The Dubrow Keto Fusion Diet is a novel approach to weight loss and healthy living, developed by Heather and Terry Dubrow, M.D., the authors of the popular "The Dubrow Diet." This new diet book combines the principles of the ketogenic diet and interval eating (also known as time-restricted eating) to offer a simple yet effective plan for sustainable fat burning. The diet is based on a 12:8:4 eating schedule and is designed to help individuals achieve their weight loss goals while enjoying a variety of delicious and healthy foods.
The Genesis of the Dubrow Keto Fusion Diet
What prompted the Dubrows to create a sequel to their successful diet plan? According to Terry Dubrow, M.D., a Yale-trained surgeon, they discovered that some of their followers were already incorporating keto principles into their original Dubrow Diet. Intrigued, they investigated further and realized the potential benefits of combining interval eating with a ketogenic approach. This led to the development of the Dubrow Keto Fusion Diet, which aims to accelerate fat burning and eliminate common challenges associated with traditional dieting.
Understanding the Core Principles
The Dubrow Keto Fusion Diet revolves around three key elements:
1. Interval Eating (Time-Restricted Eating)
The foundation of the Dubrow Diet is interval eating, also known as time-restricted eating. This involves cycling between periods of eating and fasting. The idea behind interval eating is that by extending the periods without food intake, the body exhausts its blood sugar reserves and begins to burn stored fat for energy. The Dubrow Diet recommends a 16:8 schedule, meaning fasting for 16 hours with an 8-hour eating window in the initial phase. Depending on how quickly you want to lose weight, you would then choose a fast of 12, 14, or 16 hours during phase 2 and beyond.
2. Ketogenic Diet
The ketogenic diet is a high-fat, very low-carbohydrate diet that forces the body to enter a metabolic state called ketosis. When carbohydrate intake is drastically reduced, the body begins to break down fat into ketones, which are then used as an alternative fuel source. This process leads to weight loss and other potential health benefits.

3. The 12:8:4 Eating Schedule
The Dubrow Keto Fusion Diet incorporates a specific 12:8:4 eating schedule:
- 12-Hour Fasting Period (Reset): Allow 12 hours to elapse between your last meal of the day and your first meal the next day. During this period, you can consume coffee with cream or bone broth to manage hunger.
- 8-Hour Keto Eating Window (Recharge): For the next eight hours, focus on consuming keto-friendly foods, including protein, low-carb vegetables, and healthy fats.
- 4-Hour Keto-Carb Fusion (Fuel): In the four hours before bed, enjoy a keto-friendly dinner and an optional snack that includes one or two servings of healthy carbohydrates like fruit, potatoes, or brown rice. Dr. Dubrow suggests cooking, cooling, and reheating potatoes or rice to minimize their impact on blood sugar.
How the Fusion Works
The Dubrow Keto Fusion Diet combines the best aspects of both interval eating and the ketogenic diet. Interval eating promotes fat burning by extending periods without food, while the ketogenic diet forces the body to utilize fat as its primary fuel source. By strategically alternating between these two approaches, the diet aims to optimize both sugar and fat burning.
Dr. Dubrow explains that this fusion approach "causes both enzymes that help us burn sugar and enzymes that help us burn fat to become more active." Studies at Israeli universities have shown that similar approaches can lead to significant weight loss compared to traditional eating patterns.
Benefits of the Dubrow Keto Fusion Diet
The Dubrow Keto Fusion Diet offers a range of potential benefits:
- Accelerated Fat Burning: By combining interval eating and keto principles, the diet aims to maximize fat burning efficiency.
- Reduced Hunger and Cravings: The inclusion of healthy fats and strategic carbohydrate intake can help manage hunger and cravings, making the diet more sustainable.
- Improved Metabolic Health: The diet may lead to better blood sugar control, lower blood pressure, and improved cholesterol levels.
- Increased Energy and Improved Mood: By promoting stable blood sugar levels and fat utilization, the diet may enhance energy levels and mood.
- Sustainable Weight Loss: The flexible nature of the diet and the inclusion of occasional cheat days can help individuals maintain their weight loss results over the long term.

The Three Phases of the Dubrow Diet
The Dubrow Diet consists of three phases, each designed to achieve specific goals:
- Phase 1: Kickstart (2-5 days): This phase involves strictly adhering to the 16:8 interval eating schedule to jump-start your body's fat-burning processes.
- Phase 2: Goal Weight Phase: This phase is tailored to your desired weight loss pace.
- Slow Weight Loss: 12:12 interval eating with one "cheat moment" per week, resulting in an estimated 0.5 to 1.5 pounds of weight loss per week.
- Medium Weight Loss: 14:10 interval eating with one cheat meal per week, leading to an estimated 1 to 2.5 pounds of weight loss per week.
- Fast Weight Loss: Maintaining the 16:8 interval with an entire cheat day, resulting in 2 to 4 pounds of weight loss per week.
- Phase 3: Maintenance Phase: This phase focuses on maintaining your weight loss results. For five days of the week, follow a 12:12 interval, and for the remaining two days, implement a 16:8 interval as a reset.
Expert Perspectives
While the Dubrow Keto Fusion Diet has gained popularity, it's essential to consider expert opinions:
- Amy Shapiro, RD, CDN: Shapiro appreciates the diet's emphasis on lean proteins, vegetables, nuts, seeds, and heart-healthy fats. She notes that the diet promotes whole, unprocessed foods. However, she suggests that women may benefit from a shorter fasting window of 12-14 hours.
- Samantha Cassetty, MS, RD: Cassetty acknowledges that intermittent fasting can influence appetite-regulating hormones and create a calorie deficit, leading to weight loss. However, she emphasizes that intermittent fasting is not necessary for everyone and that a balanced diet focused on whole foods is crucial for long-term health.
Potential Downsides to Consider
- Restrictive Nature: The diet's restrictions and specific food lists may make it challenging to adhere to long-term.
- Calorie Restriction: The meal plans can be low in calories, potentially leading to nutrient deficiencies and feelings of hunger or sluggishness.
- Cheat Days: The incorporation of cheat moments or days may promote an unhealthy "on-off" mentality towards eating.
- Not Suitable for Everyone: Individuals with eating disorders, pregnant women, or those under 18 should avoid this diet. People over 65 or with medical conditions should consult their healthcare provider before starting.
- Limited Complex Carbohydrates: The diet's limitations on complex carbohydrates may be restrictive for some individuals.
