Keto for cancer research

Options
Hey everyone, new here but have been doing keto for about 7 weeks as part of a clinical study on the effects of strict keto on glioblastoma. The trial was supplying the meals but I preferred fresh food to frozen and reheated, so we went on our own. Is there anyone else out here doing something like this? 20 net carbs and 2000 calories daily? Pretty much no sugar as well. This is a real stretch for me as a 40 yo male who never had to watch his weight to suddenly have to analyze every meal and snack. Thanks for forums and sites like this, make life easier!
