Chantel Ray:                 Hi guys. Welcome to this week’s podcast. Today’s guest is not only a chiropractic doctor and leading … He’s a leading expert in the weight loss field, but he’s also a personal testimony to the success of weight loss through lifestyle change. He himself has lost over 100 pounds in six months using his own weight loss techniques. So please help me welcome to the podcast, Dr. David Rendelstein. How are you?

Dr. David R:                  I’m doing okay. Thank you, Chantel. It’s nice to meet you. It’s nice to be on your show.

Chantel Ray:                 Well, so your program is called ThinTech Weight Loss Program. Tell us a little bit about your own health journey, how it led you to develop ThinTech. Give us a background.

Dr. David R:                  Got it. I’m like a lot of people, which is I’ve struggled my whole life with weight loss. I was a fat child, frankly. I was ridiculed. I was teased. I mean people can be cruel, especially young people who don’t really understand that you might be sensitive about that kind of thing. That’s how I grew up. I was never particularly comfortable in my body. At various points, I lost weight, but I always ended up gaining it all back, and I think probably a lot of your listeners understand what it’s like to be a yo-yo dieter.

Dr. David R:                  I like to compare it to Sisyphus who was a Greek king, and he was punished by the gods by having to roll a boulder uphill, and it would always inevitably roll back down. That’s really what it feels like to expend all that hope, to expend all that effort only to have to start over again. That’s caused a lot of people over time to really give up on their dreams and really give up on their goals of being healthy. So if there’s one thing I want to communicate to your listeners is we can’t do that. Life is really too short, and if we’re going to give up trying to get healthy, what exactly are we going to do for the next 40, 50 years or so?

Chantel Ray:                 Very true. What exactly did you do to lose the weight yourself? Give us three of your big principles that you did personally to lose the weight.

Dr. David R:                  Got it. I found this amazing program. It’s extremely structured, and it’s based on a few fundamental things. Number one is we have to address a person’s physiology. What most people don’t understand, Chantel, is that the body itself can become out of balance, and when it does, it can actually slow down. The metabolism could become terribly slow to where not only is a person’s energy down, but to where they become fat loss resistant. This is the struggle that a lot of people I’m sure have have stated to you. I try and I try, I do everything right but I can’t lose weight. Meanwhile, my friend, Suzie over here is shoveling crap into her mouth and she doesn’t gain anything. That’s the importance of physiology. That’s the importance of metabolism. So we want to be able to address that first of all.

Dr. David R:                  Secondly, we want a person to be held accountable. When a person’s on our program for the first little while, generally it’s a six week phase, we have them text us every day with their weight. We’ll ask them certain questions. We want them to understand certain principles. The third thing is we want a person to gain certainty or hope, because most of the time when a person’s been on this journey and has fallen repeatedly, there’s not a lot of certainty. There’s a feeling of being out of control and maybe they can’t do this. Maybe it’s not who they are anymore, being a lean and healthy person. So we want to restore that to them, and when we do that, Chantel, there’s really something that happens. There’s a magic that occurs when a person sees hope, when a person sees possibility for themselves. What we find is that it really ripples out to their families. People at work notice. They hear lovely things from their friends about how they’re showing up differently. It’s really fantastic.

Chantel Ray:                 Awesome. I love that on your site, you talk about the fact that you’re not counting calories. You’re not having cardboard meals. You’re eating real food that you buy at your local grocery store instead of a [Nutrofast 00:05:00], or a Jenny Craig, or one of those.

Dr. David R:                  Well, I don’t want to disparage other programs except for the fact that I do.

Chantel Ray:                 Yeah.

Dr. David R:                  Listen, let’s face it. We can improve on God and nature. We’ve been on this earth, people who’ve been on this earth for many thousands of years, and there are foods that are put here for us. There are certain nutrients that we need, and we really can’t do better than that with synthetic products. So we want a person … or processed foods, so we want a person to get back to nature. You have to eat good whole foods. This is what’s around to nourish our bodies. Now having said that, foods are not as nourishing and they’re not as nutrient dense anymore as they used to be unfortunately, because of all the toxins in the environment and farming practices, how they are today. So we supplement people with whole food supplements.

