2013 AHA/ACC/TOS Guideline for the Management of Overweight

Guidelines and Expert Consensus documents aim to present management and recommendations based on all of the relevant evidence on a particular subject in order to help physicians to select the best possible management strategies for the individual patient, suffering from a specific condition, taking into account not only the impact on outcome, but also the risk benefit ratio of a particular diagnostic or therapeutic procedure. The ESC recommendations for guidelines production can be found on the ESC website†.

In brief, the ESC appoints experts in the field to carry out a comprehensive and critical evaluation of the use of diagnostic and therapeutic procedures and to assess the risk–benefit ratio of the therapies recommended for management and/or prevention of a given condition. The strength of evidence for or against particular procedures or treatments is weighed according to predefined scales for grading recommendations and levels of evidence, as outlined below. Once the document has been finalized and approved by all the experts involved in the Task Force, it is submitted to outside specialists for review. If necessary, the document is revised once more to be finally approved by the Committee for Practice Guidelines and selected members of the Board of the ESC.

The ESC Committee for Practice Guidelines ( CPG ) supervises and coordinates the preparation of new Guidelines and Expert Consensus Documents produced by Task Forces, expert groups, or consensus panels. The chosen experts in these writing panels are asked to provide disclosure statements of all relationships they may have, which might be perceived as real or potential conflicts of interest. These disclosure forms are kept on file at the European Heart House, headquarters of the ESC. The Committee is also responsible for the endorsement of these Guidelines and Expert Consensus Documents or statements.

 
| Classes of recommendations |
|:-------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| Class I | Evidence and/or general agreement that a given diagnostic procedure/treatment is beneficial, useful, and effective |
| Class II | Conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of the treatment or procedure |
|  Class IIa | Weight of evidence/opinion is in favour of usefulness/efficacy |
|  Class IIb | Usefulness/efficacy is less well established by evidence/opinion |
| Class III | Evidence or general agreement that the treatment or procedure is not useful/effective and, in some cases, may be harmful |

ESPEN guidelines on definitions and terminology of clinical nutrition

Obesity is a chronic metabolic disease characterised by an increase of body fat stores. It is a gateway to ill health, and it has become one of the leading causes of disability and death, affecting not only adults but also children and adolescents worldwide. In clinical practice, the body fatness is estimated by BMI, and the accumulation of intra-abdominal fat (marker for higher metabolic and cardiovascular disease risk) can be assessed by waist circumference. Complex interactions between biological, behavioural, social and environmental factors are involved in regulation of energy balance and fat stores. A comprehensive history, physical examination and laboratory assessment relevant to the patient's obesity should be obtained. Appropriate goals of weight management emphasise realistic weight loss to achieve a reduction in health risks and should include promotion of weight loss, maintenance and prevention of weight regain. Management of co-morbidities and improving quality of life of obese patients are also included in treatment aims. Balanced hypocaloric diets result in clinically meaningful weight loss regardless of which macronutrients they emphasise. Aerobic training is the optimal mode of exercise for reducing fat mass while a programme including resistance training is needed for increasing lean mass in middle-aged and overweight/obese individuals. Cognitive behavioural therapy directly addresses behaviours that require change for successful weight loss and weight loss maintenance. Pharmacotherapy can help patients to maintain compliance and ameliorate obesity-related health risks. Surgery is the most effective treatment for morbid obesity in terms of long-term weight loss. A comprehensive obesity management can only be accomplished by a multidisciplinary obesity management team. We conclude that physicians have a responsibility to recognise obesity as a disease and help obese patients with appropriate prevention and treatment. Treatment should be based on good clinical care, and evidence-based interventions; should focus on realistic goals and lifelong multidisciplinary management.

European Guidelines for Obesity Management in Adults

The development of consensus guidelines for obesity is complex. It involves recommending both treatment interventions and interventions related to screening and prevention. With so many publications and claims, and with the awareness that success for the individual is short-lived, many find it difficult to know what action is appropriate in the management of obesity. Furthermore, the significant variation in existing service provision both within countries as well as across the regions of Europe makes a standardised approach, even if evidence-based, difficult to implement. In formulating these guidelines, we have attempted to use an evidence-based approach while allowing flexibility for the practicing clinician in domains where evidence is currently lacking and ensuring that in treatment there is recognition of clinical judgment and of regional diversity as well as the necessity of an agreed approach by the individual and family. We conclude that i) physicians have a responsibility to recognise obesity as a disease and help obese patients with appropriate prevention and treatment, ii) treatment should be based on good clinical care and evidence-based interventions and iii) obesity treatment should focus on realistic goals and lifelong management.

Management of obesity in adults: European clinical practice guidelines

Obesity has proven to be a gateway to ill health. It has already reached epidemic proportions becoming one of the leading causes of death and disability in Europe and world-wide. Obesity plays a central role in the development of a number of risk factors and chronic diseases like hypertension, dyslipidaemia and type 2 diabetes mellitus inducing cardiovascular morbidity and mortality. Therefore weight management plays a central role in controlling the respective risk factors and their consequences. Obesity is a complex condition of multifactorial origin. Biological but also psychological and social factors interfere to lead to excess body weight and its deleterious outcomes. Obesity management cannot focus any more only on weight (and BMI) reduction. More attention is to be paid to waist circumference (or waist-to-hip ratio, especially in females), the improvement in body composition (measured with body composition tracking systems like BOD POD, dual energy X-ray absorptiometry or bioelectrical impedance analysis) which is focusing on ameliorating or maintaining fat-free mass and decreasing fat mass. Management of co-morbidities, improving quality of life and well-being of obese patients are also included in treatment aims. This statement emphasises the importance of a comprehensive approach to obesity management.

An EASO Position Statement on Multidisciplinary Obesity Management in Adults

Bariatric surgery is today the most effective long-term therapy for the management of patients with severe obesity, and its use is recommended by the relevant guidelines of the management of obesity in adults. Bariatric surgery is in general safe and effective, but it can cause new clinical problems and is associated with specific diagnostic, preventive and therapeutic needs. For clinicians, the acquisition of special knowledge and skills is required in order to deliver appropriate and effective care to the post-bariatric patient. In the present recommendations, the basic notions needed to provide first-level adequate medical care to post-bariatric patients are summarised. Basic information about nutrition, management of co-morbidities, pregnancy, psychological issues as well as weight regain prevention and management is derived from current evidences and existing guidelines. A short list of clinical practical recommendations is included for each item. It remains clear that referral to a bariatric multidisciplinary centre, preferably the one performing the original procedure, should be considered in case of more complex clinical situations.

Obesity is a chronic metabolic disease affecting adults and children worldwide. It has become one of the leading causes of death, as obesity is known to be the main risk factor for a number of non-communicable diseases, in particular type 2 diabetes. This close relationship led to the connotation 'diabesity', highlighting the fact that the majority of individuals with diabetes are overweight or obese. Until today the BMI is still used to classify overweight and obesity. Since reduced muscle mass is highly prevalent throughout the BMI range, the measurement of body composition is strongly recommended. Moreover, it is essential for monitoring the course of weight reduction, which is part of every effective anti-obesity treatment. Weight reduction can be achieved via different weight loss strategies, including lifestyle intervention (diet and exercise), pharmacotherapy, or bariatric surgery. However, not all of these strategies are suitable for all patients, and any further needs should be considered. Besides, attention should also be drawn to concomitant therapies. These therapies may promote additional weight gain and further trigger the deterioration of blood glucose control. Thus, therapeutic strategies are warranted, which can be easily used for the management of obese patients with type 2 diabetes to achieve their glycemic and weight loss goals.
