+Detailed description

This study examine the effects of very low carbohydrate diet (in which the calories requirements are mostly from fat) to the level of systemic inflammation (measured by Glasgow Prognostic Score), serum lactate and TNF Alpha levels. The subjects are colorectal adenocarcinoma patients who were decided by experts to be managed by best supportive care. These patients are not deemed to be suitable for surgical intervention , chemotherapy or radiotherapy anymore. The main treatment is supportive. We would like to examined the effect of very low carbohydrate diet on these patients, in which theoretically tumtor cells of the colorectal adenocarcinoma needed glucose to replicate and increases the systemic inflammation response.

+Arms and interventions

ArmTypeInterventionsDescription
Very Low Carbohydrate DietExperimentalOther: Very Low Carbohydrate DietThe patient will be evaluated for baseline clinical and laboratory values, and counselled on very low carbohydrate diet.
ControlNo interventionThe patient will be evaluated for baseline clinical and laboratory values, and counselled on normal healthy .
  • Very Low Carbohydrate Diet (Other): 1 : 4 ratio of carbohydrate to fat of the total daily calories intake

+Outcome measures

Primary outcomes

  • Glasgow Prognostic Score [Change of baseline Glasgow Prognostic Score on day 21]: A score to evaluate systemic inflammation response

Secondary outcomes

  • Serum Lactate [Change of baseline Serum Lactate on day 21]: Lactate level in blood serum
  • TNF Alpha [Change of baseline TNF Alpha serum level on day 21]: Level of Tumor Necrosis Factor Alpha in the blood serum
