Hollywood star swapped vegan for a carnivorous diet and claims great health gains

Jenny McCarthy, once on the brink of severe health issues due to her vegan diet, has dramatically changed her regimen to a carnivorous diet, which she now praises for its positive impact on her health.

According to the Daily Mail, Actress Jenny McCarthy describes a critical health turnaround after switching from a vegan to a carnivorous diet due to severe maladies.

Jenny McCarthy, a 52-year-old actress known for her vibrant personality and extensive career in Hollywood, started experiencing significant health issues, which she attributed to her diet. A long-time adherent to veganism, McCarthy recalled the adverse effects the diet had on her health, stating that it almost cost her life.

The vegan diet, which avoids all animal products and emphasizes plants, became a major part of McCarthy's regime. However, complications arose due to her soy allergy—a common protein source for vegans—compelling her to rely heavily on other carbohydrates. This diet significantly worsened her health, leading to extreme lethargy and illness.

Exploration of Alternative Diets Preceded Major Change

In search of relief, McCarthy explored various diets, including low histamine options, which were meant to alleviate her symptoms. Despite these efforts, her health did not improve significantly, prompting her to consult a functional medicine doctor. She explained her reluctance and the bleak expectation she had before making another dietary shift.

"Finally, my functional medicine doctor said to me last year, 'It's time for you to go full carnivore,'" McCarthy recollected. The carnivore diet, often promoted by several health influencers, primarily consists of animal products and excludes most plant-based foods.

Transitioning to a completely different diet was challenging. She was initially hesitant owing to the heavy nature of the diet, which she described as "low vibrational heavy." However, the change eventually led to substantial improvements in her well-being.

Significant Improvement Follows Carnivore Diet Switch

"But I felt I might as well give it a try; it was like my last resort diet. It has been f****** incredible for me and I stress for me," McCarthy expressed. Her testimonial reflects a personal health victory but also underscores the specificity of dietary effects, implying changes may not universally apply to everyone.

However, the carnivore diet is not without criticism. Dr. Shireen Kassam has highlighted that this diet is "nutritionally unbalanced, unsustainable, and potentially harmful in the long run." Risks include increased uric acid production, the potential for kidney stones, and bone health issues due to calcium loss, according to medical experts.

Conversely, the vegan diet has faced its criticisms too. Researchers for The Conversation have stressed that many products labeled as vegan are high in sodium or saturated fat, which undermines their health benefits. "We found some products are so high in salt or saturated fat, we'd struggle to call them 'healthy,'" they reported.

New Dietary Plans Require Careful Consideration

Furthermore, Dr. Eszter Vamos described significant concerns with ultra-processed vegan foods, evident in a large study linking them to adverse health outcomes. "While ultra-processed foods are often marketed as healthy foods, this large study suggests that plant-based ultra-processed foods do not seem to have protective health effects and are linked to poor health outcomes," Vamos commented.

The divergent views on both dietary plans suggest that individual health responses can vary significantly, necessitating personalized medical guidance before undertaking substantial dietary changes.

Jenny McCarthy’s experience underscores the complexities inherent in choosing the right diet for personal health. Her story illuminates how dietary interventions, while beneficial for some, can pose serious health risks without careful consideration and medical oversight.