Dr. David R:                  I want people to understand, I mean, the vitamin industry, as you know, is a gigantic industry. They’re all different kinds of players. Unfortunately, not everyone is in it for the right reason, but I really believe that supplements make all the difference in the world, because we can’t create the energy that we need to burn fat if we don’t have the nutrients. We need the raw material. You can’t make a fire without having all of the logs that you need. That’s where supplementation comes in. So that combination, whole food supplements plus good whole healthy foods, that’s a winning combination.

Chantel Ray:                 Awesome. Now, what line of supplements do you guys advocate for?

Dr. David R:                  Well, we use currently only two different lines, and we vet things very, very carefully. Again, we’re only going to use supplement lines that involve whole foods. Now, the lines that we use, we use two. One is called NutriMost, the other is Premiere Labs. Those particular companies, they don’t even really make tablets. Very rarely will they even have a tablet. Why? Well, once you create a tablet, now you have to create agents that allow things to be held together, and very often these agents or excipients, as they’re called, they themselves are not healthy. So the supplements that we use generally come in capsule form. They’re actually foods broken down and put it into capsule form or they’re in liquid form. So like I said, we vet these very carefully. We only want to give the body that which is nourishing to it.

Chantel Ray:                 All right. Well, let’s jump right into the listener questions, and this first one is from Erica in Des Moines. “I have a terrible sweet tooth. As soon as I’m done eating, I have to have some chocolate. I even carry a bag of Hershey’s Kisses in my purse just in case I need some emergency purse chocolate. Any tips on how I can kick my sugar habit? Erica.” [crosstalk 00:08:28].

Dr. David R:                  That’s a great question. Thank you, Erica. I hope everyone out there in Iowa is doing well. So I would say there’s a few things, right? First of all, we have to understand that very often cravings are happening from physiological imbalances in the body. Let me give you an example. You mentioned chocolate. Well, often when a person craves chocolate, their body needs magnesium, so we have to give the body the nutrients that it needs. Be aware of the possibility also that there could be some, what we call, subclinical sugar issues, right? It’s not enough to come to the level of what might be diagnosed with diabetes, but you feel it. You’ll feel … All of a sudden, you’ll eat something and maybe have a quick burst, and then it’ll go downhill really rapidly. That’s where this idea of sugar addiction comes in because we don’t want to feel like that.

Dr. David R:                  We want energy. We want our mood to be good, and we know that we can have something that very quickly will do that. So the temptation to have it is very, very strong. It’s very, very powerful. We have to understand that we have to give our body what it needs so we have much less of a temptation, but in the meantime, we want to develop strategies. I’m going to give you one little cool tip that I think you’ll appreciate. There is a product out there. It’s called Crio Bru, right, C-R-I-O B-R-U.

Chantel Ray:                 Okay.

Dr. David R:                  Now I don’t have any relationship with them, a financial relationship. I get nothing for this, but this is something that we’ll recommend to clients. What is Crio Bru? Crio Bru is actually ground cacao, and you can brew it like you would brew coffee. So what I like to do is I like to brew this and then put in stevia, chocolate flavored stevia, and what I’m then drinking essentially is a hot chocolate, so it’s very satisfying. It satisfies that sweet tooth. It satisfies that craving for chocolate. There’s mild caffeination to it and you don’t feel like you’re missing out, and guess what? There’s no sugar in it at all. So that’s what I would recommend for you out in Iowa, Erica.

Chantel Ray:                 All right, this next one is from Ray in Bismark. “I consider myself a pretty healthy guy, but I am a little overweight, just like 20 pounds or so. All my blood work and cholesterol are in the normal range though, but I really need to lose the weight. Any tips?”

Dr. David R:                  Well, that’s a pretty wide open question, isn’t it? I’m not even sure where to go. I mean any tips. It’s typically thought of, Chantel, that all things being equal, calories out exceeding calories in will lead to weight loss, but I do qualify that by saying all being equal. Again, if the body, if the metabolism has slowed down, then it can become a struggle even if you’re doing everything right. My first tip, which I think you would probably agree everyone should do is let’s eliminate added sugars. I mean the one thing any weight loss guru worth his salt is going to say is let’s get rid of those added and excess sugars.

