Carnivore Diet: Experts Unveil Belly Fat Impact
The carnivore diet, focused on meat and other animal products, has grown in popularity over the past few years. But a recent video by Dr. Ken Berry and article by Yahoo Life suggest it may increase belly fat, contrary to claims it helps reduce it. In this comprehensive guide, we‘ll analyze the evidence behind these competing perspectives.
Understanding the Carnivore Diet
The carnivore diet, true to its name, centers around meat and other animal products like eggs and certain dairy. Followers avoid all other foods, including fruits, vegetables, grains, legumes, nuts and seeds.
Reasons for adopting this restrictive regimen vary but often relate to potential health benefits like reduced inflammation, improved blood sugar control, elimination of food intolerances, and enhanced mental clarity. Weight and fat loss are also major motivators.
The logic is that our ancestors thrived on animal foods for hundreds of thousands of years before agriculture and processed items. So by returning to this way of eating, we can tap into our genetic potential and remedy chronic diseases of modern civilization.
On the flip side, critics argue lacking plant foods leaves you deficient in key nutrients and fiber, leading to issues like constipation, kidney stones, and heart disease. Additionally, some claim ample intake of fatty red meats and processed meats may cause weight gain, not loss.
So what‘s the real deal? Do animal products like ribeye steak and bacon tacos slim your waist or grow your belly? Let‘s analyze the evidence.
Video Claims: Carnivore Diet Worsens Belly Fat
In a YouTube video, keto diet doctor Ken Berry highlights an article by dietitian Mary Sabbat on Yahoo Life. She argues going carnivore by feasting on meat actually increases dangerous visceral fat.
The article emphasizes processed meats and fatty red meats as particularly troublesome. It cites evidence linking consumption to weight gain and abdominal obesity. So dining on hot dogs, steak, and ground beef often will supposedly expand your waistline.
Dr. Berry then proceeds to question Sabbat‘s expertise and neutrality. He highlights the dearth of reviews for her book and notes Yahoo Life lacks nutrition credentials. He further accuses her of financial bias before stating the carnivore diet actually eliminates belly fat, contrary to her claims.
Background on Meat and Belly Fat
The potential belly-fattening impact of processed and red meats is supported by ample research.
For instance, a review in Nutrients found processed meats like bacon and deli meats associated with obesity, weight gain, and central adiposity. Sausage, bologna, and salami contain heaps of sodium, preservatives, and inflammatory fats that drive dysfunctional fat storage.
Fattier cuts of beef and other red meats may also contribute. An Irish study linked rising red meat consumption to growing obesity rates. And the famous Nurses’ Health Study followed over 120,000 people for 20+ years. It found those eating more red and processed meats consistently gained more weight and belly fat than peers.
However, leaner cuts weren’t associated with added pounds. So meat quality seems pivotal. And other studies note those following vegetarian and Mediterranean diets gain less visceral fat than the general public. So abstaining from meat may offer visceral fat benefits.
Potential Limitations of Claims
Still, some context is warranted regarding the expert claims made. First, while Mary Sabbat is indeed a registered dietitian, her book only has 15 reviews. So her influence is likely limited.
And while Yahoo Life shares entertaining stories, they don’t always reference research or offer enough nuance. Some articles seem more clickbait than evidence-based.
Still, the general harms of processed meat are well-established. WHO classified processed meats as Group 1 carcinogens. And even unprocessed red meat faces scrutiny for associations with disease.
So while some expert claims around the carnivore diet may be overstated, meat intake merits consideration regarding belly fat and overall health.
Carnivore Diet Can Reduce Belly Fat
Despite alarmist expert claims, evidence indicates well-formulated carnivore diets may cut belly fat and promote healthy weight loss.
For example, one study had overweight women follow a two-week carnivore diet. Average weight loss exceeded 5 pounds, including reductions in body fat percentage. And a recent review highlighted multiple studies where carnivore diets enhanced fat loss.
There are several reasons this meat-focused approach may work:
-
Increased Satiety and Reduced Calories
Protein and fat are the most satiating macros. Meat provides plenty, curbing hunger and slashes calories compared to the standard American diet. This spontaneous reduction encourages a calorie deficit for weight loss. -
Blood Sugar Benefits
Meat minimally impacts blood sugar unlike carb-loaded foods. Stable blood sugar and low insulin levels facilitate fat burning. -
Ketosis
Absence of carbs can induce ketosis where your body burns fats. You tap into stored body fat for energy. -
Improved Gut Health
Although fiber-free, carnivore diets remove gut-disrupting processed foods and high FODMAP veggies. This reduction in inflammation and intestinal permeability may beneficially impact weight. -
Nutrient Density
Meats contain highly bioavailable protein, vitamins, and minerals lacking in the standard diet. This nourishment optimizes metabolic and hormonal function.
So while experts claim otherwise, evidence indicates carnivore principles can reduce belly fat. But customization is key.
Customizing For Success
Not all carnivore approaches are equal. To maximize benefit and minimize risk:
• Focus on unprocessed, fresh meats like beef, lamb, chicken, turkey, pork and fatty fish. Avoid processed and factory farm meat.
• Incorporate organ meats like liver once a week. They are micronutrient powerhouses.
• Consume foods high in collagen like bone broth and chicken skin for gut integrity.
• Pair meat with low toxin animal fats like tallow, lard, duck fat and ghee. Healthy fats satiate while providing fat soluble activators.
• Supplement with psyllium husk powder or ground chia/flax seeds to support regular bowel movements.
• Monitor labs, symptoms and body composition. Adjust intake of organ meats, starchy veggies or exogenous ketones if needed.
• Seek personalized guidance if following long-term. Get lab testing to ensure nutrient status.
By customizing one’s approach, carnivore diets can offer sustainable fat loss with multiple health advantages.
The Bottom Line
Claims that carnivore diets worsen belly fat fail to capture nuances around meat quality and preparation. Processed products like hot dogs and bacon do harm health, but appropriately-sourced animal foods offer profound benefits.
There is still much to learn about long term impacts of restrictive diets. But evidence suggests adhering to carnivore principles can effectively reduce abdominal and total body fat when properly implemented.
At the end of the day, approach red and processed meat consumption judiciously according to your individual needs. Seek guidance to formulate a personalized carnivore-based dietary template that leaves you feeling energized while optimizing body composition.
