Brief Summary
The primary goal of this study is to assess the feasibility and biologic activity of a modified Atkins-based diet combined with short-term intermittent fasting, a GLioma Atkins-based Diet (GLAD), in patients with central nervous system GBM.

Outcome Measures
Primary Outcomes (1)
Feasibility of intermittent modified Atkins diet in patients with GBM assessed by percent of patients able to remain on the diet and achieve nutritional goals
Percent of patients able to remain on the diet and achieve nutritional goals as defined by cumulative assessment of diet records collected at weeks 4, 6, and 8 with a 60% completion defined as a positive results
8 weeks per patient
Secondary Outcomes (3)
Biologic activity measured by pre- and post-study cerebral glutamate and glutamine concentrations assessed by MRS.
8 weeks per patient
Tolerability assessed by percent of patients who have an adverse reaction of any grade attributed to the diet of possible, probable, or definite
8 weeks per patient
Dietary Activity
8 weeks per patient
Study Arms (1)
Single arm diet
OTHERIntermittent, modified Atkins diet
Interventions
All patients will be participate in the intermittent, modified Atkins diet
Eligibility Criteria
You may qualify if:
- Patients must have a clinical and histopathologic diagnosis of GBM, have completed \>80% of prescribed concurrent radiation therapy and adjuvant temozolomide without CTCEA grade 3 or 4 toxicity, and be greater than 7 months from the time of completion of concurrent chemoradiotherapy.
- Karnofsky performance status \>/= 60.
- Patients must be at least 18 years of age.
You may not qualify if:
- Patients must be of appropriate mental capacities with sufficient social support so as to be able to complete required study activities (i.e. diet record, etc) and able to provide written informed consent.
- Patients with a history of a metabolic disorder including documented defect in urea metabolism (including documented history of gout), carnitine deficiency (primary carnitine deficiency, carnitine palmitoyltransferase I or II deficiency, carnitine translocase deficiency), fatty acid metabolism, beta-oxidation defects, pyruvate carboxylase deficiency, mitochondrial function, porphyria, or nephrolithiasis.
- Severe acute infection.
- BMI \> 35.0 or BMI \< 20.0.
- Active bowel obstruction, ileus, or active or remote pancreatitis.
- Clinically significant heart failure (NYHA \>2), recent myocardial infarction, or symptomatic atrial fibrillation.
- Clinically significant renal disease (creatinine \>2.0 mg/dL, urea \>100 mg/dL).
- Clinically significant hepatic dysfunction (alanine or aspartate aminotransferase \>7 times the upper limit of normal).
- Patients with insulin-dependent diabetes mellitus.
- Conditions that may increase the risk of the diet or significantly reduce compliance (i.e. cognitive impairment, frank dementia, etc).
- Other concurrent experimental therapies.
- Milk allergy.
- Treatment with the modified Atkins diet (MAD) for any cause within the 9 months prior to study enrollment
- Patient inability to complete baseline screening 3-day diet record.
