survey says : Yo-Yo Diets Can Cause Depression

You certainly have seen many examples of people successfully lose weight, but in a few years later had returned to the original weight (maybe even more weight). Kirstie Alley, who followed the Jenny Craig diet program, renewed increase in returns of 31 kg. You also know how Oprah Winfrey's all-out fight slimming body.
Their experience clearly makes you stress. If the most influential women in America, which is always accompanied by a personal trainer and private chef just could not fight against obesity, how about you?
According to estimates, more than 80 percent of people who lose weight will continue to push their weight after two years. Researchers from the University of California at Los Angeles analyzed 31 studies on long-term diet. They found that about two-thirds of people who diet will make his weight increased more in four or five years since managed to lose weight.
This makes the Dieter's frustration. Not only because the weight must be re-imagined to lose weight, but also because of his health threat. Cycle-ride up and down this potentially causing high blood pressure, high cholesterol, diabetes, depression, heart disease and cancer.

Emotional problems
No doubt, the people trying to lose weight, there will be minor fluctuations. This is perfectly normal. That is not normal is if there was an increase or decrease in body weight significantly, at least about 4.5 kg or more and occur repeatedly.

Yo-yo dieting (the term is introduced to Kelly Brownell, MD, director of the Rudd Center for Food Policy and Obesity at Yale University in the 1980s) are also believed to be the result of a too strict diet. Their study, published in the journal Obesity states, people who follow a diet (very) low calorie will raise the weight back, rather than specifying a more healthy diet. Low-calorie diet is usually done by people who hope soon to get the results.
"If you lose weight by consuming 1200 calories a day, once you add the number of calories to 1300, that's when your weight back up," says Judith Beck, PhD, director of the Beck Institute of Cognitive Therapy, and author of The Beck Diet Solution.
The increase and decrease in body weight drastically and repeatedly feared can change your physiology. The more diets you do, the harder it is to be thin. This is because the hunger hormone (ghrelin) increase, and satiety hormones (Leptin) decreases, so you feel more hungry and did not immediately fill.
Evidence also shows, yo-yo dieting is not just a physical problem, but also emotional. Studies conducted at Brown University found that dieters who ate to cope with stress or loneliness, or the things that caused by external factors, will tend to come back fat.
According to Beck, people who fail like this never learn what it takes to change behavior in the long term. "They never taught how to motivate themselves every day," he said, "or how to respond to negative thoughts and realize a mistake as something that happens only once."
When you apply a strict diet, and your weight back quickly, you'll lose a lot of muscle and gain fat, according to Keith Ayoob, MD, RD, a visiting professor at the Albert Einstein College of Medicine. Because muscle burns calories 10 times more than does fat, "you metabolism will slow down, which means it will be more difficult to eliminate the weight further," said Ayoob.
When weight loss continues to rise and fall, the elasticity of your skin decreases, and weight loss would cost the arteries and order system. This can make your liver "stress" as it is covered in fat. Studies in Clinical Cardiology and even found that women who weighed up and down five times or more throughout their lives, will slowly damage the heart.
