Effect of Vegan Diet and Lifestyle Changes on Indolent Lymphoma During Controlled Waiting Period

The aim of the present trial is to evaluate the effect of lifestyle changes on the natural history of indolent lymphomas, during the period of watchful waiting. The intervention program is comprised of specifically designed vegan nutrition, physical activity, mostly aerobic, and stress reduction by relaxation and meditation. Outcome results will be followed and analyzed for 3 years, taking into consideration the following parameters - disease burden, specific disease-related symptoms, relevant blood tests, body weight, indicators of well-being. Changes in these parameters will be correlated with the level of compliance and adherence to the intervention program. The results of the trial group of patients will be further compared to the natural history of the disease in a comparable group of patients during their waiting period who were not subject to the above intervention.
