My 5 Days on the Fasting Mimicking Diet

By Leigh Wagner, PhD, MS, RDN

If you follow me on Instagram, you may have seen that I did my second round on the fasting mimicking diet this past week, after doing it for the first time last November. I gave a few quick glimpses of it in my instagram stories but wanted to do a deeper dive into the program here. 

First, I want to give you the background and make it clear this is not a sponsored blog post (#ipaidforthis). I want to share with you the science behind the program, what it is, and who should and shouldn’t follow it. 

Three reasons why I did a second round:

  1. I wanted to see what a second round felt like compared to the first one.

  2. I like to try things that I ask clients to try so I have personal experience and empathy for the process.

  3. To be honest, I just turned 35 and I want some of those anti-aging benefits that I’m supposed to get from fasting (fingers crossed). 

So, let’s get started. 

What is the fasting mimicking diet (FMD)? 

Dr. Valter Longo - a PhD researcher at USC who has studied longevity for 30+ years - designed the fasting mimicking diet based on his (and others’) research to provide the benefits of fasting without having to completely stop eating. L-Nutra is the company he started and ProLon is the 5-day (FMD) program he designed, studied and eventually made available to the public. I provide an overview of the diet below. 

How was the fasting mimicking diet created?

Dr. Longo (per his book) created the FMD based on 5 pillars of the “Longevity Diet,” which (as far as I can tell) are the dietary principles of the FMD. This is the scientific/evidence-based foundation upon which the FMD stands:

  1. Basic research and juventology, which is the study of what keeps people young.

  2. Epidemiological studies, or studies focused on certain populations of people.

  3. Clinical studies: Studies testing an intervention like a diet or drug to see if it’s safe and effective. This would encompass the lauded “double blind placebo-controlled trial.”

  4. Centenarian studies, which are studies on people who live high quality, high functioning lives until they’re 100 years and older.

  5. In his words, “the study of complex systems.” He describes this as taking an “engineering approach” to characterize how our complex human body (system) can be reduced down to a model to help understand the interactions between food, cellular function/damage, and longevity and aging.

Before I go further, I want to clarify some important groundwork. I like to visualize his work and diet like a pyramid. At the base of the pyramid are these 5 pillars. Out of his in-depth research, he was able to characterize a dietary pattern for longevity. So, atop this 5-pillar foundation are general dietary characteristics of his “longevity diet” (summarized below). Finally, at the peak of the pyramid is the carefully formulated 5-day “fasting mimicking diet” that are the specific foods of his studied “intervention.”

What are the potential benefits of fasting?

The physiological benefits of fasting include anti-aging (and even anti-cancer) activity by turning on a process in the body called “autophagy,” which triggers the body to “clean up.” In this process, our cells remove damaged contents so they can be metabolized and excreted from the body. 

Autophagy is a natural way to get pathogens and abnormal contents in cells out of the body. You can find more background on autophagy at PubMed and Healthline. Autophagy provides anti-aging benefits and potentially even some anti-cancer benefits, because when cells act abnormally and replicate in an uncontrolled manner, that’s essentially how cancer develops. Autophagy removes these abnormal or damaged cells before they get out of hand. 

So, fasting turns on autophagy and the fasting mimicking diet seeks to engage that process without having to stop eating completely. In short, you still eat food but calories are limited (800-1100 calories per day), and in theory you may still get the benefits of fasting.

Overview of the Longevity Diet Principles and the Fasting Mimicking Diet:

As I mentioned, Dr. Longo based his very specific FMD on the principles of what he calls the “Longevity Diet.” The general gist is that it’s very low protein, high complex carbohydrate, and moderate intake of high quality fats and oils. Here are the basic principles on which he bases the FMD:

  • Mostly vegan/plant based: High intake of whole grains, vegetables, root vegetables, beans.

  • Protein sources are mostly plant based: Beans, seeds, nuts, infrequent animal protein, fish or seafood.

  • Small amounts of fish, seafood and mollusks: These are some of the most nutrient-dense foods on the planet, not to mention they contain essential omega 3 fatty acids that our bodies cannot make, so we have to eat them.

  • Rarely animal protein/meat and small amounts of dairy: Mostly sheep or goat’s dairy.

  • Naturally low in saturated fats because you’re eating primarily plants.

  • Eat like your ancestors when possible.  

