You know, I've been talking about environmental toxins forever, and laundry detergent is a sneaky one. 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's 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. I really like how simple it is and how fresh and clean everything comes out without those unnecessary chemicals.

All right, so fasting, intermittent fasting. This is big time in the news now and I'm glad because there's some amazing benefits from fasting. Whether you're just doing a 16 hour fast fast or you're doing a 24 hour fast or a multi day fast, there are some incredible, incredible benefits, especially something called autophagy. And that literally is your body taking out the cellular trash. It's like a cellular detox. So that is fantastic. And the reality is it can be a quick way to reset your blood sugar, get your blood sugar really stabilized quickly. But before you do it, there's a couple things that I would advise. Number one, you want to make sure you're a good detoxifier if you're trying to lose fat. Whenever you're saying weight loss, I'm assuming you really mean fat loss, right? If you're trying to lose fat, then you've got to be good at detoxifying because your body stuffs toxins into your fat cells and then lowers your body temperature, lowers your thyroid function to hold onto it so that you don't have these toxins just floating around your body. So number one is you gotta be a great detoxifier. And so that means that you are a good sweater, you are pooping well, that you're eating a high fiber diet, doing a lot of sweating, ideally have an infrared sauna, shout out to my buddies over at Sunlight and sauna for mine. You're exercising, you're doing a lot of things to help with circulation. You got a lot of green plants, you're drinking a lot of clean, pure water, all those things. Then next up, I'm going to recommend doing the Sugar Impact diet. Why? Because this is going to help your body shift from being a sugar burner where you have to eat every couple hours, and if you don't eat, you're like, ah, I feel hungry. To being a fat burner where you can easily go four to six hours between meals, you're much calmer, just like I am right now. And you may even skip a meal and forget to eat. That is when you know you've moved into being a fat burner and you really want to be there. If you're going into intermittent fasting or fasting. Because if you're a sugar burner, relying on incoming every couple of hours and you try to Fast, you will fail fast. So first do the Sugar Impact Diet. That will prepare you to be able to intermittent fast with ease and fast with ease. Now, why do I love these things? Well, one of the things that we know is that if you lower your calories for an extended period of time, your body is wise and protects you from yourself and also lowers your metabolism to accommodate it. It downshifts, which is the very opposite effect of what you really want to have happening. So why I love intermittent fasting and fasting is that it naturally creates something called caloric variability where your calories vary. So you're not downshifting your calories, you downshift them maybe for a day or two or three, and then you bring them back up and then you downshift them. So you got good caloric variability. And you're also metabolically flexible. You can burn ketones for energy, you can burn fat for energy, you could burn sugar for energy. Your body's kind of like a great hybrid car and that's what we're really trying to do. So again, the process here, make sure you're a good detoxifier. You're putting in all of those strategies that help you detoxify on a daily basis. Then go do the Sugar Impact Diet and make sure that you're moved into being a fat burner rather than a sugar burner. And then move into intermittent fasting. And then once you've done that, you can graduate to full on fasting. All right, there you go. Let me know how it goes.
