Metabolical was very much a wake-up call for me — it’s not just about sugar; it’s about a food system engineered to keep us sick and snacking.

Dr Lustig weaves biochemistry with storytelling so you actually feel the stakes: insulin resistance, fatty liver, mood swings—the whole cascade. I appreciated how he separates real food from “edible products” and gives a doctor’s-eye view of what actually heals us. The truth is, it sharpened my mission: to prioritise whole, nutrient-dense foods of protein and fat origin, radically reduce carbohydrates as sugar and help clients avoid metabolic disease. A well-loved author and book….

Dr Richard K. Bernstein died at the age of 90 this year in 2025. Living with Type 1 Diabetes since he was a child, he studied medicine and went on to become a pioneer in diabetes, especially T1. His work transformed the landscape of diabetes management and inspired a global community to pursue better health through informed self-care. A man after my heart!

Through self-experimentation as a diabetic, he discovered that a low-carbohydrate diet, combined with precise insulin dosing, could stabilise his blood glucose and reverse many of his complications. Low-sugar and low-insulin dosing made up his “Law of Small Numbers”:

• ● Small carbs ⇒ small glucose rises. Less carbohydrate means smaller post-meal spikes.
• ● Small spikes need small insulin doses. When doses are small, any dosing error produces a small glucose error, not a big swing.
• ● Small doses are more predictable. Absorption variability matters less; you get flatter curves and lower glycaemic variability.

This book is a bible if you or a loved one have grappled with this debilitating disease, either Type 1 or 2 Diabetes. It’s a keeper! I’ve read it avidly, having family in both groups.