Unlike his above-described Longevity Diet, which is more of a lifelong eating style that he suggests most people adopt most of the time, the fasting mimicking diet is a very specific, calculated 5-day program (a kit of packaged food) that emulates the principles of his Longevity Diet above. You can get more details in his book, but I’ll give an overview of his 5-day FMD here:

  • Day 1 (transition day): About half the food is complex carbohydrates and healthy fats (remember, low protein) in the form of packaged bars, soups and olives. You take a couple supplements (omega 3 and multivitamin). You have a few options for tea and can drink as much water as you want.

  • Days 2-5 (noticeably less food): The same balance of complex carbs and fats and tea or water to drink. These 4 days you also drink a glycerol concentrate combined with water. In an interview with Dr. Longo, he explained the inclusion of glycerol was due to their discovery that glycerol is elevated in the body during fasting, and he also suspects glycerol may have to do with why the body doesn’t breakdown muscle during fasting. 

Can I create my own DIY fasting mimicking diet? 

Dr. Longo summarizes the general principles of the FMD in his book but encourages people to use his specific diet. I’m sure that’s partially because he designed his exact plan very intentionally to meet his guidelines and also because – at least in part – money, right? 

So, yes, you could make a calorie-restricted, plant based, very low protein, high quality fat diet that you follow for five days. You can actually get a free copy of his book to see what his guidelines are for this and create recipes based on that. 

Who might benefit from FMD?

First off, I want to advise that if you’re considering the FMD or any other version of fasting, you should consult with your healthcare provider(s) to ensure you’re healthy enough to do so. Ok, so Dr. Longo would likely suggest that most of us could benefit from some form of fasting and certainly the FMD. I would agree that most of us would do well to give our bodies a break through FMD or a monitored fast. 

I love that, historically, fasting has been a part of many religions and cultures. Also, humans have naturally gone through seasons of plentiful food (i.e. fall harvest) and famine (late winter). Our bodies have adapted to these seasonal variations in food intake. 

For my clients, some of the best results have come from clients who have cardiometabolic (pre-diabetic and/or cardiovascular) disease risk factors. It is also easy because the program is clear and simple; everything you need is in a box. I know Dr. Longo is working on finalizing FMDs specifically for autoimmune disease and other conditions, but those aren’t yet available. I’ll be curious to test them when they are released.

My own experience with the FMD

Read on below for a bit about my own experience with FMD, what the food is like, how I felt, and all those soups.

Fasting Mimicking: Days 1-3 

The food and drink: It’s prepackaged food, but for prepackaged food, it’s pretty good. For breakfast you eat a nut/granola-type bar, which is small but good. 

Lunch and dinners are always soups and sometimes olives and/or flax crackers. At the end of a couple days you get some kind of weird chocolate thing with inulin in it, which I called the “fart bar.” The inulin is a prebiotic (fiber), which keeps the digestive tract moving along, but bloated me something fierce.  

On days 2-5, you start drinking the proprietary glycerol concentrate with water. I put mine in the bottle they provided and added the bags of hibiscus tea to steep throughout the day. I found an interview with Dr. Longo where he says that the glycerol (which is the backbone of triglycerides - a type of fat) is elevated in people who are fasting and may be the reason that muscle is spared (very little to no muscle loss) during periodic fasting. 

Supplements: They give you an omega 3 algae supplement and a multivitamin, which were fine, although I wouldn’t have put folic acid in the multi, but that’s a blog post for another day

Energy/hunger: The first time I did this last November (2018), I felt fine, at least on days 1-4. I couldn’t believe how well I transitioned into the fast. I didn’t notice any blood sugar crashes or hangry moments. 

This second round, I had more headaches because I stopped caffeine (coffee), after day 1 because caffeine can kick you out of fasting. By days 4 and 5, I was clear headed and felt really good. 

Mindset/food obsession: The first time around, I was really busy on days 1 and 2. I saw clients all day each day and had some evening activities, so I didn’t have much time to think about it, which helped. The second time, I made more intentional effort to keep busy and check a few things off my to-do list I had been putting off. I also asked for some personal cheerleading from friends.

One other random thing: I had some really vivid dreams and slept very deeply for the first 3 nights.

