In 1863, William Banting, a formerly obese English undertaker and coffin maker, published "Letter on Corpulence Addressed to the Public", in which he described a diet for weight control giving up bread, butter, milk, sugar, beer, and potatoes. His booklet was widely read, so much so that some people used the term "Banting" for the activity usually called "dieting".
The China Study is frequently cited when criticizing the Paleo Diet – focusing on a vegetarian diet and consuming rice is healthier than the Paleo Diet. I respectfully disagree with that nutritional philosophy and strongly disagree with the conclusions drawn from that book , and will leave you to make your own conclusions based on your own self-experimentation.
Your body uses carbohydrates as its main fuel source. Complex carbohydrates (starches) are broken down into simple sugars during digestion. They're then absorbed into your bloodstream, where they're known as blood sugar (glucose). In general, natural complex carbohydrates are digested more slowly and they have less effect on blood sugar. Natural complex carbohydrates provide bulk and serve other body functions beyond fuel.
If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
But experts like Dr. Ludwig argue that the obesity epidemic is driven by refined carbohydrates such as sugar, juices, bagels, white bread, pasta and heavily processed cereals. These foods tend to spike blood sugar and insulin, a hormone that promotes fat storage, and they can increase appetite. Dr. Ludwig and his colleague Dr. Cara Ebbeling have published studies suggesting that diets with different ratios of carbs and fat but identical amounts of calories have very different effects on hormones, hunger and metabolism. He has also written a best-selling book on lower-carb diets.
One study, published in the journal Nutrition & Metabolism, found a group of 28 people with type 2 diabetes overall lost about 6 percent of their body weight and lowered their blood glucose levels when they followed a keto diet for 16 weeks. The authors recommended individuals on this diet who have diabetes be under close medical supervision, and noted more research is needed on the diet’s long-term effects because the study was small and short term.
Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health by Gary Taubes expounds on his 2002 article in the NY Times (What if It's All Been a Big Fat Lie?) and then in Science Magazine (see below). He shows how public health data has been misinterpreted to mark dietary fat and cholesterol as the primary causes of coronary heart disease. Deeper examination, he says, shows that heart disease and other diseases of civilization appear to result from increased consumption of refined carbohydrates: sugar, white flour and white rice. Or in other words, without using the word Paleolithic, he justifies the paleo diet. Here is an excellent chapter by chapter summary of the book [archive.org].
One of the most straightforward ways to lose weight is to eat a bit less. Remembering that American portion sizes have ballooned as much as 138% in the past 50 years, cut down on your daily dose of food just a little, and whatever meal plan you choose can be a winner. A cut of chicken should fit in an imaginary deck of cards, and your serving of cheese should be about as big as three stacked dice.
Upton explains that keto-approved meals contain fish (salmon, oysters, scallops), meat and poultry (pork, lamb, steak, and yes, bacon!), eggs, nuts, non-starchy vegetables (spinach, broccoli, cauliflower, tomatoes), fats and oils (butter, mayo, avocado oil, ghee), and high-fat dairy (full-fat yogurt, heavy cream, cream cheese, hard and soft cheese). Berries and artificial sweeteners can be eaten sparingly.
But a large new study published on Wednesday in the journal BMJ challenges the conventional wisdom. It found that overweight adults who cut carbohydrates from their diets and replaced them with fat sharply increased their metabolisms. After five months on the diet, their bodies burned roughly 250 calories more per day than people who ate a high-carb, low-fat diet, suggesting that restricting carb intake could help people maintain their weight loss more easily.
The Lazy Paleo Enthusiast's Cookbook: A Collection of Practical Recipes and Advice on How to Eat Healthy, Tasty Food While Spending as Little Time in the Kitchen as Possible by Sean Robertson. The author is a recovering vegan and in the first half of the book recounts his dietary experiences using some paleo foods to restore his health. You learn that the author's main strategy is to make food in large batches which can be reheated to provide dinners for several days running. The second half of the book contains 28 recipes. Some borderline or nonpaleo ingredients do appear, but most of the recipes are more paleo than not. Published November 15, 2011.
Fat and Cholesterol are Good for You by Uffe Ravnskov is a new book which includes updated and simplified sections from his previous one (The Cholesterol Myths). Ravnskov also presents his own idea about the cause of heart disease, an idea that explains all the findings that do not fit with the present view. It is a powerful book. Also see his web site. The Amazon.com reviews average to 5 stars. Published January 26, 2009.
Combining higher protein intake and fresh vegetables leads to another major benefit: blood sugar stabilization. Between 35 and 45 percent of the average Paleo diet is comprised of non-starchy fresh fruits and vegetables that won’t spike blood sugar levels, making it an optimal diet for diabetes prevention. This is because nearly all of these foods have low glycemic indices that are slowly digested and absorbed by the body.
