I will summarize my findings hopefully to assist others on similar journeys.
Background: Male, 77, underwent a double bypass open heart surgery, DM2 for 19 yrs
Since April 2018 I have been on modified keto diet (without measuring my carb and high fat daily intakes) and am quite happy with results. I lost 22 lbs and remain at my weght target. Also I removed high blood pressure, beta blocker, ace inhibitor and metformin prescription pills. I remain only with statin because of LDL above optimal, although my trigs were significantly reduced and HCL increased. My HgA1C three month values dropped to 5.7-5.9, from 7.3 in Jan 2018.
