There are many nutritionists who criticize Paleo diet because of the misinterpretation surrounding its core. According to, Paleo is not a diet, but an ancestral approach to our food routine that takes us back to the Paleolithic era when people didn’t use food processors, sugar, grains or dairy products to maintain their healthy, fit bodies.

Despite the misinterpretation, in 2013, Paleo was the most popular diet of the year. So people seem to love it anyway. And who can blame them when there are so many benefits for doing it. However, to clear the fog for those who are still skeptical, we have gathered a few studies to prove that Paleo diet actually works.

Weight loss results

One of the Paleo diet benefits listed on refers to weight loss. Let’s see what the scientific world has to say about this. In a study published online in 2014 in PMC US National Library of Medicine National Institutes of Health, eight researchers have studied the long-term effects of Paleolithic Diet on obese postmenopausal women.

Compared to other studies, this one is unique in the sense that it was developed over a two-year period so they could see the long-term effects of the Paleo diet. The study included 70 obese women with the average age of 60 and the goal was to compare the effects of a Paleo diet to the effects of a normal low-fat diet.

The Paleo diet included its most popular ingredients like approved meat, fish, eggs, vegetables, nuts and berries. Even though the women in the Paleo diet group didn’t follow the instructions very thoroughly, the conclusion of the study was pretty gratifying.

Overall, Paleo diet has proved to have greater benefits than the standard low-fat diet in regards to fat mass, abdominal obesity and triglyceride levels.

Metabolic system

Another research paper published in 2014 studied the effects of Paleo diet on the metabolic system. Specifically, the authors looked to see if the diet altered in any way the characteristics of the metabolic syndrome.

They also obtained more information on the feasibility and design of a new dietary research program based on the Paleo diet. The study included 34 subjects, with at least two characteristics of the metabolic syndrome, who were randomized in a two-week Paleo diet or a reference diet.

After 32 subjects completed the trial, the study summed up that engaging in a Paleo diet, even for two weeks only, can significantly improve several cardiovascular risk factors in patients with metabolic syndrome compared with the other healthy reference diets used in the study.

Type 2 diabetes

An older study published in 2009 looked at the beneficial effects of the Paleo diet on cardiovascular risk factors in type 2 diabetes patients. Their goal was to measure whether the Paleo diet had any positive effects compared to a normal diabetes diet recommended for heart diseases to patients with type 2 diabetes without taking insulin.

The study included 13 patients who were instructed on the Paleo diet consisting of lean meat, fish, fruits, vegetables, root vegetables, eggs and nuts during three consecutive months. On the other hand, the diabetes diet was outlined according to the available dietary guidelines.

After three months, the authors discovered that the Paleo diet had a positive impact on the subjects who proved to have improved heart function and better glycemic control compared to those who followed the standard diabetes diet.

Lower cholesterol

This study is fairly new and was published in 2015. Its goal was to measure the effects of the Paleo diet compared to a “heart healthy diet” in regards to cholesterol profiles. Twenty subjects aged 42 to 60 with high cholesterol were selected. No patient took any medication at the time of the study, and when the study began, they were given a four-month “heart healthy diet”.

After the first four months, they started on the Paleo diet for an equal period of time. The researchers compared the results and arrived at the conclusion that Paleo diet significantly improved the levels of cholesterol for the enrolled patients compared to the “heart healthy diet”.

They also stressed the fact that Paleo diet has a promising potential for better nutritional management concerning people with abnormal levels of lipids in their bodies.

Grains and dairy products

Theoretically, the next lines are not directly related to Paleo diet studies but there is a strong connection. You probably have heard about gluten, an ingredient found in rye and wheat, and you probably have also noticed the “gluten free” labels on various items at the supermarket.

They are not an accident at all because it has been discovered that gluten actually fights against consumption thanks to its lectin composition. So it is not designed for our body.

As far as dairy products are concerned, think about all those people who are lactose intolerant. That’s not accidental either. The human organism is not built to absorb large quantities of dairy or grains, and that’s why the philosophy of Paleo diet is successful at offering great results regarding our bodies.


Now you have the proof that Paleo diet does work and more importantly that it has extremely important and beneficial repercussions for our bodies. The studies described above have a strong scientific background, but if you take a look at, you will find a list with other benefits that don’t only relate to medical conditions.

In fact, when you put your mind to it, giving up everything that’s toxic in food, it’s clear that your body will show improvements on every level whether it’s muscle strength or a less stressful mind due to getting better sleep.

All in all, even if you feel good about your body, you should still try living Paleo style for at least 30 days and see whether there are any improvements or not. One thing is sure, you will definitely have fun discovering amazing recipes based on very few, but healthy ingredients.
