Atkins diet disappoints in long-term weight loss

High-protien and high-fat plan can hurt kidneys, weaken bones

If you're one of the many college students trying to shed a few pounds, you might be thinking about going on a diet.

Maybe you're fighting the freshman 15 or you just want to turn a few heads at Venice Beach. Whatever your reason, you've probably heard of the Atkins diet – the low-carbohydrate, high-protein and high-fat diet created by cardiologist Robert Atkins 30 years ago.

The regimen instructs dieters to throw the low-fat adages out with all their breads and pastas, and encourages people to eat as much bacon and eggs as they wish.

During the first two weeks dieters eat no more than 20g of carbs – equivalent to a single slice of bread or a serving of corn. Later, the carb level is increased slightly until weight loss stops. There are no limits on protein or fat.

Surprisingly, recent studies show that the Atkins diet works – at least for a while. Although participants eat high-fat meals, they actually lose weight more quickly on the Atkins diet than on a low-fat diet.

But is it really possible to eat fatty foods and be thinner?

In April, the Journal of the American Medical Association looked at all the studies available and found people lost weight on the diet because they ate fewer calories altogether even though more of their calories came from fat. Protein is more filling than carbohydrates, which probably helps people on the Atkins diet feel less hungry.

But before you rush out for 4x4 cheeseburgers at In-N-Out, you should know there are some definite drawbacks. Eating less fruit and whole grains means missing out on cancer-fighting benefits of anti-oxidants and fiber.

Eating lots of protein can decrease the amount of calcium in your bones, increasing your risk for osteoporosis later in life. Calcium loss is even more of a concern while you're in college because you gain most of your bone mass before you reach 30. Increased levels of fat and protein are also linked to kidney stones and kidney problems. Other minor problems include constipation and bad breath.

Physicians are most concerned about the high amount of saturated fat in the diet. Saturated fat, which is especially high in red meat and dairy products, contributes to heart attacks and other heart diseases. However, a study in the May New England Journal of Medicine shows the effects of the diet on the heart may not be so bad.

Even though more of their calories come from fat, Atkins dieters eat slightly less fat overall than they do regularly, and cholesterol levels actually improved more in individuals on the Atkins diet than in those on a traditional low-fat regimen.

If you want to try a low-carb diet, a healthier version may involve getting most of protein from chicken, fish, and nuts, which contain less saturated fat. Keep in mind, though, that the Atkins diet, like all diets, is not great at helping you lose weight or stay healthy in the long-term.

After one year, the New England Journal study found the average amount of weight loss on the Atkins diet was small, only about 4.5 percent after a year. By then, four out of 10 of those on the Atkins diet had dropped it, and those still on the low-carb diet actually gained back about half the weight they lost.

Diets are short-term and, unfortunately, so is the weight loss associated with them. The best way to really make a long-term impact on your health is to incorporate small changes in diet along with an exercise plan that you're comfortable with.

Some statements just make no sense.

"Even though more of their calories come from fat, Atkins dieters eat slightly less fat overall than they do regularly"

Does this mean that Atkins dieters eat fat that has less calories than they did before? What is this magic fat?

In April, the Journal of the American Medical Association looked at all the studies available and found people lost weight on the diet because they ate fewer calories altogether even though more of their calories came from fat.


Hmm- I think someone needs to do a little more research. In my mind, and on my calculator, the 1700+ calories I'm consuming now while losing weight is a LARGER amount than the 1000 to 1100 I consumed on WW and GAINED weight. Am I doing something wrong with my calculations?

Seriously, where do these people get all of this misinformation? Are they all just making this stuff up out of thin air?

And this, from a med student. Scary that she'll be making life or death decisions some day.

Students believe what they are told. Here's what we are all told:

Saturated fat leads to heart attacks, stroke, and cancer.
Complex carbohydrates shoudl be the basis of your diet.
Only fat makes you fat.

And it's all wrong!
Unfortunately, all kinds of misinformation gets perpetuated, like the "lots of protein bad for your kidneys" thing that studies show does NOT happen.

A first year med student. At this point she's probably not even STARTED with metabolism or anything more complex than basic physics and biology... Hopefully she'll learn that an open mind is one of the most important things a medical professional can have!

My goodness......they should see how much I eat! I'm so incredibly tired of those worn off argumentations.
Why is it so hard to accept this WOE agrees with many people and actually makes them healthier, happier, thinner?

*sigh*
