Maybe Gary Taubes already said this, but sat fats are not the culprit.
I'm reading an article by J Bruce German and Cora J Dillard, from the American Journal of Clinical Nutrition, 2004;80:550-9, for those who check references.
What the article basically says, is don't throw the baby out with the bathwater. First, what more and more of us know, "high-carbohydrate diets were recognized as contributing to the lipoprotein pattern that charcterizes atherogenic dyslipidemia and hypertriacylglycerolemia."
In short, when the food industry began to remove sat fats from foods, they substituted carbohydrates in many forms. And those carbs not only made us fatter or obese, they changed our blood lipid profile to one which is "atherogenic" or bad for our blood vessels and circulation, and they gave us high triglycerides. Thanks a lot.
More interestingly, the article points out some of the things that saturated fats, or fatty acids, do is not bad, and what's more, some have positive effects on the body. The article states that there is no strong evidence that saturated fat elevates LDL cholesterol and thus the risk of CAD. What has not been studied is the possibility that some of the saturated fats might have positive effects, since mammals have within the mammary gland the means to produce a number of saturated fats, namely butyric, caproic, caprylic, capric, lauric, myristic, palmitic and stearic acids, to ensure the growth and survival of mammalian offspring. Evolution is a funny things, and things seem to have happened for a reason.
The article notes that saturated fats are the preferred fuel for the heart, a source of fuel during energy expenditure.
It concludes that the advice to remove sat fats from the diet has made us all fatter, and has failed to have any effect on the prevalence of diabetes and cardiovascular disease.
Next time: the sat fats and what they do for us.

Sugar Sugar
Honey, ah sugar sugar,....
You are my candy girl, and you've got me wanting you.
You know the rest.
And it's a sad fact that sugar is the origin of many of our problems, personally and as a society. Not only is obesity a personal problem, it is a societal problem.
Gary Taubes did us a great favour with his research on obesity and its patterns and causes. Were it not for him, we would still be thinking that low fat diets were the Greatest!
While exercise is a must for every human being who can do it, it is more important how you eat. If you exercise at a high rate every day, but eat a high carb diet with lots of saturated fat in it, chances are you will have high triglycerides, low HDL and high LDL. You probably have a bad level of C reactive protein as well, which is an indicator of how much inflammation you have in your body.
More and more, research in places like Harvard and Duke Universities is pointing to inflammatory processes and the size of your LDL particles as good indicators of your risk for cardiac disease. And researchers are realizing that "good fats" are important in lowering some of that risk.
A lot of these risk factors are related to the amount of sugar in your diet. High glucose in the blood throws everything off.
Heck, I would even bet that women with problems with their periods that is blamed on perimenopause and other such things, are probably insulin resistant and if they embarked on a program of walking and taking something like Metformin, their problems would stop as their insulin resistance decreased. It happened to me, but I don't want to generalize to a population. My doctor was absolutely skeptical at first, but no longer. She has studied hormones and now thinks that high blood sugar is the cause for many problems.
Want to change one thing in your diet? Reduce the amount of carbs you ingest. Switch to sugar free pop, eat an egg or egg substitute for breakfast instead of that cereal from a box, and look at the yogourt and fruit that you eat, and think about how many carbs are in them. The fewer carbs, the better.

How to low carb
Some people have a real hard time figuring out how to lose weight, and when I talk to them about low carb living, they really get confused.
Most of us are nutrition illiterates. I was until I started reading articles like What if its all a big fat lie and the Soft Science of Dietary Fat by Gary Taubes. I also read his book, Good Calories, Bad Calories. What a revelation.
Then I bought a few books on metabolism that would be termed texts. And I got some from the library. I think I understand more about how my body works.
It is the why that most of my friends and colleagues don't get. "Aren't carbs good for you?" and "They are low fat." Well, no and yes. They are low fat. But they make you fat. They make your body store fat.
My kids (all adults) now understand about the few good carbs, all whole grain or super complex carbs which are relatively low GI. I tell them the trick is to eat as few of them as you can manage. Two of them go on South Beach from time to time, with some success.
In Canada, the expected intake of carbs is about 300g per day. Way too much. I try and stay around 50 g, from my breakfast cereal and bits of other things during the day. I know a lot of people who would probably eat 500g of carbs a day because they love a big serving of low fat potatoes or rice with supper.
And we eat way too much. Those of us who don't dig ditches for a living really need to eat more like birds.
It's an ongoing struggle, for sure, but low carb does work.

