I had been introduced to the Keto Diet a few years before this documentary. It was suggested to me after my craniotomy(Lg brain aneurysm+ 3 am ongoing aneurysms). Prescribed for future brain health & because I wanted to lose about 30 lbs I had gained from 6mo. Bedrest & steroid use for any brain inflammation. I watched after implementing the Keto diet in my life and had already lost 40 lbs! After watching it, I gained a lot more knowledge of how important this natural diet can be in other aspects of life. I threw out anything that was w the smallest amount of preservatives & lost more weight. Will always implement these ways in my life as I face an uphill battle w existing brain aneurysms. I now have lowered my blood pressure too & a bit of sharper thinking & concentration!
