Arctic cultures, such as the Inuit, were found to lead physically demanding lives consuming a diet of about 15–20% of their calories from carbohydrates, largely in the form of glycogen from the raw meat they consumed. However, studies also indicate that while low-carb diets will not reduce endurance performance after adapting, they will probably deteriorate anaerobic performance such as strength-training or sprint-running because these processes rely on glycogen for fuel.
The Paleo Diet Cookbook: More than 150 recipes for Paleo Breakfasts, Lunches, Dinners, Snacks, and Beverages by Loren Cordain. Also contains two weeks of meal plans and shopping and pantry tips. Helps you lose weight and boost your health and energy by focusing on lean protein and non-starchy vegetables and fruits. Note that this is a very low-fat book and is being marketed as such. Published December 7, 2010.
The main scientific model in that latter camp is the ”carbohydrate-insulin hypothesis,” which Taubes, Harvard professor David Ludwig (an author on the new paper), University of California San Francisco’s Robert Lustig, and others have extensively promoted. It suggests that a diet heavy in carbohydrates (especially refined grains and sugars) leads to weight gain because of a specific mechanism: Carbs drive up insulin in the body, causing the body to hold on to fat and suppress calorie burn.
There are 3 phases to the South Beach Diet. "The South Beach Diet provides the right nutrients to keep you feeling satisfied, while still losing weight. Phase 1 is about breaking the sugar habit. In phase 2, good carbs like fruits and whole grains are added and then phase 3 is really about how you’ll eat to maintain a healthy weight," says Dr. Agatston.
There is some evidence that the Mediterranean diet lowers the risk of heart disease and early death. Olive oil may be the main health-promoting component of the diet. There is preliminary evidence that regular consumption of olive oil may lower all-cause mortality and the risk of cancer, cardiovascular disease, neurodegeneration, and several chronic diseases.
The people who live along the Mediterranean—the Spanish, Italian, French, Greek, and others—are not known to shy away from wine, but that doesn't mean you should pour it at your leisure. Dietitians and experts who developed the Mediterranean diet for the New England Journal of Medicine study advised women to stick to a three-ounce serving and men, a five-ounce serving, per day. When you do sip, try to do so with a meal—even better if that meal is shared with loved ones. If you're a teetotaler, you shouldn't start to drink just for this diet.
Gabbi Berkow, MA, RD, CDN, CPT, is a Paleo advocate. She maintains the whole, unprocessed foods the diet recommends are low in calories, are high in nutrients, provide the fuel the body needs, and are the kinds of foods humans have evolved to easily digest. However, she doesn't agree with the blanket recommendations that everyone needs to eliminate dairy, grains (in particular, those containing gluten), and legumes, unless they have a medical condition that warrants it (eg, celiac disease or dairy allergy). In addition, Berkow says, "Dairy in particular is a good source of protein, calcium, and vitamin D, so cutting out dairy can make it harder to get enough of these nutrients."
Because this is an eating pattern – not a structured diet – you're on your own to figure out how many calories you should eat to lose or maintain your weight, what you'll do to stay active and how you'll shape your Mediterranean menu. The Mediterranean diet pyramid should help get you started. The pyramid emphasizes eating fruits, veggies, whole grains, beans, nuts, legumes, olive oil, and flavorful herbs and spices; fish and seafood at least a couple of times a week; and poultry, eggs, cheese and yogurt in moderation, while saving sweets and red meat for special occasions. Top it off with a splash of red wine (if you want), remember to stay physically active and you're set.
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.
The new research is unlikely to end the decades-long debate over the best diet for weight loss. But it provides strong new evidence that all calories are not metabolically alike to the body. And it suggests that the popular advice on weight loss promoted by health authorities — count calories, reduce portion sizes and lower your fat intake — might be outdated.
No clear proof exists that taking dietary supplements such as vitamins, minerals, herbs, or spices can help manage diabetes.1 You may need supplements if you cannot get enough vitamins and minerals from foods. Talk with your health care provider before you take any dietary supplement since some can cause side effects or affect how your medicines work.2
