This review, presented at the annual Society for Endocrinology BES meeting in Harrogate, shows that lifestyle interventions provide benefits at all stages of obesity management and should be encouraged no matter what other forms of therapy are offered.
Dr Rob Andrews from the University of Bristol carried out a review of the research on weight loss methods published in international peer reviewed journals. He examined how successful different lifestyle interventions (such as exercise, diet and behavioural therapies) are in the treatment of obesity when carried out alone or in combination with other treatments such as bariatric surgery and weight loss drugs.
He found that when weight loss drugs are given on their own, with no other changes in lifestyle, they produce an average weight loss of 5 kg, the same amount of weight you lose if you go on a calorie-controlled diet and take regular exercise. However, if weight loss drugs are offered in combination with behavioural therapies, their effectiveness can be increased by over 100% (from 5 kg to 12 kg average weight loss). He found that the story was the same with bariatric surgery. Patients who exercise and lose weight prior to surgery are less likely to have postoperative complications and lose more weight at a quicker rate after surgery than those who didn’t.
Overall, this review indicates, that when treating obese patients, weight loss drugs and bariatric surgery are significantly more successful if they are offered in conjunction with improvements to diet and exercise.
Full results of the review are:
-Exercise alone produces an average weight loss of 1.8 kg. The more you exercise the more weight you lose.
-Diet alone produces an average weight loss of 5.0 kg. This effect peaks 6-12 months following the start of the diet and wanes after this point. No diet is better than any other in the long term but the greater the reduction in calories, the greater the initial weight loss.
-Behavioural therapies (e.g. cognitive therapy, psychotherapy, relaxation therapy, hypnotherapy) produce an average weight loss of 2.3 kg.
-Exercise plus diet result in an average weight loss of 10.7 kg and helps to maintain weight loss for a longer period.
-Exercise plus diet plus behavioural therapies result in the greatest average weight loss of 12-15 kg.
-Taking weight loss drugs with no changes in lifestyle result in an average weight loss of 5kg. Taking weight loss drugs, in combination with behavioural therapies, leads to an average weight loss of 12 kg.
-Patients that lose more than 10% of their body weight prior to bariatric surgery are 2.12 times more likely to achieve a 70% loss of excess body weight.
Researcher Dr Rob Andrews said:
“People often forget is that there is no quick fix to obesity. Overeating and decreased activity are the fundamental problems underlying the development of obesity. Any therapy aimed at helping obese patients must have a dietary and exercise component in order to be successful. This review shows that patients who are taking weight loss drugs or have bariatric surgery lose significantly more weight if they combine these treatments with regular exercise and a calorie-controlled diet. Maintaining a healthy, balanced lifestyle is the key to maximising and maintaining weight loss.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
