Four-Day Bone Broth Fast… Say whaaat?!

If you read my last post you know that I have recently committed to starting the Gut Thrive in Five gut/microbiome rejuvenation program, and may have picked up on the fact that I’m kicking off the program with a four-day-long bone broth fast.

Yes, you most likely interpreted that correctly. I have been consuming almost exclusively bone broth the past three & a half days. Which means I’m 87.5% of the way through, according to my handy dandy MacBook calculator. I’m so close to being done I can smell the victory! (AND just about every other food substance currently within a two-mile radius…)

But I’m sure you’re wondering the methodology and reasoning behind this crazy bone broth fast so I’ll briefly explain.

A traditional bone broth fast entails consuming exclusively bone broth with some high-quality sea salt added for a set duration of time in order to starve down all sugar-producing gut bacteria – both good and bad. The purpose being to rebalance your gut microbiome, getting rid of the sugar-producing pathogens and later re-inoculating your gut with the beneficial bacteria (aka probiotics).

In the Gut Thrive version of a bone broth fast you are able to consume a bit more than just bone broth. And by a bit, I mean a bit. But thank the lord for those bits, because they have seriously saved me over the last few days.

The Gut Thrive Bone Broth Fast includes:

  • Bone Broth – homemade from chicken and/or beef bones
  • Collagen protein powder* – 100% pure collagen protein or peptides (I like this brand)
  • Gelatin protein powder* – again, 100% pure gelatin protein (I like this brand)
  • Coconut Oil* – high quality, unrefined
  • Sea Salt* (Himalayan, Celtic, or a mix of the two)
  • Dried Spices & Herbs* (cumin, cilantro, oregano, fennel, rosemary, etc.)
  • Lemon juice (not from concentrate, in your water)
  • Green juice (made fresh or store-bought, cold pressed varieties, made with just green veggies, and a bit of green apple if you must)
  • Herbal teas

* The best way to consume these is blended or mixed into your broth, to add some extra protein and healthy fat, and make the drink more palatable/appealing. (Refer to my “Immunity in a Cup” recipe for more on how to do this!)


Bone broth is an incredibly therapeutic food and is now being more widely recognized for its multitude of health benefits. These include including helping to soothe and heal the lining of the intestines, improving joint health, boosting the immune system, and aiding/enhancing digestion. The reason why bone broths are so nutrient-dense and healing is because simmering down [high-quality, clean-sourced] animals bones releases a wide variety of compounds such collagen, gelatin, and the amino acids proline, glycine, and glutamine, along with easily absorbed minerals such as calcium, magnesium, phosphorous, silicon, and sulphur.

I like to think of bone broth as a protein-rich liquid multivitamin.

For these reasons, fasting on bone broth is not only entirely safe, but also incredibly nourishing. By drinking bone broth combined with collagen and/or gelatin protein and sea salt (sodium) you provide your body with plenty of protein to keep your metabolism going and essential minerals to keep feeding the vital organs of your adrenals and thyroid.

You also give your digestive system a bit of a break, which allows your body to focus on healing your gut (rather than using it) and regenerating its cells using collagen and glutamine.

If you want to learn more about a bone broth fast here are some of the best resources I’ve found that I used to further educate myself beyond what was explained by Christa in one of the Gut Thrive videos:

And since there isn’t a whole lot out there on the subject, tomorrow I’m going to write a post detailing my individual experience with the fast so that you have a little insight into what it looks (and feels) like.

    Are you not concerned about the high amount of lead in bone broth??

  • Marge

    You will be when you start getting dementia.

  • Laura

    Shannon, I wouldn’t be either.. first of all, the lead is probably coming from the highly lead toxicated water we have here in the USA, not the chicken bones. Therefore Marge, if you live in the States you are being exposed to just as much lead as Shannon is but not receiving the same benefits by not drinking bone broth. Secondly you consume cilantro and see song with charcoal bit like Christa talks about then you’ll be fine you’ll be constantly pulling those metals out

    • Shannon

      Thank you, Laura. Love to you & your knowledge!

      • Marge

        Watch the video link. There is more lead in the bone broth than the water. Why take a chance? There is plenty of nutrition in other foods, greens, so why take the chance when you don’t need to. But to each there own.

  • Marie

    Bone broth fast is really effective! Right now I’m doing it by drinking Au Bon Broth and I’m already seeing the results.

    • Shannon

      Yay! Wonderful. I know it helped me a ton!

  • Lisa Light

    I am on my first day of my 3 day bone broth fast. I bought beef and chicken bones from a butcher that butchers only grass fed animals. The beef bone broth is really tasty. I’m going to add a bit of coconut oil in my next cup.

    I read the previous comments about lead. Really? I don’t see how. Tons of more toxins in all the soaps, cleaners, personal care products, makeup and for sure water.

      How did it go, Lisa? Would love to hear about your experience!
