Understanding the Reversion: Why do vegetarians start eating meat again?

5 min read

According to a 2014 study by Faunalytics, approximately four out of five vegetarians eventually resume eating meat. The decision to abandon a plant-based diet is a complex one, driven by a variety of health, social, and personal factors rather than a single reason.

Quick Summary

Former vegetarians often resume meat consumption due to a mix of nutritional deficiencies, unmanageable taste cravings, social and cultural challenges, and the inconvenience of maintaining a strict diet. Factors like health issues and the high cost of processed alternatives can also contribute to the decision to revert to an omnivorous diet.

Key Points

  • Nutrient Deficiencies: Inadequate intake of essential nutrients like Vitamin B12, iron, and zinc is a primary reason many revert from a vegetarian diet.

  • Intense Cravings: Powerful cravings for meat, often linked to evolutionary drives or emotional comfort foods from childhood, lead some back to an omnivorous diet.

  • Social Discomfort: Navigating social events and family meals can be a major challenge, causing feelings of isolation and making it easier to simply eat what others are eating.

  • Logistical Challenges: For some, the inconvenience and cost of maintaining a diverse and nutritious vegetarian diet, especially when relying on processed alternatives, is not sustainable.

  • Psychological Strain: The 'all-or-nothing' approach can lead to anxiety, stress, or trigger disordered eating patterns, making a more flexible, mindful approach healthier in the long run.

  • Focus on Flexibility: Many former vegetarians adopt a flexitarian approach, reducing meat consumption without adhering to a strict, unsustainable label.

  • Improved Well-being: Some people report feeling better and having more energy and mental clarity after mindfully reintroducing meat, particularly when addressing pre-existing deficiencies.

Health and Nutritional Motivations

One of the most frequently cited reasons for abandoning a vegetarian diet is health-related concerns, often stemming from nutrient deficiencies. While a well-planned vegetarian diet can provide all necessary nutrients, a poorly constructed one can lead to significant issues, such as chronic fatigue and poor energy levels. Many who return to eating meat report a noticeable improvement in their health after doing so.

Overcoming Nutritional Deficiencies

A significant portion of those who revert do so to address specific nutrient deficits. The absorption of certain vitamins and minerals is often more efficient from animal products than from plant-based sources.

  • Vitamin B12: Primarily found in animal products, B12 deficiency is a common risk for vegetarians and vegans and can lead to fatigue, weakness, and neurological problems. Many people report increased energy after reintroducing meat.
  • Iron: While plant-based foods contain iron (non-heme), it is less bioavailable than the heme iron found in meat. This can lead to iron deficiency, especially in women.
  • Zinc: Crucial for immune function, zinc absorption is less efficient from plant sources due to compounds like phytates.
  • Omega-3 Fatty Acids: Certain essential fatty acids are more bioavailable in animal products, and deficiencies can impact mood and overall health.

Satiety and Weight Management

Meat is a dense source of high-quality, complete protein, which can lead to increased feelings of fullness and sustained energy. Some former vegetarians explain that relying heavily on processed plant-based meat alternatives left them feeling unsatisfied and hungry, contrasting sharply with the satiety they feel from a meal with animal protein. This can also be a factor for those with a history of disordered eating, who may have used vegetarianism as a way to control their intake, but found it unsustainable.

Social, Cultural, and Emotional Factors

Beyond the physical aspects, social and cultural pressures play a significant role in many individuals' decisions to stop being vegetarian.

Navigating Social Situations

One of the biggest challenges for vegetarians is navigating social gatherings, family meals, and dining out. Being the 'only vegetarian' at a family dinner or a barbeque can lead to feelings of being an inconvenience or an outsider. Some former vegetarians feel liberated by no longer having to decline food offerings or explain their choices, allowing them to reconnect with friends and family over shared meals.

Reconnecting with Heritage and Comfort Food

Food is deeply tied to memory and cultural identity. Some revert to eating meat to reconnect with their heritage and the comfort foods they grew up with, especially after being vegetarian for many years. This could be due to a parent's illness or simply a desire to participate in cultural traditions tied to specific animal-based dishes.

Intense Taste Cravings

For some, the sheer pleasure and cravings for meat are too powerful to resist. The smell of a sizzling barbecue or a specific childhood favorite meal can trigger irresistible urges. This is often an emotional or psychological battle, as many feel conflicted about the ethical aspects of their choice.

Logistical and Financial Realities

The practicalities of maintaining a vegetarian diet can also lead to reverting, especially for those with busy lifestyles.

