Hi beepster,
I appreciate the discourse, and of course it's never wrong to watch your arteries. That said, I do think you are operating on old information there.
I am not in the Air Force - that picture comes from when I took a combat school course last summer and got to fly prop planes with laser designation; I got to play fighter pilot for a day! :)
I actually run a software company and spend a lot of time behind a desk. I just turned 48 and around 40 or so my health took a very nasty turn. I got really heavy, seemed to need anti-depressants, and all of my blood numbers were aweful.
I was also showing signs of pre-diebeties, and that scared the hell out of me.
I took it upon myself to solve my health issues. It's been a very long and winding road. For one thing, I found my testosterone had bottomed out at about 170 or so. I found a very progressive doctor and got on t replacement therapy. I also gave up all wheat and gluten about 3 years ago (one of the best things I ever did). My wife and son did as well and they will never go back. My daughter won't give it up, but she won't eat read meat, go figure. :)
When reading about wheat and the effects of genetically modified food (the wheat you eat today isn't even in the same ballpark of chromosomes as the wheat that was eaten 100 years ago), I came across the science of a keto diet. Atkins was waaaaay ahead of his time - the part that came after was needing moderate protein and HIGH fat.
If you eat low carb and high fat, your energy is always up, you are almost never hungry, and you don't have to eat much to sustain in.
Consider this:
a. A gram of carbs has 4 calories of energy
b. A gram of protein has 4 calrories of energy
c. A gram of fat has 9 calories of energy
Also consider that most natural carbs (fruits) where seasonal and very limited in each area and which form of fuel do you think the body would choose to run on?
Ug, I remember eating egg white omelets and hating them. Turns out the current research shows that we actually absorb little to no cholesterol in what we eat - our bodies actually make it. so by removing the yolks, you actually remove all the good stuff your body needs from it!
I remember switching to skim milk and hating it. Turns out again that the good fats were removed and I was left with the carbs! WRONG
If you look at the rise of obesity you will see it directly correlates with the introduction of the food pyramid.
I'm not doctor and I won't try to convince you, but I will tell you I've taken this journey under the watchful eye of an exceptional doctor with blood pulled every 3 to 6 months and a keto diet, in my humble opinion, is how humans are supposed to eat.
Do the homework - read the books! The info is out there but everyone believes the old science (research that too and see how much it was bungled and how much was political) and then decide how you want to live your life.
I am approaching 50 and healthier than I've been in 15+ years. I eat bacon almost every day and steaks at least twice a week. I put butter on everything I want to - sometimes I just eat butter by itself. A half of an avocado and an egg is plenty of good fuel for most of the day I keep my carbs below 50g a day.
I also just completed a 4 day fast a weeks ago, as did my wife.
All of us were lied to - and the obesity and heart disease epidemic in this country shows the results!
Again, for any of you not happy with how you feel - DO THE HOMEWORK.
