What is the Paleo Diet?

The Paleo diet, often called the Caveman Diet, mimics the eating habits of ancient humans. It centres around the idea that for optimal health, we should eat more like our Paleolithic ancestors. 

This means the diet includes foods that could be hunted or gathered, such as lean meats, fish, fruits, vegetables, nuts, and seeds. The idea is to exclude processed foods, dairy, grains, and refined sugars—the typical culprits of modern-day health woes.

Paleo Diet Foods: What Can You Eat?

Beginning the Paleo diet means you’ll enjoy a rich variety of foods:

Lean Meats and Fish

These protein-rich foods are fundamental to the Paleo diet. Options like chicken, turkey, beef, lamb, and venison provide essential amino acids that aid in muscle repair and growth. Fish, particularly fatty varieties like salmon, mackerel, and sardines, offer high-quality protein and omega-3 fatty acids, which are crucial for heart and brain health.

Fruits and Vegetables

The Paleo diet emphasises a plentiful intake of fruits and vegetables, which are sources of vitamins, minerals, antioxidants, and fibre. These nutrients support a healthy immune system, aid digestion, and can reduce the risk of chronic diseases. Colourful vegetables and fruits—such as leafy greens, berries, carrots, and beets—not only make your plate more appealing but also ensure a diverse intake of beneficial compounds.

Nuts and Seeds

Nuts and seeds are excellent snacks or additions to meals. They provide healthy fats, proteins, and a variety of micronutrients like magnesium and zinc. Almonds, walnuts, flaxseeds, and pumpkin seeds are just a few options that can enhance your diet. They add crunch and flavour to salads, yoghurts, and other dishes while also contributing to satiety and energy levels.

Healthy Fats

The Paleo diet doesn’t shy away from fats; instead, it encourages the consumption of healthy fats which are essential for maintaining good health. Avocados, coconut oil, and extra virgin olive oil are prime sources of monounsaturated and saturated fats, supporting brain function and skin health. These fats are good for cooking and add a rich, satisfying flavour to meals.

What's Off the Menu?

While the Paleo diet offers a rich array of food choices, it also requires avoiding some common elements of the modern diet to stick to its principles:


Grains like wheat, oats, barley, and rice are excluded from the Paleo diet. The rationale is that grains are a product of modern agriculture and are often high in carbohydrates and can contain gluten, which many people choose to avoid for digestive health and inflammation reasons.


Beans, lentils, peanuts, and other legumes are not part of the Paleo diet. Although they are rich in protein and fibre, they also contain phytates and lectins, which are considered anti-nutrients that can interfere with the absorption of minerals and cause digestive issues.

Dairy Products

The Paleo diet excludes most forms of dairy, especially processed dairy products. The diet suggests that human adults do not necessarily need milk from other species, and many people are lactose intolerant. However, some adherents include ghee or grass-fed butter, which are lower in lactose and contain beneficial fats.

Processed Foods and Sugars

The exclusion of processed foods and refined sugars is perhaps one of the most impactful aspects of the Paleo diet. These foods are high in calories but low in nutritional value and can lead to weight gain, blood sugar instability, and other health issues. By avoiding these, the Paleo diet promotes a more natural, wholesome approach to eating, focusing on foods that are minimally processed.

How Does Paleo Promote Weight Loss?

Adopting a Paleo diet can significantly contribute to weight loss through several mechanisms. These include increased protein intake, the elimination of processed foods and sugars, and a high intake of dietary fibre. 

1. High in Protein

Protein plays a role in weight loss due to its ability to induce satiety and reduce overall calorie consumption. Foods rich in protein, such as lean meats, fish, and eggs, help keep you feeling full for longer periods, which minimises the likelihood of snacking on less healthy options between meals. 

Additionally, protein has a higher thermic effect compared to fats and carbohydrates. This means that your body expends more energy in digesting protein, which can boost metabolism and increase the number of calories burned throughout the day. Incorporating adequate protein into your diet can also help preserve muscle mass during weight loss, ensuring that your body burns fat instead of muscle.

2. Eliminates Processed Foods and Sugars

One of the foundational principles of the Paleo diet is the elimination of processed foods and added sugars, which are commonly linked to obesity and metabolic issues. Processed foods are often calorie-dense yet nutrient-poor, providing little nutritional benefit in return for their high caloric content. Additionally, they frequently contain high levels of sugars and unhealthy fats that can trigger insulin spikes and contribute to fat storage. 

By eliminating these foods, the Paleo diet helps to stabilise blood sugar levels and reduce the overall caloric intake, creating a favourable environment for weight loss. Avoiding these foods also reduces the risk of experiencing the energy dips and cravings that accompany blood sugar fluctuations, making it easier to adhere to a healthy eating plan.

3. Rich in Fibre

A diet rich in fruits and vegetables, as advocated by the Paleo diet, naturally increases your fibre intake. Fibre is essential for weight loss for several reasons. First, it adds bulk to your diet without adding extra calories, helping you feel full and satisfied after meals. This can reduce overall food intake and prevent overeating. 

Fibre also plays a role in maintaining a healthy digestive system, improving gut health, and supporting regular bowel movements, which helps in the efficient elimination of waste and toxins from the body. Furthermore, high-fibre foods typically require more chewing, which can slow down your eating pace, giving your brain time to register fullness, which further helps control your appetite.

Potential Challenges and How to Overcome Them

While the benefits are compelling, some might find the Paleo diet restrictive. Here’s how you can tackle common hurdles:

  • Limited Grains and Dairy: Explore Paleo-friendly recipes that use alternative ingredients like almond flour and coconut milk.
  • Social Dining: When eating out, choose simple dishes like grilled proteins and salads.
  • Initial Fatigue: As your body adjusts to fewer carbs, you might feel tired. Ensure you’re eating enough calories, especially from fats and proteins.

Frequently Asked Questions About the Paleo Diet for Weight Loss

Can you lose weight fast on a Paleo diet?
