Understanding how sugar affects your brain could change the way you eat for the rest of your life. In this video, Harvard and Johns Hopkins-trained neurologist Dr. Majid Fotuhi explains why sugar isn't just fattening; it can be toxic to your brain, even if you're not overweight.Dr. Fotuhi walks through what actually happens after a sugar spike: the insulin surge, the crash that drives more cravings, and the cycle that can lead to insulin resistance, inflammation, and damage to cells throughout your body. Then he shows what this looks like inside the brain: fewer connections between neurons, less growth of new brain cells in the hippocampus (your memory center), and more brain fog and memory loss.He also covers the research linking excess weight to a physically smaller brain at every age, from a study of over ten thousand adults to children ages 9–12 showing frontal-lobe thinning and weaker working memory. And he explains the brain biology of food addiction: why your brain's reward system can override willpower, and why overeating is often not simply a lack of discipline.Finally, Dr. Fotuhi breaks down what medications like Ozempic do in the pancreas, the stomach, and the brain, including the "food noise" many patients say quiets down, along with the tradeoffs researchers are still studying.Chapters:- 00:00 - Intro00:25 - How Sugar Affects the Brain01:33 - Insulin Resistance and Inflammation02:48 - Obesity and Brain Shrinkage04:28 - Hunger, Cravings, and Food Addiction06:03 - How Ozempic Works07:11 - Side Effects and Key Takeaways08:10 - Outro💬 Have you noticed sugar affecting your focus or mood?
