Popular Diets Explained: Mediterranean, Paleo, Keto, Gluten-Free, AIP & Intermittent Fasting

A practical Broth & Co guide to choosing an eating pattern that supports nutrition, gut health, metabolic wellbeing and real life.

 

Key takeaways

The most useful eating pattern is one that provides enough nutrition, includes foods you enjoy, supports your goals and can be repeated. Mediterranean, Paleo, Keto, gluten-free, AIP, low FODMAP and intermittent fasting approaches differ, but the strongest versions usually prioritise whole foods, protein, vegetables, healthy fats, fibre, hydration and fewer ultra-processed foods.

Choosing an Eating Pattern Without the Confusion

Nutrition advice can feel noisy. One person recommends Mediterranean eating, another prefers keto, and someone else feels best with gluten-free, fasting or an elimination-style approach.

Rather than turning diet labels into identities, it is more useful to ask what the pattern actually helps you do. Does it support adequate nutrition? Does it include enough protein, vegetables, fibre and healthy fats? Does it fit your appetite, culture, schedule, family life and health needs?

For most people, the foundation is not a label. It is a repeatable routine built around food quality, protein, plants, hydration, sleep and movement. Food First: 10 Daily Habits for Gut Health, Energy & Long-Term Wellbeing and Good Health Starts on Your Plate are useful starting points.

Quick Comparison

Diet style

Main idea

Best suited to

Mediterranean

Vegetables, legumes, fruit, olive oil, fish, whole grains, herbs and shared meals.

Families, everyday health, cardiovascular wellbeing, healthy ageing and long-term sustainability.

Paleo

Whole foods with meat, fish, eggs, vegetables, fruit, nuts and seeds while excluding grains, legumes and dairy.

People who enjoy higher-protein, whole-food eating and want fewer packaged foods.

Keto

Very low carbohydrate, higher fat and moderate protein.

People working with a practitioner on specific metabolic goals or who prefer very low-carbohydrate patterns.

Gluten-free

Removes wheat, rye, barley and other gluten-containing foods.

People with coeliac disease, gluten sensitivity or professional advice to avoid gluten.

AIP

Temporary elimination and reintroduction approach.

People undertaking guided food-sensitivity or autoimmune-related investigations.

Low FODMAP

Temporary reduction and reintroduction of certain fermentable carbohydrates.

People working through digestive tolerance with professional guidance.

Intermittent fasting

Focuses on meal timing rather than a specific food list.

People who prefer structured eating windows and can still meet nutrition needs.

 

Why People Follow Different Diets

People choose dietary approaches for many reasons: metabolic health, digestive comfort, food intolerances, athletic performance, body composition, family history, energy, culture, convenience and general wellbeing.

Different approaches can work for different people because they change the day-to-day pattern of eating. They may increase home cooking, reduce ultra-processed foods, improve protein intake, add vegetables or make meals feel more structured.

The strongest approach is the one that improves food quality without making life unnecessarily restrictive.

The Mediterranean Diet

The Mediterranean diet is one of the most researched eating patterns in the world. It is based on traditional dietary patterns from countries around the Mediterranean Sea and is known for variety, flavour and sustainability.

Emphasised foods

Useful considerations

Vegetables, fruit, legumes, whole grains, olive oil, fish, seafood, nuts, seeds, herbs and spices.

Works well for families and long-term routines because it is flexible rather than highly restrictive.

 

It is commonly associated with cardiovascular health, metabolic wellbeing, dietary diversity and healthy ageing. For a deeper comparison, see Keto vs Paleo vs Mediterranean Diet and The Mediterranean Diet for Brain Health.

The Paleo Diet

The Paleo diet focuses on whole foods such as meat, fish, eggs, vegetables, fruit, nuts and seeds while excluding grains, legumes, dairy and many highly processed foods.

Many people like Paleo because it can increase protein and vegetables while reducing packaged foods. The main consideration is that excluding grains, legumes and dairy can reduce dietary variety if meals are not planned carefully.

A well-planned Paleo-style routine still needs enough fibre, calcium-rich foods or suitable alternatives, healthy fats and plant variety.

The Ketogenic Diet

The ketogenic diet is a very low-carbohydrate, higher-fat eating pattern. It is usually built around meat, fish, eggs, healthy fats and non-starchy vegetables while limiting bread, rice, pasta, most grains, many fruits and sugary foods.

Keto can be difficult to maintain long term and requires careful planning to support fibre, micronutrients and digestive wellbeing. It is best approached thoughtfully, especially for people with medical conditions, children, pregnancy, breastfeeding, high training loads or a history of restrictive eating.

Gluten-Free Diet

A gluten-free diet removes gluten-containing grains, including wheat, rye and barley. It is medically required for people with coeliac disease and may also be used by people with identified gluten sensitivity or professional advice.

Gluten-free eating can still include vegetables, fruit, meat, fish, eggs, rice, quinoa, buckwheat, legumes, nuts and seeds. The important point is that gluten-free does not automatically mean more nutritious. Many gluten-free packaged foods are still highly processed.

If gluten is removed, it is worth paying attention to fibre, B vitamins, iron and overall dietary variety.

