Edit: Just fyi emphysema isn't cancer. ------------------ I am assuming the emphysema is due to underlying cancer. https://www.sciencedaily.com/releases/2020/05/200512151941.htm Take large spread out doses of vitamin C (it's really cheap - but don't overdo it), and eat only 1 meal per day in a few hour window in the evening. If you are so hungry you can't function while fasting, eat sugarless vegetables that DO NOT raise your blood sugar at all: celery, radishes, etc. You only drink water from now on. In order to maintain your weight, during your 2 hour eating period, eat very calorie dense foods like dates and non corn-syrup based ice cream. Perhaps make your own super calorie dense milkshakes using whole milk / heavy cream and butter. You're going to hate this, but eat a huge amount of raw vegetables. As wide of a variety and as much as you can (obviously only in your 2-3 hour eating window). I'd do 8 pm to 10 pm. Having approximately 20 hours per day of ultra-low blood glucose levels is going to give you a good shot at getting out of this. Results by July God-willing. There are no cheat days here. Most importantly, make a lot of supplication to God. I swear to you that every single one of us will either enter heaven or hell after judgment.
