Low Carb Back On The Table?

"In the case of low carbohydrates, people shouldn't be so quick to throw that away and move on to the next diet. Limiting carbohydrates can be beneficial even if people aren't successful at losing weight."
These are not the comments of a fad diet author, but from the head researcher (Dr Ronald Krauss) of a new study presented in the American Journal of Clinical Nutrition. Ironically this comes right after reviewing the Glycemic Load Diet (another new low-carb diet).

Design of the study

This particular research concludes that lowering carbohydrates can lower cholesterol. 178 overweight men aged around 50 years old were put on 4 different diets: 54% carb, 39% carb, 26% carb, and 26% carb with high saturated fat. From Reuters:

Compared to the men who stayed on the standard diet, those with the lowest carb intake showed reductions in harmful triglycerides and "bad" LDL cholesterol levels. They also enjoyed an increase in the ratio of "good" HDL cholesterol to total cholesterol levels, and other improvements in their blood fat profile.
A close read of the full study reveals some other interesting results.

All men in the study had daily calorie intake reduced for a period of five weeks in the middle of the study - which led to weight loss. This was followed by a 'stabilization' phase (i.e. maintenance calories). Though the research was not looking at weight loss as such - these comments are interesting:

Despite our effort to maintain constant weight, the 26%-carbohydrate, low-saturated-fat diet group lost more weight than did the 54%-carbohydrate group during the stable-weight period. There was also a trend for a greater reduction in percentage body fat with the lower-carbohydrate diets...
Krauss summarises the Reuters article by suggesting that "sugary foods, white rice, pasta, white bread" should be the first to go if we intend to reduce carbohydrate intake. Krauss also warns that "This type of diet really needs to be done in consultation with a dietitian to get the balance that we used."

To many who have successfully used low-carb diets to reduce weight and cholesterol - this study will be a 'yawn;. However, it does help to bring some balance back into the arena of popular media.

First, Let me make this clear that cholesterol and saturated fats arn't the cause of heart disease.

We ate eggs, ham, and meat products and used coconut oil back in 1900. Heart disease was very rare.

Today, Americans are eating so many grains, sugary grains, and we are raising our cattle in a horrible manner.

I am sick and tired of people trying to convince us that grains are good for us. Just a pitiful attitide from the USDA giving us a garbage food guide pyramid that packs us on the pounds causing us to eat all that "breads, cereal, rice, and pasta" for us to think that we are maintaining our health. Americans back in 1900 ate very little pasta, and ate mostly fruits, vegtables, nuts, eggs, and meat products. Farming was totally different and we didn't have factory farming today. All cows back then were fed on a grass-based diet, and chickens were naturally raised then.

Today, our foods come from filthy factory farms. Cows being feed carboard, grains, animal byproducts, rGBH pills, antibiotics, and all that crap that cows weren't designed to be fed. Fruits and vegtables today are sprayed with harmful pesticides and are on the verge of becomming genetically altered. If we still live on a diet that we had been in 1900, rich in family-farmed eggs, meat, and locally grown fruits, vegrables and nuts without all these pesticides, and we had used butter, coconut oil, and olive oil, and low on the grains, we would of been in a much better shape today.

Fokes, we can stamp out factory farms, go back to family farms, stop all these nonsense lies, and get ourselves back together after 40 years.

I am not anti carb counting I feel that carb counting under a doctor’s care for diabetics is better than the old exchange diets. I do not though think grains are evil though.
I am glad you found something that works for you.

1. Some Grains lower cholesterol.
2. Fruits even organic are simple carbs and would elevate ones insulin levels more than a bowl of oatmeal.
3. Any diet that works deals with calories. Your diet is lower calories than the one you’ve been on so you lose weight. Low carb diets have been studied and the ones that work are low calorie diets. When you remove a food group you cut calories.
4. I lost a lot of weight eating whole grains. Grains are not the devil for all people. Oatmeal has fiber and is filling. Cereals have vitamins but I must read the label. I know not everything that says whole grain is healthy. In fact some sweetened cereals are healthier than some organic food cereals due to low vitamin and high calorie content.
5. Chickens are grain fed and they are a small lean meat. Cows by body shape are naturally supposed to be big. It’s not that cows are fed grains they are over fed grains and grass to get fatter faster. Bison though leaner and grass fed are still a big animal.

