Nutritional counseling The patients' nutritional status and adequacy of dietary intake will be assessed by a nutritionist using a three day food record, biological indices (e.g. glycated hemoglobin), clinical history, and the Patient-Generated Subjective Global Assessment tool51. Anthropometric measures, including percentage of lean body mass and fat, will be measured with bioelectrical impedance and skin calipers. Nutritional care plans will focus on meeting daily protein requirements (1.2g/kg), management of cancer-related symptoms (such as diarrhea, constipation), blood glucose control, optimization of body composition (i.e. weight loss/gain if necessary) and nutrient intake through providing practical suggestions, based on actual intake, to improve macronutrient distributions of protein, fat, and carbohydrates.
