The gist of the article is that a number of good but small studies are showing a diet high in protein/fat and low in grain/starch carbohydrates helps you lose weight faster, improves cholesterol ratios, lowers blood pressure and generally improves vascular inflammation. In other words, lean meat and non-starchy veggies are good for you, and a high fat diet doesn't really mean your cholesterol will surely rise.
I wrote about this years ago, quoting Stephen Holt, MD. He described a 'Syndrome X' as a hidden epidemic estimated to affect 70 million Americans. This syndrome is defined by a highly variable combination of obesity (body mass index greater than 27), high blood cholesterol and high blood pressure, with the pivotal underlying problem of insulin resistance. Folks, starches and refined grain (simple carbohydrates) are the culprits here. And as it turns out, proper fats and complex carbohydrates found in veggies and whole grains are good for you.
Insulin resistance is not really diabetes, but is widely thought to lead to Type 2 diabetes. The current thinking is that for most of us, as we age, our bodies become accustomed to having to digest too much sugar outright as well as problems created from eating too many refined carbohydrates. Our systems produce too much insulin for too long, and that creates hormonal imbalances across the board, ending up with love handles, potbellies and well-padded child bearing hips.
That's not the worst of it though -- when one hormone is out of balance, it throws the entire hormonal system off balance, which can add to high blood pressure, high cholesterol, being overweight and causing plenty of trouble for menopausal women. Going on a low fat diet can actually create more problems if hyperinsulinemia (insulin resistance) is the real problem.
It all reminds me of a Woody Allen movie in which he goes to the future and finds that everything we now think is bad has been proven to be good. Comedy and life -- I'm glad to be able to laugh.
