ABSTRACT The increasing global prevalence of obesity urgently requires an implementation of efficient preventive and therapeutic measures. Weight loss and its maintenance should be considered one of the most important strategies to reduce the incidence of obesity-related co-morbidities such as diabetes and cardiovascular diseases. Lifestyle modification focused on diet and physical activity represents the essential component of any kind of weight management. However, only an intensive lifestyle intervention can be efficient in terms of long-term weight loss. Anti-obesity drugs affect different targets in the central nervous system or peripheral tissues and improve regulatory and metabolic disturbances that contribute to the development of obesity. Anti-obesity medications provide modest additional fat loss to that achieved by lifestyle modification alone, reduce visceral fat stores, improve programme adherence, weight loss maintenance, diminish obesity-related health risks and improve a quality of life. Anti-obesity drugs do play a role in weight management. Their replacement with placebo is followed by weight regain. Due to adverse events, several anti-obesity drugs were withdrawn from the market over the past few years and currently only orlistat remains available for long-term obesity management. Drug withdrawals, failure of clinical trials with several new anti-obesity compounds as well as inappropriate demands of drug regulating agencies concerning the study protocol led to scepticism about the perspectives in the pharmacotherapy of obesity. However, recently developed anti-obesity medications such as gut hormone analogues and drug combinations provided encouraging results in terms of weight loss, safety and improvement of cardio-metabolic health risks.

    • "Several brain circuits regulate body weight by using a variety of neuropeptides and transmitters, and are responsive to endocrine and metabolic signals are now well known and targeting them with novel pharmaceutical drugs would be helpful additions to lifestyle interventions for the treatment of obesity [60]. Recently developed anti-obesity medications such as gut hormone analogues and drug combinations provide encouraging results in terms of weight loss, safety and improvement of cardio-metabolic health risks [59].

    ABSTRACT: The definition of the Metabolic Syndrome (MS) has encountered difficulty in reaching a universal consensus although there exists an agreement of its main pathologies which are hypertension, obesity, dyslipidemia, insulin resistance, inflammation and renal damage. The prevalent opinion is that three of those alterations may define the syndrome. The incidence of the MS has increased globally, particularly in the last few years, to the point of being regarded as an epidemic. The treatment of the MS can be approached from different angles, since it may be a multifaceted health problem. A healthy lifestyle, which means the practice of regular exercise is suggested to MS patients. Increasing physical activity has anti-inflammatory effects since there is an inverse association of physical activity and inflammatory biomarker concentrations. An adequate diet is recommended, such as the Mediterranean, which contains fish, tomatoes, garlic, red peppers, olive oil and includes red wine, that is, antioxidants and non-saturated oils. There are also the traditional herbal preparations, used in the alternative medicine. Several therapeutic tools can be used; the most common are the pharmaceutical products to deal with obesity, hypertension, dyslipidemias, diabetes and inflammation. In addition several pharmacological therapies such as non steroidal anti-inflammatory drugs are recommended. Recently new mechanisms of action of statins, fibrates, metformin and thiazolidinediones have demonstrated their anti-inflammatory effect and potential use to treat MS.

    ABSTRACT: Aging is accelerated when metabolic and cardiovascular diseases (CVD) are present and the risk of these diseases increases with age. Many predisposing conditions which increase in prevalence during aging, such as obesity, insulin resistance, inflammation, changes in the activity of the hypothalamus-hypophysis suprarenal axis, stress and hypertension also contribute to increase prevalence of metabolic syndrome (MS) and CVD and will be discussed in this paper. Aging and MS are frequently accompanied by several pathological conditions and some associated phenomena such as increased lipoperoxidation, generation of free radicals, increased peroxidation of nitric oxide (NO) to its toxic species, and others, resulting from oxidative stress which significantly alter the incidence of CVD. The better knowledge of mechanisms linking MS to increased CVD prevalence has led to new predictive measures and to the study of different possible new therapeutic strategies in elderly patients and patients with MS. Preventing and treating MS and CVD would be useful in promoting normal aging.