Dr. David R:                  Let’s get rid of processed foods. Let’s maybe skip breakfast a few times a week, right? Let’s include that intermittent fasting there. There are hormonal advantages and there are advantages into letting your body get into a modified fast state where it uses up all its sugar and then it starts eating the fat. So I think if you do those things and maybe increase your movement a little bit, I think those are great places to start.

Chantel Ray:                 All right, next one is from Tracy in Birmingham. “I’m so tired all the time. I can literally wake up at 10:00 AM, eat breakfast, take my dog for a short walk and then already be ready for a nap. What’s going on? Could it be my diet?”

Dr. David R:                  Well, it certainly could be. You said you’re from Birmingham. My understanding is that that in Birmingham it’s pretty easy to get some fried Southern food that could certainly lead to being tired. Listen, exhaustion, if you ask doctors across the country, exhaustion is one of the biggest reasons that people come into the office. Now there are so many things that can cause exhaustion. Certainly diet is one of them. Obviously, sleep issues are another. A lot of people have sleep apnea. Sometimes it’s undiagnosed. So without having too much information I couldn’t say, but again, I would start by eliminating processed foods. The simple sugars like that, that’s always a good place to start, and knowledge, data.

Dr. David R:                  Data is vitally important, which brings me to something, Chantel, I wanted to discuss which is this. I’ve created a test and I call it the thin test, and what the thin test is, is it’s an online evaluation. What it does basically is it enables people to identify their barriers to losing weight and to keeping it off, and then to be able to formulate plans for them to be able to address those barriers. That could be taken in my website. My website, we’re going to talk about this later, but just very quickly, it’s, and there if you click on the thin test, you can take it. There’s no charge, and actually we’re offering a 10 minute consultation to anyone in the country who wants to do this, to your listeners and there is no charge for that either.

Chantel Ray:                 Awesome. Well yeah, I love the questions that you have on the thin test. I looked it up online and it is there. They’re really good, thought provoking questions. So then you take that test, you submit it in, and then you’ll get to talk for free for 10 minutes with one of the coaches to analyze what those answers were. Is that correct?

Dr. David R:                  Yeah. So let’s talk about data. Let’s talk about knowledge, right? I mean, everyone wants to lose weight, as you know, and yet there’s a lot of knowledge that’s missing. Now, some of that knowledge has to do with what we’re talking about, right, the body and how it functions, but there’s more than that. I mean, let’s look at all the different forces there are that are working against us in our society. There are cultural influences. In the first 10 minutes when someone comes in, they always tell me their backgrounds. “But Doc, I’m Italian, but Doc, I’m Jewish, but Doc, I’m Hispanic.” I get it. I mean, there are really strong cultural influences. By the way, just an aside, is that no one ever takes away an Italian card from you if you don’t have pasta, all right? You need to know that your cultural identity is not going to be changed, but, but that’s one example of one of the forces against us.

Dr. David R:                  How about understanding? How well do you understand your body and what it needs to be healthy and to lose weight? How well do you understand how to choose the correct foods? That’s really important as well. How about motivation? Again, everyone wants to lose weight, but how many people really have the will and the drive and the push to where they’re going to take the actions that are going to allow them to do that? So this is what the test is designed to do. It’s designed to identify what these barriers are, to grade them, to actually give you a score, and then to allow you to come up with plans and programs either with yourself or with an office like ours, so you can address these things and finally be successful.

Chantel Ray:                 Let me ask you, I would love to hear about a day in the life of David. So what did you eat yesterday? Tell us about did you work out? What is your day look like on keeping healthy?

Dr. David R:                  Well, you’re asking me about a day in my life. I’m about to turn 51. I remember things not nearly as well as I used to. I don’t know if I could remember a day of my life. Let’s see, yesterday, I woke up. I did not have breakfast. Instead I had what we might call a bulletproof coffee. So that is a coffee where … and this is a great idea for people also. In fact, Chantel, if you’d like, for your listeners, I’m even … I’m willing to give them my personal recipe,

Chantel Ray:                 Okay.

