022 JAMA study in 150 pre-diabetics, demonstrated that a structured low-carb approach (<40g net carbs for 3 months, then <60g for 3 months) led to significant reductions in HbA1c, fasting glucose, and body weight, while the usual-diet control group saw no change. He stresses this is not a dogmatic ban on carbs but a necessary 'stop gap' to break the cycle of insulin resistance quickly, giving the pancreas and insulin receptors a chance to reset.

A Cell Metabolism study compared pre-diabetic men eating all meals in a 6-hour window ending by 3 p.m. to a control group eating over a 12-hour window. The early eating group experienced dramatic improvements in insulin sensitivity, beta-cell responsiveness, blood pressure, and oxidative stress — essentially an anti-aging metabolic reset. Insulin levels were markedly lower in every participant except the one with shift-work history, underscoring that the effect depends on circadian alignment. The speaker explains that insulin sensitivity is highest in the morning, so the same carbs eaten at 9 a.m. are processed far more efficiently than at 9 p.m. By front-loading calories, you work with your body's natural rhythm and extend the overnight fast, which further drives down insulin and promotes fat oxidation.

A study in Obesity Research and Clinical Practice found that in normal-weight people, both high-intensity (20 min at 70‑80% HRR) and low-intensity (60 min at 40% HRR) improved insulin resistance. However, in the obese and metabolically unhealthy group, only high-intensity exercise produced a significant improvement. The speaker then explains the underlying biology: muscle contractions during intense exercise activate pathways that cause GLUT4 — the insulin-regulated glucose transporter — to move to the cell membrane independently of insulin. A BMJ study showed HIIT increases GLUT4 content by 260%. This adaptation builds a large pool of transporters that clear glucose from the blood without needing insulin, effectively bypassing the insulin resistance at the muscle level.

The speaker describes an umbrella meta-analysis of 11 large meta-analyses in Diabetology and Metabolic Syndrome that concluded cinnamon significantly reduces fasting glucose, insulin, and insulin resistance. Cinnamon works through three mechanisms: it inhibits digestive enzymes (alpha-amylase, alpha-glucosidase) slowing carb breakdown; it blocks NF-kappa-B, a master inflammatory switch; and cinnamaldehyde directly improves the insulin receptor's sensitivity. TMG (trimethylglycine, also called betaine) acts as a methyl donor, reducing homocysteine and oxidative stress, and helps counter glycation — a process where sugars irreversibly combine with proteins, creating AGEs that damage tissues and fuel insulin resistance. Carnosine is a dipeptide that intercepts reactive carbonyls like methylglyoxal, thereby reducing glycation and AGE formation. He recommends these three as a foundation stack, with the peptide MOTS-c as a more advanced option requiring medical supervision.

The speaker mentions that MOTS-c is naturally occurring in mitochondria and acts as a signaling peptide. A study in Cell Metabolism showed it could prevent age-related and high-fat diet-induced insulin resistance. Its mechanism is to activate AMPK — the cellular energy sensor — in skeletal muscle, which then drives GLUT4 to the membrane to take up glucose, and simultaneously enhances fatty acid oxidation. He says this is the kind of advanced tool he wishes he had known about earlier; he notes it worked well for him, but insists on medical oversight.

The speaker details how the double bonds in industrial polyunsaturated oils are prone to oxidation during processing, heating, and shelf storage. Consumed oxidized oils become part of LDL particles, forming oxidized LDL. A pediatric study linked oxLDL to insulin resistance in children, disproving the notion that this is just an adult problem. OxLDL triggers immune cells to release TNF-alpha, IL-6, and IL-1 beta, which directly interfere with the insulin receptor substrate IRS-1, blocking glucose uptake. It also causes endothelial dysfunction, impairing blood flow and glucose delivery. Therefore, eliminating those oils is step one. For saturated fat, he nuances that short- and medium-chain fats (butyrate in ghee, lauric acid in coconut oil) are anti-inflammatory and improve insulin sensitivity, while excessive long-chain palmitic acid (from junk food) can be dangerous. The star is C15 (pentadecanoic acid), found in goat cheese and certain aged cheeses, which stabilizes cell membranes and enhances insulin receptor function. He recommends a supplement called Fatty 15, which provides synthetic, vegan C15 supported by Navy-funded research.

