In this YouTube presentation, Dr. David Perlmutter explains that excess body fat, specifically white adipose tissue (WAT), functions as an endocrine organ that secretes a variety of adipokines—such as tumor necrosis factor‑alpha (TNF‑α), leptin, and adiponectin. These signaling molecules influence inflammation, immune regulation, oxidative stress, and appetite, thereby creating biological pathways that link obesity to a heightened risk of coronary artery disease, Alzheimer’s disease, diabetes, and certain cancers. He references a March 2016 study published in the Journal of Neuroinflammation that provides mechanistic evidence for these connections. Perlmutter concludes with practical dietary advice: reduce carbohydrate and sugar intake and increase consumption of healthful fats to maintain a lean physique and lower disease risk.

Hello everybody, Dr. David Perlmutter here. I'm in the little village of Wanaka, which is a lakeside community in southern New Zealand, on the South Island of New Zealand. And what I'd like to talk about today is body fat. And, you know, we've known for quite some time that there is a strong relationship between excess body fat and risk for certain disease states. For example, like coronary artery disease, Alzheimer's, and obviously diabetes, and even cancer. But we haven't fully understood the mechanism whereby that happens. What is the mechanism that relates body fat to risk for these situations? And this new report, and you'll see the hyperlink, really characterizes what excess body fat does, really what white adipose tissue, which they abbreviate WAT, What does that do in the body? You know, for years we've looked upon body fat as simply being a storage depot for calories, and it is. But now we recognize that body fat is actually in and of itself an organ in the body, acts as really an endocrine organ. And that body fat, white adipose tissue, secretes chemicals called adipokines. Adipo meaning fat. Like, for example, tumor necrosis factor alpha and even leptin, which has a role to play in regulating appetite. Adiponectin, for example. These are chemicals that are secreted from our body fat that have a huge role to play in the body in terms of things like inflammation, immune regulation, and appetite, as well as even acting to regulate Oxidative stress, the action of free radicals. So I'd like you to take a look at this study. It's a little bit technical, but I think the take-home message is that when you look at this research published in the Journal of Neuroinflammation just in March of 2016, when you look at this study, it really finally helps us to connect why it is that we see such an increased risk for some of our most pernicious maladies In people who accumulate body fat. So it is yet another argument in favor of keeping yourself trim. How do you do that? You do that by lowering your carbohydrates, lowering your sugars in your diet, and actually eating more healthful fat. So take a look at the study. I think you'll find it very interesting, and I hope you enjoy. I'm Dr. David Perlmutter. Talk to you soon.
