This Ends Insulin Resistance (in days NOT years)

DeLauer uses the garage door analogy. Insulin is the remote control, but when DAG sludge jams the receiver, the door won't open. Exercise is the manual override. Walking for 15–20 minutes after eating forces GLUT4 transporters to the cell surface independent of insulin, shunting blood glucose into muscle, reducing the sugar load that would otherwise cause glycation and further fat storage. He emphasizes this is simple but profoundly effective, because it turns the body's own contraction-mediated pathway into a tool that directly combats post-meal glucose spikes. This habit also initiates a virtuous cycle: with less glucose hanging around, less insulin is needed over time, and the pancreas gets a rest. Over weeks, combined with other strategies, insulin sensitivity can be restored. He notes that many people experience a heavy crash after meals, and this walk can help prevent that.

DeLauer explains that when muscles are contracting, the GLUT4 doors are already wide open via AMPK. Adding a small amount of fast carbs at that precise time provides a targeted fuel source that goes directly into the muscle cells being worked, bypassing the jammed insulin signal. This not only prevents the carbs from spilling into fat storage or contributing to glycation, but also gives the person the energy to train harder, building more muscle. More muscle improves overall metabolic rate and insulin sensitivity long-term. He frames it as 'force-feeding' your muscles for a better workout while the rest of the body stays insulin-sensitive. It's a tactical use of carbs that flips the script—using the very nutrient that normally causes problems to instead enhance recovery and metabolic repair.

Building on the fat gas tank theory, DeLauer explains that if your tank is small, even normal meals can cause a rapid influx of energy that overflows into the bloodstream as fatty acids. By adding protein and soluble fiber, you physically slow the rate at which energy enters the system, preventing the adipocyte spillover that creates DAG sludge. He gives personal examples of mixing psyllium into cottage cheese or yogurt with a bit of whey protein and monk fruit. He emphasizes it's not just about gut health, but about controlling the kinetics of nutrient absorption to protect insulin signaling. This tactic lets you enjoy a meal while keeping the metabolic flood at bay, thus preserving insulin sensitivity. Combined with a post-meal walk, it's a powerful one-two punch.

DeLauer draws an analogy: if DAG sludge has built up in the muscle, you need an industrial-strength vacuum cleaner. TMG acts like that vacuum by improving mitochondrial efficiency—the cellular power plants that burn fat. When mitochondria are functioning better, they can take up the excess fatty acids and oxidize them for ATP, preventing their conversion into DAG. Additionally, TMG activates the AMPK pathway, which we know is the same pathway that exercise uses to open GLUT4 doors. This dual action both cleans up existing sludge and prevents new sludge from forming. He says it helped him when he felt that his metabolism was fundamentally broken, and it can be a useful tool alongside diet and exercise.

DeLauer describes the experience of seeing his own blood test with high insulin and feeling frustrated that his body was ignoring the signal. He researched insulin sensitizers and found that cinnamon, particularly the Saigon variety, has strong evidence for improving insulin signaling. The compounds mimic insulin's action not by replacing it but by helping the rusty lock work better, making the existing insulin more effective. He suggests it as a simple spice addition that can be integrated into daily meals. This is a gentle, side-effect-free tool that complements the other strategies such as exercise and fasting.

DeLauer presents fasting as the 'master reset button' because it directly addresses overnutrition at its core: by completely stopping the influx of nutrients, you break the chronic fatty acid flood. He explains that during fasting, the body lowers insulin, increases glucagon, and switches to fat burning. AMPK and autophagy are upregulated, and the autophagy process literally consumes the DAG-laden lipid droplets and dysfunctional mitochondria, something other strategies can't do as profoundly. He contrasts this with his own failed attempts at eating six small meals a day or just cutting calories—those kept insulin and fatty acid flux modestly high. Fasting created a true low-insulin window that allowed his cells to recover. He notes that even a simple 16:8 pattern can begin reversing years of damage by giving the body the uninterrupted healing time it needs. He also links this back to the evolutionary insulin resistance program: fasting corrects the false starvation signal.

DeLauer explains that when glucose piles up in the bloodstream due to insulin resistance, it drives a chemical reaction called glycation—sticky sugar molecules bind to proteins, causing them to become stiff and dysfunctional. This process accelerates aging, damages blood vessels, kidneys, and collagen, and contributes to cardiovascular disease. Carnosine intervenes by getting itself glycated instead, sparing the body's proteins. He likens it to a sacrificial shield. He says it's a 'quick hit' you can add alongside the other strategies to reduce collateral damage while you work on reversing the root cause. He recommends 3–6 grams, which is a fairly high but standard supplement dose, and suggests it with high-carb meals to blunt the postprandial glycation burst. Combined with exercise and fiber, it gives added protection.

DeLauer cites a study in the Journal of Clinical Endocrinology & Metabolism on adults 18–44. The findings show that insulin resistance is rampant even in lean individuals, a ‘thin outside fat inside’ (TOFI) phenomenon. He emphasizes that because the pancreas works overtime to keep glucose normal, the typical lab test is misleading. The real damage—glycation, cardiovascular disease, brain fog, and spongy abdominal fat—is already underway. He points out that insulin resistance is a more powerful predictor of cardiovascular disease than LDL, underscoring the urgency of screening fasting insulin and post-meal glucose, not just fasting glucose.

DeLauer describes work by Dr. Gerald Schulman at Yale (published in Physiological Reviews) identifying DAG as a sludge-like metabolite. When adipocytes reach their storage limit, they release free fatty acids that infiltrate muscle and are converted to DAG. This DAG interferes with insulin's signal cascade, preventing GLUT4 transporters from moving to the cell surface—the 'garage door' won't open. He emphasizes that this is driven by 'overnutrition' generally, not just sugar. The DAG mechanism explains why lean individuals with small fat storage capacity can quickly become insulin resistant, and why cutting only carbs may not suffice.

DeLauer explains that during a true fast, fatty acids are released, which transiently blunts muscle glucose uptake to preserve glucose for the brain. This is beneficial. However, when someone overeats constantly, the same fatty acid flood occurs, tricking the body into thinking it's starving and triggering perpetual IR. The muscles stay resistant, and the pancreas pumps out more insulin. Fasting, by contrast, lets the body clear the flood and resets the metabolic signals. This insight shows why purely calorie restriction with frequent meals may fail—it never breaks the fatty acid flux pattern. The key is providing an extended low-insulin window through time-restricted feeding.

DeLauer describes the 'fat gas tank theory.' Some people have huge subcutaneous storage capacity, so they can absorb excess calories without rapid spillover into the bloodstream. Others have a small tank; even a slight surplus causes fatty acids to leak, forming DAG in muscle and driving IR. This explains the lean but insulin-resistant phenotype (TOFI). He says this can feel discouraging, but it's empowering because it clarifies the need to never let the tank get full—by slowing nutrient entry with fiber and protein, and by maintaining a small energy deficit when needed.
