Interview with Dr. Will Bulsiewicz
Kimberly: All right, all that being said, Iâm super excited to have Dr. B. Iâm looking at him on Skype right now. Heâs in Charleston, South Carolina. Hi, Dr. B.
Dr. B: Kimberly, itâs such a pleasure to be here, and I just want to take a moment because I have always wanted to do this, and I just want to say, hey, beauties. Hey, beauties. Iâve always wanted to do that, and Iâm probably going to do it five or 10 more times during this, and I hope you wonât hold it against me because this is a once-in-a-life opportunity. Itâs a once-in-a-lifetime opportunity to say hello to the beauties.
Kimberly: I love it.
Dr. B: I want to say, hey, Beauties.
Kimberly: Well, you know what we say, Dr. B, is that everybody is truly beautiful in their own way. So here at Solluna, we talk about our cornerstones of true beauty, which are food, body, emotional well-being, and spiritual growth. So when we talk about beauty, itâs deeper than just, oh, I have great hair or I have awesome makeup on today, but really connecting with our unique expression, ourselves, being comfortable being ourselves, where real confidence comes from.
Dr. B: I think thatâs so important, by the way. I think thatâs so critically important to⌠The older that I get, the more that I realize that every single person is beautiful in their own way. Everyone is bringing something thatâs amazing to this planet, and letâs just celebrate that.
Kimberly: I love it. And I know you have a daughter as well, and I think especially for women, itâs really tough growing up in such an image-based society where⌠With Instagram, itâs always comparing how one looks in their lives and social media in general. Itâs a really tough world now to raise children, I think. So instilling that idea that it really does start from the inside out is really important.
Dr. B: Itâs interesting; I can relate to that so much being a dad. My daughter is six, and my wife was actually⌠Before we got married, my wife was a model. Thatâs what she did for a living. But my wife is the most beautiful person I know on the inside, and we have⌠Itâs very interesting for us to frame how weâre raising our daughter because my wife basically said, âLook, I was in that industry. This is what I did for a living, and I want to raise her differently so that she doesnât associate that with her self-image and instead thinks of herself for the beautiful artwork that she can create and how intelligent she is and how creative she is and all these other wonderful things, and not let basically our society and our culture, the way that we associate value to that and frankly over-value that, not allow that to put her in a place where she feels thatâs what really matters,â because itâs not.
Kimberly: Exactly, exactly. Itâs all surface. And one of the things Iâll share with you, Dr. B, is on my journey, I had a lot of bloating issues and constipation and acne and a lot of things that actually made me put my head down, and I couldnât look in peopleâs eyes. And when I started taking care of my gut health and healing my candida and taking probiotics and giving up dairy and being plant-based and all these different things that we teach, it really⌠When I talk about beauty from the inside out, it was very magnetic. It felt like I was able to just have this different shift in my energy, and I became more confident. I didnât have to use caffeine. My skin cleared up. So physically, yes, I started to feel a lot more confident in my looks, but I just felt a lot more connected to myself.
A glimpse into Dr. Bâs new book, Fiber Fueled
Kimberly: So I really am passionate about gut health. Iâve been talking about it since my first book. Now thereâs five books, but I always touch on gut health in some way. And Iâm really excited to get into your book, Dr. B, which is brand new. It actually publishes on May 12th, so congratulations, by the way.
Dr. B: Thank you. Yeah.
Kimberly: Fiber Fueled.
Dr. B: Fiber Fueled. When you crack open Fiber Fueled and you go into the intro, youâre going to find a story for me, my own journey, thatâs very similar to yours, Kimberly, in my own way. In my own way.
Kimberly: You gained weight.
Dr. B: Yeah. I was 30 years old. I was 30. I felt like I was 60. Seriously, I gained 50 pounds relative to what I weighed in high school, which is a tough pill to swallow for a guy who always thought of himself as an athlete. I was a great athlete in high school. I was up 50 pounds. I had low self-esteem, low energy, high blood pressure, and was just kind of riddled with anxiety. Professionally, I was the Chief Resident at Northwestern in Chicago at the time. This was after Georgetown. You and I both have a Hoya connection.
