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: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
