The Paleo Diet: Does the Caveman Lifestyle Work?

July 30, 2014

Susannah Taylor, Editor-in-Chief of online health and beauty magazine Get The Gloss asks whether the caveman diet is the way to go…

Over the last few years, whenever I have questioned top personal trainers, nutritionists or athletes on how they eat, most of them have responded not with the 5:2, the Dukan or the Blood Group Diet, but with one word: “paleo”. I figured that since many of these people are often ambassadors for optimum health, they were onto something. Since then, I have done a fair bit of research, asked a lot of questions and more recently tried the paleo lifestyle for myself. Here’s what I found out…


Paleo is short for paleolithic which means of the Stone Age - the time period from about 2.6 million years ago to the beginning of the agricultural revolution about 10,000 years ago. Paleolithic people or cavemen and women were considered hunter gatherers, and the bulk of their diet consisted of animals and wild plants. Existing before the dawn of agriculture, they didn’t eat any processed grains or dairy. They certainly didn’t know about Mars bars, bagels, Innocent Smoothies, Diet Coke, low fat yoghurts or Special K. Imagine you were on a desert island with a club and a stick and not a Tesco Metro in sight, what would you eat? Nuts, berries, green leaves, fish, meat, birds. That is paleo. One of the most commonly used phrases to describe the diet is ‘If it doesn’t fly, swim, walk or isn’t green, then don’t eat it.”  

So first things first: eating the paleo way isn’t new. In fact it’s probably the earliest form of eating known to man, which is why it feels very wrong in a way to call paleo a ‘diet’. I associate the word diet with weight loss, and I’m pretty sure that cavemen and women didn’t have love handles hanging over their loincloths. What paleo is however, is all about simple, fresh, unprocessed, real food, and it is a way of eating that is considered by many experts to work optimally with our genetics to the point where it has the power to act as a medicine.

Decades of research has shown that hunter gatherers typically were free from chronic illnesses and diseases that are epidemic in Western populations.

What can you eat?

Fruits - preferably berries as these are lower in sugar. Nutritionists don’t really advise on bananas due to their high sugar content but I ate them when I needed energy for exercise. I also ate avocado by the bucket load

Vegetables - all green leafy ones, sweet potato, butternut squash, peppers, onions, herbs and salads of all kinds

Lean meats (grass fed if possible) - beef, lamb, pork, chicken, turkey, bacon

Seafood - Any. I particularly like white fish and salmon

Nuts and seeds - almonds, cashews, brazil nuts, walnuts etc Not peanuts as these are a legume

Healthy fats - coconut oil, olive oil on salads, eggs

What can’t you eat?

Dairy  - No cows, sheep or goats’ milk unless it’s raw

Grains  - No bread, pasta, rice, corn or oats. Even quinoa is out. 

Processed food and sugars - no cakes, biscuits, fizzy drinks, cakes, sweets, crisps

Legumes - basically any ‘dried fruit’ from a shell or pod eg peas, beans, or peanuts

Starches - no potatoes

Alcohol - we all know what that is



The reversal of illness and disease

When you learn about primal eating, you soon see that the reason nutritionists and athletes promote paleo is because it’s about eating for optimum health, about nourishing every cell in your body, not depriving it in any way. It represents a way of eating that is at the other end of the spectrum to all the refined foods, trans fats, and sugar which many experts believe to be at the root of degenerative diseases today such as obesity, cancer, Alzheimer’s, depression and heart disease. Paleo expert Robb Wolf writes extensively on his website about the benefits of paleo and shows many fascinating testimonials from people with all sorts of illnesses from MS to migraines, asthma to fibromyalgia, all who have vastly benefited from eating primal, and many of whom have had their illness reversed.

Niall Crowley, paleo eater and co-founder of Eat Evolve, an excellent, high quality primal food delivery service in London (scroll down for a special offer for your first order) says, “We had a woman that came to us who had really terrible eczema, and after one month of eating our paleo food it totally cleared up. It can help with many problems but IBS is one we see being solved time after time.”  Nutritional expert Amelia Freer, an expert and regular on Get the Gloss eats mostly according to paleo principles too and says, “I really went this way when I started finding out about gluten which is in a lot of grains. Once I removed them I felt so much more energetic and it also sorted out my long term digestive problems.” Freer also believes that being paleo can be highly beneficial not only for cardiovascular health but autoimmune conditions such as thyroid, arthritis and type 2 diabetes, all of which she says manifest themselves within the gut.


Weight loss

Having eaten the paleo way for about six weeks (and having eaten a lot and never counted a calorie), it seems almost impossible to put on weight with it. Freer agrees. “You can’t really overindulge if you are eating this way, it’s about eating optimally – eating things our body is designed to digest. We have all been hijacked by the food industry that we need more grains and packets of food, and it’s wrong.”

Niall from Eat Evolve agrees, “You don’t feel like you can overeat on paleo - you don’t want to, and if the weight has to come off, it will, but it’s the other benefits you’ll notice as well - better sleep, better digestion and better skin too.”

Scientifically speaking, what is happening is that when there is an absence of carbs, our body will take stored fat and burn THAT for energy instead - a process called ketogenesis. This means you can eat more on paleo but potentially lose weight.

