Atkins Diet Tougher on Heart After Weight Loss “In the "maintenance" phase that occurs after initial weight loss, the popular Ornish and South Beach diets seem to be easier on the heart than the high-fat, low-carbohydrate Atkins regimen, a new study finds. … "The outcome does show an indication for concern about the impact of a diet like the Atkins diet that relies on a large amount of saturated fat and the effect on heart health," she said.”
"Eco-Atkins" diet lowers heart risks: study “The traditional Atkins low-carb diet, in which people cut out carbohydrates and eat more meat, has been shown to help lower blood fats known as triglycerides and raise high-density lipoprotein cholesterol or HDL, the "good" cholesterol, but it also tends to raise bad cholesterol levels. Jenkins and colleagues looked to see if a vegetarian version of the Atkins diet that was high in vegetable proteins from gluten, soy, nuts, fruits, vegetables, cereals and vegetable oils might have more heart benefits. … After a month, people in both groups lost about four kilograms, or 8.8 pounds. But people on the low-carb, plant protein diet had lower LDL cholesterol and healthier blood pressure compared with those on the high-carb diet. Jenkins said the study suggests a plant-based low-carb diet may be an effective option for people with high cholesterol who want to lose weight.”
Fewer Calories Equals Less Weight, Regardless of Carb, Fat, or Protein Content
Four Low-Calorie Diets Yield the Same Mediocre Results
Just Eat Less! Heart-healthy, Low-cal Diets Promote Weight Loss Regardless Of Fat, Protein And Carb Content “"These results show that, as long as people follow a heart-healthy, reduced-calorie diet, there is more than one nutritional approach to achieving and maintaining a healthy weight," said Elizabeth G. Nabel, M.D., director, NHLBI. "This provides people who need to lose weight with the flexibility to choose an approach that they're most likely to sustain—one that is most suited to their personal preferences and health needs."”
Mediterranean Diet Reduces Long-term Risk Of Subsequent Weight Gain And Obesity Among Adults “In conclusion, the researchers found that increased fruit and vegetable intake was associated with significantly lower risk of a medium WG (3,41 kg) over 10 years among adults of a Spanish Mediterranean population. Dietary strategies to increase fruit and vegetable intake to prevent and control overweight and obesity should be promoted more vigorously. The researchers concluded that dietary patterns associated with a high intake of fruits and vegetables in Mediterranean populations may reduce long-term risk of subsequent WG and obesity among adults.”
Moderately Reduced Carbohydrate Diet Keeps People Feeling Full Longer “When carbs are eaten and digested, they change into sugar. Before and after the meal, the researchers measured the subjects' levels of insulin and circulating glucose (nonfasting blood sugar) and asked them to rate their hunger or fullness. They evaluated insulin response to a meal and blood sugar levels, because lower insulin and stable blood sugar levels may contribute to increased feelings of fullness, Gower explained. Their research showed that, even in the absence of weight loss, a modest reduction in dietary carbohydrates was sufficient to lower insulin and stabilize blood sugar after a meal. Ratings of fullness were higher in the group on the moderate-carb diet before eating breakfast and stayed higher for a longer time after the meal, compared with those eating the standard diet. "Over the long run a sustained modest reduction in carbohydrate intake may help to reduce energy consumption and facilitate weight loss," Gower said.”
Obese Patients' Reaction to Diet Can Be Predicted, Study Finds
Successful Weight Loss With Dieting Is Linked To Vitamin D Levels “Additionally, higher baseline vitamin D levels (both the precursor and active forms) predicted greater loss of abdominal fat. "Our results suggest the possibility that the addition of vitamin D to a reduced-calorie diet will lead to better weight loss," Sibley said. She cautioned, however, that more research is needed. "Our findings," she said, "need to be followed up by the right kind of controlled clinical trial to determine if there is a role for vitamin D supplementation in helping people lose weight when they attempt to cut back on what they eat." “

What Is The Atkins Diet? What Are The Benefits Of The Atkins Diet? “The thrust of the Atkins Nutritional Approach is to significantly reduce one's carbohydrate (carbs) intake. The craze for low carbs comes mainly from the popularity of the Atkins' books. The Atkins diet is a four-phase eating program, combined with vitamin and mineral supplements, as well as regular exercise. Dr. Atkins said there are crucial unrecognized factors in our eating habits which make us fat. The main factor that causes us to put on weight is our consumption of refined carbs, especially sugar, high-fructose corn syrup, and flour. When on the Atkins Diet, the dieter's body's metabolism switches from burning glucose as fuel to burning its own stored body fat - this switching is called ketosis. When our glucose levels are low our insulin levels are low. Ketosis kicks in when our insulin levels are low. In other words, when our glucose levels are low our bodies switch to using our own stores of fat as a source of energy. Our insulin levels, because of our low glucose levels, are low just before we eat. As soon as we eat our glucose levels rise, which triggers our insulin levels to rise. Refined carbohydrates are full of glucose which enters our blood rapidly. Other types of carbs, what we call "good carbs" do not have such a strong impact on blood glucose levels, compared to refined carbs. During ketosis, some of the fat (lipid) stores in fat cells are transferred to the blood (lipolysis). According to Dr. Atkins' New Diet Revolution, a diet which is low in carbs triggers a metabolic advantage - the body burns more calories than it would on other diets. During this metabolic advantage the body also gets rid of some unused calories. According to a study published in The Lancet such a metabolic advantage does not happen - saying that lower calorie consumption is the cause of the weight loss.”
What Is The Mediterranean Diet? What Are The Benefits Of The Mediterranean Diet? “What does the Mediterranean Diet include? • Lots of plant foods • Fresh fruit as dessert • High consumption of beans, nuts, cereals and seeds • Olive oil as the main source of dietary fat • Cheese and yogurt as the main dairy foods • Moderate amounts of fish and poultry • No more than about four eggs each week • Small amounts of red meat each week (compared to northern Europe) • Low to moderate amounts of wine • 25% to 35% of calorie intake consists of fat • Saturated fat makes up no more than 8% of calorie intake The Mediterranean diet is known to be low in saturated fat, high in monounsaturated fat, and high in dietary fiber.”
What Is The Zone Diet? What Are The Benefits Of The Zone Diet? “For the last few hundreds of thousands of years we have spent most of our time eating two food groups: • Lean protein • Natural carbohydrates, such as fruits and fiber rich vegetables Our genes are still those of the hunter-gatherer, rather than the farmer. Farming is a relatively new phenomenon, as far as our genes are concerned. In other words, our genes have not yet adapted to consuming farmed products. Although our genes are programmed to gather fruit and vegetables and catch the occasional prey, we are consuming huge quantities of very dense, highly processed carbohydrates, such as grains and products made from grains. Pasta, bread, corn flakes, bagels, etc. are generally made from highly processed carbohydrates. As we are not programmed to consume large amounts of processed carbohydrates, and we experience unpleasant biochemical reactions to that consumption. The consequences include weight gain, insulin fluctuations, diabetes, heart disease, and generally bad health. The Zone Diet takes into account our genetic makeup. With the Zone Diet, Dr. Sears says, we consume the fuel our bodies really need for optimum health.”
