Recently, I had the delightful opportunity to chat with Dr. Robert Lustig at a conference where he delivered the main address. We had previously collaborated on a panel at UCLA in 2022. If you're interested, you can watch his presentation starting at 34:15 here. Dr. Lustig is a renowned expert on metabolism, so I took the chance to discuss my recent post on the lipid energy model with him. He shared a research paper he contributed to, promising it would clear up any confusion. The post below is a summary of that paper, which you can read here. This research brings together four main theories into a single OBS/Redox model of obesity.

Therefore, a diet high in processed carbohydrates, as recommended by MyPlate/My Food Pyramid, may inadvertently contribute to obesity, diabetes, metabolic syndrome, heart disease, and other health issues by disrupting normal metabolic processes and promoting an imbalance in energy intake and storage. Furthermore, the effects linger after diet changes, as determined by a reanalysis of a feeding study I will discuss in this post today.