Kimberly: Yes, we do.
Dr. B: So I was in Chicago. I was the Chief Resident. I was accomplishing all these things from a professional perspective, but I felt terrible on the inside. I didnât like the way I looked on the outside, and I didnât feel good about myself, even though I was accomplishing all these things. It was discovering a plant-based diet and the way that it healed my gut, and next thing I knew, it naturally reversed these things. I tried to exercise my way out of it.
How Will came across the plant-based diet
Kimberly: Sure, like a lot of us do. How did you find a plant-based diet? How did it come across your life?
Dr. B: So here I am. Iâm in my early 30s. Iâm single, again overweight, trying to out-exercise it, and I meet the person who ultimately becomes my wife.
Kimberly: Ah!
Dr. B: And we go out on a date, and for me, it was like standard. Okay, am I getting the rib-eye, or am I getting the pork chop? And we go out on a date. Seriously, I mean-
Kimberly: It sounds like me and my husbandâs first date.
Dr. B: Itâs probably the same. And we go out, and she would turn to the waiter, and she would go, âLook, I know this is not on the menu, but could you ask the chef if theyâd be willing to just make a plate full of plants? Take a whole bunch of sides, and make it look nice, and just bring that out.â
Kimberly: Thatâs what I always do at those kinds of restaurants.
Dr. B: Yeah.
Kimberly: Thatâs the best option.
Dr. B: Yeah. Well, I think it is the best option, but I didnât understand that, and I had never been around someone who ate this way.
Kimberly: Yeah, and you didnât really learn about nutrition in medical school.
Dr. B: I knew nothing about it, and the problem is so here I am-
Kimberly:
Dr. B: Well, Iâm a normal guy, right? Iâm a medical doctor, but Iâm also a completely normal guy. And the problem is that the normal guy was suffering because I ate the same way that I always ate, and in my mind, it was like, âWell, why would this be any different? This is what I was raised on.â
Kimberly: But nowhere in medical school was there a discussion about different diets or whole foods, fiber, nothing?
Dr. B: I think you know the answer to this question, that in medical school-
Kimberly: No classes.
Dr. B: They donât teach us that. They give us nutrition, and nutrition is this: Weâre going to ask you about these rare micronutrient deficiencies that you literally are not going to diagnose in your entire career, and thatâs what weâre going to quiz you on. And thatâs nutrition in med school.
Kimberly: Wow.
Dr. B: And you do that for two weeks.
We discuss the lack of formal teaching connecting how youâre eating with how youâre feeling and imparting that wisdom to patients
Kimberly: I ask every doctor this, and I get the same answer, but it still blows my mind that here you are, 30 years old. Youâre a chief resident. Youâre working in a hospital, working with all these people, and yet there hasnât ever been any sort of formal teaching in your life connecting how youâre eating with how youâre feeling and imparting that wisdom to your patients.
Dr. B: 100%. And then the issue is I canât figure out how to get myself out of this. Iâm like, âHow am I supposed to fix myself?â Iâm trying to exercise. Iâm exercising six days a week, 30 to 45 minutes in the gym and then go out and do a 5 to 10K, and I canât get myself out of it. What opened my mind was meeting my wife, who ate a way that I had never been around before.
Kimberly: Wow!
Dr. B: And I said, âYou know what? Iâm just going to⌠â This was like a baby taking his or her first step. I was like, âIâm just going to try this. Tonight, instead of going to Hardeeâs and getting the bacon double cheeseburger and the hot dog, instead of that, Iâm going to go home. Iâm going to make a smoothie.â
Kimberly: Wow!
Dr. B: And I did it, and I instantly⌠I felt full. I was satisfied. I was energized. I did not have the post-meal hangover, and that brought me back for day two.
Kimberly: Wow!
Dr. B: And I came back on day two and day three and four and five. The next thing I knew, my hair was changing. It was getting thicker.
