When Hack Your Well being: The Secrets and techniques of the Intestine got here out, I knew I needed to evaluation it. As a lot as I can’t stand Netflix diet documentaries, I do know everybody desires to learn a synopsis and my ideas about these often-sensationalized films.

In contrast to a few of the Netflix documentaries, I discovered this one was comparatively nicely accomplished and I agree with the take-away messages they shared.

However it isn’t with out some criticism. Let’s dive in.

Intestine well being has been a preferred space of analysis for the previous couple of years, and we’re simply beginning to scratch the floor of what the well being of our intestine means to our general well being. Power well being circumstances reminiscent of kind II diabetes, weight problems, irritable bowel syndrome, arthritis, sleep problems, melancholy and nervousness have all been related with poor intestine well being, however we aren’t positive of the precise mechanisms by which they’re linked. 

As Tim Spector, a genetic epidemiologist from King’s School in London says within the movie, “That is new science, the tip of the iceberg. There’s one other 97% extra to find.”

That is true: we’ve restricted human analysis, particularly on people. Hold that in thoughts.

The Netflix Hack Your Well being Stars:

Maya is a pastry chef with orthorexia who has a restricted weight-reduction plan. She’s even afraid to eat her personal meals. She eats largely greens after which dietary supplements her weight-reduction plan with “potions and powders,” and finds the wellness business very complicated. I believe lots of people can relate to that.

Daniell is a doctoral scholar with continual intestine ache. She started to undergo after consuming unhealthily throughout her undergraduate years. She has taken many rounds of antibiotics to assist her signs, however with no impact. She now associates consuming with nervousness, ache, and discomfort and might solely eat 10-15 meals.

Kimmie is a single mother struggling to drop pounds. She wonders if her intestine well being is why she has not been as profitable as different individuals in shedding weight. 

Kobi is a retired aggressive eater who has eaten over 10,000 hotdogs. He can not really feel any starvation or fullness cues, and might go days with out consuming. He’s apprehensive that his profession has broken his intestine past restore. 

These individuals all did at-home gut-testing through which their poop was analyzed to see what kind of micro organism it contained. They used a intestine well being check known as Floré that’s accessible on-line for $299USD. As per the web site, the makers of this product state: 

“Our intestine well being check can detect over 23,000 microbes in your intestine, together with micro organism, fungus, yeast, parasites, and viruses. With using entire genome sequencing expertise, we are able to detect these all the way down to the pressure stage and the relative abundance of every microbe. Use your report to find out which meals and dietary supplements are greatest for you or improve to our Precision Probiotics to your customized intestine well being resolution.”

Proper. There’s the gross sales pitch, full with an upsell. Crimson flag.

Tim Spector is likely one of the specialists reviewing the outcomes with the individuals within the movie and seems to be slightly supportive of those assessments (in all probability as a result of he sells them too – see my evaluation of Zoe right here). His perception is that these assessments may help us determine particular meals we should always and shouldn’t eat primarily based on our intestine microbiome. 

Dr. Guilia Enders, writer of the guide Intestine: The Inside Story of Our Physique’s Most Underrated Organ, says that these assessments are not more than a enjoyable experiment. She finds them pointless, and says you can don’t want assessments to deal with your intestine higher. Bettering our weight-reduction plan (we’ll discuss that in a minute) is what most individuals really need, not microbiome testing.  

I 100% agree together with her, and for this reason: at this level, we don’t know what the optimum gut-microbiome seems like. Figuring out that, what are the outcomes of those assessments being in comparison with? These assessments additionally solely analyze your intestine micro organism at a single cut-off date, and we all know that our intestine can change shortly primarily based on what we eat, stress, antibiotics, and the atmosphere. 

A microbiome check that, for instance, tells me to not eat apples, sausages, and cake, is mainly pulling this out of skinny air. Do we all know that the Customary American Weight loss plan seems to have a destructive affect on our intestine microbiome? Sure. Does this imply I ought to by no means eat sausages or cake? In fact not.

And upselling dietary supplements for a ‘customized intestine well being resolution’? Have they got a billion totally different probiotics to swimsuit the microbiome of each single one that takes the check?

That’s 100% advertising spin. Don’t purchase into it. Most individuals don’t even want probiotics (I wrote about that right here).

I want we as a society may deal with the BASICS – that’s, enhancing the standard of our diets as a complete, eliminating suggestions that drill diets all the way down to single meals, and simply consuming sufficient crops, which solely round 1 out of 10 of us really do. That’s what can really assist our microbiome.

Why do we have to hack all the things and check ourselves for data that’s mainly ineffective?

I requested Leigh Merotto RD, a intestine well being dietitian in Toronto, for her ideas on these assessments. She had this to say:

“Consultants agree {that a} wholesome intestine microbiome ought to have a variety of microbes and species, however what these numbers seem like, will not be but outlined. The truth that these assessments declare to diagnose “wholesome” quantities of micro organism, is only primarily based on their very own parameters which is, for my part, unethical. Additional, viewing the corporate’s web site, they promote dietary supplements to handle totally different “issues” their check can diagnose, so it’s all the time a pink flag for me to be cautious when an organization seeks to inform you that you’ve an issue, and promote you an answer to repair it.”

Again to Kimmi. When the specialists checked out her check outcomes, they discovered that she had a much less numerous microbiome, and no Prevotella micro organism. This seems to be the same discovering in others who’ve a tough time shedding weight. 

