A new study has shed light on the effects of dieting in
relation to losing weight.
Researchers at Loughborough University have found that
exercising is more effective than dieting in limiting how many calories a
person eats.
The pilot study set out to investigate how exercising and
restricting diet changed a woman’s physical and behavioral responses to food.
12 women were first asked to restrict their diet by 3,500
kilojoules, or around 836 calories, for 8 hours. They were then invited to eat
as much as they liked at a buffet, where researchers secretly measured what
they consumed.
Following this, the researchers then asked the women to burn
the same amount of calories they had previously removed from their diet with
exercise lasting 90 minutes.
After exercising, the women Health and Fitness were then
again invited to eat freely at a buffet.
The results showed that women ate 944 calories on average at
the buffet when they restricted their diets, compared with 660 after
exercising.
This is thought to be because limiting food intake causes a
spike in the hunger hormone ghrelin and a drop in levels petitide YY, which
suppresses hunger.
Dr Stensel, a Reader in Exercise Metabolism in Lough borough’s
School of Sport, Exercise and Health Sciences, said: “We’ve shown that exercise
does not make you hungrier or encourage you to eat more - at least not in the
hours immediately following it. Our next step is to see whether this benefit
continues beyond the first day of exercise.”
The amount of exercise you need to do to lose weight is
beyond most people. This study highlights the level of self-motivation needed
to lose weight, you are fighting physiology by eating less.
