Keto Vs Paleo: Which Diet Trumps The Other?

The paleo and keto diets are two of the most popular wellness trends globally, and both claim to be inspired by the presumed eating habits of our caveman ancestors. The paleo diet focuses on whole foods, while the keto diet emphasises a low-carb, high-fat intake to induce ketosis. Both diets are restrictive and can be challenging to maintain in the long term. While paleo is more flexible and focuses on lifestyle practices, keto is more prescriptive and centred on macronutrient distribution. Both diets have been shown to be effective for short-term weight loss, but more research is needed to determine their long-term efficacy.

The keto diet is a high-fat, low-carb, moderate-protein diet

The keto diet is a popular diet that has gained traction due to its potential benefits for weight loss and blood sugar control. It typically limits carbs to 20-50 grams per day, with less than 5% of energy intake coming from carbohydrates. The body usually uses glucose, a carbohydrate, as its energy source. However, when there is a very low intake of carbohydrates and glucose is unavailable, the body enters a metabolic state called ketosis, where it breaks down fat for energy.

The keto diet is considered restrictive and can be challenging to maintain in the long term. It may also cause side effects, such as increased cholesterol levels and constipation. It is not suitable for everyone, and some people may need to avoid it, including pregnant women, people with diabetes, and those with a history of kidney stones.

The keto diet includes a variety of animal proteins, dairy, vegetables, plant-based foods, and fats and oils. Here is a list of foods that can be consumed on a keto diet:

• Fish and shellfish: salmon, shrimp, crab, oysters, octopus, sardines, mackerel
• Meat and poultry: fatty meat, grass-fed meat, beef, pork, chicken
• Eggs
• Dairy: cheese, plain Greek yogurt, cottage cheese, cream, half-and-half, butter, unsweetened plant-based milk (soy, almond, coconut)
• Green leafy vegetables: spinach, kale, collard greens, salad greens, cooking greens, herbs
• High-fat veggies: avocados, olives
• Other non-starchy vegetables: summer squash, zucchini, cauliflower, spaghetti squash, jicama, turnips, peppers
• Nuts and seeds: almonds, pumpkin seeds, sunflower seeds, peanuts, chia seeds, hemp seeds
• Other plant-based foods: berries (raspberries, strawberries, blackberries, blueberries), shirataki noodles, dark chocolate and cocoa powder, olive oil, avocado oil, coconut oil
• Beverages: unsweetened coffee, tea, sparkling water

The keto diet can be adapted to meet different needs and goals. Here are some variations of the keto diet:

• Standard Keto Diet: The most common approach, with 75% of calories from fat, 20% from protein, and 5% from carbs.
• Strict Keto Diet: Used for epilepsy treatment, with 90% of calories from fat, 6% from protein, and 4% from carbs.
• Targeted Keto: For athletes to improve performance, following the standard keto diet and adding carbs 30-45 minutes before exercise.
• High-Protein Keto Diet: For bodybuilders or older people, with 30% of calories from protein, 65% from fat, and 5% from carbs.
• Cyclical Keto Diet: Also known as keto cycling, involves cycling in and out of keto, usually with five days of keto followed by one or two days with more carbs.
• Lazy Keto Diet: A simpler version of the keto diet, where only carbs are tracked, with a focus on keeping carb intake low.
• Mediterranean Keto Diet: Combines standard keto macros with Mediterranean diet elements like fatty fish and olive oil, emphasizing monounsaturated fatty acids and omega-3s.
• Keto 2.0: A less restrictive version with 50% fat, 30% protein, and 20% carbs, allowing for more variety in carbs and leaner protein sources.
• Dirty Keto: Focuses on convenience, with macros coming from any type of food, including highly processed and prepackaged meals.
• Clean Keto: Emphasizes organic and "healthy" versions of foods, with a focus on whole plant foods and healthy fats.

The paleo diet is less restrictive than keto

The paleo diet focuses on eating foods that were available to early humans in the Paleolithic era, such as meat, fish, fruits, vegetables, nuts, and seeds. It is believed that modern food systems and processing techniques are damaging to human health, so the paleo diet eliminates grains, legumes, processed sugar, and most dairy. However, paleo dieters are allowed to consume some unrefined sweeteners, such as raw honey, maple syrup, and coconut sugar.

The keto diet, on the other hand, is a very low-carb, moderate-protein, and high-fat diet. The primary goal of keto is to induce ketosis, a metabolic state where the body uses fat instead of carbohydrates as its primary energy source. To achieve ketosis, dieters must restrict their carbohydrate intake to less than 5% of their total calories, which is a challenging and inflexible requirement.