The speaker walks through a 2021 American Journal of Clinical Nutrition study that split weight-stable individuals into 60%, 40%, and 20% carbohydrate diets and measured insulin resistance via the lipoprotein insulin resistance (LPIR) score — a metric that tracks VLDL, LDL, and HDL particle sizes and concentrations. The result was a linear dose-response: higher carb intake equated to worse insulin resistance. He then escalates to a 2022 JAMA study in 150 pre-diabetics, where a low-carb group (<40g net carbs for 3 months, then <60g for 3 months) saw significant drops in HbA1c, fasting glucose, and body weight, while the control group had zero improvement. His argument is that this isn't just about trimming bread — it's about hitting a low-enough threshold that forces the body to re-sensitize to insulin, and that threshold can be quantified.

He details a landmark Cell Metabolism study with pre-diabetic men. One group ate all meals within a 6-hour window ending by 3 p.m.; the control ate over a standard 12-hour window. The ETRF group saw insulin sensitivity improve 'almost off the charts,' beta-cell responsiveness (the pancreas's ability to secrete insulin appropriately) improved, blood pressure dropped, and oxidative stress markers fell — the equivalent of an anti-aging effect. Insulin levels were radically lower in every participant except one who had a years-long history of overnight shift work, directly implicating circadian rhythm as the mechanism. The speaker explains that morning is when the body is most insulin-sensitive and metabolically active, so carbs at 9 a.m. are handled completely differently than at 9 p.m. Front-loading calories also creates a long overnight fast, giving cells a break from insulin and promoting fat oxidation, further reducing insulin resistance.

A study in Obesity Research and Clinical Practice compared 20 minutes of high-intensity exercise (70‑80% heart rate reserve) to 60 minutes of low-intensity exercise (40% HRR). In normal-weight individuals, both protocols improved insulin resistance nearly equally. But in the obese/metabolically unhealthy group, high-intensity exercise alone drove the improvement. The speaker explains the mechanism: high-intensity interval training (HIIT) massively upregulates GLUT4, the insulin-regulated glucose transporter in muscle. Muscle contractions during intense bouts cause GLUT4 vesicles to travel to the cell membrane without requiring an insulin signal, acting as a 'back door' for glucose uptake. A BMJ study showed that HIIT increases GLUT4 content by 260%. He portrays this as building more 'garage doors' for glucose to leave the blood and enter muscle, directly combating insulin resistance at the source.

The double bonds in polyunsaturated fats like linoleic acid in soybean and corn oil are highly prone to oxidation — especially when heated during processing or cooking, or as they sit on shelves. When ingested, these oxidized lipids become part of LDL particles, making them susceptible to becoming oxidized LDL (oxLDL). He cites a Pediatric Diabetes study that found a direct correlation between oxLDL levels and insulin resistance in children, demonstrating this is not an age-related phenomenon. Mechanistically, oxLDL activates immune cells to release pro-inflammatory cytokines — TNF-alpha, IL-6, IL-1 beta — which then phosphorylate and inhibit a key protein called IRS-1 (insulin receptor substrate), blocking the insulin signal cascade. Additionally, oxLDL causes endothelial dysfunction, reducing blood vessel dilation and thus decreasing glucose delivery to muscle. The takeaway: eliminating these oxidizable oils is a non-negotiable first step. He advises using stable monounsaturated fats (olive, avocado, sesame oil) and appreciating that not all saturated fats are equal — short/medium-chain ones (butyrate from ghee, coconut oil) can be anti-inflammatory, while long-chain palmitic acid from junk food is problematic, especially in combination with high carbs.