1. Some Grains lower cholesterol.
(But What about the overload on the bad Omega 6 fatty acids? Grains contain phytic acids which interfere with nutrient absorbtion. I have new studies that the amount of cholesterol has NO direct relation to atherosclerosis. Some studies may show that grains may lower cholesterol, but may raise Lp(2), which is the TRUE reason of atherosclerosis.)

2. Fruits even organic are simple carbs and would elevate ones insulin levels more than a bowl of oatmeal.
(Fruits contain much more fiber than oats. Organic apples contain far more antioxients than nonoganic apples. Furthermore, oats contain acids that can deplete your omega 3 fatty acids, causing an imbalance of fats, which is the underlying cause of atherosclerosis.)

3. Any diet that works deals with calories. Your diet is lower calories than the one you’ve been on so you lose weight. Low carb diets have been studied and the ones that work are low calorie diets. When you remove a food group you cut calories.
(NOT True. Trans fats and refined carbohydrates causes excessive triglycerides in the liver, which causes the liver to store fat. Therefore, a fatty liver may be partly the result of storing fat. A diet rich in trans fats and excessive refined carbohydreates are the true underlying cause of obesity. Americans today are eating french fries, fried meats, bread, doughnuts, pizza, pasta, cereal (even whole grain cereals), and pasteries. These foods have trans fats and carbohydrates as well as an overload of omega 6 fatty acids, which is the true cause of heart disease in America. They say that a calorie is a calorie is a calorie is wrong. You need to balance your calorie intake and you also need to get a metabolic test done. You may not be following your diet that's intended to what your genes tell you.)

4. I lost a lot of weight eating whole grains. Grains are not the devil for all people. Oatmeal has fiber and is filling. Cereals have vitamins but I must read the label. I know not everything that says whole grain is healthy. In fact some sweetened cereals are healthier than some organic food cereals due to low vitamin and high calorie content.
(It's more than weight. What about your meat-to-fat ratio on your body? That's a greater risk factor towards health problems than weight. You can be 5 feet 8, weigh 245 pounds, but have a ton of meat but not a whole lot of fat. Low carbohydrate dieters who are protein type tend to have more muscle mass than high carb, low fat dieters. In other words, YOU MAY BE LOSING WEIGHT IN AN UNHEALTHY WAY!)

5. Chickens are grain fed and they are a small lean meat. Cows by body shape are naturally supposed to be big. It’s not that cows are fed grains they are over fed grains and grass to get fatter faster. Bison though leaner and grass fed are still a big animal.
(You are misinterperting this. Grains itself will marble up the cow with unhealthy fats, lose the muscle, and deplete omega 3 fatty acids and greatly raise omega 6 fatty acids, worsening our balance of the polyunsaturate intake. Furthermore, bison is big, and yet musculer. They have very little fat in it, because naturally, bison does not eat grains and they eat grass. Furthermore, grass is rich in omega 3 fatty acids while grains is rich in omega 6 fatty acids. A result is: a meat that has no omega 3s, lots of omega 6s, and the imbalanced ratio of omega fatty acids is the true underlying causes of inflamed arteries.)

In relation to article.

I wonder if this will make people think?

Or will they switch off their mind as usual?

There can only be so much scientific proof before people will have to abandon belief systems and follow empirical and clinical proof.

I know my low carb diet that, I have lost 120 pounds (55 kilos) on, is maintainable for life. I have not had a single hunger pang in 9 months.

The key to maintenance is the controlling of blood sugar and hunger.

Oh, I'm SO OVER with this grain + omega 6 fatty acids + bison thing. Let's all take our Omega 3 -supplement and make someone's day.

And the last time I checked, the new americans (former europeans) killed all the bisons in 100 years. I doubt the surviving bisons' gene pool is wide and perfect these days. There are no bisons in Europe, either. However, we do not allow the antibiotic-saturated meat to be imported from USA (which is why USA has sued the European Union). If all the americans begun to eat bison, there would not be enough grass in this world. And because the prices would have to go down this would mean horrible living conditions for this wonderful animal.

