Surgery and drugs alone are not enough to combat obesity

10.04.2008
A review of research examining the effectiveness of different obesity treatments has concluded that no matter what other forms of therapy are offered, changes in lifestyle are imperative if patients want to maximise and maintain their weight loss.

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.”

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...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

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...
