The main idea is that humans thrive on an animal-based diet while avoiding all plant foods. Proponents argue this diet can lead to weight loss, improved mental clarity, and reduced inflammation. From a gut and general health perspective, because of the lack of dietary fibre the carnivore diet is criticised for being unhealthy. Fibre is considered to be important for human health, due to the benefits of fibre on the gut microbial diversity and the products of microbial fermentation. Whilst change in dietary fibre intake can acutely alter microbiota composition, microbial diversity may be retained on an animal-based diet [45].

The keto diet, on the other hand, keeps carb intake low and fat intake high, which, theoretically, puts the body in a state of ketosis where it burns fat for energy. In a Harvard Medical School article, Dr. Howard E. LeWine says that in the keto diet, about 10% of calories come from carbs, and that the food that makes up this percentage can vary. The carnivore diet allows only meat, fish, seafood, eggs, and some dairy. It might be one of the few, or only, well-known diets that excludes produce. Since then, the diet has gained a lot of traction online—how could someone biting into a stick of butter not grab your attention?

But with so many varied claims and stories from both influencers and doctors, it’s difficult to sort fact from myth. Could someone really be healthy consuming only steak, eggs, butter, and no veggies? Instead of eliminating food groups, focus on easy swaps you can make to ensure you get the protein, complex carbs, and healthy fats you need to feel your best.

Imagine if you could lose weight and supercharge your health while eating all the ribeye steaks you want — but only if you skip the potato and side salad. That’s the promise of the carnivore diet, a weight-loss approach that allows you to chow down on infinite quantities of meat and very little else. Additionally, fiber is incredibly important for the proper balance www.reviews.io/company-reviews/store/unimeal-com of bacteria in your gut. In fact, suboptimal gut health can lead to a number of issues and may even be linked to colon cancer. While meat is nutritious and provides many micronutrients, it should not be the only part of your diet.
Health Benefits
This dietary pattern is low in carb-rich foods and high in protein, the most filling macronutrient. However, due to there being multiple mechanisms through which calcium, magnesium, and potassium homeostasis is regulated (i.e., intestinal absorption, renal re-absorption/excretion, and bone resorption), acute deficiency diseases are uncommon [27]. The NRVs are a set of recommendations for nutritional intake based on currently available scientific knowledge. Supporters of the high-protein (and high-fat) diet argue that it can help you lose weight and protect against chronic diseases by eliminating carbs and plant-based foods. Like the carnivore diet, the low-carb diet may offer health benefits, such as weight loss and better blood sugar control.
What can (and can’t) you eat on the carnivore diet?
- “Science doesn’t support cutting out carbohydrates for depression,” Gannon says.
- The carnivore diet might have its place in a small percentage of the population that has severe, unresolved inflammatory conditions.
- Advocates encourage fattier cuts of meat to ensure daily energy needs are met.
- Another area of concern is the lack of dietary fiber in the carnivore diet.
- In the short term, it often delivers, especially for those who previously consumed large amounts of ultra-processed foods.
- This weight loss method is also referred to as a ketogenic or “keto” type diet.
“Others don’t do well on it—they might feel sluggish, constipated, or just miss variety in their diet,” he adds. “Our bodies, genetics, and gut health all respond differently to big changes like this.” The analysis shows that all four versions unimeal reviews on reviews.io of the carnivore diet achieved most NRV thresholds.
Nutrition
The carnivore diet takes “low-carb” to its extreme, eliminating all plant foods in favor of meat, eggs, and dairy. The carnivore and paleo diets are also similar in that both are low-carbohydrate diets and may promote weight loss and better blood sugar control in the short term. Some research shows that a low-carb or zero-carb diet may help with blood sugar maintenance, especially in those with type 2 diabetes. Compared to other macronutrients, carbohydrates have the greatest impact on blood sugar. This is why low-carbohydrate diets (like the carnivore diet) are thought to reduce overall blood sugar.
May Improve Blood Sugar Regulation
Meal plans which included iodised salt resulted in the RDI for iodine being exceeded, whereas without iodised salt, iodine intake only exceeded the RDI for the male meal plan (meal plan 3). But digestion is only one part of the story—inside the body, the absence of plants triggers a cascade of nutrient losses. Without fruits, vegetables, and grains, the body loses access to crucial nutrients—vitamin C, antioxidants, and plant-based compounds known as phytonutrients—that help fight inflammation and support long-term health.
Is fiber the secret to a healthier gut? Here’s how to get more fiber in your diet
“Fiber provides numerous benefits to overall health, including lowering cholesterol, stabilizing blood sugar and promoting weight loss,” Lisa said. The popularity of the carnivore diet comes from the controversial belief that the diets of human ancestral populations consisted mostly of meat and fish, and the high-carb diets are the cause of the chronic conditions we see today. Given the diet’s high consumption of meat and saturated fat, both experts also note the potential negative impact on heart health. Another concern with the carnivore diet is its environmental impact, given the dietary pattern’s high consumption of red meat and other animal products. By completely excluding plants, the carnivore diet provides zero dietary fibre.
How to follow it, what is on the approved food list, what are the potential health benefits, and what considerations should be kept in mind. There are many risk factors for heart disease beyond cholesterol, Norwitz noted. These include visceral fat, insulin resistance, inflammation triglycerides and HDL, all of which could actually be improved on very low-carbohydrate diets. Collectively we must accept that global food production needs a major shake-up if population nutritional needs are going to be met whilst also attempting to hold back the overshadowing climate change disaster. Reducing meat consumption is an essential component of the move towards sustainable, healthy food systems. The carnivore diet flies in the face of this global mission for planetary health, for the sake of perceived personal gains.
Gut health and diversity
These contexts, including offal and/or nutritional supplements may be necessary parts of the diet. Particular micronutrients of concern identified in our analysis include thiamin, folate, Vitamin C, calcium, magnesium, and potassium. Micronutrient supplementation is advisable, initially, during the first phases of the diet for those with prior health conditions [13], such as inflammatory bowel disease [34], that may mean poor nutrient status to start. Long-term use of the diet may also require additional supplementation, particularly when a limited variety of animal-based products is consumed.
