The Bone Broth Diet - 21 Day Plan

With its invaluable health benefits and body healing powers, bone broth is a superfood craze that’s here to stay — and this 21-day bone broth diet plan can help you get the most out of it. Following a bone broth diet can lead to increased energy, brighter skin, sustainable weight loss, and improved digestion.

Here’s the rundown on why bone broth is so good for you, and how to follow a bone broth diet that will improve your health in more ways than one.

Benefits of Bone Broth

Bone broth is the only true dietary source of type II collagen, which gives it a unique nutrient profile unlike that of any other food.

Bones and connective tissue are packed with the beneficial proteins collagen and gelatin, which are known for enhancing the appearance of skin. But a lesser known fact about collagen is that it also works on the digestive system by repairing the gut lining. This can help improve chronic digestive issues and autoimmune conditions that stem from leaky gut syndrome.

Collagen is also rich in the anti-inflammatory amino acids glucosamine, proline and glycine, which help ease joint pain, repair cartilage, and maintain lean muscle mass. If you’ve ever seen a thick layer of gel formed on top of refrigerated bone broth, that’s the collagen that has been released from the bones. (It’s also a sign of a highly nutritious broth!)

Bones are also storehouses for certain essential vitamins and minerals that we don’t get nearly enough of in our diets today — such as calcium and magnesium — which promote restful sleep and help reduce stress. (We could all use a little more of that, huh?)

Simmering bones and connective tissue into a broth for 10 to 16 hours enhances the digestibility of these powerful nutrients, and makes them incredibly easy for our body to digest, absorb, and assimilate. The easy digestibility of bone broth is why it’s one of the top recommended foods for those with weakened or compromised digestive systems, and others who may have trouble properly absorbing a nutritional supplement.

NEED A QUICK EXPLANATION ON WHAT EXACTLY IS BONE BROTH?

Watch as Celebrity Health Trainer, Thomas DeLauer breaks down the ins and outs of what bone broth really is. In just two minutes, he’ll talk about what bone broth is and what it can do for your gut, joint, and skin health.

What Is the Bone Broth Diet?

The bone broth diet (popularized by Dr. Kellyann Petrucci) is a 21-day plan that involves eating Paleo for five days and fasting for two. During the five days of eating Paleo, you drink anywhere from one to three cups of bone broth. On the fasting days, you have three to six cups of bone broth. It’s basically the Paleo diet meets intermittent fasting, combined with an increased daily intake of bone broth.

Many people find that following a Paleo diet helps improve symptoms of autoimmune conditions, reduces inflammation, and supports gut health and weight loss. This is because the Paleo diet cuts out the foods that are most problematic — such as grains, refined sugar, and legumes — and replaces them with high-quality animal proteins and vegetables, as well as small amounts of fruits and healthy fats from nuts and seeds. The bone broth diet takes Paleo to the next level by adding in two days of intermittent fasting.

Intermittent fasting is a cornerstone of many popular diets today, such as the keto diet, the 5:2 diet, and the crescendo fasting method. Intermittent fasting has been shown to help burn fat more efficiently, speed up metabolism, increase lean muscle mass, improve energy levels, reduce inflammation, and sharpen mental focus. When you combine bone broth with fasting, you get even more complementary nutrients that support your body’s natural healing, repair, and regeneration processes.

It’s important to make sure that whichever bone broth you use for the bone broth diet is sourced from bones of grass-fed cattle or organic chicken bones. The bone broth also should primarily use the neck, feet, and femur bones and tissues. These parts are the richest in collagen, while grass-fed or pasture-raised animals are richer in anti-inflammatory nutrients. In other words: the healthier the animal, the more nutritious the broth.

Sample Schedule

Meals Eating Day (5 days per week for 15 days in total) Bone Broth Fasting Day (2 days per week for 6 days in total)
Breakfast Feisty Kale Breakfast Frittata 1 cup bone broth
Snack 1 cup bone broth 1 cup bone broth
Lunch Shrimp, Avocado, Mango and Fennel Salad 1 cup bone broth
Snack 1 cup bone broth 1 cup bone broth
Dinner Grilled Pineapple Chicken 1 cup bone broth
Snack 1 cup bone broth >1 cup bone broth

Note: On fasting days, drink unlimited liquids throughout the day, such as water and herbal tea.

The bone broth diet isn’t meant to be complicated or hard to stick to. The basic idea is that you:

  • Eat Paleo for 21 days.
  • Drink one to three cups of bone broth on your eating days.
  • Only drink bone broth two days per week (between three to six cups), as well as plenty of fluids.
  • Substitute snacks for bone broth on eating days.
  • Don't eat any sweets or desserts (even Paleo-friendly ones).

Bone Broth Diet FAQ’s

Will I Be Hungry During the Bone Broth Diet?

Bone broth contains approximately six to 10 grams of protein per cup, which means fasting on the bone broth diet will still provide you with 18 to 32 grams of protein to fill you up. If this is your first time practicing intermittent fasting, there may be a small adjustment period as your body gets used to taking in fewer calories, but you shouldn’t feel starved. When you do get hungry, have another cup of bone broth, herbal tea, and/or water.

Do the Fasting Days Have to Be Consecutive or Can They Be Apart?

You can pick any days you want for your bone broth fasting days. Just be sure to separate your two mini-fasting days with at least one or two non-fasting days.

Is the Bone Broth Diet Safe for People Who Have Blood Sugar Problems?

Intermittent fasting, the Paleo diet and bone broth are all recommended for improving insulin sensitivity, which means it’s generally safe for people who have blood sugar imbalances like type 2 diabetes. (However, it’s always important to check with your doctor before starting a new eating plan.)Since you’ll also be taking in anywhere from 18 to 32 grams of protein from bone broth on fasting days, you’re less likely to have intense blood sugar fluctuations or struggle with low energy.

Is There a Difference Between Bone Broth and Regular Broth or Stock?

Yes, there is a difference. And it’s important to note this for the bone broth diet, otherwise you won’t experience all of the amazing health benefits!

On the simplest level, regular broth isn’t simmered with bones for an extended period of time, so it won’t contain the collagen and gelatin that gives bone broth such incredible health benefits. To clear up the confusion, we’ve created an entire post on the blog that explains all of the differences between bone broth and regular broth or stock.

Most importantly, you must use true bone broth sourced from grass-fed or pasture-raised animals on the bone broth diet.

Who Can Benefit From the Bone Broth Diet?

Nearly everyone can benefit from the bone broth diet. You may find the bone broth diet especially helpful if you:

  • Struggle with skin issues, such as acne, eczema, or arthritis
  • Have joint pain, or a joint condition, such as osteoarthritis
  • Are recovering from a bone or tissue injury
  • Suffer from digestive symptoms, IBS, IBD, or leaky gut syndrome
  • Have been diagnosed with an autoimmune condition
  • Get frequent colds or flus
  • Struggle with low energy

Is There Anyone Who Shouldn’t Follow the Bone Broth Diet?

As with any dietary change, it’s important to check with your doctor or licensed healthcare practitioner before jumping into the bone broth diet.

While the bone broth diet is generally safe for most adults over 21, fasting should be avoided if you’re pregnant or nursing. In this case, you can still consume bone broth (and even feed it to your children and pets), but it should be consumed as part of a diet that’s rich in plenty of whole, unprocessed foods.

Does it Matter if I Use Chicken or Beef Bone Broth on the Bone Broth Diet? Can I Use Both?

No, you can use either one and still get the same benefits!
