The Framework of the Bone Broth Diet
Developed by Dr. Kellyann Petrucci, the bone broth diet is a 21-day plan that incorporates several popular dietary principles, including elements of paleo, low-carb, and intermittent fasting. The regimen divides the week into two types of days: five "eating days" and two "fasting days." Throughout the entire diet, the cornerstone is the regular consumption of bone broth, a nutrient-dense liquid made by simmering animal bones and connective tissue.
On the five eating days, participants follow a paleo-style meal plan focusing on whole, unprocessed foods. This approach eliminates food groups like grains, dairy, legumes, and refined sugars. The two mini-fasting days, which should be non-consecutive, involve consuming only bone broth, along with water and herbal tea. The diet's proponents suggest this combination can lead to weight loss, improved gut health, and reduced inflammation. However, it is important to note that some benefits are anecdotal, and consulting a healthcare professional is always recommended before starting a new diet plan.
Allowed Foods on the Bone Broth Diet
The majority of your food intake on this diet will occur on the five regular eating days. The focus is on nutrient-dense, whole foods that align with a low-carb, anti-inflammatory eating pattern.
Proteins
Protein is a critical component for satiety and muscle maintenance. The diet emphasizes high-quality, unprocessed protein sources.
- Meat and Poultry: Organic, grass-fed beef, pastured chicken, and organic turkey are encouraged. Ground turkey or chicken sausage can be used for convenience.
- Fish and Seafood: Wild-caught fish, such as salmon, tuna, and tilapia, are excellent choices. Other seafood like shrimp is also permitted.
- Eggs: Pasture-raised eggs are a staple and can be cooked with healthy fats like ghee or avocado oil.
Vegetables
Most vegetables are allowed, with a strong emphasis on non-starchy options. These provide essential vitamins, minerals, and fiber, which is especially important given the diet’s low-fiber nature on fasting days.
- Non-Starchy Vegetables: Asparagus, broccoli, leafy greens (spinach, arugula, kale), bell peppers, cucumbers, zucchini, and mushrooms should make up a large portion of your plate.
- Limited Starchy Vegetables: Smaller amounts of starchy vegetables like sweet potatoes and carrots are permitted.
Healthy Fats
Healthy fats are crucial for providing energy and promoting fullness, especially with the reduced carbohydrate intake.
- Avocados: A rich source of healthy monounsaturated fats.
- Nuts and Seeds: A handful of nuts like almonds or seeds such as chia seeds can serve as a snack.
- Oils: Olive oil, avocado oil, and coconut oil are recommended for cooking and dressings. Ghee, a type of clarified butter, is also an option.
Fruits
Fruits are limited to low-glycemic varieties and should be consumed in moderation, typically one portion per day on eating days.
- Berries: Blueberries, raspberries, and strawberries are good options.
- Apples and Pears: Low-glycemic fruits like apples and pears are acceptable.
The Role of Bone Broth and Fasting Days
Bone broth is the centerpiece of the diet, consumed daily on eating days and as the sole source of calories on fasting days. On fasting days, you will consume 5-6 cups of bone broth spread throughout the day. Homemade bone broth is highly encouraged, but high-quality, store-bought versions are also acceptable.
Foods to Avoid
The bone broth diet is restrictive and eliminates several food groups to promote anti-inflammatory effects.
- Grains and Legumes: This includes wheat, corn, rice, oats, bread, pasta, beans, chickpeas, and peanuts.
- Dairy Products: Milk, cheese, yogurt, and ice cream are excluded, with ghee being the only exception.
- Sugar and Artificial Sweeteners: All forms of refined sugar, as well as honey, maple syrup, and artificial sweeteners, are prohibited.
- Processed Foods: This includes most packaged and convenience foods, like chips, cereals, and baked goods.
- Alcohol: All alcoholic beverages should be avoided.

Final Thoughts on the Bone Broth Diet
The bone broth diet offers a structured, short-term approach to eating that emphasizes whole, unprocessed foods and includes periods of caloric restriction through mini-fasting days. The food choices are designed to reduce inflammation and promote satiety, with lean proteins, healthy fats, and non-starchy vegetables forming the core of the meal plan. However, the diet's restrictive nature may lead to nutritional deficiencies if followed long-term or without proper planning. It's also important to acknowledge that some of the health benefits are not yet supported by extensive scientific research. For those considering the diet, focusing on the principle of eating high-quality, nutrient-dense foods can be a takeaway, even if they choose not to follow the restrictive fasting protocol. As with any significant dietary change, discussing the bone broth diet with a healthcare provider or a registered dietitian is advisable.
Conclusion
The bone broth diet requires careful planning, with specific guidelines on what foods you can eat on the bone broth diet. By focusing on whole foods like lean meats, fish, non-starchy vegetables, and healthy fats, along with regular bone broth consumption and intermittent fasting, the diet aims to support weight loss and overall wellness over a 21-day period. Adhering to the allowed foods while avoiding grains, dairy, legumes, and sugar is fundamental to the diet's structure, but long-term sustainability requires a more balanced approach. It is always best to listen to your body and seek expert medical advice for a nutrition plan that is right for you.
