We review several different eating approaches in our “Dietitian’s Review” series with the goal of helping people who are looking to evolve their eating style towards better health. It’s important to emphasize that “going on a diet” is very rarely associated with long-term success with weight. We provide these reviews for anyone who wants to improve their health and is looking for an eating approach that will best fit their lifestyle and preferences.
What is it?
Paleo is short for paleolithic. The Paleo diet, or sometimes called the caveman diet, recommends eating only food that was available during the Paleolithic era. In other words, if the caveman ate it… you can too. While it is not necessarily low-carb, some people follow a low-carb version.
What do I eat?
While different authors have slightly different interpretations of what can and can’t be eaten on the Paleo diet, in general, the emphasis is on meats and seafood, fruits, vegetables, and nuts. The Paleo diet usually excludes dairy, grains, sugar, legumes, processed oils, salt, alcohol and coffee. It also excludes very starchy vegetables such as potatoes and butternut squash. It excludes all processed foods.
Is it effective?
There is very little research on the Paleo diet and none carried out over a long period of time as to demonstrate effectiveness. Research is also difficult as there are so many variations of this diet. As with many popular diets that require omitting major food groups, there is concern not only about an individual’s ability to adhere to such strict rules, but also concern that omitting groups of food like dairy could result in low intake of calcium and vitamin D. While some of the principles are sound, such as an emphasis on more whole, unprocessed foods, most experts agree that it is not recommended long term.
What are some pros and cons?
Pros: Emphasis on fruits and veggies, lean meat, seafood and less processed foods is good.
Cons: Not much research pointing to benefits; concern of long-term loss of nutrients (calcium, B vitamins) when major food groups such as grains and dairy are omitted; expensive