Fasting Mimicking: Days 4-5

The food/drink/supplements: Same bars, soup, crackers/olives. Some of these meals are even more sparse (just soup), and I would eat like small spoonfuls to draw out the meal longer than 90 seconds. The first round, I enjoyed the food. Round 2, I couldn’t look at another spoonful of soup. Maybe the novelty wore off?

Hunger: Round 1 (last fall): I found myself talking a lot about food by this point. Upon reflection, it was interesting because I hadn’t been that obsessed with food since I was deep in my disordered eating. My husband, Rob, would tell you that I was talking about food a lot. Round 2 (last week): I was okay, but more just wanting to quit and eat real food. I didn’t feel like I was obsessing about food the way I was during round 1. 

Both rounds I was ready to quit on Day 4. I’m laughing because both times I was texting with my friend and colleague Amy who’s done FMD and had a good experience (herself and with her clients). I told her that I was going to quit and would maybe finish a day early. She encouraged me to keep going. She reminded me that the program was designed to mimic fasting and was an evidence-based approach to facilitate autophagy, which is basically the body cleaning up dead cells. She also reminded me that I’ve done other harder things in my life. So, thanks to Amy, I made it through day 5. 

Energy/temperature: The fifth and final day, I remember wearing an extra layer of clothes because I was cold during round 1 (during the fall/winter). And I cut my typical walking route with my dog short because I didn’t have the energy.

Round 2, it was a hot week in September, so I haven’t noticed temp changes as much as last fall. 

Day 6 “Refeeding” Day: They tell you to start by drinking liquids like broths and juices, which went well. Round 1: I tried some sweet potato and venison chili Rob had made a couple days before for lunch, and had a teeny bit of gurgling in my stomach, which was likely it waking up after several days. That evening I had some scallops and steamed broccoli and a glass of wine, which went straight to my head.

I was pleasantly surprised that my body adapted back to food so smoothly. I think one key is taking the morning slowly and not eating large amounts of foods or anything out of your typical norm of eating.

Round 2: I started transitioning a little bit on 5 day evening so that I would be able to eat mostly normally on Saturday. I’d say overall round 2 felt harder in some ways (sick of the food) and easier in other ways (kept myself busy and benefited from feeling clear headed and energized).

Final note: you must tolerate/like olives to do this. If you hate olives, you’ll likely be miserable because you eat them 4 out of the 5 days and sometimes twice a day!

Would I recommend the FMD?

Although I have done this two times and would likely do it again, maybe because I’m vain and want my skin to glow, and also because I want to live longer than my grandparents, I don’t think the fasting mimicking diet is for everyone. 

Some things to remember:

First, please make sure you have a healthy relationship with food if you are going to try the diet. 

Next, in terms of restrictions, this program should not be followed if you are pregnant, underweight, have low blood pressure, are generally “fragile” (Longo’s word), have diseases and/or are taking medications without first consulting with your doctor, people with diseases that inhibit their ability to make glucose (sugar) from protein, and athletes who are intensely training. 

Dr. Longo gives other warnings, but the best approach would be to work with a healthcare provider who is well-versed in the risks and benefits of the program. 

If you are already restricting caloric intake, then this may not provide the same benefits as someone who is eating a generally well-nourished, adequate caloric diet and then follows the FMD for only 5 days.

What the FMD is missing

As you can tell by its description, this is not a personalized nutrition program. If you’ve heard me speak, read my writing or followed me on instagram you know how important it is to get personalized nutrition advice. This program is a whole foods, evidence-based approach to fasting, but this boxed program is not able assess you and your individual needs. Remember, every single one of us has unique needs, not just at the biochemical or nutrient level but also from the perspective of our lifestyle, family and medical histories, emotional and mental health, cooking skill level, disease risk, metabolic health, genetics, financial health, stress, motivation, environmental and community support. The combination of all of these different needs within each individual make things a little more complex than a 5-day box of bars, packets of soup and a proprietary glycerol drink. Our nutritional needs are much more nuanced than that.

This program can never substitute for establishing a good relationship with a health care provider who can look at you, hear your story, assess your symptoms, measure your laboratory values and care about your wellbeing. As always, if you’re interested in working with me and live in the United States, you can request a discovery call

Learning to Cook and My Go-To Recipes and Cooking Websites

learn-to-cook-leigh.jpg

Cooking can be super intimidating. What does “sauté” mean? Blanch? Deglaze? Is a cube like a dice? What the heck is a pinch of salt? (it’s actually about 1/8 of a teaspoon so fill a 1/4 tsp half way)…

I remember when I was first learning to cook, how nervous I felt (my family is full of great cooks, so expectations run high). I burned, boiled-over, forgot, both under- and overcooked countless recipes, and every time I did, I learned.

