The Lion Diet is a highly restrictive meat-based elimination diet. Its purpose is to help identify foods that may negatively impact your health. Proponents claim it can improve issues like inflammation, fatigue, and autoimmune conditions. However, its unsustainable nature and high saturated fat content make it controversial.

In this article, we’ll examine the Lion Diet, how it works, the foods it allows, its potential benefits and risks, and whether it’s worth trying.


Diet Review Scorecard

  • Overall Score: 1.25/5
  • Weight Loss: 1/5
  • Healthy Eating: 0/5
  • Sustainability: 1/5
  • Whole Body Health: 1.5/5
  • Nutrition Quality: 3/5
  • Evidence-Based: 1/5

BOTTOM LINE: The Lion Diet eliminates all foods except meat from ruminant animals, salt, and water. While it might temporarily help identify food sensitivities, it is unsustainable and lacks essential nutrients.


What Is the Lion Diet?

The Lion Diet is an extreme elimination diet focusing on only three components:

  1. Meat from ruminant animals (e.g., beef, lamb, goat, bison).
  2. Water.
  3. Salt.

This eating plan was developed by Mikhaila Peterson, a lifestyle blogger who claimed the diet improved her autoimmune and mental health symptoms.

The Lion Diet builds on the principles of the carnivore diet but takes them further by narrowing food options to just ruminant meats. Advocates suggest that this limited diet helps reduce inflammation and improve energy by removing potential dietary triggers.


How It Works

The Lion Diet involves eating only salt, water, and meat from ruminant animals. The idea is to strip your diet down to these elements to help your body reset.

Here’s how it works:

  1. Elimination Phase: Remove all foods except the three allowed ingredients until your symptoms improve.
  2. Reintroduction Phase: Gradually reintroduce one food at a time to determine which foods trigger negative reactions.

Some followers also incorporate intermittent fasting, eating one large meal daily or fasting for 16–20 hours. However, this is optional.


Foods to Eat and Avoid

Foods to Eat

  • Meat from ruminant animals: beef, lamb, bison, goat, deer.
  • Water.
  • Salt.

Foods to Avoid
The diet excludes everything else, including:

  • Fruits and vegetables.
  • Grains (e.g., bread, rice, pasta).
  • Legumes (e.g., beans, lentils).
  • Nuts and seeds.
  • Dairy products.
  • Poultry and seafood.
  • Oils and fats (e.g., olive oil, butter).
  • Beverages other than water.

Can the Lion Diet Help With Weight Loss?

Although weight loss is not the primary goal of the Lion Diet, it can lead to weight loss due to its limited food options. By eliminating calorie-dense and processed foods, you may naturally consume fewer calories.

However, this calorie deficit may also slow your metabolism and cause nutritional deficiencies over time, making it harder to maintain weight loss long-term.


Benefits of the Lion Diet

While research specifically on the Lion Diet is lacking, its proponents claim it offers benefits similar to those of other elimination diets:

  1. Reduced Inflammation: Eliminating potential triggers may help ease inflammatory conditions.
  2. Symptom Identification: Gradual reintroduction of foods helps identify triggers for digestive or autoimmune issues.
  3. Simplification: With just three ingredients, meal planning becomes straightforward.

Studies on elimination diets suggest they may help manage conditions like irritable bowel syndrome, rheumatoid arthritis, and food allergies.


Potential Downsides

Despite its claimed benefits, the Lion Diet poses several risks:

  1. Nutritional Deficiencies: Eliminating fruits, vegetables, and other food groups leaves the diet lacking in fiber, vitamins, and minerals.
  2. High Saturated Fat: Ruminant meats are high in saturated fat, potentially raising LDL (bad) cholesterol levels.
  3. Unsustainability: The extreme restrictions make it challenging to follow and impractical for long-term use.
  4. Risk of Disordered Eating: The rigid guidelines may promote unhealthy relationships with food.
  5. Low Calorie Intake: Insufficient calories can lead to fatigue, dizziness, and hormonal imbalances.

Should You Try the Lion Diet?

For those exploring elimination diets, there are safer and more balanced alternatives. For example:

  • Low-FODMAP Diet: Helpful for managing irritable bowel syndrome.
  • Targeted Elimination Diets: Focus on eliminating specific food groups (e.g., gluten, dairy) instead of everything.

If you suspect food sensitivities, consult a healthcare professional before starting a restrictive diet like the Lion Diet. They can guide you through healthier and more effective methods of identifying triggers.


The Bottom Line

The Lion Diet simplifies eating to three elements: ruminant meat, salt, and water. While it may temporarily help identify food sensitivities, its extreme restrictions make it nutritionally inadequate, unsustainable, and potentially harmful.

Before embarking on any elimination diet, seek professional advice to ensure your health is prioritized.
