Food Babe 25.04.2022 44:50
Toxins and chemicals and poisons...oh my! Today we dive into the "investigations" of Vani Hari, aka the Food Babe, and her wild (and wildly unsupported by literature) claims about food additives, pesticides, GMOs, and more. Vani would have you remove anything from your diet that contains anything added lest your want your health to suffer, and we'll explain why this alarmist way of...
Goop 18.04.2022 39:16
On today's episode, Emily walks us through the sometimes hilarious, sometimes frighting product offerings of Gwyneth Paltrow's wellness brand Goop. What started off as a harmless food newsletter quickly grew into brand that promoted almost all psuedo-science that is out there. We talk about crystals, vagina eggs, and of course, Goop's nutrition offerings and recommendations. A remi...
Probiotics and Gut Health 11.04.2022 41:13
We have trillions of bacteria living in our guts, and they may have more of an influence over your health than you think. In this episode, we tackle a popular, but complicated, topic of the symbiosis between what we eat, our gut bacteria, and our overall health. A word of caution that this episode may leave you with more questions than answers, but we deliver the most current research on this topi...
FASTer Way to Fat Loss (& Vegetable Oils) 04.04.2022 48:10
Why do 1 diet when you can do 4 diets at once?! Today, we examine Amanda Tress's program FASTer Way to Fat Loss, which does all that and more! Plus, for the low, low price of $5,000, you too can have a meaningless nutrition certification! Today's BS PS is a bit of a longer segment were we examine all the misrepresented claims about vegetable oil and other seed oils in the media lately. ...
"The Plant Paradox" Book Review Pt. 2 28.03.2022 41:24
Today we dive further into the habit hole that is Dr. Steven Gundry's diet book about how bad beans, legumes, fruits, most vegetables, and whole grains are for you. This episode looks at his *very unrealistic* diet plan, his *very expensive* supplement line, and a whole lot more. A reminder that this podcast is the thought and opinions of the hosts only. Visit rdsvsbs.com and check out the...
Lectins: "The Plant Paradox" Book Review, Pt. 1 21.03.2022 42:37
In another addition of "Diet Books We Read So You Don't Have To"... oh boy oh boy. Dr. Steven Gundry's "The Plant Paradox" talks all about why fruits, vegetables, beans and legumes, and whole grains are killing us all.... and we talk about why Dr. Steven Gundry's book is full of sh*t. Emily takes over this book review and diet plan that is sure to leave you mind...
Optavia 14.03.2022 46:32
Why eat food when you can spend more money for packaged "scientifically designed fuelings" instead?! Today we take a deep dive into Optavia, and what we found was not good. We'd recommend you just stick with food. Today's BS PS is all about protein: how much should we eat, is it overrated, and what to think about when choosing protein foods and supplements. Visit rdsvsbs.com a...
Lumen 07.03.2022 44:21
A device that can "measure your metabolism" and encourages you when you're "burning fat"? Yea.. we're baffled/infuriated too. In this episode, we discuss (aka rant about) the company Lumen and all the problems that pushing "fat burning metabolism" can cause. A warning: we get headed and Marie drops a couple of f-bombs. Visit rdsvsbs.com and check out the bl...
Red Meat and Cancer 28.02.2022 39:12
In 2015, the media went WILD after a report from the World Health Organization classified both red meat and processed meat as things linked to cancer. In this episode, we take a look at what the numbers published ACTUALLY mean (spoiler: it's not as earth shattering as the media would make you believe), and whether or not these classifications mean you should cut red meat and processed meats o...
Paleo Diet 14.02.2022 48:22
On the surface, the paleo diet seems harmless, right? Getting back to our human roots, eating only foods we at 10,000+ years ago to really get back to what makes us human. So what do dietitians think of this diet? Once peeling back the layers of this onion of a diet, we starting to notice some glaring issues with diet and its truthfulness of being the diet of our Paleolithic ancestors. BS PS is al...
Hydroxycut 07.02.2022 42:53
If ever there was a product we had to take down, it would be the miracle-weight-loss-pill hydroxycut. By now, our listeners know there is simply no one pill you can take for magic weight loss, but let's take a look at what is actually in these pills. Spoiler: it's bad, and kind of scary! BS PS looks into what to look for on labels of sports drinks, and what marketing gimmicks to avoid. ...
Calibrate 31.01.2022 49:51
You may have noticed a recent ad campaign promoting the newest weight loss program called Calibrate. This company promises to use biology in YOUR favor with a combination of lifestyle changes and medication. We take a look at the nutrition advice promoted and the medication prescribed. Is the program really the weight loss miracle it claims? BS PS discusses officially and colloquial definitions of...

Mark Hyman MD's "Eat Fat, Get Thin" Book Review, Pt 2 17.01.2022 55:36

Mark Hyman, MD's "Eat Fat, Get Thin" Book Review, Pt 1 10.01.2022 58:16
On today's episode, we review the first half of the book "Eat Fat, Get Thin" (cue eye roll of the title) by Mark Hyman, MD. This low carb advocate (but also simultaneously "plant based foods", which are carbs, advocate), takes us through a convoluted web of seemingly conflicting ideologies and ideas around metabolism, weight, and health. We read this book so you don't...

Gluten 29.11.2021 44:41
Gluten - we're all avoiding it in the name of health, but do most people even know what it is? In this episode, we talk about what gluten is, what it does in the food and in the body, and who, if anybody, should be avoiding it. But don't worry, this episode is certified gluten-free!

WW (Weight Watchers) 22.11.2021 50:49
We've probably all heard of WW (the diet program previously known as Weight Watchers). But what is a dietitian's take on this program?

Whole 30 19.07.2021 52:14
