I tried the same thing - was feeling bad so eliminated sugar - only healthy foods, no red meat and started this regime 4 mo prior to tx and 3 mo into tx. No difference
in sx or overall well being. As a matter of fact,
in order to keep my riba down I have to have have something with a high fat content or I get nauseated. A sweet roll in the morning and ice cream in the evening works well. No difference for me either way but that's how my body responds - we are all different.