How I learned to cook

When I teach cooking classes, I love to use the analogy of running: You (likely) wouldn't run a marathon by just thinking about it. You'd run a marathon by lacing up your shoes day-in and day-out to train, practice, and prepare yourself to cross the finish line.

It takes time, some discomfort and just plain work. 

Likewise, if you "can't" or "don't know how" or "didn't grow up learning how to" cook, then you probably aren't going to get any better by just thinking (*cough* dreading) it. 

How to get comfortable in the kitchen

Instead, here are some proactive ways to learn and prepare yourself to learn how to cook:

  • Look up how-tos (here’s one from Cook Smarts and one from Nourishing Meals). 

  • Find recipes online or pinterest. I’ll admit pinterest is one of my least favorite platforms because it overwhelms me, but they do have an endless number of recipes!

  • Set aside a day once a week or once a month to practice or try recipes.

  • Invite friends over to try out a couple recipes and send everyone home with meals for the week.

  • Also, whfoods.org have some very simple, basic healthy recipes and info about the health benefits of certain foods.

Here are come of my current go-to websites and blogs for recipes. I like these because I’ve cooked several of their recipes, and they work. Plus, they provide modifications for gluten-free, vegan, vegetarian, paleo, etc. You can often find what you need. I noted those that are strictly vegetarian recipes for anyone who’s already vegetarian to save you time:

My Journey: Thriving After Struggling with my Relationship with Food

leigh-wagner-my-journey.jpg

I can still picture sitting in class my senior year of college listening to my professor, Dr. Eunice Basler, display on the projector a description of “normal eating.”

I will never forget that class.

I was a lean (teetering on underweight) college athlete. An anxious perfectionist who mentally tabulated every bite I took from morning until night. I analyzed and re-analyzed exactly what I had eaten and what I would eat. I was so consumed with what I ate that I didn’t have much mental space outside of that and school to think about much else.

Needless to say, I wasn’t the life of the party.

I can hear my friends snort with laughter reading this. Who am I kidding?! I rarely even went to parties (ok, fine, I never did). I’d blame it on being an athlete, but the reality was that it was a combination of social social anxiety, perfectionism, and having some weird lack of FOMO in college. Who was I?!

My sophomore year of college I had actually changed my major from pre-business to nutrition because I found myself reading my friend’s nutrition textbooks.

I was obsessed.

My relationship with food

I’ll be the first to admit that I came to studying nutrition out of an unhealthy relationship with food. I was the teenage girl watching morning television at home during the summers and listening to the morning talk show hosts talk about calories and weight loss and the dangers of being overweight. In my mind, they were talking to me. I was determined to never be overweight, and I knew (from their talk show lessons) that I could avoid that by counting every calorie that did, would or ever could pass my lips.

So, that’s what I did. I lowered my fat and calories as much as I could while fueling enough to get through track practice. Looking back, it is so sad, but at the time, I thought I was being healthy. Well, for every fat gram I eliminated I steadily lost the same amount of my sense of humor, my love for being active, my ability to feel feelings. I was felt completely numb.

What is normal eating?

Fast forward a few years to that classroom with Dr. Basler, staring at Ellyn Satter’s definition of “normal eating.”

I read these words on the projector and had a sense of relief. Normal eating is being overly full sometimes. It’s also feeling hungry. It’s eating something that you don’t really love or stopping when you’re satisfied.

During that class, we were assigned to read the book “Intuitive Eating” by Resch and Tribole, and that was another level of exploration. I could eat anything and that was ok. I could trust my body to tell me what it needed. I could pay attention to foods I loved and also take note of foods that I just didn’t enjoy.

You’re probably like “umm… duh! This is the life of a veggie hater!” I know. But, from the perspective of a fragile, perfectionist college nutrition student, eating something that was not “healthy” (in the classic sense, at the time) was unfathomable.

I seriously remember one of the girls in my sorority (sorry, I think it’s weird to say “sister”) casually eating a piece of cheese like it was no big deal, and I was like “how can she do that? Doesn’t she realize how much fat is in that?!”

Wow, Leigh. You’ve got problems.

