Paleo Diet Benefits
While every person is unique and there is no one-size-fits-all diet, there are many reported and studied paleo diet benefits that are worth discussing. In this article, I will look at some of them.
Focusing on vegetables, meat, fish, eggs, fruit, nuts and seeds – all of which are nutrient-dense foods – it’s no surprise that the Paleo diet has so many positive effects on one’s health and wellbeing.
Below is a list of known benefits that I have collated from my readers and program participants, existing studies, books and articles. I talk about paleo as a nutrient-dense diet, its effect on weight loss and digestion, share my personal experience and even look at some side effects you should know about.
This is just a simple overview and if you’re after more geeky science reading, check out the list of science and research on Robb Wolf’s website.
You Eat Unprocessed, Real food
This is the #1 thing I love about the paleo diet. It focuses on real, whole foods shunning most processed ingredients and anything from the junk aisle of the supermarket. Therefore, you automatically eliminate a whole range of preservatives, hidden sugars, sodium, additives, colouring, and artificial flavours. This means fewer toxins and chemicals in your body.
Plus, the focus of the diet is on the quality and sources of the food – grass-fed beef, wild fish, free-range eggs and organic produce when possible – which means you get in more nutrients, the food tastes better and you support good farming practices. See what you can eat on the paleo diet here.
Paleo Diet Is Rich In Nutrients
One of the misconceptions about the Paleo diet is that because you eliminate things like grains, legumes and most dairy, you are going to miss out on nutrients.
On the contrary, by consuming more nutrient-dense animal protein, seafood and eggs and replacing refined pasta, bread and rice with more vegetables, healthy fats, nuts, seeds, berries and fruit, you are actually going to consume more minerals and vitamins.
Plus, by avoiding gut-irritating grains and legumes, most people experience improved gut health and increased nutrient absorption.
Like with any diet, it is easy to lose balance so it’s important to eat a variety of protein, vegetables and fats rather than focusing on the same foods over and over again. On average, when done right, the paleo diet provides all the nutrients you need.
Paleo & Weight Loss
The Paleo diet is naturally lower in carbohydrates and sugar than most traditional Western diets. This helps to regulate metabolism, lowers blood sugar, improves gut health and reduces systemic inflammation.
Aided by better sleep and stress management – both key paleo lifestyle goals – these changes help to burn off stored body fat naturally and sustainably.
Most people experience weight loss and muscle growth while eating a paleo diet and keeping an active lifestyle. You can expect to lose 1-2 lb / 0.5 -1kg per week, depending on your starting weight, height and gender. For me personally, paleo has been great for keeping my healthy weight for the past 6-7 years without feeling like I deprive myself (read more about my personal approach below).
Improved Digestion & Reduced Bloating
The Paleo diet avoids many foods that contain compounds known to negatively affect the digestive tract.
For many people, the culprits of their digestive issues include excess sugar, dairy, legumes and gluten. These foods are excluded from the paleo diet, resulting in improved symptoms.
Plenty of plant fibre from vegetables and fruit ensures the gut flora is kept in tip-top shape and most people report improvements to their toilet habits (if you know what I mean).
Personally, I have noticed that my digestion improves significantly when I eat as close to the paleo guidelines as possible, and this is why I will use it as a reset diet whenever I feel like I’ve had way too much pasta, and legumes or dairy and feel bloated or gassy.
Satiation & Hunger Control
Familiar with the feeling of hangry? It’s the combination of hungry+angry, which is a common symptom for many people suffering from acute or chronic hyperglycemia. This also happens when the blood sugar drops and the person gets a rapid onset of hunger accompanied by irritability, fatigue, disorientation, and a foggy mind.
Paleo meals consist of more protein and fat, which are both very satiating and provide long-lasting energy.
Being lower in carbohydrates, the paleo diet teaches the body to use those macronutrients more efficiently instead of relying on glucose from carbohydrates for fuel.
Think of the days when you eat toast with jam or a muffin and a coffee for breakfast and then feel ravenous just a couple of hours later, resulting in needless snacking before lunch. When you eat protein and fat-rich paleo breaky of eggs and avocado, you can be happily satiated until 1 pm.
In addition, the carbohydrates you do consume, come from fibre-rich vegetables and fruit, meaning that the glucose is utilised more slowly. As a result, the blood sugar levels stay stable and you rarely experience energy drops; hunger develops gradually without the crazy mood swings.
