Interesting. I am not diminishing your family Doctors, they are obviously very learned; but personally I would only take direction from similarly qualified Doctors who have then studied and practically applied low carb regimes to tens of thousands such as Dr Eric Westman, Dr Sarah Hallberg and Dr Jason Fung and Dr Ted Naimen. My rationale is that it is widely known that GP's study almost nothing on food and nutrition - incidently I would say my wife has known formally more than most Doctors across the globe, due to being initially a qualified PT in her teens, then getting a Sports Science Degree, followed by a Physiotherapy Degree. The latter 2 disciplines were heavy on food and nutrition (obviously geared towards sports and rehab, but kind of relevant); however much of this around high carb low fat she has now junked.
It is ok to believe that low cholesterol is appropriate as I assume you have weighed up the "evidence" and made your choice - if you did not go through a methodology, I would remind you that it was and still is a hypothesis that high cholesterol causes heart disease - following my regime, my QRISK has gone down by over 200%, the CAC scan has single handedly destroyed the Diet Heart Hypothesis in my view and I am aware tests such as the Womens Health Initiative do not produce the results the statin companies would like (amongst others). In addition my HS-CRP and Trigs are at 0.3, with HDL circa 2.5.
It is great that you have got spikes below 7, this would be good for many Type 2's. I am only showing by way of contrast that mine are below 6 on animal nutrition and low GI veg, nuts and berries, but where some would say have a palm sizes steak, I have 2 or another animal protein. I do recommend muscle building for everyone, I think this is a top prescription for insulin resistance. As you eat fish quality protein uptake and synthesis should not be a problem.
Again the foods that cause cancer in my view have been never shown to actually do so. If you take a smoker, a person who eats McDonalds / Burger King / KFC, eats crisps, pasta, rice, chips never exercises, also eats bacon and then say bacon causes cancer because this persons chances of getting colorectal cancer goes to 18% - you're at best a wilful deceiver and at worst a liar as the real number is a change in risk from 5 in 5500 to 6 in 5500. I call this slight of hand. If meat causes cancer why does the highest meat eating population in current times (Hong Kong), have the longest lived. We should also see higher incidents of cancer in populations in the Amazon and count any decade across the globe since 1900 up circa 1980 (except American) to see the incidence of most modern ills as a percentage of the population.
Good luck, how you feel and some bio markers rule.
