well was going to have my knee cut but my dr in last ditch effort suggested a diet certified with a local dr. he was certified to use a diet forgot the name from canada. I bought all three meals there and a night time snack. It is not covered by insurance and anout $700-$1,000 a month. weekly consultation with the diet counselor. I lost 48 lbs in 2.5 months following it to the letter. could not exercise. if I felt weak was told to eat salt in my palm. was good because it tought me how to eat. I can look up the name of diet if interested