Paleo Diet Is Rich In Healthy Fats
For many years, we’ve been told that fat (especially saturated fat) is bad for us. Yet, our body needs fat to thrive.
Fat is essential for maintaining healthy arteries, brain function, and healthy skin, as well as decreasing systemic inflammation. We are finally starting to understand that dietary fats are in fact very healthy, especially when they come from the right sources.
Paleo diet encourages consumption of good fats: saturated fat from grass-fed meat, wild fish and seafood, ghee, and coconuts; lots of monounsaturated fat from olive oil, avocado, nuts and seeds; and, a small number of polyunsaturated fats.
A healthier ratio of omega-3s to omega-6s fatty acids is commonly observed in those following the paleo diet (less processed food and hydrogenated, vegetable oils + more fish and leafy greens) and evil trans fats are very rare.
I laugh when I think about how scared I used to be of anything fatty. I only bought low-fat cheese, skim milk and non-fat yoghurt (full of sugar!) and I even remember cooking some ham in water in a frying pan instead of using bacon. I feel like I missed out on so much goodness. Now I embrace oily fish, olive oil, butter and avocados, and full-fat Greek yoghurt.

My Personal Experience
I used to follow a paleo diet for many years. I had regular health checkups and full blood work and I’ve always had great results from eating more or less paleo, staying active and spending time outdoors.
I always notice I have a lot more energy when I eat closer to the paleo framework. I wake up feeling good and chirpy, I sleep better and deeper, my skin is clearer, and I have so much more mental clarity.
I no longer follow the paleo diet but I do use it as a detox or a cleanse from time to time because it does make you feel pretty amazing.
I always recommend trying the paleo diet for 30 days as a way to reset and find out how you feel using this dietary approach. You can still experience many of the below benefits if you use Paleo principles as a guide rather than strict rules.
Are There Any Negative Effects?
Many people who start following a paleo diet report that they experience initial detox and readjustment symptoms such as headaches, fatigue and digestive changes. These usually pass within 5-7 days.
Some even experience flu-like symptoms (known as the carb-flu) when their body consumes fewer carbohydrates. Staying hydrated and increasing sodium will help to reduce such symptoms.
Some might experience digestive issues due to increased fibre consumption (e.g. eating more vegetables than they used) or from introducing fermented foods. Increased fat consumption might initially affect stool texture and regularity. Most digestion-related symptoms tend to level out after a couple of weeks.
Carbohydrate intake is another factor that can vary between individuals. Some women may experience hormonal imbalances if they don’t consume enough carbohydrates, in which case an increase in starchy vegetables and fruit (and even rice) is recommended. Others tend to do better with fewer carbs.
Overall, paleo is a dietary framework that anyone can build upon. It’s not meant to fix every issue and it’s not designed to suit everybody. You have to try it for a few weeks and see how YOU feel.
How Long Before I See Results?
Based on the hundreds of testimonials from the people who have done my paleo plan, most report experiencing increased energy, fewer cravings, and better sleep with the first week.
Weight loss is usually reported after 7 days and continues steadily until you hit your ideal, healthy weight. Improvements to digestion, gut health and inflammation can take anywhere between 1-2 weeks to a few months, depending on the base condition.
Some people tend to overindulge in paleo desserts or too many nuts and dried fruit or their caloric intake or portion sizes are way too big for their energy expenditure.
These factors can set you back when it comes to weight loss. Others might have severe underlying issues such as autoimmune conditions and microbiome imbalances, which require further dietary and lifestyle fine-tuning.
Is The Paleo Diet For Me?
Well, the only person who can answer that question is you.
What I can tell you is that the paleo diet has done amazing things for a lot of people and it is a great way to eat more nutrient-dense foods. I think that the paleo label can deter some people from trying this way of eating, but I seriously don’t see any downsides in giving it a go.
While I no longer eat paleo, I am extremely grateful for what it has taught me about nutrition and about my own body. I want more people to learn what I have and that’s why I made my paleo program completely free!
And, if you don’t want to commit to paleo 100%, why not use some of its principles as starting points: cutting out junk food, eating more veggies, avoiding refined sugar and hydrogenated oils/margarine. Even these small changes will make a big difference in how you feel.