Fat and your body
Most people wonder what triglycerides are. Triglycerides are the fats as they are stored in your body. That stuff you want less of. It is a flag for you when your triglycerides are high, as that means there are lots circulating in your blood stream, and most likely you are in the process of storing them. They have to be broken down to get out of your cells, and that happens when you have used up (or don't have) glucose in the blood stream to burn as fuel for your body. So that is how a low carb diet burns fat: it absolutely will get fuel from wherever it can get it. And that will be the protein in your diet, and the fat stored in your body.
My husband has lost 30 pounds in the last four months on a low carb diet. He wants to lose another 10-15 lbs. He eats less than 50 g of carbs a day. I have lost 15 lbs and stay under 100g of carbs, which is one third of the recommended daily allowance in Canada. I'm sure I used to eat a lot more carbs before I knew to count carbs.
His triglycerides are now low compared to last year. His is more of a Meditteranean diet, I guess, but it is pretty low carb. We used olive oil. His HDL is good, and so is his LDL. Mission accomplished, and he walks on a treadmill. His family has high blood pressure and stroke as risk factors.
I was happy someone pointed me at "Good Calories, Bad Calories" or GCBC as its known. I recommend it.

Gary Taubes explains it so well
Watched his lecture at Berkeley again.
At the hour point, he cuts to the chase. Fat storage happens because of alpha glycerol phosphate, which is needed to bin fatty acids into triglycerides. AGP (my abbrev.) comes from burning glucose and nore is available to store fat when insulin levels are high. Want to store less fat? Keep insulin levels in the blood low. Take in less glucose.
Yalow and Berson in 1965 say "Insulin is the principal regulator of fat metabolism". Gary talks about how emaciated type I diabetics can be, as they no longer produce their own insulin. They have nothing to drive fat accumulation with. When treated with insulin therapy, Dr. Best (yes, that Dr. Best) describes how they develop adipose deposits in the stomach where the insulin is injected.
My husband and I started the South Beach Diet in late September 08. My husband has lost 25 pounds and his blood profile has improved so much his doctor is ecstatic. My husband's triglycerides are WAY down from where they were. The doctor had recommended South Beach. I have lost 17 pounds. Don't you hate men who always win in the weight loss game? My profile is improving as well. LDL and HDL levels close to normal.
It's the insulin, stupid.

Low Carb diets do work folks.
So my husband and I have been following a sort of South Beach diet, somewhere between strict phase 1 and phase 2. He of course has lost 10 lbs to my 7, which is par for the course. I don't eat fish which complicates things. I'd like to but get a scratchy throat which could mean allergies. But we've eaten chicken, beef, ribs etc, cottage cheese, cheese.....just little bread. It can be done. I've been eating carb free jello. I have sugar free coffees.
Most interesting is that my blood sugar (I'm a type2 diabetic) is now hovering between 5 and 7 all the time. My doc reduced my metformin a bit. Nice!!! My ankles aren't swollen as much, and she also reduced one of my heart meds that affect my blood pressure. I went to Pritikin in the spring and they say that losing 5% of your body weight improves your health, so I am closing in on that. I need to do it several times.
I got onto this because one of my acquaintances lost 60 lbs and improved her blood profile while doing it. She pointed me to the book "Good Calories, Bad Calories" by Gary Taubes and the rest is history, in that I am doing lots of research on the idea that carbs and therefore insulin can almost be said to be the root of most of the obesity epidemic.
Of course skinny folks don't have to worry as much except if they eat a high carb diet, of simple and easily digestable carbs. Also high fructose corn syrup is a culprit. But being fat brings its own brand of wonderfulness - high blood sugar, high insulin readings, insulin resistance. Fat doesn't just lie there, it is working all the time and affecting you.
I'll let you know how things go, and how my blood profile changes over the next while. Learning to burn fat and stay away from carbs will be interesting.
