Laparoscopic changeable gastric banding (LAGB) will not just yield unwanted weight lack of up to 55% 24 months post-operatively, but also promotes the remission of diabetes (74%), hypertension (54%), dyslipidaemia (40%) and sleep apnoea (94%).53 The Longitudinal Assessment of Bariatric Surgery (LABS) consortium have reported no mortality at thirty days post-LABG (n=1,198).54 More prevalent small complications include oesophageal pouch dilatation (11%) and gastroesophageal reflux, whereas main complications include band slippage (7.9%) and erosion ( 1%).55C57 Roux-en-Y gastric bypass In Roux-en-Y gastric bypass (RYGB), the abdomen is divided at its higher component, which forms a little proximal abdomen pouch.58 The tiny intestine is separated on the jejunal level also, where in fact the distal area of the intestine is mounted on the new abdomen pouch. the results of this record at heart, with the purpose of giving an in depth summary of current strategies in the administration of obesity. Dietary therapy Weight loss can be achieved by a net deficit of kilocalories (units of energy). The estimated energy expenditure per adult kilogram of body weight is approximately 22 kcal.9 Reduction of intake to yield a net energy deficit can be achieved in numerous ways, as outlined below (Table ?(Table22).

Recent meta-analysis of low-fat diets shows significant weight loss when compared to baseline intake (-5.41 kg), but not when compared to other dietary interventions, including high-fat diets.11 Low carbohydrate diets (LCHDs) yield rapid results with greater initial weight loss compared to low-fat diets (by up to 3.3 kg at 6 months).12 However, much of this has been attributed to loss of glycogen stores and water, amounting to 1C2 kg within the first 14 days, after which the rate of weight loss slows.13 Protein is highly satiating and used in high protein diets (HPDs) with the aim of reducing passive overconsumption of other less satiating and more energy-dense macronutrients.14 However, recent meta-analyses have concluded that HPDs have either no effect on body weight, or a small effect of questionable benefit.15,16 Calorie restriction Another approach to achieving a net energy deficit is by directly limiting calorie ingestion. Low and very low calorie diets (LCD and VLCD) limit energy intake to 800C1600 kcal/day and 800 kcal/day, respectively.17 VLCDs yield superior short-term weight loss when compared to LCDs (-16.1 kg vs -9.7 kg, respectively).18 Weight loss from VLCD is achieved primarily through a loss total body fat (7.8% total body fat reduction at 6 months).19 However, long-term benefits of VLCDs are less pronounced, and weight loss figures are more comparable to LCDs (-6.3% vs -5%, respectively) due to higher rebound weight gain (61% vs 41%, respectively).18 This long term pattern of weight loss with VLCDs is independent of its initial rate, and is Hyal2 further supported by a systematic review by Franz em et al /em , noting a 17.9 kg (16%) weight loss at six months, following which the weight loss benefits of VLCD begin to wane (-10.9 kg or -10% at 12 months and -5.6 kg or -5% at 36 months).20,21 There are numerous reasons for the weight re-gain seen with low calorie diets, ranging from metabolic adaptation to practicalities of calorie counting and resultant loss of diet adherence. Meal replacement Meal replacement, either full or partial, involves nutritionally replete but low-calorie substitutes for daily meals, offering an easy and convenient method for calorie intake restriction. Significant weight loss benefits of meal replacement compared to conventional calorie restriction were illustrated by a meta-analysis of six studies by Heymsfield em et Reactive Blue 4 al /em . Partial meal replacement (PMR) yielded greater weight loss at 3 months (-2.54 kg) and 1 year (-2.63 kg), with a lower attrition rate.22 Similar effects Reactive Blue 4 were demonstrated by a subsequent systematic review, where PMR yielded a 3.8 kg weight loss benefit over control diets at 1 year.20 Furthermore, Reactive Blue 4 although PMR subjects experience more weight re-gain in the long term compared to conventional diets, the overall weight loss remains greater (-7.8%.