The paleo diet is more flexible in terms of food choices. While it restricts some carb sources, it is not necessarily a low-carb diet like keto. Paleo dieters can still consume carbs from whole food sources such as fruits, vegetables, and unrefined sweeteners. In contrast, the keto diet restricts all rich sources of carbohydrates, including starchy vegetables, most fruits, grains, sweeteners, and legumes.

The paleo diet also has a strong focus on lifestyle practices, exercise, and total body wellness. It encourages short, intense periods of exercise, as well as yoga and meditation for stress reduction. While the keto diet may be prescribed by a doctor for certain health conditions, it does not have an associated ideology or lifestyle component beyond choosing healthy food sources.

The paleo diet is generally considered a healthier option for most people due to its flexibility and the variety of nutritious options it offers. It is also easier to maintain in the long term, making it a more sustainable choice.

Paleo focuses on whole foods, keto on macronutrients

The paleo and keto diets have gained popularity for their ability to promote weight loss, fat reduction, and improved metabolism. While they share some similarities, they have distinct purposes.

The paleo diet, often called the "caveman diet", aims to mimic the eating patterns of our ancestors. It focuses on eating whole, natural foods while avoiding anything processed or agricultural, such as grains, legumes, and dairy. Paleo dieters generally don't count calories or macros but focus on eating whole, healthy foods.

On the other hand, the keto diet focuses on managing macronutrients (carbs, fat, and protein) to push the body into ketosis, a metabolic state where the body uses calories from fat instead of carbs for energy. To achieve ketosis, the keto diet requires strict macro-nutrient ratios, typically with high fat, low carb, and moderate protein.

In summary, paleo focuses on eating intuitively and choosing whole, natural foods, while keto emphasizes strict macro-nutrient ratios to induce ketosis. Paleo dieters have more flexibility in their food choices, while keto dieters need to carefully track their macro intake to stay within the set range of carbs, protein, and fat.

Both diets are effective for short-term weight loss

Both the keto and paleo diets are effective for short-term weight loss. While the keto diet focuses on a very low-carb, high-fat, and moderate-protein eating pattern, the paleo diet is based on the idea of eating only foods that were available to early humans to promote optimal health.

The keto diet restricts carbohydrates to less than 5% of energy intake, which is typically less than 50 grams per day. This restriction causes the body to enter a metabolic state called ketosis, where it breaks down fat for energy instead of carbohydrates. The paleo diet, on the other hand, does not focus on counting carbs, protein, or fat. It eliminates grains, legumes, dairy, and most processed foods while emphasizing whole foods.

Despite their differences, both diets have been shown to be effective for weight loss in the short term. A study on postmenopausal obese women following the paleo diet showed a 12.6% weight loss after 12 months. Similarly, studies on low-carb, high-fat diets like keto have demonstrated consistent short-term weight loss.

However, it is important to note that long-term studies on the effectiveness of these diets are lacking. As with most weight-loss diets, results are seen quickly in the short term, but it is questionable how long individuals can continue following the diet and maintain the results. Additionally, both diets are highly restrictive and can be challenging to maintain in the long term.

In conclusion, while both the keto and paleo diets can lead to short-term weight loss, it is unclear if they are effective for sustained, long-term weight loss. Individuals should consider their own needs, preferences, and sustainability when deciding between these two diets.

Keto is more difficult to maintain than paleo

The keto and paleo diets are both popular options for people looking to lose weight or improve their overall health. However, keto is more difficult to maintain than paleo due to several factors.

Firstly, keto places a heavy emphasis on macronutrient distribution, requiring careful planning and control to achieve and maintain ketosis. This metabolic state, where the body uses fat instead of carbohydrates for energy, demands strict compliance with a low-carbohydrate intake. Paleo, on the other hand, does not require such precise tracking of macronutrients, offering more flexibility in food choices.

Secondly, keto is less adaptable to varied social situations due to its restrictive nature. It eliminates many food groups, including grains, legumes, fruits, starchy vegetables, and dairy. Paleo also restricts certain food groups but allows for more whole-food sources of carbohydrates, such as fruits, vegetables, and unrefined sweeteners.

Additionally, keto's lack of flexibility can make it challenging to obtain adequate nutrients due to the limited food options. Paleo, with its focus on whole foods, may provide a wider variety of nutritious options.

Furthermore, keto may not be well-tolerated by everyone and may not suit everyone's lifestyle or dietary preferences. Paleo, on the other hand, is often seen as a lifestyle rather than just a diet and is considered easier to stick to in the long run.

Lastly, keto can be labour-intensive, requiring the weighing and tracking of food to maintain ketosis. Paleo, while still requiring some adjustments, may be more manageable in this regard.

In conclusion, while both diets have their advantages and can be effective for weight loss, keto is generally more difficult to maintain than paleo due to its strict compliance, lack of flexibility, and challenging nutrient adequacy.
