The 2 week bone broth diet has surged in popularity as a short-term wellness program designed to support gut healing, boost metabolism, and promote noticeable weight loss. More than just a trendy fad, this nutrient-dense approach leverages the power of bone broth—a centuries-old staple in traditional medicine—to help reset digestion, reduce inflammation, and nourish the body at a cellular level. In this comprehensive guide, you’ll learn everything you need to know about the 2 week bone broth diet, from its origins and benefits to practical tips, recipes, and long-term impacts.
The Origins of the Bone Broth Diet
Bone broth has long been a cornerstone of ancestral diets, revered across cultures for its healing properties. From ancient Chinese medicine to Eastern European peasant soups, simmering bones and connective tissues was a way to extract collagen, minerals, and amino acids to fortify the body and aid recovery.
The modern bone broth diet was popularized by Dr. Kellyann Petrucci, a naturopathic physician and wellness expert. In her book The Bone Broth Diet, she outlines a 21-day program combining intermittent fasting, whole food eating, and daily bone broth consumption to support weight loss and gut health. While her original plan spans three weeks, many people adapt it into a 2 week version for a quicker detox or metabolic reset.
This shortened version maintains the core principles: reduce inflammation, heal the gut, and encourage fat-burning—without extreme deprivation.
How the 2 Week Bone Broth Diet Works
The 2 week bone broth diet blends elements of paleo eating, intermittent fasting, and nutrient-dense food choices. It’s not just about drinking bone broth, but restructuring your entire eating pattern to emphasize gut-friendly, anti-inflammatory meals.
Diet Framework and Daily Structure
The diet typically follows this pattern:
- Intermittent Fasting: You fast for 24 hours weekly, consuming only bone broth on designated days.
- Whole Food Eating: On non-fasting days, meals consist of lean proteins, leafy greens, healthy fats, and low-carb vegetables.
- Bone Broth Consumption: You drink at least one cup of bone broth daily, with heavier intake on fasting days (up to 6 cups).
This cyclical approach allows your digestive system a break while flooding your body with essential nutrients.
Key Rules of the 2 Week Plan
- No processed foods, refined sugar, grains, or legumes
- Avoid dairy (except for limited goat or sheep dairy if tolerated)
- Emphasize organic, grass-fed meats and wild-caught fish
- Drink 1–2 liters of water daily
- Prioritize sleep and stress management
The bone broth serves as both a satisfying hunger suppressant and a delivery system for gut-healing compounds like collagen and gelatin.
Health Benefits of the 2 Week Bone Broth Diet
While many approach this diet for weight loss, its benefits go far beyond the scale. Scientific and anecdotal evidence point to a range of wellness improvements.
1. Supports Gut Health and Leaky Gut Repair
One of the most compelling reasons to try the bone broth diet is its impact on gut integrity. Leaky gut syndrome—where the intestinal lining becomes permeable, allowing toxins into the bloodstream—is linked to autoimmune diseases, food sensitivities, and chronic inflammation.
Bone broth is rich in collagen, gelatin, and amino acids like glutamine, all of which help rebuild the gut lining. Glutamine, in particular, is a preferred fuel source for intestinal cells, promoting repair and reducing inflammation.
2. Promotes Weight Loss
The 2 week bone broth diet often results in rapid initial weight loss. This stems from several factors:
- Reduced calorie intake during broth-only fasting days
- Lower insulin levels due to carb restriction
- Increased satiety from high-protein, high-fat meals
- Reduced bloating and water retention from decreased inflammation
In clinical settings, low-carb, high-protein diets are shown to enhance fat oxidation and suppress appetite—key mechanisms behind this diet’s effectiveness.
3. Boosts Immune Function
Bone broth contains minerals like zinc, magnesium, and selenium, all essential for immune health. Additionally, the amino acid arginine supports immune cell function, while glycine possesses anti-inflammatory effects. These synergistic components may help reduce the frequency of colds and chronic low-grade infections.
4. Enhances Joint and Skin Health
Collagen is the most abundant protein in the body, crucial for skin elasticity, hair strength, and joint cushioning. As we age, collagen production declines. Regular bone broth consumption provides the building blocks—like proline and glycine—to stimulate natural collagen synthesis.
Studies show that supplemental collagen improves skin hydration, reduces wrinkles, and alleviates joint pain in people with osteoarthritis. Participants in the bone broth diet often report softer skin and greater joint mobility within days.
5. Reduces Inflammation
Chronic inflammation underlies many modern diseases, including heart disease, diabetes, and arthritis. The 2 week bone broth diet eliminates pro-inflammatory foods (sugar, grains, dairy) while emphasizing antioxidant-rich vegetables and omega-3 fatty acids from fish and seeds.
