First, the term paleo is short for paleolithic. Paleolithic refers to a period of human history distinguished by hunters and gatherers and the development of stone tools during the Stone Age, lasting from roughly 2.6 million years ago to 12,000 years ago. In the 1970s, gastroenterologist Walter Voegtlin spread the idea of the Paleo diet and believed our ancestors could teach us how to eat.
The purpose of the Paleo diet is to imitate the lifestyles of our ancestors by eating the whole foods presumed to have been eaten by early humans in order to escape the negative health effects of the Western diet (standard American diet). This diet is not just about avoiding processed foods and the premise is to avoid any foods that came along with the agricultural revolution when humans transitioned from hunters and gatherers to farmers. The theory supporting the Paleo diet is that agriculture developed too fast for humans to naturally adapt, so the foods that came along with it are not optimal for humans to digest.

First, the Mediterranean countries are those that surround the Mediterranean sea, including twenty sovereign countries in Southern Europe, the Levant, and North Africa. American scientist Ancel Keys discovered the correlation between diet and cardiovascular disease for the first time in the 1950s. With cardiovascular disease being the number one cause of death in the world and an increasing number of deaths reported in the US, the Mediterranean diet gained popularity in the US during the 1960s.
There is no clear cut Mediterranean diet since everyone living around the Mediterranean sea ate differently. The key parts of the Mediterranean diet are smaller portions, high amounts of plant foods, and low amounts of animal foods. Additionally, it is important to know that people living around the Mediterranean Sea were exercising on a daily basis and sharing their meals with family and friends. The reality is that the “Mediterranean diet” is actually a lifestyle for the Mediterranean people and it has proven to lead to significant health benefits.
What You CAN And CANNOT Eat
There is no food groups you CANNOT eat and the Mediterranean diet is more concerned about how often you consume them. Also, you can consume processed foods like pizza, pasta, and bread in moderation; they are consumed frequently in Southern Europe, but they are prepared with healthier ingredients and in much smaller portions compared to the US. Since there is no one Mediterranean diet, you can modify it to find what works best for your health. Below is an accurate representation of what Mediterranean people ate based on several sources.
Eat legumes, nuts, seeds, whole grains, vegetables, fruit, dairy, and healthy oils (mainly olive) DAILY. Eat eggs, fish, and poultry, and drink some wine WEEKLY. Eat red meat MONTHLY.
First, The term vegan pertains to practicing abstinence from the use of animals or their by- products, particularly related to consumption(diet). Foods that contain any meat or meat derived products such as honey, milk, eggs, etc are prohibited when practicing veganism. The diet originated anywhere from 3300-1300 BC in northern and western ancient India. Veganism was based on a spiritual concept of purity and later as time progressed evolved into a cure for various diseases and an overall way of life.
Veganism and has been practiced throughout history and the diet has grown progressively over the years to be more than just a trend. The health benefits of the diet are undeniable, with scientific studies proving the diets overall enhancements on health and abilities in aiding with the prevention of various diseases and illnesses. The misconceptions with veganism is that the diet provides an insufficient supply of protein. Studies have shown that with a balanced vegan diet, protein supply is more than adequate as the diet contains various sources of protein including nuts, legumes, soy, etc.

The keto diet is an extreme low-carbohydrate diet that aims to promote the metabolism of fats into ketone bodies (rather than carbohydrates into glucose) to provide the body's main source of energy. This diet became mainstream in the early 1900’s as a cure for epilepsy. Over the years and as medicine enhanced the diet has been altered and for short terms abandoned. Recently it has been adopted throughout most of society once again and seems to be prevalent across all age groups.
The diet is called Keto because it mimics the effects of fasting an ancient diet that has proven health benefits for both body and overall brain function. The keto diet puts the body in a state of ketosis, using fatty acids and ketone bodies as the primary source of energy rather than glucose . In order to achieve ketosis, consumption of carbohydrates need to be minimal while consumption of fats and proteins should be higher in order to shift. While there have been many cases where the Keto diet has shown a dramatic loss in weight(fat), no long term studies on the effects of health have been shown.
What You Can and CANNOT Eat:
There are no specific restrictions as far as consuming specific foods. The diet requires low Glycogen levels so the consumption of carbohydrates needs to be minimal, about 50 grams a day for the average person.
Everyone has different genetics and digestive tracts, so no diet works for anyone. Everybody must become their own scientist and experiment by seeing which foods digest well with them and lead to their own optimal health.
