It has been repeatedly found that in the long-term, all diets with the same calorific value perform the same for weight loss, except for the one differentiating factor of how well people can faithfully follow the dietary programme. A study comparing groups taking low-fat, low-carbohydrate and Mediterranean diets found at six months the low-carbohydrate diet still had most people adhering to it, but thereafter the situation reversed: at two years the low-carbohydrate group had the highest incidence of lapses and dropouts. This may be due to the comparatively limited food choice of low-carbohydrate diets.
Nutrition & Physical Degeneration by Dr. Weston Price's book puts to rest a lot of myths about diet, dental, physical, and emotional health, and presents the strongest case for a super-nutritious Native (or Paleo) Diet. His book outlines the conditions/causes for exceptional health. A classic that was first published in 1938. The Soil and Health Library has a Book Review by Steve Solomon. If you don't buy the book at least read the review. N.B. If you live in one of the countries where this book is now in the public domain, you can read it online. But not if you live in a country where it is still under copyright protection.
The Hiwi gather and hunt a diverse group of plants and animals from the savannas, forests, rivers and swamps. Their main sources of meat are capybara, collared peccary, deer, anteater, armadillo, and feral cattle, numerous species of fish, and at least some turtle species. Less commonly consumed animals include iguanas and savanna lizards, wild rabbits, and many birds. Not exactly the kind of meat Paleo dieters and others in urban areas can easily obtain.
“A healthy diet should be a sustainable eating plan that provides adequate nutrition to support optimal health,” Taylor says. “For many people with diabetes, a low-carb diet is a temporary tool that can be used to support short-term weight loss and improved blood sugar control. However, I typically don't recommend sticking with a low-carb diet permanently, as many micronutrient deficiencies can result from an unbalanced eating plan. I like to think of low-carb diets as a possible ‘stepping stone,’ not a ‘forever diet.’”
“Low-carb diets that replace carbohydrates with protein or fat are gaining widespread popularity as a health and weight loss strategy,” Sara Seidelmann said in a statement. “However, our data suggests that animal-based low carbohydrate diets, which are prevalent in North America and Europe, might be associated with shorter overall life span and should be discouraged.”
Meet Grok. According to his online profile, he is a tall, lean, ripped and agile 30-year-old. By every measure, Grok is in superb health: low blood pressure; no inflammation; ideal levels of insulin, glucose, cholesterol and triglycerides. He and his family eat really healthy, too. They gather wild seeds, grasses, and nuts; seasonal vegetables; roots and berries. They hunt and fish their own meat. Between foraging, building sturdy shelters from natural materials, collecting firewood and fending off dangerous predators far larger than himself, Grok's life is strenuous, perilous and physically demanding. Yet, somehow, he is a stress-free dude who always manages to get enough sleep and finds the time to enjoy moments of tranquility beside gurgling creeks. He is perfectly suited to his environment in every way. He is totally Zen.
Update: So I just finished Day 23 of my Whole30 Journey and I feel good, aside from the fact that I caught a cold. Weighing myself today, I discovered that I lost 19.5 pounds so far! I measured myself and immediately noted that I lost 19 inches over all (I measure my chest, both arms, both legs, waist, and hips). I think when I am done with my first round, I'll take a day off then start a second round. I just feel that great overall.
Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.
Catching Fire: How Cooking Made Us Human by Richard Wrangham. This book argues that the ease of digestion and the added nutritional value available in cooked food was the key behind the explosion of human intelligence. (Cooking gelatinizes starch, denatures protein, and softens all foods, permitting more complete digestion and energy extraction. As a result, the food processing apparatus shrinks, freeing energy to support a larger brain.) He then suggests that cooking led to what eventually became marriage and the sexual division of labor. The two most helpful reviews at Amazon get into great detail. The reviews average to 4+ stars.
To make the curry sauce, melt the cooking fat in a saucepan over medium heat and swirl to coat the bottom of the pan. When the fat is hot, add the onion and cook, stirring, until translucent, 2 to 3 minutes. Add the garlic and stir until it becomes aromatic, about 30 seconds. Add the curry powder and stir for 15 to 20 seconds, taking care that the garlic and curry powder don’t burn. Add the tomatoes and simmer until thickened, about 5 minutes. Transfer the contents of the pan to a food processor or blender and puree until smooth. Pour into a mixing bowl and let cool. Mix in the coconut cream, salt, and pepper.
You’ll lose weight because any time you restrict entire food groups, your calorie intake tends to be lower, Sandon says. And whenever you burn more calories than you consume, you'll have weight loss, she says. (2) The focus on lean protein, fruits, and vegetables over calorie- and sodium-rich processed foods can also contribute to weight loss, though she also points out that the paleo diet wasn’t created to be a weight loss diet.
