I was concerned about the dietary fat myself.
A couple of years ago I had an emergency in my on-line business. The company that purchased my shopping cart was giving away my wares - for free
It took 4 days to figure out the problem, and then I had to re-write the cgi code and on-line database for 600 products, one at a time. It took about a half hour per product. Aaaaarrrrgggghhhh.
In those 4 days before they figured out what the problem was, my heart was skipping beats. I was worried the stress was giving me heart attacks. So I went to my doctor who sent me to a very well respected cardiologist in town.
They did four tests (1) a monitor I wore for a week to record the skips (2) radiation to see if blood was getting to the heart (3) treadmill stress test and (4) ultra-sound to see if my circulation was good.
The doctors and staff were amazed and said my circulatory system was as healthy as someone 20 years younger than my actual age.
My wife was in the room when the ultra sound lady did my legs and actually let out a squeal of excitement to my wife about how well the blood was circulating.
I can't say if the high fat is good or bad for you, but it obviously isn't for me.
Think about this. The Inuits used to eat high fat diets before the SAD got to Alaska and then never had either cancer or heart disease. The French eat very high fat diets and have a low heart disease rate. The doctors call it the French Exception and the Inuit Exception. I call it evidence that fat is actually good for us.
But I'm no doctor. I just think for myself.
I'm 73 with a 50 year old body inside. I've been on keto since it was called Atkins Induction, and this year I caught a cold, the first in over 15 years. One day of runny nose, one day of a mild cough, and the next day I was back to normal. I spent a week in Vienna, went off plan a little to enjoy their food, and I think that's why the cold got me.
I'm convinced that keto is helping me live a longer and healthier life. I guess I'll eventually find out if I'm right or wrong.
