Why I think a diet of 55-65 % carbohydrate doesn't make sense - What do you all think?
I know it is me again. But I have a serious problem that to me is blatently obvious and yet it seems to be the opposite of how most people eat and also diametrically opposed to what is recommended by gov't health officials and most medical professionals. Here is a quote from my last post on http://www.three2treat.com
I asked a brand new, wet behind the ears Resident or Family Doc in Training how much education he received in the area of nutrition during his medical degree. His response was, "Hardly Any"
Hmmmmm. So I decided to pull a Medical Physiology Textbook written by Guyton from the shelf to have a look at what these doctors review in terms of Insulin Metabolism, and the storage of Macronutriants, like Carbohydrate, Protein, and fat. Thinking, there must be a profound reason we are offering the general public a guideline to consume a diet that contains 65% carbohydrate. So I flip it to the pertinent section. And read the following:
"In time, the insulin plays an important role in storing the excess energy substances. In the case of excess carbohydrate, it causes these to be stored as glycogen mainly in the liver and muscles. It causes fat storage in the adipose tissue. Also, all the excess carbohydrate that cannot be stored as glycogen are converted under the stimulus of insulin into fats also stored in the adipose tissue"
Okay, so they are taught in medical physiology that insulin is the main stimulus for fat storage. So I ask myself, what causes increased levels of insulin in the human body?

I am trying to figure this out. But the more I read I question if a calorie in is simply a just a calorie. There are studies, I will dig am up, but since I am suppose to be working it'll have to way, that indicate a change in metobolic pathways when consuming particular macronutrients, as the Medical text suggests. Like when a person consumes 30 grams of CHO per day, it changes that metobolic pathway to favour fat as its primary fuel source, which is neat, and I have found it personally effective.. Some of the evolutionary science behind eating is remarkable as well, and I just don't think we were designed to eat excess CHO like most folks do. Looking forward to more discussion, but I have to do some work.
Cheers!

Gary Taubes has several books on the topic. One is called something like "Why we Get Fat?" And is quite a good read. Unfortunately I'm on my phone and don't have it handy. He questions a lot of the "calories in/calories out" theory and explains how carbs are, in fact, the culprit and are not in fact necessary. This makes sense to me if only because carbs are a relatively recent development in human history.

I would agree that our bodies really are not meant to process very refined carbs. But I think Taubes and others put such an emphasis on what we eat/consume for the reason that some get fat, but not enough emphasis on how our sedentary lifestyles contribute to the problem. As you and I know, Mr AcidRock, lots of exercise is a "magic pill."

Have you read Gary Taubes book "Good Calories, Bad Calories" or "Why we get fat?"
They cover the science and studies in great detail. I also found that the "New Atkins for a New You" by Drs. Westman, Phinney and Volek had good explanations.
Gary Taubes does not believe that a calorie is a calorie or calories in vs. calories out. If you examine closely the dietary guidelines, the 45-65% of calories from carbs comes from dietary surveys. They recommend that level of carbs because people report that is what they eat. So the recommendation is that people should eat what they have been eating, and with an epidemic of obesity that is clearly a bonehead thing to do.

Anything you eat will be stored as fat if you have eaten more calories than your body is able to burn. That includes carbohydrate and protein, but yes it also includes fat. Anyone who says otherwise is trying to make mega-money by selling books about fanciful magic diets. I include Taubes in this category.

Then how do you explain me loosing four inhes off my waist in 2 months eating 30-50 gms CHO per day, and the rest of my 2000 Calories come from fat and protein? I think some of the research is legit, never mind the fanatical diet book types. Pretty interesting stuff if you actually try it and experiment on your self. But you kinda have to be open minded for that....

Actually, this is my experience. I ate over 5,000 calories a day on a very low carb diet and didn't gain any weight. Now granted, my weight is very stable, but still. If you really beleive calories in vs. calories out, I should have gained more than 50 lbs.

You don't supply enough facts. How much do you weigh? How much exercise were you getting?
What do you think happened to the fat you were eating? Did it just disappear?
You have to be more than open-minded to believe you can eat unlimited fat and not gain weight - it's a distinct benefit if you also believe in fairies.

What if I do believe in fairies??? I think that our metabolic ways are more complex then simply calories in vs calories out. Good debate leads to questions and answers for all, which is great!

(slight sarcasm) Ah, but if the equation was so simple, we would all be thin, if we only exercised more. Then the fitness and diet industry would be out of business, because losing weight would be so easy.

One thing to consider as well, how much money does Big Agra stand to make if the dietary recommendations are in line with their business model? By having a diet of 55% grains, we WON'T be able to take off the weight, control our BG, so of course that fuels Big Pharma.
I agree with you, follow the money.

Sorry Jag1 - another thing to poke a hole in your theory. If you look at the poverty levels in 3rd world countries, you find obese women who are not eating so their kids can eat. Yet, they are still getting fat. How do you account for this phenomenon using the statement, "Anything you eat will be stored as fat if you have eaten more calories than your body is able to burn?"
