A lot of them contain harsh chemicals like dyes, preservatives, and even UV brighteners. Those brighteners don't actually clean anything, they just coat fabric so your eyes think things look whiter or brighter. That's more chemicals I don't want on my family sheets or skin. And if you've got sensitive skin or allergies around the house, this can be a big problem. That's what got my attention about Earth Breeze. It looks like a dryer sheet, but it's actually laundry detergent. You toss one in the washer and that's it. No pouring, no mess, and no heavy plastic jug. Their packaging is lightweight cardboard, which helps reduce plastic waste. And if you choose the fragrance free option, it's gentle, hypoallergenic, non irritating and non sensitizing.

Foreign what if I told you that something as simple as your blood sugar levels could be the key to successful fat loss as you age? Well, it's true. So I want you to throw out everything you've learned about calorie counting, avoiding fat, and other outdated weight loss advice. I'm going to walk you through how to eat your way to your ideal body composition. So. So, blood sugar balance is important for fat loss because it helps the body burn more fat more efficiently. When blood sugar isn't balanced, the body is more likely to store fat and become resistant to the effects of insulin. Then you're less able to access stored fat for energy and burn it. Now, when you eat sugary processed foods and snack all day long, you know what's happening. You're keeping your blood sugar high, and high blood sugar levels well, then they trigger an insulin release. And then if insulin stays high, it.
Basically locks the doors to your fat cells.
Beyond that, high blood sugar levels can also lead to a damaging kind of inflammation, chronic inflammation. And chronic inflammation can also block fat loss. Plus, high blood sugar means glucose isn't getting into your cells. Your cells basically are resisting insulin, right? And glucose can't do what it needs to do. And this insulin resistance eventually paves the way for type 2 diabetes, heart disease, and other bad things. So, goal is we want to keep blood sugar stable and insulin to come up and then to come back to low. And we do this first by eating by the plate. And you've heard me, if you've been listening to the videos, talk about eating by the plate. This is basically the trifecta of protein and healthy fats and fiber. So starts with protein first, and here's why. I want to make sure that you're getting at least 30 grams of protein at each of your three meals. Protein, especially when you eat it first. This is key, critical. It's going to help stabilize your blood sugar levels. Now, beyond that, protein is more thermic, it's more satiating. But what we're really looking at here is how to make sure that we're keeping your blood sugar level stable. And we know that protein plus fiber slows down, stomach emptying helps you feel fuller, longer, and then that they both work together, protein and fiber, to keep your blood sugar level stable. They won't go up as high when you eat right. And that's super important. Now, along with what you eat, you're going to want to make sure you get a few specific nutrients that can help balance blood sugar before we go into the supplement ones. Here's some other things that you probably wouldn't go. That's not a nutrient. But I think of them like that. Remember foods where we first get our nutrients right? And one of the ones that you may not be thinking about is lemon juice. I drink something every day and I love to do this before lunch. And it is called Suja Lemon Love Shout out. And what it is is lemon juice, a little stevia and cayenne pepper, which of course helps boost your metabolism a little bit. But lemon juice has been shown to lower the blood sugar response to a meal. Similarly, vinegar does that too. So you could make a salad dressing with extra virgin olive oil, get those great polyphenols for your gut microbiome, and then add in some apple cider vinegar and. And vinegar can actually act like the diabetes drug metformin to improve insulin sensitivity. Like, these are things we totally need to take advantage of. I also love to take some apple cider vinegar and put it into green tea. We know green tea can help with insulin sensitivity. I am obsessed with berberine. Berberine is this botanical extract that influences multiple pathways in blood sugar metabolism and supports insulin sensitivity. So this is definitely one you want to check out. And also omega 3s. Now, I always talk about omega 3s. There's like they do all these great things. One of the things, of course, is they help with lowering inflammation. And as we know, that inflammation can lead to insulin resistance and diabetes. But they can also help resensitize your insulin receptors. So they do multiple things. I'm going to beat this horse dead. I've done it a bunch of times. We got to talk about artificial sweeteners when we're talking about blood sugar. So there was a study that looked at the impact of three popular artificial sweeteners. Saccharin, sucralose, aspartame. And they looked at this on two different types of gut bacteria. And here is what is crazy. The equivalent of just two cans of diet soda could turn healthy gut bacteria into pathogenic or disease causing bacteria. Okay. We also know that artificial sweeteners can lead to calorie dysregulation. What's that mean? You can't calibrate the degree of sweetness and the amount of calories you're eating. And you know what that means? You overeat. So bad news, no artificial sweeteners, because they're bad news. But good news is there's plenty of great options out There. Like if you're eating sweet, if you really like or dying for sweet, please read the Sugar impact diet and learn how to tame your sweet tooth. But if you want some sweet stevia, monk fruit and my favorite, allulose. Besides food, what else is there that's impacting blood sugar? Well, one of the big ones is, is meal timing. Because of course it's not just what you eat, right, but it's also when you eat. And the first thing that I want you to look at is, is how you space your meals and when you eat your meals. Here's how this all works. You're waking up in the morning, you want to eat two to three hours after waking. Not right away because you still got to give your pancreas the time to go wake up, right? But get up in the morning, meditate. If you're going to do a fasted workout, now's the time. And then you'll eat two to three hours after waking up. Then I want you to eat every three to six hours. And this is important, no snacking every time you eat. Remember, you're raising blood sugar. When you raise blood sugar, you gotta raise insulin to bring the blood sugar back down. If you're eating every two hours, your body's never having a chance to, to