And these trans fats we constantly keep being reminded of... People, stop eating trans fats.

So James, you are saying that you can only be very lean by eliminating grains from your diet?
I will have to disagree with you a bit here. I follow a diet low in refined carbs. I eat a lot of fresh fruits, vegetables, poultry, fish (especially salmon and tuna), and whole grains like oatmeal and whole grain bread. I also eat nonfat dairy products (skim milk and plain nonfat yogurt). I have 10% body fat. Know why? I run about 6 miles a day and my body is conditioned to store energy as glycogen, not fat. Diets low in carbs usually cause weight loss because you can't have sugar on them. Therefore, people who do low carb don't drink regular soda, don't eat candy/chips/white bread/ice cream/etc. So they are indeed reducing their calories. Personally, I couldn't do a very low carb diet because of how active I am. Plus, I need carbs or I'd be so crabby it wouldn't be funny. I also think I'd go nuts wondering how many slices of tomatoes I could eat because OH DEAR, tomatoes have CARBS! I personally don't know anyone who ever gained weight eating too many tomatoes.

We also ate whole grains in the 1900. People have heart dieses because of a sedentarily lifestyle. People are eating too much and not moving enough. You can be thin and eat crap. You can be thin and unhealthy.

I am not saying your diet won’t work but it won’t work for everyone. I am glad you found something that works for you. James you should really start your own blog. Even though I think you’re wrong I do think you have a right to say it.

1. Yes some grains do lower it but by a small%. Some people went overboard with oatbrand. You can over due anything.

2. Iam not talking about antioxients but the fact you state oatmeal spikes your blood sugar well fruit does it more.
It’s better to eat a verity of foods even if you did low carb. Some foods have things other foods do not. I am not saying don't eat fruit. I love fresh apples. I eat a lot of apples.

3. Yes it’s true medical studies prove over and over again that low carbohydrate diets work because they are low calorie diets. Proteins are filling and if you cut out a food group you cut calories out. This is why people can lose weight if they are doing Atkins or become vegans.

4. Maybe I should have stated I lost a lot of fat eating oatmeal. I’ve been informed I need to increase my over all body fat oatmeal did not cause excesses body fat on me. I am a woman I need more body fat than a man or health problems can exist. Body fat isn't all bad.
Body building trainers with very lean fat ratio mix their carbs with proteins all the time. Some trainers it will be the only way they eat carbs. T

5. But then why doesn’t grains marble up chickens in unhealthy fat?

lowcarb_dave, while I have no opinion on the effective ness of low carb diets (I'm losing my weight by following Weight Watchers, and it works for me, so I haven't tried low carb), I do disagree with this statement:

"There can only be so much scientific proof before people will have to abandon belief systems and follow empirical and clinical proof."

As we've seen with both the evolution/intelligent design debate and the debate over whether homosexuality is genetic or a choice, empirical and clinical proof mean nothing to people with hard core beliefs. They will believe what they want no matter what proof you throw at them. As you said, they'll sadly, "switch their minds off as usual".

Jen,

I agree with you. I'm not very optimistic.

In relation to Weight Watchers. I am a veteran of WW. I lost over 30 kilos and ran a few meetings, and worked as a recorder for 2 years.

Believe me when I say this, it worked for me, for a time, but not in the long run. I witnessed first hand at the meetings, the very poor long term success rate.

That's good for WW though, lot's of repeat business. I have re-joined over 20 times.

I have invested a lot of money and my time into trying to make the Weight Watchers system work.

What I am saying is, I tried the route of blaming myself for my weight condition. I did that for many years. It wasn't until I looked at the quality of my diet and went on the Atkins Diet, did I find the real solution.

James, I feel just as you do!! I'm lucky enough to live on a ranch. Our eggs are farm fresh and the cattle we raise are old fashioned grass fed...The highly processed garbage were feeding our families today plus the lack of exorcise, i.e.. t.v, computers and video games....all contribute to our health..
