The seven prevalent myths about weight loss

Some of the erroneous views about weight loss and prevention of obesity, surprising and doctors themselves are that:

§  Breastfeeding protects the child against obesity

§  The gym at school prevents childhood obesity

§  The gradual loss of weight is preferable to rapid

§  The hundreds of calories by having sex

The above are just some of the myths surrounding obesity and identified by an international team of doctors led by Dr. David Allison of the University of Alabama at Birmingham.

"These data are diffuse sites, newsletters and even in the scientific literature, despite conflicting scientific evidence," explain the researchers identified seven myths and six additional concepts that have not yet been established whether it is right or wrong.

The seven myths prevalent

1st Myth: Small changes in energy intake or expenditure produce large, long-term weight changes. This seemingly logical approach based on the rule that the loss or weight gain of one pound comes from the consumption expenditure or 3.5000 calories. The problem is that this only applies in the medium term. The extra pounds are increasingly difficult to "go" when you start to lose weight. This is because, in part, as you lose weight the body has lower energy requirements that can maintain the weight (without any loss) with fewer calories.

2nd Myth: The realistic targets in the treatment of obesity is important because different patients get nervous and lose less weight. Who can argue with this finding? Dr. Alison lists however is evidence that people do better when they have more ambitious goals.

3rd Myth: The gradual weight loss is better than fast weight loss because weight lost can quickly be switched equally quickly. This myth is about 50 years, without relying on a reasonable basis. In fact studies have shown that people who lose weight quickly are more likely not to retake for many years after.

4th Myth: People who feel ready to lose weight are more likely to have to make changes in their lifestyle. The feeling ready is not bad. But studies show that the degree of readiness or willingness to diet does not provide the range of weight loss or diet program compliance.

5th Myth: The fitness classes at school, in the form made ​​today, play an important role in reducing or preventing child obesity. But in fact, studies show that increasing the number of days that children do gymnastics at school does not reduce childhood obesity. Scientists speculate that this is due to the fact that the type of exercise (in the frequency, intensity and duration) is not enough to promote sustained weight loss. Or the obese children who most need it, do not move as much as other children.

6th Myth: Breastfeeding protects children from future obesity. Breastfeeding has many protective effects for the child, such as the increase of IQ and innate immunity, but protection from obesity is not included in them. Although support for this belief is passionate, large studies recently found that not breastfeeding history plays a role in obesity.

7th Myth: An intercourse can help you burn up to 300 calories. Possibly be worth a try! But the team led by Dr Alison has estimated that a 68 kg man will burn about 250 calories per 60 minutes of intense and lasting sex. However, several are surveys conclude that sexual contact should take no longer than six minutes, ie much burn 20 calories more than if you are sitting and watching TV.

Among the views that have not yet been established whether it is true or false is:

·        Snack foods contribute to weight gain,

·        Eating breakfast regularly prevents weight gain,

·        Walking and cycling reduce obesity rates,

·        Lasting weight loss and gain causes premature death.

·        Between views is proven that:

·        Exercise improves health whether conducive to weight loss,

·        Genetics is not destiny, that anyone can have a healthy weight.
