In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.


Cordain explains that high intake of fruits and vegetables is one of best ways to reduce chances of cancer and heart disease. He notes that protein has twice the calorie burning effect of fat and carbs and is more satiating than both. He explains that starch, fats, sugars, and salts together cause us to keep eating. So if we limit our diet to fruits and vegetables and/or meat, we’ll stop eating when we’re full. And if you stop eating when you’re full, you’ll lose weight and won’t get fat. And as you lose weight, your cholesterol will improve (regardless of what you eat). This all makes sense and can’t really be disputed. If you want to lose weight, the Paleo diet will get you there and probably quickly. But Cordain’s hypothesis applied to long-term health falls short.
That being said, as a person with Type 2 diabetes, I found Nutrisystem had too many carbs – and I ordered the diabetic version. Then again, not every diabetic is as sensitive to carbs as I am. SBD also used whole grain options when using grains, which is better for diabetics. I can’t say for certain that Nutrisystem didn’t, but it didn’t taste and look like they did and as I say, even the diabetes version caused more problems with my glucose levels.
Similarly, the small “EcoAtkins” weight loss trial compared a low-fat, high-carbohydrate vegetarian diet to a low-carbohydrate vegan diet that was high in vegetable protein and fat. While weight loss was similar on the two diets, study subjects who followed the low-carbohydrate “EcoAtkins” diet saw improvements in blood lipids and blood pressure. (36)
Get rid of the temptation – if you’re gonna go at this thing with a full head of steam, remove all the junk food from your house.  It’s going to take a few weeks for your body to adjust to burning fat instead of glucose, and you might want to eat poorly here and there. If there’s no food in your house to tempt you, it will be much easier to stay on target.
Nuts are another Mediterranean diet staple. Grabbing a handful, whether that's almonds, cashews, or pistachios, can make for a satisfying, on-the-go snack. One study in Nutrition Journal found that if people replaced their standard snack (cookies, chips, crackers, snack mix, cereal bars) with almonds, their diets would be lower in empty calories, added sugar, and sodium. Plus, nuts contain more fiber and minerals, such as potassium, than processed snack foods.
In the long term, you have to be sure you’re getting calcium and other nutrients you’re missing by not having dairy products and certain grains. Some paleo-approved foods, such as salmon and spinach, contain calcium, so you have to be sure you’re including them in your diet. It would be a good idea to check with a registered dietitian, too, to make sure you’re meeting your calcium and other nutrient needs.
Sheila and Joel decide they need to kill the zombified Gary. Gary agrees, but asks them to bring the deed to his Michigan lake house to his niece Kayla. Sheila and Joel decide to honor Gary's last request. Eric finds a corpse in Ramona's bathtub and calls Abby, who sets out to rescue him. Sheila and Joel bring the deed to Kayla, but she still needs her car, which is with her ex-boyfriend, Boone. Sheila volunteers herself and Joel to retrieve the car. Abby bursts into Ramona's apartment but realizes that Eric and Ramona actually had sex. Ramona discloses that she is also deteriorating and Eric offers to help her. At Boone's house, Sheila and Joel discover that he is the "young, single Hitler" type that Sheila can eat guilt-free. While debating whether they should kill again impulsively, Boone's friend AJ shows up and offers them a raffle book for the Nazi softball team. Sheila buys one as a future kill reference. After Eric gives Ramona the serum to halt her deterioration, she admits that she was just using him for his ties to Abby's mother and they break up. Abby discovers Gary in the basement.
Refined carbs lack nutrients and can wreak havoc on your blood sugar. Whole grains are best; have four small daily portions of whole-wheat bread, or try a pasta made from quinoa. And always eat grains with healthy fats and protein. Incorporate sprouted or fermented grains (hello, sourdough!) for easier digestion and better nutrient absorption. Or look for creative ways to swap out grains, such as using spaghetti squash in place of noodles.
The Paleo diet, also referred to as the caveman or Stone-Age diet, includes lean meats, fish, fruits, vegetables, nuts, and seeds. Proponents of the diet emphasize choosing low-glycemic fruits and vegetables. There is debate about several aspects of the Paleo diet: what foods actually existed at the time, the variation in diets depending on region (e.g., tropical vs. Arctic), how modern-day fruits and vegetables bear little resemblance to prehistoric wild versions, and disagreement among Paleo diet enthusiasts on what is included/excluded from the diet. Because of these differences, there is not one “true” Paleo diet.
Once blood glucose levels have remained consistently low for a period of time (typically two to three days) the body adapts and the liver begins to produce ketones from free fatty acids. Ketones can be metabolized by many cells in the body including those cells that cannot directly metabolize fat. Once the body's production of ketones reaches a certain level the body is in nutritional ketosis. When the body is in nutritional ketosis fat becomes the primary energy source, and the body metabolizes stored fat and dietary fat.
Spinach is a great source of iron, which is a key component in red blood cells that fuel our muscles with oxygen for energy. But researchers in Sweden identified another way in which these greens might keep you charged: Compounds found in spinach actually increase the efficiency of our mitochondria, the energy-producing factories inside our cells. That means eating a cup of cooked spinach a day may give you more lasting power on the elliptical machine (or in your daily sprint to catch the bus).

A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows. Some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy.


At the 20-week point, the effects were quite remarkable: The fewer carbs a person ate, the more calories they burned — and, the logic goes, the easier it’d be to keep their weight off. So people on the low-carb diet burned more than 200 extra calories each day, while people on the moderate-carb diet burned about an extra 100 calories per day, and people on the high-carb diet didn’t burn any extra calories.


The first stage of the diet aims for rapid weight loss (13 lbs in two weeks). According to the UK's National Health Service (NHS), the severity of the first stage of the diet may result in the loss of some vitamins, minerals and fiber. The NHS reports that dietary restrictions during stage one may cause side effects including "bad breath, a dry mouth, tiredness, dizziness, insomnia, nausea and constipation."[8] Such symptoms would be rectified once the less extreme phases of the diet then began.[8]
