Popular weight loss diet plans are not all created equally. Diet researchers are constantly studying the many plans currently available to determine which ones offer specific health benefits to help dieters choose the one that is right for them.
The Volumetrics’ Diet Plan is Best for Large Eaters
For people who need to eat a lot of food, the Volumetrics Eating Plan may be the best choice. Results released in June 2007 of a year-long food research study by Penn State researchers showed that diets consisting of foods that are low in calorie density, such as the Volumetrics Eating Plan, can promote healthy weight loss and help control hunger.
Low calorie density foods – such as fruits, vegetables, soup, lean meat, and low-fat dairy products – are high in water and low in fat and provide few calories per bite. This allows people to eat significant portions of food, lowering their feelings of hunger and deprivation. Participants eating the low calorie density foods lost more weight during the first six months than those on a strictly low fat diet – on average 19.6 pounds compared to 14.7. The study also showed that these same participants ate 25 percent more food by weight and experienced less hunger than those on the low fat diet.
The Atkins’ Plan Has Proven Results
If you want a diet that has proven results, the Atkins diet definitely does. The Atkins diet is a low carbohydrate, high protein diet. In March 2007, researchers at the Stanford University School of Medicine completed the largest comparison to-date of four of today’s most popular diets, and the Atkins diet finished first – making it the most proven diet. Of the more than 300 women studied, those who followed the Atkins diet for a year lost more weight than the other participants (on average 10.4 pounds) and had the largest decreases in body mass index, triglycerides and blood pressure. Their high density lipoprotein (good cholesterol) was also higher than those on the other diets. Researchers feel the Atkins diet was the most successful because it encourages low sugar or fructose intake, higher water intake, and higher protein, the latter two helping you to feel full with less food.
Dr Ornish Program Good for Those with Heart Disease
For those with a history of heart disease, the Ornish plan may be one to consider. The Ornish diet is a high fiber, low fat, vegetarian diet. Participants can eat as much vegetables, fruits, grains and legumes as they wish.
An October 2007 study from the University of Massachusetts Medical School (UMMS) found that the Ornish diet performed the best in its ability to reduce cardiovascular disease compared to several other popular diets. The study compared dietary intake such as the ratio of white to red meat, polyunsaturated fats to saturated fats, and the quantities of fruit, vegetables, nuts, legumes, fiber and trans fats consumed, all of which affect cardiovascular health.
The Mediterranean Dieting Plan Best Diet for Smokers
Heavy smokers might want to look at the Mediterranean diet. The Mediterranean plan is based on a high consumption of foods common to the region such as olive oil, fish, red wine (a mild to moderate amount), as well as fruit, vegetables, bread and wheat.
According to the results released in May 2007 of a 20 year study, the Mediterranean diet greatly reduces the chance of developing chronic obstructive pulmonary disease (COPD) such as emphysema and bronchitis. Of the 43,000 men studied, those who ate a Mediterranean diet had a 50% lower risk of developing COPD than those consuming a Western diet (processed foods, sugar, red meat), even after adjusting for age, smoking, and other risk factors.
South Beach Program Helpful to Those with High Insulin
Those with a high insulin concentration may find the South Beach diet best. The South Beach plan is a low-glycemic diet, which focuses on eating foods such as lean meat, fish, vegetables, eggs, cheese, and nuts as well as monounsaturated and polyunsaturated fats, and avoiding foods such as dairy, sugar, bread, potatoes, fruit, and alcohol, as well as trans and saturated fats (at least in phase 1 south beach diet). The result is the body loses its insulin resistance, and begins to use excess body fat for energy.
In May 2007, researchers at Children’s Hospital Boston found that after studying 73 obese young adults, a low-glycemic load diet provides more weight and body fat loss than a low fat diet for those individuals with high insulin concentration at 30 minutes during an oral glucose tolerance test.
Research studies are helpful when wanting to compare these popular weight loss diet plans and find the best diet for you. Of course, everyone should consult their doctor before trying any of these popular diet types.
