Paleo Diet: What to Eat, Benefits and Drawbacks

The paleo diet is an eating plan based on foods that early humans may have eaten before farming began: meat, fish, eggs, vegetables, fruit, nuts and seeds. It cuts out grains, pulses, dairy, refined sugar and processed foods. It can encourage more whole foods, but it is restrictive and removes some foods with proven health benefits.

Supporters say paleo eating helps with weight loss, energy and blood sugar. Critics point out that it excludes nutritious foods like wholegrains, lentils and yoghurt, and that it can be expensive. This guide looks at the origins, principles, possible benefits and drawbacks of the paleo diet, so you can decide if any part of it suits you.

What is the paleo diet?

Paleo is short for Palaeolithic, the Stone Age period that ended roughly 10,000 years ago, when humans began farming. The idea behind the diet is that our bodies are better suited to the foods our hunter-gatherer ancestors ate, and that modern farmed and processed foods contribute to health problems.

In reality, early humans ate very different diets depending on where and when they lived, and most foods we eat today, including vegetables and meat, have changed a lot through farming. So the modern paleo diet is best seen as a set of food rules inspired by the past rather than an exact copy of it.

What can you eat on the paleo diet?

Foods to eat	Foods to avoid
Meat, poultry and fish	Grains: wheat, rice, oats, barley, maize
Eggs	Pulses: lentils, chickpeas, beans, peanuts
Vegetables	Dairy: milk, yoghurt, laban, cheese
Fruit, including dates	Refined sugar and sweets
Nuts and seeds	Processed foods and most vegetable oils
Olive oil, avocado	Salt in large amounts

Some people follow a looser version that allows a little dairy, rice or pulses. This can make the diet more balanced and easier to maintain.

What are the possible benefits of the paleo diet?

Because it removes most processed foods, the paleo diet can lead to some healthy changes:

• Fewer ultra-processed foods: less sugar, salt and refined carbohydrates.
• More vegetables and fruit: which provide fibre, vitamins and antioxidants.
• Higher protein: which helps you feel full and may support weight loss in the short term.
• Possible improvements in blood sugar and blood pressure: some small, short-term studies have shown this, but larger, longer studies are needed.

Many of these benefits come from cutting processed foods and eating more vegetables, which you can do without following paleo strictly.

What are the drawbacks of the paleo diet?

It cuts out healthy food groups

Wholegrains and pulses are linked with a lower risk of heart disease and type 2 diabetes, and they are rich in fibre. Removing staples such as dal, chickpeas, oats and wholewheat chapati means losing valuable nutrients.

Risk of low calcium and vitamin D

Without dairy, it can be hard to get enough calcium for healthy bones. You would need to rely on foods such as leafy greens, almonds, sesame seeds and tinned fish with soft bones, and possibly a supplement if your doctor recommends it.

High red meat intake

Some people eat a lot of red and processed meat on paleo. Health bodies advise limiting red meat and processed meat because of links with bowel cancer.

Cost and practicality

Meat, fish, nuts and fresh produce can be expensive. The diet can also be difficult to follow at family meals, weddings and gatherings where rice, bread and sweets are central.

Not suitable for everyone

People with kidney disease, those who are pregnant, children and anyone with a history of disordered eating should not follow restrictive diets without medical advice.

How to take the best ideas from paleo

You do not need to follow paleo fully to benefit from its strongest ideas. Try these balanced changes:

• Cut back on sweets, sugary drinks, packaged snacks and processed meats.
• Fill half your plate with vegetables at most meals.
• Choose fish, eggs, chicken and pulses as your main proteins.
• Keep wholegrains, such as brown rice, oats and wholewheat roti, in sensible portions.
• Enjoy plain yoghurt or laban for calcium and protein.
• Use olive oil, nuts and seeds as healthy fats.

This approach is closer to the Mediterranean diet, which has stronger evidence for long-term health.

When to see a doctor or nutrition professional

• You have diabetes, kidney disease, heart disease or high cholesterol
• You take medicines for blood sugar or blood pressure, which may need adjusting
• You are pregnant, breastfeeding or planning a pregnancy
• You feel tired, constipated or unwell after changing your diet
• You find yourself cutting out more and more foods, or feel anxious about eating

Frequently asked questions

Is the paleo diet good for weight loss?

Some people lose weight on paleo, mainly because it cuts processed foods and increases protein and vegetables, which can reduce how much you eat. However, it is not more effective than other balanced approaches in the long term.

Can you eat rice on the paleo diet?

Strict paleo excludes all grains, including rice. Some people follow a relaxed version that includes small amounts of white rice. If you enjoy rice, you can keep it in a balanced diet.

What is the difference between paleo and keto?

Paleo focuses on which foods to eat, cutting grains, pulses and dairy. Keto focuses on keeping carbohydrates very low and fat high. Keto allows some dairy, while paleo allows more fruit and starchy vegetables.

Is the paleo diet safe long term?

There is limited long-term research. Strict versions may be low in fibre, calcium and vitamin D. If you want to follow it, ask a nutrition professional to help you plan it safely.
