A spoonful of sugar helps your waistline go down

10.07.2007
New study challenges conventional thinking that high carbohydrate, low fat slimming plan should contain little or no added sugar (sucrose).

A team of scientists at Queen Margaret University, Edinburgh has found that a low-fat, high-carbohydrate diet (containing sucrose) combined with physical activity achieved the greatest health benefits in overweight subjects. The study, which will be published in the August issue of International Journal of Food Sciences and Nutrition, provides evidence that the exclusion of sucrose, as is normally advocated in a weight loss diet, is not necessary to achieve weight reduction. In fact, the palatability of sucrose may even help dieters stick to their eating plans.

As part of a 12-week programme, 69 overweight women (average age 41 years; average body mass index [BMI] 32 kg/m2) were given advice on either diet, physical activity or both. A fourth group acting as the ‘control’ received no advice. Measures of body fat and markers of heart disease risk (such as waist circumference and cholesterol levels) were collected at the beginning and end of the trial.

The advice followed healthy eating guidelines and recommended:

•a reduced daily calorie intake, which was low in fat (35% of calorie intake) and high in carbohydrates (55% of calorie intake)

•that one tenth of their total calorie intake included sugar - around the average for a British adult. To achieve this goal, subjects were advised to include high carbohydrate snacks such as low fat cereal bars and low fat yogurts (containing at least 20g sugar) between two and four times per day, depending on their energy needs.

•an increase in activity levels focused on including sixty minutes of brisk walking per day.

Writing in the International Journal of Food Sciences and Nutrition, the researchers noted that after three months, the group combining the sugar-containing diet and activity changes recorded the greatest positive health outcomes, compared with diet or exercise alone. Significant reductions were observed in body weight (4.7% loss), waist circumference and percentage body fat. Measures of blood fats (total cholesterol and LDL) had also significantly improved.

‘This research contributes to the growing body of evidence that an effective way to lose weight is by adhering to a high-carbohydrate, low-fat diet and by being physically active.’ commented Dr Drummond, adding ‘ it also provides evidence that the exclusion of sucrose, as is normally advocated in a weight loss diet, is not necessary to achieve weight reduction.’

Part of its effectiveness may be due to the palatability of sucrose, making it easier to stick to the diet. As Dr Drummond points out ‘Compliance with this palatable low fat diet was excellent and when combined with increased physical activity resulted in significant improvements in body composition for this group of overweight women.’

This study highlights the need for dietary advice to accompany increased physical activity in order to achieve weight loss. It also demonstrates that a low-fat, high-carbohydrate, sucrose-containing diet combined with increased exercise can be effective for slimming. Further studies are now required to investigate which methods will motivate overweight individuals to adopt these lifestyle changes.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
