Özet:

Obesity is a chronic disease and bariatric surgery has been considered an effective treatment. However, because of the restrictions imposed by the procedure, adjustments in the diet are necessary. Therefore, the objective of this study was to estimate the amount of macronutrients present in the five preparations prescribed in the protocol for post-bariatric patients undergoing follow-up at a Nutrition clinic in the city of Cascavel-PR. Some selected preparations were prepared in a domestic kitchen and sent for physical-chemical analysis in an accredited laboratory and others were calculated through tables. Subsequently, one-day calculations of a restricted liquid diet and a prescribed complete liquid diet were performed and compared with other published works. It was possible to observe that, in terms of calories, the daily restricted liquid diet is within the range indicated by some authors, as for the macronutrient distribution, the proteins are above the recommended level. In the case of the complete net diet, a hyperproteic and hyperglycemic diet was observed. Although not all the prescribed preparations are analyzed, it can be observed that the amount of calories found in these diets of the FAG Clinic protocol is adequate and meets the daily nutritional needs. However, it is suggested that other studies including the physico-chemical analysis for all preparations be performed, because although it is a short period in the process, the more nutrients are offered, the better the result. Even after achieving the desired body weight, dietary changes must be maintained to avoid weight regain in the future.