Glycine, found abundantly in bone broth, acts as an inhibitory neurotransmitter and has been shown in animal studies to suppress inflammatory markers like TNF-alpha and IL-6.
What’s Allowed and What’s Not on the Diet
To maximize results, clarity on food choices is essential. The diet aligns closely with the paleo protocol, eliminating foods linked to gut irritation and insulin spikes.
Foods to Embrace
| Food Group | Examples |
|---|---|
| Proteins | Grass-fed beef, free-range chicken, wild-caught salmon, eggs |
| Vegetables | Spinach, kale, broccoli, zucchini, cauliflower, asparagus |
| Healthy Fats | Avocado, olive oil, coconut oil, grass-fed butter (ghee) |
| Low-Sugar Fruits | Berries (in moderation), green apples |
| Beverages | Bone broth, herbal teas, water, diluted lemon water |
Foods to Avoid
| Food Group | Reason to Avoid |
|---|---|
| Grains | Contain gluten and lectins that irritate the gut lining |
| Dairy (except ghee) | Cow’s milk proteins (casein) and lactose can promote inflammation |
| Sugar and artificial sweeteners | Feed harmful gut bacteria and spike insulin |
| Legumes | High in phytates and lectins, which may hinder digestion |
| Processed oils | Soybean, corn, and canola oils promote oxidative stress |
Strict adherence during the 2 weeks increases the chances of noticeable results.
Sample 2 Week Bone Broth Diet Plan
To help you visualize how the diet unfolds, here’s a sample 7-day cycle (to be repeated for two weeks with variations).
Day 1–6: Regular Eating Days
Breakfast: Scrambled eggs with spinach and avocado
Lunch: Grilled chicken salad with olive oil dressing
Dinner: Baked salmon with roasted broccoli and sweet potato
Beverage: 1–2 cups bone broth throughout the day
Day 7: Broth Fasting Day
On this day, you consume 5–6 cups of bone broth, spaced every 2–3 hours. Optional additions:
- Herbal tea (e.g., chamomile or ginger)
- Lemon water
- Small cup of bone broth with added turmeric or garlic for anti-inflammatory effect
No solid food is consumed, although some versions allow a light salad (1 cup greens with olive oil) if needed.
Bone Broth Preparation Tips
To get the most from your broth, consider these best practices:
- Use organic, pasture-raised bones (beef, chicken, or fish)
- Include joints and marrow bones for maximum gelatin and minerals
- Simmer for 12–24 hours (chicken), 24–48 hours (beef)
- Add apple cider vinegar (1–2 tbsp) to draw out minerals
- Season lightly with herbs (thyme, rosemary) and a pinch of sea salt
A typical recipe:
- Place 2 lbs of bones in a large stockpot or slow cooker.
- Add 1 tablespoon apple cider vinegar and enough cold water to cover.
- Let it sit for 30 minutes (helps extract minerals).
- Add chopped vegetables (carrot, celery, onion) and herbs.
- Simmer on low heat for 24 hours, skimming foam as needed.
- Strain and store in glass jars (up to 5 days in the fridge or 6 months frozen).
What to Expect During the 2 Weeks
Embarking on a new eating plan often comes with physical and emotional adjustments. Knowing what to expect can improve compliance and reduce discouragement.
Days 1–3: Detox and Adjustment
Many people experience mild detox symptoms:
- Headaches
- Fatigue
- Irritability
- Sugar cravings
These are signs that your body is shifting from burning glucose to burning fat (a metabolic state called ketosis). Staying hydrated and drinking warm broth can ease the transition.
Days 4–7: Increased Energy and Reduced Cravings
By the end of the first week, most adjustments settle. Digestion typically improves, and many report:
- Clearer skin
- Reduced bloating
- Better sleep
- More mental clarity
The gut-healing effects often become noticeable around this phase.
Week 2: Momentum and Results
As the body adapts, results compound. Weight loss may slow but continue steadily. Subjective benefits like joint comfort and mood stability often improve. It’s common to lose between 5 to 10 pounds in two weeks, though individual results vary.
Pro tip: Take photos and measurements at the start and end to track visible changes, especially if the scale doesn’t reflect improvements in body composition.
Who Should Consider the 2 Week Bone Broth Diet?
This diet isn’t for everyone, but it may be ideal for individuals in certain situations.
Great Candidates Include:
- People with digestive issues (IBS, bloating, food sensitivities)
- Those looking to kickstart weight loss
- Individuals recovering from illness or surgery
- Anyone seeking a short-term detox from processed foods
- People transitioning to a paleo or low-carb lifestyle
Caution Is Advised For:
- Pregnant or breastfeeding women

- Individuals with kidney disease (high protein diets may not be suitable)
- Those on certain medications (e.g., insulin or blood pressure drugs)
Always consult your healthcare provider before starting any new eating plan, especially one involving fasting.
