What would happen if everyone in the world went keto?

The Basics of the Ketogenic Diet

The ketogenic diet, or keto diet, is a low-carb, high-fat diet that has gained popularity in recent years. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes efficient at burning fat for energy. While the keto diet has been praised for its potential weight loss benefits and improved mental clarity, what would happen if everyone in the world adopted this eating pattern?

Positive Effects on Health

1. Weight Loss: One of the main reasons people turn to the keto diet is for weight loss. By reducing carbohydrate intake, the body is forced to burn stored fat for energy, leading to weight loss. If everyone in the world went keto, obesity rates could potentially decrease, resulting in improved overall health.

2. Reduced Risk of Type 2 Diabetes: The keto diet has shown promise in managing and even reversing type 2 diabetes. By limiting carbohydrate intake, blood sugar levels stabilize, reducing the need for insulin. If the entire world followed a keto diet, the prevalence of type 2 diabetes could significantly decrease.

3. Improved Mental Clarity: Many individuals on the keto diet report improved mental clarity and focus. This is because ketones, produced during ketosis, are a more efficient source of energy for the brain compared to glucose. If everyone went keto, productivity levels could potentially increase, leading to a more efficient workforce.

Challenges and Considerations

1. Nutrient Deficiencies: The keto diet restricts many food groups, including fruits, whole grains, and legumes, which are important sources of essential nutrients. If everyone in the world went keto, there would be a need for careful planning and supplementation to ensure individuals receive all the necessary vitamins and minerals.

2. Environmental Impact: The keto diet relies heavily on animal products, such as meat, dairy, and eggs. If the entire world adopted this eating pattern, the demand for animal products would skyrocket, leading to increased environmental concerns. Livestock farming already contributes significantly to greenhouse gas emissions and deforestation, so a global shift to keto could exacerbate these issues.

3. Cultural and Social Implications: Food plays a significant role in cultural and social interactions. The keto diet may not align with certain cultural or religious practices that emphasize carbohydrate-rich foods. Additionally, social gatherings and events centered around food may become more challenging to navigate if everyone followed a strict keto diet.

Economic Impact

1. Agriculture and Food Production: The shift to a global keto diet would have a significant impact on agriculture and food production. Farmers would need to adapt their practices to meet the increased demand for animal products and low-carb vegetables. This could lead to changes in land use, crop selection, and farming techniques.

2. Food Industry: The food industry would also need to adapt to a world where everyone follows a keto diet. There would be a surge in demand for keto-friendly products, such as low-carb bread, snacks, and desserts. This could create new business opportunities and job growth in the food industry.

3. Healthcare Costs: While the keto diet may have positive effects on health, it is not suitable for everyone. Some individuals may experience adverse effects, such as nutrient deficiencies or increased cholesterol levels. If everyone in the world went keto, healthcare costs could potentially increase due to the need for specialized dietary guidance and monitoring.


The idea of everyone in the world going keto raises both exciting possibilities and significant challenges. While the potential health benefits, such as weight loss and reduced risk of type 2 diabetes, are promising, there are also concerns regarding nutrient deficiencies, environmental impact, and cultural implications. Additionally, the economic impact on agriculture, food production, and the healthcare industry would be substantial. Ultimately, the decision to adopt a keto diet on a global scale would require careful consideration and planning to ensure the well-being of individuals and the planet.