Kimberly: Incredible.
Dr. B: My skin was becoming more radiant.
Kimberly: You pretty much went the all-or-nothing route. You went completely plant-based right away. Never turned back?
Dr. B: Actually, no. For me, it was a multi-year thing. So I started to drift in this direction and it was like small changes that were compounding over time to leading to huge results. Small changes, because I made them a habit, were giving me huge results. And then I got to a place where I was pescetarian, and I was like, âYou know what? I just want to see what happens. I just want to see.â And I decided to go all the way. I got rid of the dairy, the eggs, and the fish, and I lost another 15 pounds. And I stepped on the scale, and there was the same weight from high school again. I was finally there.
Going from a rib-eye eater to fully plant-based
Kimberly: Wow! So it was over⌠How long was that period to actually take the leap? And some people decide not to take that last leap. We always say small steps. It doesnât have to be all or nothing. But in your case, how did you go from a rib-eye eater to fully plant-based?
Dr. B: It was three or four years. It was three or four years, and I got to this one place⌠One of the craziest moments in the whole story is I got to this place where I⌠Okay, my daughter, who is six right now, was a newborn. And it was just after my residency and my fellowship, and I was working insane hours. Iâm not exaggerating. Literally already in the hospital, physically in the hospital at 5:00 AM and going home at 11:00 every night.
Kimberly: Oh, my goodness.
Dr. B: And I did that all week, and itâs really crushing to a person when you go home and your wife and your newborn child are both asleep, and you wake up in the morning and theyâre both asleep, and you repeat that for a week. So I get to the end of the week, and Iâm like, âMan, youâve got to treat yourself. You have earned something.â All right? So I decided to go to the old steakhouse that I used to love, and at this point, I had not had a steak in years, and I was like, âIâm just going to go and get a rib-eye.â And I went to the bar, and I sat down, and I ordered the steak, and it came, and I was like⌠And this was not an ethical thing. This was like I wanted this steak. I felt like I had earned this right. But it smelled funny. It smelled funny. It didnât smell appealing to me anymore. And then I went and I took like two bites, and I was just like, âThis is actually kind of gross.â
Kimberly: I love it. You change as you go. Isnât that incredible?
Dr. B: Your taste buds change.
Kimberly: Yes, yes.
Dr. B: Which is crazy. Even as a doctor, thatâs hard for me to believe.
Kimberly: I experienced the same thing with cheese, Dr. B. I used to be obsessed with cheese, and I loved it. I loved cheese on pizza, and it took me about two years to get off the dairy when I started learning about what it was doing to my body. And now when I look at cheese and itâs ooey, it just looks really gross to me, and it smells gross, whereas I used to have such intense cravings for it. So while youâre in it, itâs hard to imagine that you donât want it anymore, butâŚ
Dr. B: Well, and thatâs the thing. We get so used to eating a certain way that itâs hard for us⌠Most of us, we eat the food that we love, right? Weâre not eating the food that we donât love.
Kimberly: Of course.
Dr. B: So itâs hard to imagine drifting away from something that youâre very used to.
Raising children who are plant-based
Kimberly: Are your children plant-based?
Dr. B: Yeah. My children are completely plant-based.
Kimberly: Amazing. Like, why-
Dr. B: Weâre delighted.
Kimberly: Yes. I always say Bubby, my son⌠Thatâs his nickname. His nameâs Emerson, but he has never been to the doctor except for the standard checkups. He has so much energy. Heâs doing great, and of course, the baby thatâs in my belly right now has been plant-based since conception, soâŚ
Dr. B: Well, I honestly believe⌠Honestly, Kimberly, I believe that plant-based since conception is amazing, amazing for fetal development, and then I think it just keeps paying forward from there. And whatâs really interesting is that children are born with the taste buds based upon the food that you ate during pregnancy.
Kimberly: Is that true? Because Iâve heard⌠I like to believe that. Iâve heard different things about that. Have they proven that now?
Dr. B: Have you ever had broccoli sprouts?
