For non caloric sweeteners, stevia can be okay. But I would say the whole plant stevia, not riboside A, which is made by Cargill and Pepsi and Coca Cola. So that should tell you something about it. Also there's other kinds of sweeteners that you can use which is like monk fruit sweetener, which is I think my favorite. It's generally well tolerated. It's, it's tasty. I don't particularly like stevia because I think it causes problems. But any, any sweetener could be this brain stimulant. So be careful. Look for products with Rainforest alliance certified seal to make sure your stevia is grown in ways that are sustainable. If you want honey, you can check out the Ethical Consumer Guide. We'll provide the link in the show. Notes and sweeteners, you know, what are things we can include? Well, juice, pureed fruit juice, molasses, organic palm sugar, date sugar, coconut sugar, it's got a little lower glycemic index. Monk fruit sweetener, which is a non caloric sweetener. Organic maple syrup, honey, as I mentioned, stevia and monk fruit, I typically are the ones I would recommend, but sparingly an erythritol, some people can tolerate it but don't have that much. And what should we avoid? Well, we shouldn't be eating mounds of sugar of any kind, but artificial sweeteners like big. No, no liquid sugar calories. If you want to do one thing for your health besides the high fructose corn syrup, it's getting rid of sugary beverages. Liquid sugar calories are the worst because of how they affect your metabolism. High fructose corn syrup, don't eat that. Anything with the word syrup in the name except maple syrup. Any, any things that are all natural. You know, agave is natural. Sugar cane's natural, evaporated cane juice, natural brown rice soup is natural. That means it's good for you. So the arsenic, that's natural. Packaged foods that have added sugar, just stay away from that stuff in order to make a food taste good that's industrial food, they have to add sugar or salt or fat. And it's surprising. You know, there's more sugar in serving of prego tomato sauce than there are in two Oreo cookies, right? So salad dressings, granola, granola cereals, ketchup, soups, candy, yogurt. I mean, I was surprised. I'm Jewish and we had Passover, and I didn't even look at the label. I just bought some a jar of gefilte fish that my mother used to buy. And I'm like, this is kind of sweet. I kind of looked at the labels like it was like, full of sugar. And I'm like, why they put sugar in fish? So it's pretty much everything. And obviously, you know, refined sugars of all kinds of brown sugar, aspartame, sucralose, saccharin sulfate. Just pass on those things. And there are a lot of ways to enjoy sweetness. Also a little hack. Use a continuous glucose monitor from levels. That'll help you find out what things are affecting you and what are not. You can also eat protein and fat before you eat something sweet or carby. For example, if you drink a glass of wine or alcohol and empty stomach, you get a quick buzz, right? But if you. If you basically have it after a meal or in the middle of the meal, you don't get that instant buzz. Why? Because of the quick absorption. Same thing with sugar. We may not get, you know, a buzz, but our bodies don't get the buzz if we eat protein and fat before combined with diet. Exercise is really the most powerful tool for staying healthy and extending your life. My mom used to say whenever she had the urge to exercise, she would lie down till it went away, which I think she got from any young man or some comedian. But she followed that advice, unfortunately, and she didn't exercise, despite my hounding her. Of course, parents never listen to their kids. I mean, kids, whatever, something like that. Parents never listen to their kids. And she ended up being pretty frail and disabled the last decade of her life and not too functioning. So when you start thinking about how to take this approach of incorporating movement and exercise in your life, you can get really amazing benefits. I'm just going to kind of go through them because they're just so profound. It actually unlocks the body's longevity switches, the regenerative and reparative systems that are built into our biology. It activates all the longevity switches that I talk about in the book, particularly the four that have to do with nutrient Sensing pathways that are sort of meta to everything else. Insulin signaling, mtor, which is really important in terms of autophagy and cleaning up your cells. Sirtuins, which are important in DNA repair, and also ampk, which helps regulate blood sugar, insulin sensitivity, inflammation, and many other things. So it's pretty, pretty darn exciting. It also activates the body's antioxidant systems. It improves your cognitive function and your mood. It supports, I mean, they found that just walking helps prevent dementia, which is pretty cool. It supports your microbiome, it reduces inflammation. It helps you produce more mitochondria and help them work better and be more efficient and have better function. Because mitochondria is where you make energy and as you get older you lose energy. So you want to boost that. It also keeps you strong and functional. You know, I just came back from skiing out in Switzerland and I had really great time. Was privileged to be able to go there, and I was amazed. Like, I was just skiing along like I was when I was 30 or 40 and I was probably going a little too fast, but, you know, I like to do that. And, you know, I felt strong and able to do it. And it was keeping up with people half my age. So I think the body has the capacity it needs to do this. It also makes you happier and improves your mood and even improves your sex life, believe it or not. So what does the research say? And let's talk about some of the nitty gritty about how it works. If you really, you know, maybe you want to know about the science, maybe that'll motivate you. I probably doesn't motivate most people, but it kind of gets me all excited. I kind of like that I'm a little weird. But it really, the research is just, it's just unbelievable about exercise. When I started to dig into, you know, obviously you can look at exercise in anything and search on, on PubMed and learn about it, but I started to look at exercise and longevity and what it does. So we covered a little bit of this, but I want to sort of expand on it. It improves your telomeres, which are little caps at the end of your chromosomes that start to shorten as you get older and shorten your life. It actually lengthens your telomeres by exercising. It protects your telomeres, it optimizes all these longevity switches like ampk, which regulates blood sugar. People say, I'm going to take metformin for longevity. Well, exercise is way better than metformin for regulating ampk. It also activates Sirtuins, which help DNA repair, reduce inflammation, and improve your blood sugar control, which are really important. It also improves your cardiovascular and heart health. We all know it reduces the risk of heart attacks and strokes and improves your brain function and cognitive function. It also helps certain types of cancer, as I said. You know, we see the regulation of our biology through exercise, being media, through. All these mechanisms have to do with immunity and cancer prevention. So it's super great. And of course, it extends your health span and your lifespan. I remember being in Sardinia and I mentioned this guy, I think before, but his name is Pietro. He was 95 years old and he was like a shepherd. And he was just running up and down the mountains all day, five miles a day in this really rugged terrain. And he was bolt upright, you know, booming voice, clear eyes, you know, strong and, and mentally sharp. And I was like, wow, this guy's 95 years old. You know, most people 95 in America barely can kind of walk across the street or get from their bedroom to the bathroom. And here he is, you know, running up the mountain. So we have the ability to do that. And he exercised every day as a shepherd, not quote, exercise, but he just, that was his life. It also, it's incredible for diabetes, for blood sugar control. I mean, just walking after dinner is a great way to keep your blood sugar down, helps you become more insulin sensitive and, and very importantly, it helps you build muscle mass and function because as you get older, you lose muscle. It's called sarcopenia. And that leads to all these hormonal and metabolic changes that accelerate aging and lower testosterone, high, high cortisol, the stress hormone, higher blood sugar, worsening cholesterol, I mean, just lower growth hormone and increased cortisol. Like I said, it's just, it's really bad news. So building muscle is really important, and that's clearly only done by exercise. So hopefully listening all this, you realize you can't afford not to move. My basically philosophy is if you don't move, you won't literally, you'll be dead. So how can you actually incorporate more movement? What can you do without having to drag yourself to the gym? Now, I go to the gym sometimes, but I rather play. And I think there's a lot of options and you can just do simple things, like start with simple things, even five minutes a day. And if you don't have five minutes a day to do something, there's something wrong with your life. So you better look at that. So, you know, for example, I, I, I figured out I couldn't do 10 pushups when I was 50. So I, I sort of, I'm going.
