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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