Convenience and Access

While vegetarianism is becoming more mainstream, it can still be inconvenient, particularly for those who travel or live in areas with limited access to diverse, whole-food plant-based options. The reliance on expensive, processed meat alternatives, rather than traditional legumes and whole grains, can also be an unsustainable path.

Cost Considerations

Despite some studies suggesting plant-based diets can be cheaper, many people find that building a nutritious vegetarian diet can be more expensive than reverting to meat. The high cost of processed alternatives and the potential need for nutritional supplements can add up, pushing some people back towards more affordable options.

Weighing the Differences: Vegetarian vs. Flexitarian

Some people don't fully revert to their old ways but instead become "flexitarian," a more flexible approach that includes some animal products. This mindset can be a sustainable middle ground that addresses some of the challenges of strict vegetarianism.

Factor Strict Vegetarianism Flexitarianism Return to Meat-Eating
Dietary Rules No meat, poultry, or fish. Primarily plant-based, with occasional meat or fish. Full inclusion of meat and animal products.
Nutrient Concerns Requires careful planning for B12, iron, zinc, etc. Easier to meet nutrient needs with occasional animal products. Lower risk of common plant-based deficiencies.
Social Ease Can be challenging at social events or family gatherings. Offers more flexibility and easier integration into social situations. Alleviates pressure and judgment related to food choices.
Convenience May require more meal prep and planning, limited options in some areas. Adapts more easily to travel and dining out. Generally the most convenient option in many societies.
Ethical Conflict Highest commitment to animal welfare and environment. Allows for balance between ethics and personal needs. May involve significant ethical re-evaluation for some.

Conclusion

The decision for former vegetarians to start eating meat again is a personal journey influenced by a mix of health, emotional, social, and practical factors. While the initial motivations for adopting the diet—often ethical or environmental—remain valid, the daily reality can present significant obstacles. Nutritional shortcomings, social pressure, and taste cravings can combine to make a strictly plant-based lifestyle unsustainable for some. Recognizing these challenges and understanding that dietary changes are a process rather than a permanent state can lead to a more balanced and forgiving approach to eating. For many, the endpoint isn't a return to a heavy meat diet but a shift toward a more mindful and moderate consumption of animal products. The key takeaway is that listening to your body and finding a sustainable, balanced diet is more important than adhering to a rigid label. For some, this means reintroducing meat slowly and mindfully.

What Dietitians Say to Expect When You Eat Meat Again

After years of being vegetarian, if you're reintroducing meat, here's what dietitians advise:

  • Experience digestive changes: Your gut may need time to adjust to the density of meat protein and fat, potentially causing initial bloating or constipation.
  • Boost energy levels: Increased intake of iron and vitamin B12 can help improve energy production and combat fatigue.
  • Feel more full: Meat's high protein content promotes satiety, which can help control appetite and reduce snacking.
  • Start slowly: Begin with small, lean portions a few times a week to allow your digestive system to adapt comfortably.
  • Prioritize whole foods: Regardless of diet, focusing on whole foods—both plant and animal-based—is key to better health.

Frequently Asked Questions

Yes, a significant percentage of vegetarians do not remain meat-free for life. A 2014 Faunalytics study found that approximately four out of five vegetarians eventually resume eating meat.

Common health problems include chronic fatigue, low energy levels, or other symptoms caused by deficiencies in nutrients like Vitamin B12, bioavailable iron, zinc, and Omega-3 fatty acids, which are abundant in meat.

Social and cultural factors play a large role. Individuals may feel social pressure from friends or family, struggle with limited dining options at restaurants or events, or miss cultural food traditions from their upbringing.

While it is possible to get all necessary nutrients from plants, it requires careful and educated planning. B12 is not naturally present in most plants, and non-heme iron from plants is not as easily absorbed as heme iron from meat, making supplementation or fortification necessary for many.

The cost of a vegetarian diet can vary greatly. While simple, whole-food plant-based diets using legumes and grains can be cheaper, a diet that heavily relies on highly processed meat alternatives can often be more expensive than a moderate meat-inclusive diet.

When reintroducing meat, some people experience temporary digestive issues like bloating or constipation as their body's digestive system readjusts. Many also report higher energy levels and increased satiety due to the high protein and nutrient content.

Yes, it is common and normal to crave meat, even after being vegetarian for many years. Cravings can be triggered by the smell of cooking meat, stress, or emotional factors related to nostalgia and comfort.

Dietitians generally recommend reintroducing meat slowly and mindfully. Starting with small portions of lean meat every few days allows your body to adjust gradually, minimizing potential digestive discomfort.