Kimberly: Yes, all the time.
Dr. B: You know how bitter they are. Okay, yes. So Iâm obsessed with broccoli sprouts. I think that theyâre amazing, but you have to embrace the bitterness, because itâs the bitterness that actually is destroying cancer and protecting your body.
Kimberly: Yes.
Dr. B: Right? But itâs such a bitter food. My son, Liam, came out smashing broccoli sprouts. Like six months, seven months, eight months, nine months old, once we started giving him solid food, he was smashing broccoli sprouts, and itâs because during pregnancy my wife was smashing broccoli sprouts.
Kimberly: Amazing. Yeah, the same thing with my son. He just drinks all the GGS. He does have sprouts, but just heâll take a whole head of broccoli and eat the whole thing raw. So he does like the same things. I just didnât know if there was actual clinical research on that. But anecdotally, I can say it was my experience, for sure.
Dr. B: All right, fair enough. I have not seen clinical research explicitly on that, but I mean just-
Kimberly: Yeah, it makes sense.
Dr. B: It blows my mind that a child would eat broccoli sprouts because, as an adult, I think itâs hard for adults to do that. You know?
Reversing a not-so-perfect diet for our kids and adults
Kimberly: Well, this part of the book, I think, is really interesting, where you talk about toddler poop and implanting it in the mice and basically how, from looking at feces of these young children, you can see a predisposition towards certain things like asthma. But for the people that are listening to this right now, saying, âOh, my gosh. I effed up. I did not give my kid healthy food, or I didnât eat really healthy when I was little,â what hope can we give about reversing some of this? And not all of us ate ideally when we were small.
Dr. B: I want people⌠Iâm talking to the Beauties directly right now.
Kimberly: I love it.
Dr. B: Yeah.
Kimberly: Talk to them. Talk to us.
Dr. B: I want to talk to the Beauties, and I want you all to know that I donât want you⌠I feel like itâs so easy to feel guilty in our modern culture as a mom for imperfections, and itâs almost like people feel like youâre being held accountable, or maybe in some cases, people are holding you accountable, and thatâs just not fair. And thereâs only so many things that you can control. So let me say this. My kids⌠Sometimes youâll see me post, and itâs like⌠Well, because itâs Instagram, I can only say so much. But sometimes youâll see me post where I talk about the effect of a Cesarean section or the effect of antibiotics at a young age. I want you guys to know, both of my kids were born by C-section.
Kimberly: Oh, yes, I had a C-section after a failed home birth. Yeah, I get it.
Dr. B: And your kids can be perfectly healthy when theyâre born by C-section. Your kids can be perfectly healthy if they have to take antibiotics. Your kids can be perfectly healthy if they didnât eat a perfect diet, if they ate a lot of chicken nuggets. Itâs okay. Itâs okay. But I think that the point is weâre all just trying to do our best, and the science helps us to understand what path to follow.
Kimberly: Exactly. So even if we maybe didnât have the best start, or we didnât⌠Now weâre learning, and we have a different diet than when our children were small, there is⌠The gut is so dynamic itâs able to shift and change as we change our diet, so at any point, we can make positive change.
Dr. B: You can change your diet literally your next meal, and that will start to change your gut immediately. Literally, in less than 24 hours, your gut is already starting to adapt to the dietary changes that youâve made, and we have studies that show that.
Kimberly: Amazing.
Dr. B: So itâs a beautiful thing.
Dr. B shares how he started to focus on the path of gastro health
Kimberly: When you became plant-based, is that when you decided to focus on gastro health, or were you already veering along that path?
Dr. B: I was already in it. I was already in it.
Kimberly: Oh, interesting.
Dr. B: Yeah, I was at the University of North Carolina. I was in a combined GI specialty, like gastroenterology-plus-epidemiology program. Iâm just a nerd. Iâm a total nerd. So I was in this special program, and I thought of myself as a cancer epidemiologist during this period of time in my life. So what kind of is interesting is I had the science background to read these studies, and Iâm a person who values the science. I canât change