Maximizing Success on the Diet
Preparation and mindset are key to completing the 2 week bone broth diet successfully.
Plan Ahead
- Make a shopping list and stock your kitchen before Day 1
- Prepare large batches of bone broth and freeze in portions
- Plan meals weekly to avoid decision fatigue
Stay Encouraged
Track non-scale victories: better digestion, improved skin, reduced joint stiffness. Journal your experience to reflect on subtle shifts.
Mindful Movement
While the diet doesn’t require exercise, gentle activity supports results:
- Daily walks (20–30 minutes)
- Stretching or yoga
- Low-intensity strength training
Avoid intense workouts during fasting days to prevent fatigue.
After the 2 Weeks: What Comes Next?
The end of the 2 week plan is not a return to old habits. It’s an opportunity to build sustainable wellness.
Maintain Bone Broth as a Lifestyle Habit
Many people choose to drink bone broth 3–4 times a week even after the diet ends. It’s an easy way to continue supporting gut and joint health.
Gradual Reintroduction of Foods
If you’ve eliminated foods like dairy or grains, you might consider reintroducing them one at a time to identify sensitivities. This elimination-reintroduction strategy is powerful for uncovering root causes of bloating or fatigue.
Transition to a Balanced, Whole-Food Diet
You can evolve into a long-term eating style like:
- Paleo
- Primal
- Mediterranean
- Low-FODMAP (for sensitive guts)
The goal is to maintain the anti-inflammatory principles learned during the 2 weeks.
Common Challenges and How to Overcome Them
Even with motivation, hurdles may arise.
Challenge: Boredom with Food
Solution: Get creative with seasonings and recipes. Try bone broth-based soups, stews, or even use broth to cook rice (if reintroducing carbs). Add fresh herbs, lemon juice, or hot sauce for flavor.
Challenge: Social Pressure
Dining out or attending events can be tricky. Choose gatherings wisely. When eating out, opt for grilled meat and extra vegetables, and skip the bread basket.
Challenge: Fasting Day Struggles
Some find the broth-only day difficult. Try spacing your cups every 2 hours and sip slowly. Focus on resting, meditating, or journaling instead of work or errands.
The Science Behind Bone Broth: What the Research Says
While traditional use supports bone broth’s benefits, modern science is catching up.
- A study in Current Developments in Nutrition found collagen supplementation improved joint pain in physically active adults.
- Research in Gut journal links intestinal permeability to autoimmune conditions, underscoring the importance of gut healing.
- Glycine has been shown in multiple animal studies to reduce oxidative stress and support liver detoxification.
- Glutamine is widely used in clinical nutrition to support gut barrier function in critically ill patients.
While more human trials are needed, the existing evidence supports the inclusion of collagen-rich foods like bone broth in a health-supportive diet.
Is the 2 Week Bone Broth Diet Sustainable?
The 2 week duration makes this plan highly accessible. Unlike extreme cleanses, it doesn’t require expensive supplements or strict isolation. When done right, it’s nourishing, not depleting.
Long-term sustainability comes from adopting pieces of the protocol—not the entire restrictive plan. Incorporating bone broth, reducing processed foods, and practicing mindful eating can all become lasting habits.

What is the 2 Week Bone Broth Diet?
The 2 Week Bone Broth Diet is a short-term eating plan designed to reset your digestive system, reduce inflammation, and promote overall health by incorporating bone broth as a central component of your daily meals. Developed by Dr. Kellyann Petrucci, this diet blends elements of the paleo diet with intermittent fasting and emphasizes whole, unprocessed foods. The foundational idea is that bone broth, rich in collagen, amino acids like glycine and proline, and essential minerals, supports gut healing and boosts immunity while promoting fat loss.
Over the course of 14 days, participants consume bone broth multiple times a day—typically as part of meals or as a substitute for snacks—while avoiding grains, dairy, legumes, and added sugars. The diet encourages the intake of lean proteins, vegetables, healthy fats, and limited fruits to keep inflammation low and energy levels stable. By focusing on nutrient-dense foods and allowing the gut to rest and repair, the 2 Week Bone Broth Diet aims to kickstart healthier eating habits and improve metabolic markers.
How does bone broth support health during the diet?
Bone broth is the cornerstone of this diet due to its rich nutritional profile, which includes collagen, gelatin, and key minerals such as calcium, magnesium, and phosphorus. These components are released when animal bones and connective tissues are simmered for extended periods, often 12 to 24 hours. Collagen, in particular, plays a vital role in maintaining the integrity of the gut lining, potentially reducing intestinal permeability—commonly known as “leaky gut”—and decreasing systemic inflammation.