Stable energy levels

One of the key factors in eating paleo is the removal of grains, which are proven to cause upset in our system. Removing grains and therefore refined carbohydrates from our diet, takes away the extreme glucose highs and crashes that go hand in hand with eating them.

Since Christmas I have been following a paleo eating plan. I haven’t been paleo perfect 100% of the time (on Saturday I ate chocolate brownies with loads of cream and quite a few glasses of wine, for example), but I would say I have followed it 85% of the time.

So how has it been?

I already eat quite a low carbohydrate diet; I rarely eat a sandwich at lunch, or a huge bowl of pasta for dinner. Cutting out grains therefore hasn’t really been the issue for me (although I can imagine if you ate a high carb diet and suddenly switched to paleo it would be much tougher). For me it’s the dairy that’s been hard - I gave up my beloved lattes the first week in January and as a result felt shocking with very low energy; my body and head felt like lead. This may have been the caffeine withdrawal but as Niall of Eat Evolve pointed out you also forget about the sugar that’s in milk (lactose I’m afraid is a sugar).

Combined with the High Intensity exercise story I’m taking part in for GTG, I realised that I probably wasn’t taking in enough good calories. After speaking to my personal trainer Steve Mellor from Freedom2Train (who is also all for eating paleo), I upped my food intake and immediately felt better. One day, after an early morning boxing session, I came home and ate three eggs and three pieces of bacon. Another day I ate an entire packet of green beans with my chicken for dinner. You really do feel as if you can eat as much paleo food as you like.

Lunch has been pretty straightforward as there is a salad bar near work and I would choose chicken or fish with loads of vegetables, leaves, and salad, and for dinner I’d generally eat fish or meat with roasted or stir-fried vegetables(sometimes omelettes). My biggest annoyance however has been buying fresh food that then goes off in the fridge and then having to buy more.

As for snacks, I have mostly munched on fruit such as apples, berries and nuts - sometimes a banana if I was going training (too much sugar in it if you are not exercising). I have also discovered Nakd bars which are wheat and dairy-free and now available at Sainsburys, which give me just the right amount of energy for a training session.


Breakfast issues

It has been the breakfast options that I have found hard to swallow - literally. Really hardcore paleo eaters will eat chicken or salmon for breakfast, probably with a handful of nuts (I literally can barely stomach a cup of tea before 9am let alone fish, so this absolutely wasn’t an option). Coyo yoghurt has really saved my life however - it’s a particularly tasty, creamy, coconut based non-dairy yoghurt that no paleo eater will survive without. I would eat this with a handful of cashews, blueberries and cinnamon which is delicious and very filling.

Breakfast on the go has been hard too and I would often find myself in Pret-a-Manger staring at the shelves trying to find something I could eat (wraps, porridge, those breakfast bowl pots with berry compote are all out of bounds), so I would invariably leave with two boiled eggs (they sell them in a pot) which I would have with a banana and their Naked Nuts much to my colleagues’ horror. I have to admit that eating boiled eggs at your desk is pretty grim - this is when food became totally functional and not much of a pleasure.


Areas I have failed

If you are a die-hard paleo fanatic you shouldn’t drink milk (unless it’s raw or unpasteurised, e.g. straight from the udder), and while I cut out the lattes, I just couldn’t stop having milk in my tea - it’s a habit of a lifetime I am not willing to break. Other areas where I cheated? Dark chocolate - every day at night bar none. Oh and white wine (sometimes a gin and tonic) every Friday and Saturday without fail.

Did I starve?

Absolutely not - if I was hungry I would eat nuts and blueberries, and there is a limit even to how many of those you can eat before you can’t eat any more.


What results have I seen?

If I may say so myself, my skin looks pretty darn good. While I’ve never had acne, I would normally have some sort of spot on the go. As I write this I have none and any bumpiness has totally disappeared - it’s almost as if my skin has been cleaned from the inside out. Somehow the pores even look cleaner.  Niall from Eat Evolve says this is down to the fact that I am not just eating macronutrients - ‘The big blocks of proteins, good fats and carbs’ - but the micronutrients too - ‘The fibre and nutrients that are essential for great skin and cellular repair’.

As for my body, I read a quote from Hollywood paleo eater Jessica Biel that said, “It just leans you down and slims you up and takes that little layer of fat, skin and water-weight right off your body”. I totally understand this. I don’t own any scales but I am fitting into a smaller dress size and definitely feel much leaner and firmer - it’s as if everything has been cleaned out and sucked in.

Another strange side effect is that my senses are heightened dramatically - someone was eating bubblegum in the office the other day and I could smell it a mile away. Herbs and spices have also become a taste sensation. Apparently, according to Amelia Freer, this is not unusual. “I had to change my perfume when I went Paleo, my sense of smell particularly changed!”

Will I carry on?

I will continue to eat as cleanly as I can - I think cutting out all processed food is the way the world will have to go in order to cure disease and prevent obesity. My advice though is to cut back a food group at a time - staart with cutting back on grains first for example, and then dairy as it’s a big deal doing it all at once.

Don’t think however that I will be doing Paleo to the point of extremism - if I go to a friend’s house and they serve up pasta or potatoes I won’t refuse it, and I will continue to go and drink wine at the weekends, eat chocolate brownies and add some parmesan back onto my salads.

I may be eating paleo, but it doesn’t mean I’m perfect.
