This is my 1st time at this forum, I normally post over at the prostate cancer(PC or PCa) forum, where we often post about
many OT subjects, including heart disease, blood sugar and the possible relationships of high insulin levels to PCa and other cancers. I am not actually diabetic- not yet at least- but I am very interested in the subject of insulin resistance/high blood insulin and it's possible relationship to cancer. Sometime the guys at the PC forum don't seem as interested in th subject of insulin as I am, and it finally occurred to me I should post some of this stuff at the diabetes forum. So here I am. Hopefully this is OK, and not too far OT? Well, I guess I will soon know! LOL!
So anyway, I just posted this over at PC forum, and I am going to repeat it here:
I am a fan of Dr. Greger's web site, so I occasionally post stuff from his website here. I do find much of his info regarding which plant foods might be best in the fight against PCa, cancer and overall health in general, to be quite interesting. But recently he has been on a kick saying the CAUSE of insulin resistance and diabetes(and all the related health problems that go with it of course) is dietary fat in general and most especially saturated fat. Mind you: not fat PLUS high carbs, but fat itself is the cause of insulin resistance which leads to diabetes which leads to heart disease and various cancers. And he has studies to back him up. Here is one example of what he has to say about
However, the idea that fat- and not carbs- causes insulin excess goes against what I have always been taught is the very reason for insulin and insulin spikes and finally insulin resistance/diabetes(i.e. insulin is generated #1 in response to rising blood sugar(carbs consumed), less so to protein, virtually not at all for fat).
Also, I have seen many studies over the years, including clinical trials, that indicate both blood sugar and insulin are markedly lower in response to the cutting carbs and increasing dietary fat. There are plenty of studies out there on this subject that seem to directly contradict what Dr. Greger is saying-and backing up with his studies. He is of course a gung ho vegan, and I have never seen a study on his web site contradicting his vegan stance, of course. Still, he does have his studies to back up his theories.
This is what is so frustrating about
trying to learn anything by following the supposedly unbiased
and scientific studies. I just don't see how studies done by reputable scientists can so frequently contradict each other! Can we really believe any of them? Very frustrating. Which is why I sometimes end up also going by personal experience( sometimes just mine, but some times the addition of friends experiences), especially when successful based on weight loss and blood tests, blood pressure, etc.But here is my question:
Why should I not believe this study(and of course many more like it)? What is there about
this study that would make it inferior to the studies that show just the opposite of this one? This study is from UC Davis and SF, Indiana U school of Public Health, etc. Is there something that would make them not trustworthy? Would they have some bias causing them to want me to consume more fat and fewer carbs? That seems unlikely. Here is the link:www.ncbi.nlm.nih.gov/pmc/articles/PMC3981696/
Here is a table from that study:www.ncbi.nlm.nih.gov/pmc/articles/PMC3981696/table/pone-0091027-t003/
If you will look at that table, you will see that virtually every parameter improved or at a minimum was no worse on the high fat, low carb ketogenic diet(LCK) that did not restrict calories, vs the calorie restricted low fat, moderate carb diet(MCCR)
Particularly notable is that on the MCCR diet, blood sugar barely nudged down from 140 to 139, compared to dropping by 11 in the high fat group(who ate however much they wanted). More importantly, insulin increased by 10% from 10 to 11 in the MCCR group, but DROPPED 25% from 12 to 9 in the high fat group.
And, also as important regarding insulin: 44% of the high fat group were able to discontinue one or more of their diabetes meds compared to only 11% of the low fat/low calorie group.
Unless these researchers are either lying or incompetent( I see no reason to think they are either), if(as Greger's studies claim) saturated fat is the cause of increased insulin and insulin resistance, how could these results be possible? Thanks in advance for your thought and comments. Especially regarding why I should believe Greger's reported studies instead of studies like these? Thank you all for any insight, even if you disagree with me!
