Brief Summary:
Malignant tumor incidence showed an upgrade trend in recent years. Standard therapy for malignant tumor includes surgery followed by radiation and chemotherapy. Despite optimal treatment the prognosis remains poor. There is an urgent need for more effective therapies. The Warburg effect has been widely observed in human cancers. The main energy supply of tumor cells are aerobic glycolysis. Therefore, they are highly dependent on glucose metabolism. Recently, some scholars have suggested that 'Restricted calorie Ketogenic Diet (RKD)' might be able to inhibit glycolysis and thus anti-tumor by restricting carbohydrate intake. This will 'starve' cancer cells, which will lead to cell death. There are many animal and in vitro studies shown that RKD can reduce the tumor size and thus tumor cell growth of malignant tumors. However, a consistent positive result can not be found within a small sample of clinical trials. In this study, 40 patients with malignant tumors will be treated with or without RKD. The safety and efficacy of RKD and the patients' tolerance will be observed in order to understand whether this therapy can be a potential new treatment This clinical study is comparatively large internationally. It is the first domestically. This study is essential to extend the survival of patients with malignant tumors, and to study clinical nutrition support and its metabolic pathways for malignant tumors.

Arm Intervention/treatment
Experimental: Restricted Calorie Ketogenic Diet

Calorie restriction: The basis of dietary design is 70-85% of individual's total calories. The total calorie is based on patient's activity level and their basal metabolism values, which is obtained from indirect calorimetry or harris-benedict formula.

Treatment will consist of ketogenic diet. KD will consist of 4:1-1:1[fat]:[protein+carbohydrate].Carbohydrate is limited to 10-30 g / day.The diet will be supplemented with vitamins, calcium, phosphorus, zinc and selenium supplements to meet the requirements of US Dietary Reference Intakes (DRI) standard.

Other: ketogenic diet
The treatment is mainly restricted calorie ketogenic diet. KD will consist of 4:1-1:1[fat]:[protein+carbohydrate].Carbohydrate is limited to 10-30 g / day.

Primary Outcome Measures :
  1. Adverse events of patients on high-fat diet [ Time Frame: 2 year ]
    The main focus of this period is to recruit patients and collect clinical data for patients with glioblastoma multiforme on restricted calorie ketogenic diet. The safety and tolerability of the treatment will be evaluated.This can be measured by reports of adverse incidences.