Gluten-Free and Casein-Free

A gluten-free and casein-free approach removes both gluten-containing grains and dairy proteins. Some people explore this when food sensitivities are being investigated, but it can remove several useful food groups at once.

If someone is avoiding both gluten and dairy, nutrient adequacy matters. Calcium, protein, iodine, B vitamins and fibre should be planned from other foods or suitable alternatives.

Autoimmune Protocol (AIP)

The Autoimmune Protocol is an elimination and reintroduction-style dietary approach. It usually begins by removing grains, dairy, legumes, eggs, nuts, seeds, nightshade vegetables and processed foods, while emphasising vegetables, quality protein, seafood, healthy fats and bone broth.

AIP is one of the more restrictive approaches, so it is usually best used as a structured temporary process rather than a permanent lifestyle. Reintroduction is an important part of learning personal tolerance and rebuilding dietary variety.

Low FODMAP Diet

The low FODMAP diet is a structured approach that temporarily reduces certain fermentable carbohydrates found in some fruits, vegetables, dairy products and wheat-based foods.

It is not designed as a lifelong diet. The reintroduction phase is essential because the goal is to identify personal tolerance while keeping the broadest diet possible.

Because the approach can be restrictive and technically detailed, many people benefit from professional guidance.

Intermittent Fasting

Intermittent fasting focuses on when you eat rather than prescribing one specific food list. Common approaches include 12:12, 14:10 and 16:8 eating windows.

Meal timing can help some people create structure, but food quality still matters. Fasting does not replace the need for protein, vegetables, fibre, healthy fats and enough overall nutrition.

Anti-Inflammatory Eating

Anti-inflammatory eating is less a single diet and more a pattern that emphasises vegetables, fruit, fish, extra virgin olive oil, herbs, spices and minimally processed foods while keeping ultra-processed foods, excess sugar and refined carbohydrates occasional.

Mediterranean-style eating is one of the clearest examples of this pattern. It is practical because it focuses on foods to include, rather than only foods to avoid.

What Successful Eating Patterns Have in Common

Despite their differences, the most practical eating patterns usually share several foundations.

·       More vegetables and fruit.

·       Adequate protein across the day.

·       Healthy fats such as olive oil, nuts, seeds, avocado or oily fish.

·       Fibre-rich foods where tolerated.

·       Less reliance on ultra-processed foods.

·       More home cooking and meal awareness.

·       Enough flexibility to fit real life.

Where Bone Broth Fits

Bone broth is versatile because it is a savoury whole food rather than a diet label. It can fit within Mediterranean-style meals, Paleo meals, lower-carbohydrate meals, intermittent fasting routines, AIP-style cooking and everyday whole-food nutrition.

Broth & Co bone broth provides approximately 5 g of naturally occurring protein per serve, together with collagen-derived amino acids including glycine, proline and glutamine. It can be enjoyed as a warming beverage, between meals, as a soup base or within recovery-focused nutrition.

Which Diet Is Best?

The most useful eating pattern is one that supports your goals, provides adequate nutrition, includes foods you enjoy, fits your lifestyle and can be maintained long term.

For many people, that means focusing less on diet labels and more on core habits: whole foods, adequate protein, plenty of vegetables, healthy fats, quality sleep, regular movement and a routine that can survive busy weeks.

Stress and sleep also shape appetite, energy and food choices. Nutrition for Stress Resilience: 10 Foods That Support Mood, Focus & Nervous System Health is a helpful companion article.

Frequently Asked Questions

Which diet is healthiest?

For many people, a Mediterranean-style pattern is one of the most balanced and sustainable options because it includes vegetables, fruit, legumes, olive oil, fish, herbs and whole foods. The best choice still depends on individual needs, preferences and circumstances.

Is keto better than Paleo?

Neither is universally better. Keto is very low carbohydrate, while Paleo focuses on whole foods and excludes grains, legumes and dairy. The better fit depends on goals, preferences, tolerance and whether the pattern can be maintained safely.

Is a gluten-free diet healthier?

Not automatically. Gluten-free eating is medically required for people with coeliac disease and may suit people with identified sensitivity, but gluten-free packaged foods can still be highly processed.

What is the Autoimmune Protocol diet?

AIP is a temporary elimination and reintroduction approach that removes several food groups at first, then reintroduces foods systematically to explore individual tolerance.

Can bone broth fit into multiple diets?

Yes. Bone broth can fit into Mediterranean, Paleo, lower-carbohydrate, AIP-style, fasting and whole-food nutrition routines as a savoury drink, soup base or cooking ingredient.

Do I need to follow a named diet?

No. Many people do well with a flexible food-first routine that includes protein, vegetables, healthy fats, fibre, hydration and meals they enjoy.

Summary

Nutrition trends will continue to change, but the fundamentals remain surprisingly steady: whole foods, nutrient density, adequate protein, colourful plants, healthy fats, hydration, movement, sleep and consistency.

Whether someone follows Mediterranean, Paleo, Keto, gluten-free, AIP or intermittent fasting principles, long-term wellbeing is usually built through practical habits that can be repeated.
