On the diet, you can get frozen and ready-to-eat South Beach Diet meals, along with some meals you make on your own. They also encourage you to buy South Beach Diet–branded snacks. The upside is that they’ll tell you what to eat all day and there’s little cooking involved (great if you hate your kitchen); the downside is that you have to buy your food through them, and the choices can become limiting. Plus, when you’re buying packaged foods, you’re not getting the full nutritional benefit you would from eating whole foods.
My numbers are all excellent. Take a look at my page on the cholesterol myth where I summarise some fabulous books on the subject. Once you go low carb, your triglycerides drop, HDL goes up and LDL becomes the larger fluffy type instead of the small oxidised destructive type. This is an incredible simplification but have a read and see what you think.
For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].
In fact, the health benefits of the paleo diet are unproven. "Our ancestors ate this way and didn't have many of the chronic diseases we do, but that doesn't mean the food they ate is the reason why; drawing that conclusion would be like saying we live three times longer than our Paleolithic ancestors because we eat fast food," says Christopher Ochner, MD, research associate at the New York Obesity Nutrition Research Center at St. Luke's and Roosevelt Hospitals. Still, a handful of small studies have tried to determine if a paleo diet is a healthier diet. One small study published in the journal Diabetologia found that the diet improved blood sugar over 12 weeks compared to a Mediterranean one that allowed grains, low-fat dairy, and oils, but it's hard to say whether researchers would come to the same results in a larger study.
The concept of the glycemic index was developed in 1981 by David Jenkins to account for variances in speed of digestion of different types of carbohydrates. This concept classifies foods according to the rapidity of their effect on blood sugar levels – with fast-digesting simple carbohydrates causing a sharper increase and slower-digesting complex carbohydrates, such as whole grains, a slower one.
Dr. Hall published a meta-analysis of feeding studies last year that suggested that energy expenditure was actually slightly greater on low-fat diets. But Dr. Ludwig pointed out that those studies were very short, with none lasting longer than a month and most lasting a week or less. He said the process of adapting to a low-carb diet can take a month or longer.
Buried in the middle of The Revised Metabolic Oncolytic Regimen for Effecting Lysis in Solid Tumors one can find their diet recommendations for tumor control. It has a paleo diet orientation. Protein is 35%, preferably Omega 3 rich. Carbohydrates (also 35%) are only vegetables and fruit, no beans, bread, potatoes, or any grain. Then dietary and supplemental forms of fat should provide 20-30% of (daily) calories.
Lutein/Zeaxanthin and Macular Health is an article discussing antioxidents and protection against the oxidizing ultraviolet radiation of the sun. The best dietary sources of antioxidants in general, and carotenoids specifically, are fruits and vegetables and the more brightly colored, the better. Lutein and zeaxanthin are yellow pigments found in high concentrations in yellow fruits and vegetables as well as in dark green, leafy vegetables. In particular, spinach, kale and collard greens contain high levels of these two carotenoids.
It seems beyond silly that phase one essentially equates eating a banana with eating a brownie, forbidding both even though they are clearly not the same whatsoever. But at the same time, you are allowed to have artificial sweeteners. And I did begin to crave the sugar-free chocolate syrup and the sugar substitute that I had in my so-necessary endless cups of coffee—and I still do today.
Grass-fed meat is recommended on the paleo diet because it is leaner than meat from grain-fed animals and has more omega-3 fatty acids, the healthy fats that reduce inflammation in the body and protect your heart. A typical American diet is high in saturated and trans fats and lower in healthy poly- and monounsaturated fats, hence the paleo diet's emphasis on grass-fed meats, as well as seafood.
"We found that the type of diet people ate had a major impact on their metabolism. Those on the low-carbohydrate diet burned about 250 calories a day more than those on the high-carbohydrate diet, even though all the groups were the same weight," said Dr. David Ludwig, principal investigator of the study and co-director of the New Balance Foundation Obesity Prevention Center at Boston Children's Hospital.
The South Beach Diet aims to be a lifelong eating plan that you adapt when you reach the maintenance period, which is phase 3. By this point, you have learned how to eat in a healthy way, meaning you can have occasional treats, like a slice of cake, but by using what you learned in phases 1 and 2, you keep yourself from veering too far off the plan.
Carbohydrates are the bodies' main source of energy and the nutrient that impacts blood sugar the most. People with diabetes need to monitor their carbohydrate intake because excess carbohydrates, particularly in the form of white, refined, processed, and sugary foods can elevate blood sugars and triglycerides and result in weight gain. When thinking about carbohydrates, you'll want to think about portions as well as type.
The difference between glycemic index and glycemic load is that glycemic index is a standardized measurement and glycemic load accounts for a real-life portion size. For example, the glycemic index of a bowl of peas is 68 (per 100 grams) but its glycemic load is just 16 (lower the better). If you just referred to the glycemic index, you'd think peas were a bad choice, but in reality, you wouldn't eat 100 grams of peas. With a normal portion size, peas have a healthy glycemic load as well as being an excellent source of protein.
The Military Diet is no different from any other plan that requires you to count calories to lose weight. On your three days "on" the calories are counted for you, but only if you eat the bizarre combination of foods that are suggested. If you substitute any food on your three days “on” you are required to measure your food and count calories. On your four days “off” you are also required to keep a food log and count calories.
To do the new study, Dr. Ludwig and his colleagues collaborated with Framingham State University, about 20 miles outside Boston, where they recruited overweight students, staff members and faculty members. Each participant went through two phases of the study. First, they were put on strict diets that lowered their body weight by about 12 percent, which was designed to stress their metabolisms.

The DASH plan was originally developed to help treat or prevent high blood pressure (hypertension), but it may also reduce the risk of other diseases, including diabetes. It may have the additional benefit of helping you lose weight. People following the DASH plan are encouraged to reduce portion sizes and eat foods rich in blood pressure-lowering nutrients, such as potassium, calcium, and magnesium.
