The carnivore diet is a restrictive eating plan that eliminates all plant-based foods, focusing solely on animal products. This article delves into what you can expect during the first week of embarking on this dietary journey, drawing upon user-provided information and general knowledge to offer a comprehensive guide.
Introduction to the Carnivore Diet
The carnivore diet involves cutting out carbohydrates and consuming only meat and other animal products like beef, chicken, pork, fish, and eggs. The underlying principle is that by eliminating carbs, the body will switch to burning fat for energy, leading to weight loss. Proponents of this diet also claim it can reduce inflammation, lower blood sugar in individuals with diabetes, and enhance mental well-being.
This diet shares similarities with the ketogenic (keto) and Atkins diets, but with a crucial distinction. While keto and Atkins diets restrict carbohydrates, the carnivore diet eliminates all carbohydrates and other food groups, including fruits, vegetables, grains, nuts, seeds, and legumes.
Historical Context
The concept of a carb-free diet isn't entirely new. In the late 1700s, Scottish military surgeon John Rollo, MD, employed a meat-only diet to manage diabetes in his patients, observing that it effectively lowered their blood sugar levels. More recently, former orthopedic surgeon Shawn Baker, MD, popularized this eating style with his 2019 book, "The Carnivore Diet." The diet gained further traction through endorsements, including from comedian and podcast host Joe Rogan, who reported weight loss and increased energy after a 30-day meat-only experiment.
Navigating the First Week: A Detailed Guide
Preparing for the Transition
The initial step involves preparing your environment and mindset. Clearing your pantry and refrigerator of carbohydrate-containing foods can help minimize temptation. Creating a shopping list focused on animal-based products is essential.

Allowed and Restricted Foods
The carnivore diet's approved food list is concise, comprising exclusively animal products. Acceptable choices include:
- Red Meat: Steak, burgers, chuck roast
- Poultry: Chicken, lamb, pork
- Seafood: Salmon, trout, oysters, clams
- Organ Meats: Liver, oxtail
Foods to be consumed in limited quantities include cheese, eggs, heavy cream, milk, yogurt, bacon, sausage, and cured meats.
Conversely, any foods not derived from animals are strictly prohibited. This encompasses fruits, vegetables, grains, legumes, nuts, and seeds. While some variations of the diet allow cheese and other dairy products, these are typically limited due to potential inflammatory effects.
Potential Benefits and Claims
The carnivore diet is promoted for its potential weight loss benefits, as well as purported improvements in heart health, autoimmune conditions, blood sugar control, and mood. However, it's crucial to recognize that these claims are not consistently supported by rigorous scientific evidence.
One survey of over 2,000 individuals who had followed the carnivore diet for several months reported positive outcomes such as lower BMI, increased energy, better sleep, enhanced strength and endurance, and improved cognitive function. Notably, many participants with diabetes were able to reduce or eliminate their diabetes medication. However, this study relied on self-reported data, lacking objective measurements of nutrient levels or health status.

Potential Side Effects
The carnivore diet deviates significantly from the Dietary Guidelines for Americans, which emphasize the importance of carbohydrates for energy. Eliminating entire food groups can lead to nutrient deficiencies.
Commonly reported side effects during the initial phase of the carnivore diet include:
- Constipation: Due to the lack of fiber from vegetables.
- Diarrhea: Possibly resulting from the high-fat, high-protein content altering gut bacteria balance.
- Headaches, Nausea, and Lack of Energy: Potential symptoms as the body adapts to using fat for fuel.
Furthermore, the high saturated fat content of animal-based diets can raise LDL cholesterol levels, increasing the risk of heart disease and stroke. Processed meats, often included in the diet, can contribute to high blood pressure due to their high sodium content.
Personal Experience: A 30-Day Journey
One individual's account of their first 30 days on the carnivore diet, undertaken in support of their husband, provides valuable insights into the practical aspects of the diet. The couple had previously experimented with various food plans, including the Daniel Diet, intermittent fasting, Keto, and Brightline.
The husband sought a dietary approach to address weight gain, poor sleep, lack of motivation (potentially stemming from a post-COVID state), inflammation (manifesting as a Baker's Cyst), and a chronic lung infection. The wife, initially hesitant, became more enthusiastic as she learned about the potential for improved well-being beyond just weight loss.

Modified Approach
While the husband adhered to a strict carnivore diet, the wife adopted a modified version, incorporating full-fat yogurt, blueberries, and small amounts of cheese. This highlights the flexibility some individuals may find necessary to sustain the diet.
Shopping and Preparation
The couple prepared for the diet by creating a list of acceptable foods and planning meals for the week. They anticipated a higher grocery bill due to the increased meat consumption but were surprised to find it was actually lower than usual.
Goals and Observations
The individual set specific goals for the diet, including:
- Reducing coffee consumption
- Improving sleep quality without sleep aids
- Clearing up skin issues
- Eliminating alcohol
- Improving GI system function
- Achieving more consistent energy levels
- Improving mood and mental clarity
During the first week, she observed:
- A weight loss of 5 pounds (from 154 lbs to 149 lbs on day 6)
- Reduced bloating, indicated by her wedding ring fitting better
- Reduced coffee consumption
- Disrupted sleep patterns initially
- Two instances of consuming carbs to alleviate nausea
- Successful completion of a 10K run, albeit with nausea
- Two occurrences of hives
- More consistent energy levels
- Infrequent bowel movements, requiring laxatives
- A sense of calmness and improved mood
Addressing Challenges
The individual addressed challenges such as the lack of vegetables and fruit by adopting a modified approach, incorporating dairy and berries sparingly. She also emphasized the importance of electrolytes to avoid "keto flu," a common side effect of low-carbohydrate diets.
Week 2 Adjustments
In the second week, the individual focused on optimizing her supplement intake, adding cod liver oil capsules and beef organ capsules to address potential nutrient deficiencies and constipation.
Sample Carnivore Diet Menu and Recipes
A typical carnivore diet menu might include:
- Breakfast: Eggs and bacon
- Lunch: Burger patties
- Dinner: Salmon
Some carnivore diet-friendly recipes include:
- Scrambled eggs with turkey: Cooked turkey breast mixed with scrambled eggs.
- Salmon patties: Canned salmon mixed with bacon, eggs, and dill, formed into patties and cooked in butter.
- Carnivore chicken casserole: Rotisserie chicken blended with cream cheese, sour cream, cheddar cheese, and taco or Cajun seasoning, then baked.
Snack options include cheese sticks, hard-boiled eggs, salmon jerky, and sardines.
Is the Carnivore Diet Right for You?
The carnivore diet is a highly restrictive eating plan with potential benefits and risks. It may lead to weight loss and improvements in certain health markers, but it also carries the risk of nutrient deficiencies and other side effects.
It is crucial to consult with a healthcare professional or registered dietitian before starting the carnivore diet, especially if you have underlying health conditions or are pregnant or breastfeeding. They can help you assess the potential risks and benefits and determine if the diet is appropriate for your individual needs.
Additionally, it's important to be wary of fad diets promoted by non-health experts and to prioritize a balanced and sustainable approach to eating that meets your nutritional needs and supports your overall health.