Yes, I really did. And, I can honestly say that the class I took with Eunice Basler (paired with finding an amazing therapist) saved my health (mentally and physically). After taking her class, I ate what I truly wanted to eat and what I actually enjoyed. This, however strange it might be to read, was a big deal for me.

This allowed me to regain my life. I started thinking about things outside of classwork, my track training schedule (technically field, I was a high jumper), and what I was going to eat.  

Intuitive eating and what is “normal”

Now, I can eat comfortably around others without anxiety. I don’t worry about calories, and I fully trust my body to tell me when I’m hungry or full and eat (or stop eating) accordingly. Sometimes I overeat (especially when my parents cook), and sometimes I undereat (especially when Rob and I haven’t planned). At times, I choose what to eat because it’s healthy, and other times (and now more often) I choose what to eat because it tastes good… healthy and tasty are definitely not mutually exclusive - check out my recipes. I, by no means, have a “perfect” relationship with food, and I never will. But, I know that I eat “normally,” and that’s what’s most important to me (and my mental health).

So, how did I get to this point?

Well, it’s taken a lot of time, hard work, appointments, honesty, reading, listening, and a wonderful support system of friends and family (seriously, I know how lucky I am). Here are some of my main self-help mechanisms:

  • Read the definition of “Normal Eating” by Ellyn Satter

  • Read Intuitive Eating by Evelyn Tribole and Elyse Resch

  • Sought counseling with a licensed therapist

  • Received massage therapy (it was helpful to develop a healthy relationship with my body and it continues to be an important part of my self-care)

  • Talked with friends and family I could trust about my struggle

  • Continued to read and listen to self help-type books. Some of them:

I remember one of the breakthrough moments of my progress after I had started therapy in college. It was after I finished jumping at a track meet where I jumped worse than I ever had, even in high school. My parents had come to the meet, and after changing out of my high jump shoes I went over to sit with my mom in the stands and I literally sobbed in her lap for a good 20-30 straight minutes. I remember thinking how relieved I was to actually feel feelings. That’s how numb I was. I remember when I finally laughed again, felt the feeling of being annoyed, and being grateful because I actually had feelings again.

Finding support for heathy eating

If you can relate to an unhealthy relationship with food, the bottom line is that you’re not alone, and I want to support you to get help. It’s definitely a journey without a final destination.

I’d never wish on anyone the struggle I’ve gone through (and I also know that many others have had a much harder and riskier journey than mine), but I’ll always be grateful for it. I would never be who I am today without it, and I know that I am better able to help my clients because of what I’ve gone through.

I realize that now most of my work as an integrative and functional medicine dietitian revolves around helping clients identify foods that cause inflammation and/or dietary problems to address chronic disease. Sometimes (often) this involves elimination diets - possibly the antithesis of intuitive eating?

So, this isn’t the end of the story, because our relationship with food is complicated.  I'll share the next chapter in another post, but it involves interviews and input from experts like Ellyn Satter, Evelyn Tribole and other experts who know a lot about how people develop healthy relationships with food and eating.

I’m excited to share more.

Misapplied Information is a Bigger Problem than Misinformation

Copy of Copy of Magnificence.png

To be completely honest, there’s a ton of really good information available to us. Yes, there’s click bait and spammy junk. But, you can also access pubmed abstracts and sometimes even full articles. Many of the most well respected schools and institutions provide free training and information online (Stanford, Mayo Clinic, Cleveland Clinic and others).

And although there’s some training involved in navigating through the nuance of scientific studies, what I’m more concerned about is the misapplication of good information.

What I mean is this: We see others close to us (friends, family members, people we stalk on Instagram) make diet, exercise or other lifestyle changes. We think: well, I like them, trust them, admire them and I want their results. I SHOULD DO WHAT THEY’RE DOING!

What we don’t realize is that their metabolism, genetics, health, family and life histories, and myriad other things are different than ours. We’re AREN’T THEM! And--news flash--that’s a GOOD thing. So, I’d say if you try a new way of eating and it just doesn’t quite feel right, what your body tells you are hints to you that maybe something isn’t quite right.

So, although there’s unending good information available to us now, we should check in with ourselves and honor what your body and intuition tells us. Is this right for ME or someone else?  

