Mechanisms of protein induced satiety for appetite control during weight loss
Alexandra M Johnstone
University of Aberdeen, UK
With the ever-increasing obesity problem comes the search for effective dietary strategies to either prevent weight gain, promote
weight loss or to maintain a lower body weight. Although one diet does not fit all, high-protein diets seem to provide a tool
to promote appetite control and hence body weight control. Dietary strategies that can help reduce hunger and promote fullness are
beneficial, since these are limiting factors for success. High protein diets, specifically those that maintain the absolute number of
grams ingested, whilst reducing calories are a popular strategy for weight loss (WL) due to the effects of protein induced satiety to
control hunger. This effect has been shown in ad libitum clinical studies lasting from 1 to 14 days, up to 6 months. In addition, greater
WL has been achieved in comparison to control diets. The mechanisms responsible for the high satiating effect of protein are not
known but likely to be around amino acid metabolism and food-gut-brain interactions linked to gut hormones. It is still not clear
exactly the amount (g or %), type of protein (vegetable, diary, animal) that is required to promote satiety thus these mechanisms will
be a focus for future research. Both the safety and efficacy of high-proteinWL diets have been questioned, particularly in combination
with low-carbohydrate advice. This has been recently reviewed with growing evidence to support the use of high-protein, moderate-
carbohydrate diets as a dietary tool to achieve weight control (30% protein, 30% fat and 40% carbohydrate).
The importance of optimizing nutritional status in patients undergoing chemotherapy and radiotherapy
Alison Burton-Shepherd
Vocare Group, UK
Chemo-radiotherapy (CRT) causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea
and vomiting with consequent worsening of malnutrition. It is well known that radiotherapy is invariably associated with mucositis,
xerostomia, dysphagia, hematological toxicities and other acute side effects, whose incidence increases when chemotherapy is also
administered and that oral mucositis incidence leads to higher unplanned breaks and delays in radiotherapy administration. In
addition, in many patients such toxicities may be very severe and even life threatening and may lead to treatment interruptions that
are invariably associated with poorer outcome. This presentation will review best practice in the nutritional management of patients
undergoing chemotherapy and radiotherapy.
