The Paleo diet, also known as the Caveman diet, the Stone Age diet, and the Palaeolithic diet, is one of thediets that have gained popularity in recent years.
Developed by Dr. Loren Cordain, a professor of health and exercise science at Colorado University, in 2002, who published a book by the name of Paleo Diet in that year. This diet follows the principle of eating what our ancient ancestors ate, which is whole, unprocessed foods.
In this article, we take a thorough look into the Paleo diet. What is it? What are the benefits and risks? And how do you plan it? Let's find out the answers to all of those questions and more.
What is the Paleo Diet?
The Paleo diet relies on what the hunter-gatherers sate millions of years ago, which was whole food. So, the Paleo diet excludes any processed food, whether it's meat or plant-based; it also excludes all frozen and canned food. Anything that has become popular and widespread because of agriculture is excluded from the Paleo diet.
It's noteworthy to say that there are some misconceptions regarding the Paleo diet. What I mean is that the Paleo diet supposedly represents what people ate during the Paleolithic era, but that was a long time ago, and we can't accurately say this is what our ancestors ate during that period. Also, there cannot be one diet for an era because diets vary according to climate and geographical regions.

Here's a list of foods that are Paleo-friendly:
Meat: beef, lamb, rabbit, sheep, etc.

Balances blood glucose levels.
It reduces hunger and make you feel full for a longer duration.
Improves your sleep.

Detoxify your body.
Easy weight loss.

8. Reduces acne.
For better results it's preferable to combine the paleo diet with exercise like running, walking, or resistance training. But, I must emphasizes that you should consulting an expert first.
Drawbacks and risks of the Paleo Diet:
We can't talk about the acclaimed benefits without mentioning the drawbacks and risks that might accompany following a Paleo diet. Those are:
The Paleo diet limits or restricts the intake of grains and legumes, which contain a lot of nutrients.
It also restricts the intake of milk and dairy, which are rich sources of calcium and other minerals.
Legumes are the main source of proteins for vegetarians, which means that this diet is not for them.
The foods that the Paleo diet endorses contain things like fresh meat and fish, which can be somewhat costly.
Lack of long-term research: all the studies that have been done on the Paleo diet are short-term studies. And although those studies show good signs in the short term, there could be health risks in the long term.
6. The Paleo diet is hard to maintain for a long duration, and one thing that matters when you are following a diet is consistency.
Who is This Diet for?
There are some people who might find the Paleo diet particularly attractive because they benefit directly from it. People who benefit from the Paleo diet are:
People who are searching for a fast way to lose weight.
People who have gluten sensitivity or lactose intolerance might like this diet more than other diets.
Diabetic and pre-diabetic patients: since this diet emphasizes low-glycemic foods, it might help diabetic patients stabilize their blood glucose levels.
Those looking to improve their health by avoiding processed food and sugar.
Who Should Avoid This Diet?
While this diet might be beneficial and appealing to certain individuals, some people are advised to avoid it. Those are:
People with Kidney Problems: The high level of proteins in the Paleo diet might pose a strain on the kidneys; this is problematic for those with kidney diseases.
People with Nutritional Deficiencies: The Paleo diet limits the intake of milk, grains, and legumes, which contain a lot of nutrients, so if you are someone who already has deficiencies, this diet is not for you. You can consider taking a dietary supplement to compensate for the loss, but taking nutrients from food and supplements is not the same.
Avoid the Paleo diet if you are pregnant or breastfeeding because you will need all the calcium and vitamin D that you can get.
The Paleo Diet Levels:
The Paleo diet is not so strict as to not be modified at all. Like any other diet, the Paleo diet can be a cornerstone on which you build your diet the way that works better for you, but by all means, it's not something that you need to follow strictly as it is. Here are the levels of the Paleo diet:
80/20 Paleo: this level is for beginners. As the ratio states, 80 percent of the time you can be flexible and eat as you like, and 20% of the time you will eat only Paleo diet food.
Modified Paleo: this is more strict; you increase the percentage of Paleo diet foods, but you still allow yourself some flexibility.
Strict Paleo: Here, you limit what you eat to Paleo food only. Anything else is completely restricted.

The Paleo diet can result in significant weight loss in the beginning that's most likely to be water loss.
There are no long-term studies on the effects of the Paleo diet, and hence it's difficult to assess its safety in the long term.
Remember, if a diet works for someone, that doesn't mean it will work for you. Before you start any diet, you need to consult your doctor because there might be diets out there that might affect your health negatively. Also, before starting any diet, it's better to talk to a dietitian; they know better about this and can help you decide which diet works best for you, as well as help you plan your meals and give you expert advice.
