Nutritional research vindicates diet programmes

03.09.2008
Popular slimming programmes do result in reduced energy intake while providing enough nutrients.

A new scientific analysis, published today in BioMed Central’s open access Nutrition Journal, provides comprehensive dietary data about Slim Fast, Atkins, Weight Watchers and Rosemary Conley’s “Eat Yourself Slim” Diet & Fitness Plan.

Helen Truby worked with a team of academics from United Kingdom universities who studied the different diet plans. She described how the randomised controlled trial “provides reassuring and important evidence for the effectiveness and nutritional adequacy of the four commercial diets tested”.

Truby and her colleagues asked 293 people from five regional areas around the UK to keep a diary of their food intake before and during the two-month diet period. There was also a control group who continued to eat as normal. They found that following any of the four diets did result in a drop in energy intake. The diets all resulted in a significant drop in body weight compared to the non-dieting controls, but there was no significant difference between the diets in the amount of weight lost.

Despite the fact that all of the diets apart from Atkins advise people to increase their fruit and vegetable intake, the authors found that the only dieters to do so were those on the Weight Watchers diet, and even they only had one more portion a day. According to Truby, “These disappointing findings suggest that people remain resistant to the advice to ‘eat more fruit and vegetables’, even when they are advised to as part of a modified weight loss programme”.

Contrary to the popular controversy about the Atkins diet, the researchers found little evidence of short-term detrimental effects of nutrient intake as a result of this low-carbohydrate plan. However, they do mention that, “Atkins dieters tended to have a reduction in iron and niacin, probably due to a fall in the intake of cereal and flour, which is fortified in the UK. They also had a generally low intake of dietary fibre overall, which may have implications for bowel health in the longer term”.

Based on their results, the authors suggest “commercial companies work in partnership with health professionals to identify high-risk clients and provide them with dietary advice that is tailored to their nutritional requirements”.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