get that insulin back down to fasting levels. That means that you're locking the doors to fat cells. We're eating every three to six hours. So let's say that you wake up 6am, you have breakfast at 9am and then you have lunch maybe around 1. Now the next thing you want to make sure that you're doing is stop eating three to four hours before bed. Three hours is the real cutoff. We want to make sure that body can do what it needs to do while it's sleeping. What I really want you to look at is eating within, somewhere between. You know, I find for most of us a 9 to 10 hour window is great. Now I mentioned sleep a little bit here. There's a study that showed that a partial night's sleep deprivation, just a little bit like, you know, you got five to six hours instead of your seven to nine hours, can lead to insulin resistance. You can be doing everything else right, eating correctly, exercising, and you can get have issues with insulin resistance because of poor sleep. One of the things that happens with insulin resistance, if your insulin's out of balance, it's going to mess up your hunger, regulating hormones like ghrelin. And again, remember, your pancreas is snoozing. So insulin levels should Be lowest at night because melatonin's up, insulin's down. And here's what's also cool. One thing you can do to help with this is take melatonin. So in my sleep candy, I have melatonin. If we take melatonin before bed, it can actually help improve insulin sensitivity, it can help lower inflammation, and it can help increase the hormones that help regulate blood sugar balance. How cool is that? So what do we want? 7 to 9 hours of quality sleep every single night. So if you are going, I still can't quite get that thing together. Check out some of my other videos on sleep and my blogs. I've done so much on this because it's so super duper important. And the other thing that's important, and boy did I learn this during the pandemic, is stress cortisol. We've all heard about this, what your adrenal glands pump out. It's ideal, like short term, we got to have this. It brings you, gets you, wakes you up every morning. And it's going to be something so your body can utilize glucose. It's important. We would die without it. But we need to be able to have our body come up in the morning and then have a nice curve where it's coming down throughout the afternoon and low in the evening. Where we get in trouble is when we have elevated cortisol when it shouldn't be. And what happens if we have elevated cortisol where it shouldn't be is your blood sugar will be higher than it should be. And when I look at at what we need to do to be healthy, it's course sleeping well, it's of course eating well and supplementing. It's exercise and stress management. And stress management means find something that brings you bliss, whatever that thing could be for you. One thing that I hope brings you bliss is exercise. Because just even a single exercise session can improve insulin sensitivity for at least 16 hours post exercise. And that's for healthy people and type two diabetics. And by the way, like the most important thing of all to do is move. It's the most important. And so like, don't get all bogged down in the best type of exercise, how long, everything else, and then don't do anything right. Most important of all, move more. And one of the things you can do as a hack is walk after you eat. It lowers the blood sugar response to the meal. But if I were going to look at the most important exercise, we want you moving more, we want you walking as much as possible. Park farther away. You know that and it's easy to do. Here's my hint. Get a big dog. But the next thing is build muscle. If you're over the age of 40 and you're not using it, you are losing it. One percent a year doesn't sound like much, but how much is that after 10 years? A lot more. And then the age of 60, we start losing 2% a year. So we've got to be doing some exercise to help us build muscle. Muscle is really where we are. Using sugar, it's I call it the sugar sponge. During that workout, you know what you're using for fuel, not fat. When you're doing heavy, hard workouts, you're using sugar. You're using the sugar stored in your muscles. You're converting the fat and turning it into sugar to use it as muscle. So it is super duper critical to use to do resistance training and build muscle mass. In fact, higher muscle mass relative to body size is associated with better insulin sensitivity and lower risk of diabetes. You want to make sure you're drinking at least half your weight in ounces of water a day. And I think that's kind of a like, drink that. But what if you're sweating more? What if you're like, I just did a sweat lodge. Holy smokes. What if you're doing the sauna? What if you're working out hard and you want to be doing these things right, you want to be sweating more, it's detoxifying. You're going to need more. So just be aware of that. And one of the ways you can tell if you are well hydrated is.
Look at your pee.
Is it yellow or is it clear? Like, you do not want to have a, like a yellow toilet. You should be continuing to pee. So you. Your urine is getting clearer and clearer. Now, obviously, if you're taking B vitamins, that's a different story, but that's one of the things you want to be looking at. Finally, I am a big fan of using a continuous glucose monitor. I always say what you track, you can improve, right? What you measure and monitor, you can improve. And you really would know, have no way of knowing this information with a continuous glucose monitor unless you do this. Because if you're trying just to finger prick, you're getting a snapshot. These can be amazing for you to give this, this great glimpse. And if you're wondering what it is, it's just this little sensor. And literally my husband will put. Just stomp it onto my arm. Stomp, right? And then it goes on there. It's got a little tiny sensor under your skin. You can also put on your belly. I found that very uncomfortable. So I put on my arm and then it's then I have a little app and I just have the app hold the app up to the monitor and then it's just tracking my levels. And again, you see in real time what the things you're doing, how they're impacting your blood sugar for the good or for the bad. And these things are super affordable. And this isn't like, oh, you need to wear one forever. You want to see this in real time. So you learn, right? You learn about your food and your activity and all the different things. If you want to learn more about using one of these CGMs and you want to find other resources for balancing blood sugar, for boosting your metabolism, and most importantly, da da da, reaching your body composition goals, I've got plenty of actual tips and tools you can start with today, so add this playlist to your queue.
