The key to this study, conducted at the University of Illinois, resides in the interactive effect that exercise has to unite with a protein-rich diet. “Both elements work together with greater efficiency, correcting body composition people lose more weight, but specifically fat, not muscle,” said Donald Layman, professor of food science and human nutrition, in that college.
A diet high in carbohydrates and low in protein reduces its effectiveness, according to Layman.

Forty-eight adult women participated in Layman’s study for four months. The members of a group followed a protein-rich diet designed to contain specific levels of leucine, one of the essential amino acids. The second group ate a diet that had higher amounts of carbohydrates.

Both groups ate the same number of calories, but the second substituted for foods rich in high quality protein such as meat, dairy, eggs and nuts, for foods high in carbohydrates such as bread, rice, cereal, pasta and potatoes.

Both diets are effectiv

e because, when you restrict calories, you lose weight. But people with high-protein diet lost more. Some experts see this as a clear metabolic advantage for protein-rich diet.

The study included two levels of exercise. One group was prescribed add walking to their habits. They walked two or three times a week, not exceeding 100 minutes of added exercise. Meanwhile, another group required to perform each week five walks and two 30-minute weightlifting sessions of 30 minutes. In both groups of dieters, the required exercise program helped preserve lean muscle tissue and lose fat. But in the group with high-protein diet and high exercise, Layman noted a statistically significant effect. This group lost more weight, and almost 100 percent of the loss was fat. In the group with high carbohydrate and intensive exercise, between 25 and 30 per cent of the weight lost was muscle.

Although this high-protein diet is successful in anyone, it seems even more effective for those with high triglyceride levels and excess weight concentrated in your abdomen, a combination of health problems known as Syndrome X.

The high-protein diet strikingly down triglycerides and had a statistically significant effect on trunk fat, both risk factors associated with heart disease. The exercise helped the people who did the diet to lose in the abdominal area a higher percentage of body fat.

Strict diet in general have a strategy for cutting calories to abstain on a number of foods, especially carbohydrates, fats, and sugar. At first you might lose a few pounds successful weight loss, but eventually you’ll be so hungry that the diet left with a vengeance to enjoy food once considered enemies.

The result is a phenomenon of yo-yo dieting, which you will return to the original body weight, even more. If you have this, would be redundant all the food taboos that have been running for months.

Research conducted by Kelly Brownell, Ph.D., a psychologist and obesity researcher at Yale University, United States, found that diet can repeatedly cause of heart disease.

In the study of people with known weight fluctuates at risk of dying from heart disease 75 percent greater than those whose weight is relatively stable. “Up to lose weight here is big enough, not just two or three pounds,” he said.

Inconsistent diet can also cause high blood pressure and redistribution of fat to the body parts are easily damaged, for example from the buttocks to the abdomen. Experts have warned people with excess abdominal fat is more susceptible to heart disease.

Remember, excessive dieting is useless. That no point is the reduction in weight slowly and gradually through lifestyle changes, such as nutrition balanced diet low in calories but still have to take a complete nutrition containing protein, fat, carbohydrates, vitamins and minerals. Do not forget to keep up with physical exercise.