In addition to gut health, the amino acids in bone broth—such as glycine and proline—contribute to joint health, skin elasticity, and improved sleep quality. Glycine also supports liver detoxification and helps regulate blood sugar. Drinking bone broth can promote satiety, making it easier to adhere to the reduced-calorie, anti-inflammatory eating pattern of the diet. This combination of digestive repair, reduced inflammation, and sustained energy makes bone broth a powerful ally in the 2 Week Bone Broth Diet.
What foods are allowed on the 2 Week Bone Broth Diet?
The 2 Week Bone Broth Diet emphasizes whole, nutrient-dense foods that support healing and weight loss. Participants are encouraged to eat lean proteins like chicken, turkey, fish, and grass-fed beef, along with a wide variety of non-starchy vegetables such as leafy greens, broccoli, zucchini, and cauliflower. Healthy fats from sources like avocado, olive oil, coconut oil, and nuts are also permitted in moderation. Limited quantities of low-glycemic fruits—such as berries—are allowed, particularly in the early phase of the diet.
Grains, dairy, legumes, processed foods, and added sugars are strictly avoided to reduce inflammation and support gut healing. These foods can irritate the digestive tract or spike insulin levels, counteracting the diet’s benefits. Each day typically includes three main meals, often accompanied by 2–4 cups of bone broth, which can be sipped throughout the day or used as a base for soups and stews. This structured approach ensures consistent nutrient intake while allowing the body to focus on repair and rejuvenation.
Can the 2 Week Bone Broth Diet help with weight loss?
Yes, many people experience weight loss during the 2 Week Bone Broth Diet, primarily due to the combination of reduced calorie intake, elimination of processed foods, and the satiating effects of bone broth. Because bone broth is rich in protein and collagen, it helps keep you full between meals, reducing overall food consumption without triggering hunger pangs. Additionally, eliminating inflammatory foods like sugar and grains can lead to a drop in water retention and bloating, contributing to noticeable changes on the scale.
Beyond short-term weight loss, the diet aims to reset metabolism and reduce cravings by stabilizing blood sugar levels and improving gut health. The intermittent fasting component—often achieved by skipping snacks and consuming bone broth instead—may also support fat burning by extending the time your body spends in a fat-burning state. While individual results vary, many participants report losing between 5 to 15 pounds over the two-week period, along with improved energy and digestion.
Is the 2 Week Bone Broth Diet safe for everyone?
For most healthy individuals, the 2 Week Bone Broth Diet is considered safe when followed as directed. It focuses on whole foods and eliminates common allergens and inflammatory ingredients, which can benefit people with digestive issues or autoimmune conditions. However, because it involves caloric restriction and elimination of food groups, it may not be appropriate for everyone. Pregnant or breastfeeding women, individuals with eating disorders, or those with chronic medical conditions should consult a healthcare provider before beginning.
People with kidney disease or those on certain medications may need to be cautious due to the high mineral content in bone broth or changes in protein intake. Additionally, relying heavily on bone broth could lead to imbalances if not combined with a variety of nutritious foods. While the short duration of the diet reduces long-term risks, it’s important to approach it as a temporary reset rather than a permanent solution. Professional guidance is recommended to ensure safety and nutritional adequacy.
How do you make bone broth for the diet?
To make bone broth suitable for the 2 Week Bone Broth Diet, start by sourcing high-quality bones—preferably from pasture-raised or grass-fed animals—such as beef, chicken, or fish. Place the bones in a large stockpot or slow cooker, cover them with filtered water, and add a splash of apple cider vinegar to help draw out minerals. Include vegetables like carrots, onions, and celery, along with herbs such as thyme, rosemary, or bay leaves for added flavor and nutrients.
Simmer the mixture on low heat for 12 to 24 hours, allowing the collagen, gelatin, and minerals to fully extract into the broth. Avoid boiling vigorously, as this can break down nutrients. After cooking, strain the liquid through a fine mesh sieve, then cool and store it in the refrigerator for up to 5 days or freeze for longer storage. Homemade bone broth is ideal for the diet, but store-bought versions can be used if they are low in sodium and free of additives and preservatives.
What are the potential side effects of the 2 Week Bone Broth Diet?
Some individuals may experience mild side effects when starting the 2 Week Bone Broth Diet, particularly during the first few days. These can include fatigue, headaches, or irritability—often due to the elimination of sugar, caffeine, and processed carbohydrates, which the body may be accustomed to. This “detox” phase is typically temporary and may subside as the body adjusts to burning fat for fuel and stabilizing blood sugar levels.
Drinking large amounts of bone broth could potentially lead to an excess intake of certain minerals like calcium or lead—especially if bones are not sourced responsibly. Some people may also experience digestive discomfort, such as bloating or constipation, if the increase in collagen and protein intake is sudden. Staying well-hydrated and including fiber-rich vegetables can help mitigate these effects. Listening to your body and adjusting portion sizes or ingredients as needed can enhance the experience and reduce adverse reactions.
