Kim Kardashian’s physique has been a continuous topic of global discussion, and as of late December 2025, the reality star and business mogul continues to showcase a notably strong and sculpted body.

Understanding Kim’s current nutritional balance and fitness regimen requires looking beyond the headlines to the specific, high-intensity training and mindful eating practices she employs today.

Secret #1: The Current Plant-Based and Whole Foods Focus

While Kim has experimented with numerous diets, her current, long-term strategy, which she has followed since around 2019, is a mostly plant-based diet. This shift is not strictly vegan, as she has been known to occasionally consume meat, but the core of her meals revolves around whole, nutrient-dense foods.

Her focus is on consuming a harmonious blend of taste and nutrition, ensuring her body is fueled for her intense workout schedule.

• Daily Staples: Oatmeal, big salads, vegan sausage, and vegan tacos are among her go-to meals.
• Key Avoidances: She is known to strictly avoid sugar and processed foods to maintain her physique and support her overall well-being.
• Health Benefit: Kim has publicly stated that her mostly vegan diet helps her manage symptoms of psoriasis.

Secret #2: The Intense Weightlifting and Strength Training Regimen

Kim’s current sculpted look is less about cardio and more about serious resistance training. She works out for a grueling hour and a half every day, typically five to six days a week.

Her routine is heavily focused on strength training and weightlifting, targeting different muscle groups on separate days, including upper body, lower body, and abs. This focus on building muscle mass is a key factor in boosting her metabolism and achieving a toned physique, a significant departure from diets that solely rely on calorie restriction.

Her current personal trainer, Senada Greca, is a renowned fitness expert who emphasizes the importance of weight training for women, helping Kim to achieve her current level of physical fitness.

Secret #3: The Controversial 16-Pound Met Gala Crash Diet

One of the most talked-about and controversial aspects of her diet history is the extreme regimen she followed to fit into Marilyn Monroe's iconic dress for the Met Gala. This was a short-term, drastic measure, not a sustainable lifestyle.

To lose 16 pounds in just three weeks, Kim employed a severe strategy:

• Complete Restriction: She completely cut out all sugar and all carbohydrates.
• Diet Focus: She ate only the "cleanest veggies and protein."
• Extreme Exercise: She would run on the treadmill and wear a sauna suit twice a day to maximize water weight loss.

Experts and nutritionists widely criticized this approach as an unsafe and unsustainable crash diet, highlighting the difference between a temporary stunt and a healthy, long-term mindful eating plan.

Secret #4: The Return to Complex Carbohydrates

Despite the high-profile Atkins Diet and Met Gala carb-cutting, a former chef revealed a surprising truth: Kim actually loves carbs. Her current, more balanced approach incorporates complex carbohydrates, which are essential for fueling her intense strength training sessions.

The key is distinguishing between processed, simple carbs (which she avoids) and nutrient-rich, complex carbohydrates like those found in whole grains, fruits, and vegetables, which provide sustained energy and support muscle recovery.

Secret #5: Leveraging the Carb-Conscious Atkins Diet for Post-Pregnancy Weight Loss

Before her plant-based shift, the Atkins diet was her go-to for significant weight loss. After the birth of her son, Saint West, Kim used the carb-conscious, fat-burning Atkins plan to successfully shed 60 pounds. This structured, high-protein, low-carbohydrate diet allowed her to feel satisfied while rapidly losing weight.

The Atkins plan is a classic example of a diet that focuses on lean proteins and healthy fats while severely limiting carbohydrate intake, making it effective for quick results but requiring careful management for long-term health.

Secret #6: The Role of Strategic Supplementation

In addition to her diet, Kim has been linked to various supplements to aid her wellness and cellular health. One of the more recent supplements mentioned in her routine is NMN (Nicotinamide Mononucleotide).

NMN is a precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a coenzyme that plays a crucial role in metabolism and cellular energy production. By restoring these levels, NMN is believed to promote better metabolism and overall health. She has also been associated with other supplements like apple cider vinegar and fat-burning pills in the past, though these are often part of broader celebrity wellness trends.

Secret #7: The Discipline of Consistency and Professional Guidance

Ultimately, the most enduring secret to Kim Kardashian's physique is not a single diet but an unwavering commitment to consistency, guided by professionals. Her approach in 2024 and beyond is a disciplined regimen that relies on a team of experts.

• Professional Team: She works closely with personal trainers (like Senada Greca) and professional nutritionists to create a personalized plan.
• Discipline: Her daily 1.5-hour workouts, even on busy days, demonstrate a level of discipline that is non-negotiable for her.
• Adaptability: She has successfully transitioned from extreme, short-term diets to a more sustainable, plant-based lifestyle that supports her intense weightlifting goals and manages her health conditions.

Kim Kardashian’s diet and fitness journey is a testament to the fact that maintaining a celebrity-level physique requires extreme dedication. While her past methods, such as the Met Gala crash diet, were controversial and unsustainable, her current focus on a mostly plant-based diet, rigorous strength training, and professional nutritional balance offers a more realistic, albeit still highly disciplined, blueprint for a major body transformation.
