גברים מוצלחים יותר מנישם כשמדובר בירידה במשקל, כך קובע היום (ג', 20.9.05) מחקר חדש.
מחקר שנעשה על-ידי ארגון 'Slimming World' ופורסם בעיתון "Human Nutrition & Dietetics" גילה כי בתוך 12 שבועות, 91% מהגברים שלקחו בו חלק איבדו 5% ממשקל גופם. במחקר קודם, רק 53% מהנשים איבדו כמות זו באותו מספר שבועות.
הנתונים מראים גם כי לאחר 12 שבועות הירידה הממוצעת במשקל בקרב נשים היתה 15lbs, בו בזמן שגברים ירדו 23.5lbs בממוצע.
למרות שבמדינות רבות גברים רבים יותר מנשים סובלים מעודף משקל עדיין קיימת תפיסה כללית מוטעית כי קבוצות הרזייה הן בעיקר לנשים. ועובדה זו יכולה רק לתרום גם היא לעלייה בעודף המשקל וההשמנה בקרב גברים, כשגברים חשים שלא בצדק כי קבוצות הרזייה אינן בשבילם.
המחקר הנוכחי מראה כי קבוצות הרזייה הם בהחלט אפשרות ברת ביצוע לגברים ומומלץ כי גברים הסובלים מעודף משקל והשמנה ומעוניינים להוריד את הקילוגרמים המיוצרים בהחלט ישקלו להצטרף לאחת כזו.
They looked at the attendance and weight change in 125 male Slimming World members.
Of those who had been members for 12 weeks, 91% had achieved a 5% weight loss - an amount where health improvements should be seen if a person was overweight/obese.
Successful slimmers
Of those who had been members for at least 24 weeks, 69% achieved a 10% weight loss and the remaining 31% achieved at least 5% weight loss.
Dr Jacquie Lavin, a nutritionist with Slimming World, said there were potentially a number of reasons why men might be more successful at losing weight.
One key reason is that men tend to have a higher muscle mass than women, and so burn up energy faster.
However, Dr Lavin said women who attended slimming organisations had often tried various diets over a long period of time, and become somewhat cynical about their chances of success.
Men, on the other hand, often did not have the same history of dieting, and tended to be less cynical and more motivated to follow instructions.
In addition, only those men who were very focused and determined to succeed were likely to venture into a class where the vast majority of people attending were usually women.
Dr Lavin said: "Slimming groups are a predominantly female environment but they don't have to be.
"With the number of overweight men increasing, more options need to be available.
"Men need a practical solution to slimming, one that is accessible and realistic. They want plenty to eat and they want to have a laugh at the same time."
She said Slimming World had established a number of men-only groups to help tackle this rise in male overweight and feedback from members in these groups was positive.
"Data from this study shows the approach is working but slimming groups still have a female image, something we must work to change if the health of the male population is to be improved," she said.
A spokeswoman from the British Dietetic Association said: "We welcome any initiative to help people lose weight.
"Obesity in men is a huge problem and it is associated with lots of health risks.
"Group support can help and men only groups are a positive move."