The specialists inspired Kimmi to deal with sustainable weight-reduction plan adjustments and to extend fruit and veggies to assist her enhance her intestine well being. This highlights that we are able to’t really do a lot with the outcomes of those stool assessments. Merotto provides, “whereas it was clear within the documentary that these assessments can present sure ranges of useful micro organism being “low”, they didn’t have any scientific suggestions to handle these ranges, apart from to eat a extra plant-diverse weight-reduction plan. We don’t want them to shell out 100’s of {dollars} on a stool check to inform them that they want to try this.”


We additionally don’t know at this level how a lot of an affect a selected kind of micro organism can have on the power to drop pounds. Weight problems is a multifactorial continual sickness and whereas intestine well being could play a task, there are such a lot of different elements to contemplate. 

Hack Your Well being: Analysis.

The movie attracts on analysis by Dr. Jeffrey Gordon, a researcher from the Washington College College of Medication in St. Louis. In a 2008 research, he transplanted intestine micro organism from equivalent twins the place one was overweight and the opposite was lean, into mice. The mice that obtained the micro organism from the overweight twin gained extra weight on the identical meals in comparison with the mice that obtained micro organism from the lean twin. 

Whereas that is undoubtedly an fascinating consequence, it doesn’t inform us a lot about free-living people in the true world. 

Additionally they drew on comparable analysis on psychological well being which discovered that when mice got micro organism from an individual with melancholy, the mice began to point out comparable signs and there have been adjustments in serotonin ranges within the intestine and mind.  I’m not doubting the gut-brain connection and we all know that the majority of our serotonin is produced within the intestine, however once more, we are able to’t make any particular conclusions on people from this analysis. 

fiber and gut healthfiber and gut health

Most significantly, what suggestions can we give to people, primarily based on these research? Melancholy and the intestine is an interesting matter, nevertheless it’s essential to not ignore reverse causation. Does a poor weight-reduction plan give individuals melancholy resulting from altering their intestine micro organism, or does their melancholy result in a poor weight-reduction plan and altered intestine micro organism? It’s laborious to say, and it might not be the identical reply for everybody.

Kobi’s stool check discovered that he had fairly good intestine micro organism which they thought could possibly be associated to his conventional Japanese weight-reduction plan. He additionally did a mind scan and primarily based on the outcomes, they thought that a few of his points had been associated to the truth that his mind is used to him being a aggressive eater.

Somewhat than giving him something radical to do, Dr. Enders suggests he attempt to take heed to his physique and honor all his senses when consuming. Whereas Kobi’s case is excessive, making an attempt to get extra in tune with starvation and satiety alerts is one thing many individuals can profit from. I agree with Dr. Enders right here, though for individuals who grew up being instructed to wash their plate, or who’re continual dieters, making an attempt to reconnect together with your physique’s cues is a course of. It could appear easy, nevertheless it’s not straightforward, and it takes time.

Fecal Transplants

Let’s get into fecal microbial transplants, or FMTs, which is the place another person’s poop is put into an contaminated affected person. This therapy is permitted by the FDA to be used in just one sickness: C. Difficile. This situation is when micro organism inflames the colon and causes horrible diarrhea to the purpose of being probably deadly. Analysis is ongoing to see if FMTs may help in different diseases, however once more, there are nonetheless quite a lot of unknowns.

Regardless that it has not been permitted, we be taught that Daniell has been making an attempt FMTs and obtained feces from each her brother and boyfriend. We see her transferring poop from her fridge into check tubes to be became poop capsules. When she received feces from her brother, she had some enhancements in her signs, however she discovered that she additionally received his pimples issues. She then switched to her boyfriend’s, and located the pimples went away. Nonetheless, her boyfriend has psychological well being points, and as soon as she began to make use of him as a donor, her melancholy was exacerbated. 

This seems like a dumpster hearth, to be trustworthy. Whereas there’s some preliminary analysis that means that melancholy and nervousness could consequence from (or be alleviated by) FMT, this anecdote served as much as us by the movie is simply that…an anecdote.

If you get the nice micro organism from somebody in an FMT, you additionally get the dangerous. There are additionally enormous dangers to randomly inserting another person’s poop into your physique, so please: don’t do this at residence. 

When Maya’s intestine well being check was reviewed, they discovered that she had a fairly “wholesome” microbiome which is probably going resulting from all of the greens she eats. They reminded her that whereas consuming a kale salad every day is nice, it’s not sufficient and inspired extra variety together with her meals. We then see her specializing in including potato chips again into her weight-reduction plan. 

For somebody affected by orthorexia, including potato chips into their weight-reduction plan is a big step. It could have been nice if they’d additionally given her some particular examples of different plant-based meals to devour that will contribute to bacterial variety, reminiscent of entire grains, fruits, legumes, nuts, and seeds, however maybe they didn’t wish to irritate the state of affairs. I believe there’s much more to the story than we’re seeing right here.

It isn’t unusual for individuals with continual intestine points and histories of consuming problems to have worry and nervousness round meals. That is the place working immediately with a dietitian may be useful. A dietitian may help you slowly add meals again to your weight-reduction plan and monitor signs.

Netflix Hack Your Well being Evaluation: In Brief.

In comparison with different Netflix diet documentaries Hack Your Well being was pretty nicely accomplished. The specialists had been clear that we’ve much more to be taught in regards to the gut-microbiome, which is an effective overarching message. So is the advice to eat a weight-reduction plan wealthy in entire, plant-based meals and goal for 20-30 various kinds of crops every week to assist promote a wholesome gut-microbiome. 

Together with fermented meals can also be useful as nicely.

Nothing about this film is a ‘hack.’ Complete meals, extra crops, and sustainable adjustments have been promoted by dietitians for years. Strong recommendation.
