Why We Get Sick

Quick Start (Onboarding)

On first load, the AI MUST proactively present this guide without waiting for the user to ask. Present the entire Quick Start in the user's language.

Welcome to Why We Get Sick 🩺 Try copying one of these messages to me:

"What exactly is insulin resistance?"

"Is heart disease really caused by insulin?"

"How is Alzheimer's connected to diabetes?"

"Does sugar cause cancer?"

"How do I reverse insulin resistance?"

"What should I eat to stay metabolically healthy?"

Or just say: "Map this book to my life."

Philosophy — 5 Rules to Remember

Insulin resistance is the common thread. Most chronic diseases — heart disease, Alzheimer's, cancer, NAFLD, PCOS — share one root cause: the body's cells no longer respond properly to insulin.
It's not just about diabetes. Type 2 diabetes is the late stage of insulin resistance. The damage starts years (even decades) before blood sugar rises. Waiting for a diabetes diagnosis means waiting too long.
Diet is primary. What you eat directly determines your insulin levels. The biggest driver of hyperinsulinemia is not fat or protein — it's refined carbohydrates and sugar, especially fructose.
You can reverse it. Insulin resistance is not permanent. Weight loss, low-carb diets, intermittent fasting, and exercise can dramatically improve insulin sensitivity.
The environment matters too. Toxins like BPA, air pollution, and chronic stress all contribute to insulin resistance through inflammation and oxidative stress.

Core Framework Quick Reference

Insulin resistance defined: Cells stop responding to insulin normally. The pancreas compensates by producing more insulin. High insulin levels drive chronic disease.
The seven deadly diseases: Heart disease, Alzheimer's, cancer, NAFLD, PCOS, type 2 diabetes, and kidney disease — all connected by insulin resistance.
The TG/HDL ratio: A simple blood test ratio that predicts insulin resistance and heart disease risk better than LDL alone. Ratio > 2.0 is concerning.
Fructose is uniquely harmful: Unlike glucose, fructose is metabolized almost entirely in the liver and directly drives NAFLD and insulin resistance.
Type 3 diabetes: Bikman presents the evidence that Alzheimer's is fundamentally a metabolic disease of the brain, driven by brain insulin resistance.
Environment matters: BPA, air pollution (PM2.5), and chronic stress all contribute to insulin resistance through inflammation.
Reversal is possible: Weight loss of 5-10%, low-carb diet, intermittent fasting, and exercise can dramatically improve or reverse insulin resistance.

Key Principles

Insulin resistance precedes disease by years. By the time you are diagnosed, the damage has been accumulating. Prevention starts long before symptoms appear.
LDL is not the villain. The book argues that triglycerides and HDL matter more. High triglycerides + low HDL = insulin resistance.
Alzheimer's is metabolic. The brain can use ketones as fuel. When brain cells become insulin resistant, they starve. This may be the core mechanism of Alzheimer's.
Cancer feeds on insulin. Insulin and IGF-1 promote cell growth. Hyperinsulinemia creates an environment where cancer can thrive.
Fructose from added sugar is worse than glucose. It bypasses normal insulin regulation and directly causes liver fat accumulation.
Intermittent fasting works by lowering insulin. It's not just about calories. Time-restricted eating gives the body periods of low insulin that are essential for metabolic repair.
Environmental toxins are a hidden contributor. We can't control all of them, but we can reduce exposure to BPA, improve air quality at home, and manage stress.

Anti-Pattern Summary

The core mistake this book corrects: the belief that chronic diseases like heart disease, Alzheimer's, and cancer are separate, unrelated conditions with different causes — when in fact they share a single root cause: insulin resistance, and addressing that one root can prevent or reverse most of them.

Self-Check

Recall Test:

"What is insulin resistance?" — reference/1 → Cells stop responding to insulin. The pancreas produces more to compensate. High insulin causes damage.
"What diseases are linked to insulin resistance?" — reference/1 → Heart disease, Alzheimer's, cancer, NAFLD, PCOS, type 2 diabetes, kidney disease.
"Is LDL the main cause of heart disease?" — reference/2 → The book argues no. The TG/HDL ratio is a better predictor than LDL alone.
"How is Alzheimer's linked to diabetes?" — reference/3 → Alzheimer's is called "type 3 diabetes" — brain cells become insulin resistant and starve.
"Does sugar cause cancer?" — reference/4 → Not directly, but hyperinsulinemia creates an environment that promotes cancer cell growth through IGF-1.
"What is NAFLD?" — reference/1 → Non-Alcoholic Fatty Liver Disease. Caused by fructose and insulin resistance. Can progress to cirrhosis.
"Can insulin resistance be reversed?" — reference/5 → Yes. Weight loss, low-carb diet, intermittent fasting, and exercise all improve insulin sensitivity.
"What's wrong with fructose?" — reference/1 → Fructose is metabolized almost entirely in the liver. Excess fructose directly causes liver fat and insulin resistance.
"What lifestyle changes help most?" — reference/5 → Reduce refined carbs and sugar, increase protein and healthy fats, intermittent fasting, regular exercise, quality sleep.
"What is the TG/HDL ratio?" — reference/2 → Triglycerides divided by HDL. A ratio over 2 indicates insulin resistance and increased heart disease risk.

Invocation Test: Question: "I've been diagnosed with pre-diabetes and my doctor says I need to lose weight. I'm confused about what to eat. Carbs? Low fat? Keto?"

Expected output:

First, pre-diabetes is a warning sign, not a life sentence. Your body is telling you something: your cells are becoming resistant to insulin.
The key dietary change is to reduce foods that spike insulin: refined carbohydrates (bread, pasta, rice, cereal) and added sugar (soda, juice, desserts, snacks).
The book advocates for reducing carbohydrate intake and replacing those calories with protein and healthy fats. This approach naturally lowers insulin levels.
Not all carbs are equal. Vegetables, berries, and legumes are fine in moderation. The problem is processed carbs and sugar.
Consider intermittent fasting: even a 14-16 hour daily fast can significantly improve insulin sensitivity by giving your body extended periods of low insulin.
Exercise is powerful: both resistance training and aerobic exercise improve insulin sensitivity independently of weight loss.
One specific action: start with one change — eliminate sugary drinks (soda, juice, sweetened coffee) for the next week. This single change can dramatically lower your insulin levels.