What’s the Magic Health Pill?

what's the magic health pill.JPG

My take on What the Health and The Magic Pill, two popular food and health documentaries

Over the past year, I’ve had people from all seasons of my life reach out to me and ask me what the H I think about the “What the Health” and “The Magic Pill” documentaries.

I have to be honest… I hadn’t even watched them. Although I’m obviously pretty interested in nutrition, health, and what we can do to reverse chronic disease, I sometimes need to just watch a binge-worthy documentary on Netflix (um… Wild Wild Country and Evil Genius anyone?!). I just need to shut off from all of that. Plus, I get to the point where I only need to watch 5 minutes of a documentary, see which “experts” they’ve interviewed, and I can already predict the bent to the show.

So, I finally bit the bullet. 

I picked these 2 out because they’re 2 of the most popular/high impact (people are making big health/diet decisions based on watching these), and they were both published in 2017. Other food and health-related documentaries I could have talked about include Fat Sick and Nearly Dead, Food Inc, Fed Up, Forks Over Knives, Cowspiracy, King Corn, That Sugar Film, and honestly more than I realized existed before watching each of these.

I had an intern working with me the past couple weeks, and we sat down to watch them (lucky her, right? Your assignment is to relax on my couch and watch movies with me). Together, we put this table (below) to compare and contrast the two documentaries. If you’re unlikely to read through the table, let me summarize it briefly here for you:

Ok, first before I go any further, I want to acknowledge that this is a very high level summary of what I see as the main themes, similarities and differences between the two documentaries. This is by no means comprehensive, and there is definite nuance to each.

So, now that we have that out of the way, here we go:

What the Health summary

What the Health (WTH) claims that a vegan, plant-based diet is the best health approach to eating. You should eat zero animal foods, and any chronic disease that comes from poor eating comes from foods derived from an animal. Sugar doesn’t matter. Eat all you want. You can see in the table that WTH is most concerned about processed animal products without concern for processed or refined carbohydrates. WTH would say that there is also no difference between organic or conventionally-raised foods.

The Magic Pill summary

The Magic Pill (TMP) claims that an ancestral “paleo” or ketogenic-type diet is the most healthful. Get back to the way we’ve historically eaten and let our genes lead the way. TMP would care more about highly processed/refined foods, overall. Quality of food is the higher priority over whether foods are animal or plant-derived.

Both documentaries hold big ag and big industry (pharmaceuticals and food) responsible for the cultural drive for this way of eating. They also both emphasize minimizing highly refined or processed foods (whether meat or carb). They both tell compelling stories of individuals who have dramatically changed their diet to follow the purported “best” way to eat, and you watch these people share how the diets have transformed their lives, leading to lower pain, less medication, and an overall better quality of life. Both documentaries tell compelling stories, and that’s what we all love. I can see why people choose to change their diets after watching either!

My take away: each of them emphasizes the importance of plant foods. Although they don’t address it in either movie we need to be mindful of the idea that you can eat a “healthy” version of either of these “diets,” and you can eat a less-healthy version (soda & chips are vegan and bacon & cheese are keto). So, using some common sense with their application is always important.

Is there a magic health pill?

So, What is the Magic Health Pill? I'm sure you can guess what I'll say, but there's no short cut to wellness. Eating more plants and less processed foods is always going to be a good way to approach your diet. The evidence is consistent in the literature that eating more plant foods is associated with better health outcomes. So, if you've never eaten your veggies, it's never too late to start.

I would say that if you’re unsure of what to do, just take a look at what you’re eating on a weekly basis (maybe keep a weekly log), and also pay close attention to how you're feeling. Do you have good energy, focus, good digestion? If not, your lifestyle may be playing a role in how you're feeling. As far as how you're eating, if half or more of what you eat is coming out of packages or windows (drive-thrus), then maybe a change would be worth it? If you’re eating mostly whole, minimally processed/refined foods, then you likely have a solid foundation. My only word of caution for the dietary approaches from each documentary is that they can both leave us vulnerable (similar to a Standard American Diet) to nutritional deficiencies if left unmonitored over a long period of time. There's no "one size fits all" approach to lifestyle changes, especially when it comes to diet. Integrative and functional healthcare practitioners are best equipped for monitoring and evaluating your nutritional status and would be a great sounding board for your efforts.

I know a really good nutritionist, if you’re looking for one.

So, what did you think about the documentaries? Have you made any changes since watching either or both of them?
