I have been hearing about the paleo diet and wanted to check into it to learn more. What is the Paleo Diet?
The originator of this diet, Dr. Loren Cordain, is on the faculty Colorado State University in the dept. of Health and Exercise Science. He has been at work for 20 years looking at the effects of diet on human health and specifically working to examine links between modern day eating habits and disease. He is the author of the three books, The Paleo Diet, The Paleo Diet for Athletes, and The Dietary Cure for Acne.
Paleo Diet Basics:
The main premise of the Paleo Diet is to mimics the kinds of food that people ate before the Agricultural Revolution. Specifically , this consists of fresh fruits, vegetables, lean meats, and seafood. These healthy foods tend to be high in soluble fiber, antioxidant vitamins, phytochemicals, omega-3 and monounsaturated fats, and low-glycemic carbohydrates. These foods also promote good health by not having the refined sugars and grains, saturated and trans fats, salt, high-glycemic carbohydrates, and processed foods that frequently cause weight gain, cardiovascular disease, diabetes, and many additional health problems that people suffer with today. In essence The Paleo Diet replaces dairy and grain products with nutrient rich fresh fruits and vegetables.
Weight Loss Diets
Let’s look at a couple of models for weight loss that are popular and have molded the way we think about losing weight.
Low Fat/High Carb
Burning more calories than we take in is a standard formula for weight loss as we all seem to know, but conventionally it has been assumed that the best way to accomplish this is to eat a plant-dominated, low-fat, and high-carbohydrate diet. Well, that calorie part of this is true, a net caloric decrease must take place in order to lose weigh. But when Cordain looked at the experience that most people have when they are on a low-calorie, high-carbohydrate diet he found that mostly it is unpleasant and unsatisfying. People on this type of diet experience being hungry all the time, and for most people, any weight they do lose they regain right away or within a few months of the initial loss.
Low Carb/ High Fat
On the other hand, diets that promote low-carbohydrate, high-fat diets also offer us a way to lose weight, but only for the short term, and in the long run they promote an unhealthy diet because of the reliance on fats (butter, fatty meats, bacon, cheeses, etc.) at the expense of healthful and nutrient rich fruits and vegetables.
In the end both of these ways of dieting have proven to be ineffective and unsatisfying, to say nothing of being unhealthy. Cordain’s premise is that when the agricultural revolution occurred about 10,000 years ago, a dramatic change took place in human nutrition. Now in our modern diet, cereal grains, legumes, dairy, vegetable oils, salt, alcohol, and refined sugars comprise 72% of the nutrition in western cultures. These foods contain harmful substances that are associated with many of the “diseases of civilization”, including diabetes, celiac disease and other autoimmune diseases, obesity, hypertension, certain cancers, acne, polycistic ovary syndrome, myopia, dyslipidemia, cardiovascular disease, and more.
The Paleo Diet offers an alternative. This is a diet that matches what our hunter-gatherer ancestors ate. They ate a high-protein, high-fruit and veggie diet with moderate amounts of fat, that was bountiful in healthful omega-3 and monounsaturated fats. Why protein is good for you: It has two to three times the thermic effect of either fat or carbohydrate, meaning that it gets your metabolism going, which speeds up weight loss. Also protein fills you up more than either fats or carbohydrates, so it has the effect of more easily controlling your appetite. Lastly, according to Cordain, three recent clinical trials have concluded that high-protein diets are more effective than low-fat, high-carbohydrate diets in promoting weight loss.
Basically the Paleo diet is about eating lean meats, seafood, vegetables, fruits, and nuts and not eating grains and sugars.