Dr. David R:                  Okay. Also another free gift. There is no charge. This is wonderful. So the idea of a bulletproof coffee, it’s a coffee where you’re mixing in good, healthy fats that will satisfy you, that will raise your energy, that will feed your brain so you’re not so hungry. It allows you, it assists you with intermittent fasting and with fat burning. Okay, so here’s how I do it. I like to put in my coffee, coconut oil. Now, you have to experiment with your balance, but let’s say a tablespoon of coconut oil and sometimes I’ll put in grass fed butter, but in addition to that, I’ll put in flavored stevia, which we already talked about. I prefer hazelnut. Then I’ll put in a pinch of a good sea salt.

Chantel Ray:                 That tiny little bit of sea salt really makes it good. That’s what really makes the flavor.

Dr. David R:                  That’s right. You get it. What you have is you have all the elements, right? You have the frothiness, and you have the sweetness, and then you have that little bit of that saltiness, and I like to blend it up with an immersion blender. It’s basically a stick that goes right in the cup. So that’s the first thing that I do every single morning essentially.

Chantel Ray:                 Is there a certain brand of the hazelnut stevia that you use?

Dr. David R:                  Yeah, we always use Sweet Leaf.

Chantel Ray:                 Sweet Leaf?

Dr. David R:                  Sweet Leaf brand stevia is what we recommend. It’s a liquid, so that works.

Chantel Ray:                 How many drops do you use?

Dr. David R:                  Again, this is subject to a flavor. I have a bit of a sweet tooth, so I generally use three droppers. That way, when you, when you squeeze the dropper, it doesn’t go up all the way. So it amounts to a quarter to a half a drop for each squeeze.

Chantel Ray:                 Okay. All right. So you’ve got your bulletproof coffee in the morning and then what about for lunch?

Dr. David R:                  So for lunch, I believe yesterday I had sardines in olive oil.

Chantel Ray:                 Oh, that’s awful.

Dr. David R:                  Well, it’s an acquired taste. Not everyone loves … It’s awful. It actually has a lot of good stuff, right, so besides protein, and then I had a greens juice that’s-

Chantel Ray:                 What was in your green juice? What was in your green juice?

Dr. David R:                  There was, if I’m not mistaken, celery, kale, broccoli. It was something I purchased at Whole Foods.

Chantel Ray:                 Okay.

Dr. David R:                  So I had that, a little bit-

Chantel Ray:                 Did it have any fruit in it or was it all veggies?

Dr. David R:                  I think it had lemon. I think it had lemon in it. I try to keep my fruits to two a day, which is a pretty good general rule for most people. Not for everybody.

Chantel Ray:                 Okay.

Dr. David R:                  Then a little later on, I had a bunch of cherries and then I really … I think I skipped dinner. I think I overdid it on the cherries, and so I skipped dinner. I’m not recommending that. You should have your meals, have your good meals, try to make the majority of the food vegetables, right? I mean in this country, the protein or the carbs tend to be the largest part of the plate. So what I try to do is I try to have the largest part of the plate be vegetables and then a moderate amount of protein. Here’s a fun fact for many of your listeners, and this is why understanding is so important. What most people don’t know is that protein in excess can turn into sugar inside the body. All right, and so you want to have proteins be moderate proteins. Don’t have a steak that’s 48 ounces. Let’s just have it be a small part. We usually recommend seven ounces or so.

Chantel Ray:                 Got you. Well, thank you so much for coming on our show today and if you guys haven’t had a chance, go to, take that free test, get your 10 minute free consultation with one of his coaches. Dr. David, thanks so much for being on our show today.

Dr. David R:                  Chantel, thank you for having me. I have to say I went to Amazon, I saw your book there. There are a lot of great ratings for that. There’s a lot of stars there, so you’re really doing a good job helping people out.

Chantel Ray:                 Thank you so much. If you have a question that you want answered, go to We’ll see you next time. Bye bye.
