Carbohydrates For Weight Loss?

Posted: 05/19/11 02:44 PM ET

One trivial but still agonizing stress of the season is going into a dressing room with three-way mirrors and a handful of bathing suits. Moans, gasps and little wails reverberate off the walls as customers take the first real look at their bodies since Christmas. I've heard all the following comments:

"What happened to my waist?" "Were my hips that big last year?" "Maybe I should just buy a see-through cover-up and stay under a big umbrella."

Although it is tempting to vacation in the southern hemisphere (where it will be winter in August), given the cost of everything these days, most of us will spend our holidays on the shores of a nearby lake or beach. And unless the weather proves as disastrous as it was this past winter, there should be a few days when putting on a bathing suit and lying on a blanket or beach chair is irresistible.

Do not despair. Beaches do not require model-perfect bodies unless there is a Sports Illustrated photo shoot going on. But if you have been thinking of losing weight since January 1, the bathing suit might be the catalyst that gets you to do it. Now.

If you do decide to make the commitment to lose weight, why not use your brain to help you?

We all know that weight is lost when less food is eaten than the body needs. The question is, how do we get ourselves to stop putting food in our mouths, even if we know we are eating too many calories to lose weight?

The answer may be carbohydrates. Potatoes, pasta, rice, wheat, corn, barley, beans, quinoa, oats and lentils are part of the answer. These are healthy carbohydrates that are fat-free in their natural state. Eaten by themselves with very little protein allows the brain to make a very important brain chemical: serotonin. Most of us associate serotonin with keeping our mood stable, but serotonin also functions as nature's own appetite suppressant. Simply put, making serotonin makes our appetite go away. And it is our appetite, not just hunger, that causes us to eat more than we need.

Alas, all of the medications used to make serotonin more active, those antidepressants that prolong the mood-regulating function of serotonin, will not take away your appetite. In fact, some of you may be gnashing your teeth over the weight that you gained from taking these meds. It is not known why those drugs make many people eat more, but they do seem to.

Not surprisingly, drug companies have been trying to find a suppressant that will activate the appetite termination function, or satiety, of serotonin. Why wait for the drug companies? You'll want to get into that bathing suit in a couple of weeks!

An English muffin, ¾ of a cup of Cheerios, a handful of new potatoes steamed with some fresh dill or a cup of oatmeal will give you enough carbohydrates to start the process of making new serotonin. Adding butter, sour cream, bacon or any other high-fat ingredient may make the carbohydrate taste better, but remember that the brain has no taste buds. Try thinking of the carb as a diet pill. Diet pills don't come coated with butter or wrapped in bacon, and neither should the carb you are enjoying to stop you from eating too much.

As we recommend in The Serotonin Power Diet, a small, fat-free carbohydrate snack an hour or so before a meal increases serotonin and takes the edge off the appetite. This is why eating a roll or several breadsticks before your main course leaves you feeling less hungry than you were when you ordered your entree.

But carbohydrates come with a warning: If they are processed into ice cream, chocolate, cookies, pizza, piecrust, fried batter or coated, covered and drenched with fat, they will not help make you thin.

Take heart, there is more good news. Carbohydrates will not deceive you into thinking you have lost weight. One of the gratifying features of a low or zero-carbohydrate diet is that as the stored carbohydrates in the body are used up, water is eliminated. The loss of five or six pounds of water makes the needle of the scale drop by 5 or 6 pounds. It is a great feeling to see that weight loss, but it will not be translated into a smaller size bathing suit -- or smaller hips for that matter.

Carbohydrates will do one more positive thing; they will keep you in good humor. It is sort of a value-added feature of this class of food, in that by making new serotonin, you won't feel grumpy and irritable. Your default mood will be feeling calm, so that when you see how bathing suits seem to be priced per inch, you will be more inclined to giggle rather than growl.

Everyone, whole grains are so bad for you, especially wheat products. Complex carbs=BAD. Check out Marks's Daily Apple, there's plenty of evidence provided there to help people understand why even whole grains are simply bad for human health and were not really ever meant to be consumed. There may be a case for some athletes using "good" grains for energy. Libwingoflibwing explained why grains, even wholegrains, are unhealthy and not suited for human consumption. It's pretty basic, if we have to mill it that way in order to consume it, nature probably did not intend for us to eat it in the first place.

Take back the complex carbs=BAD comment. Of course there are good sources of complex carbohydrates(vegetables and good lower glycemic fruits) and maybe a few of the "better" grains, especially for those athletes out there.

This advice will only make people fatter. Placing the emphasis on carbs (she considers potatoes and rice as healthly??) results in blood sugar levels rising, which results in insulin levels rising, which results in waistlines rising.

Teenagers have their youth working for them--their metabolisms are not as insulin-resistant as that of older adults. But, no doubt, the author (and HuffPost in general, what with Ornish on the website's Council Of Elders) wants to push the DASH diet as good for anyone and everyone.

Eating carbohydrates alone may confer all the benefits you suggest for those who are fortunate enough to be able to process such "snacks" without adverse impacts on blood sugar levels. However, these same snacks would be detrimental to anyone who is insulin resistant (as many of us are, even though undiagnosed as such).

For that segment of the population, the use of low glycemic foods that inherently have either a very low glycemic index or a low glycemic load when eaten in moderation are a far better choice.

For diabetics and the insulin-resistant, potatoes, etc. should never be eaten alone, but used only in strict moderation and combined with ample fats and proteins so as to bring down the glycemic impact of the mixed meal.

There are other ways to raise serotonin that are much more fun than eating potatoes.

Thanks, now I don't need to correct this article since you already did! Corn, peas, beets, pineapple, watermelon and cooked carrots are also high glycemic foods. Especially avoid flour products, even if the flour is "whole wheat." It's still been milled until it is so pre-digested that it turns to glucose in your blood faster than table sugar!

Brown rice cakes have a higher glycemic index and higher glycemic load than vanilla wafers.

Good advice! It mirrors my experience, too. The breakdown of complex carbohydrates
produces a slow, even release of glucose - energy for the brain - and produces
sustained energy, even mood and satiety. Also, permanent loss of excess weight.!

Once potatoes are cooked they are no longer complex. Same with carrots, except we can eat raw carrots.

This is horrible advice, based on debunked science.

I'm losing weight that's crept up on me over the years by carefully watching carbs during the week (not so much in vegetable form, but breads, pasta, sweets), and taking up jogging. 15 pounds off effortlessly in 6 weeks, my mood and energy are better than they have been in years, and I still allow myself to have pizza on the weekend.

Upping your carbs to lose weight is exactly the WRONG advice.

Congrats on your weight loss!

Breads, pasta, and sweets that are high in fructose are bad and eliminating them will see a quick decrease in stored fat. Whole grain breads, rice, and pasta are fine in moderation.

My own experience with eliminating fructose in the form of H F C S and added sugar, replacing it with fructose from fruit, eating more vegetables and sticking with lean proteins has resulted in a similar and sustained weight loss.

Barley, beans, quinoa, and lentils are high in protein and can be substituted for animal proteins. Nuts can, as well.

It isn't bad advice, it just could have been made more clear.

Thanks... I tend to eat "better" carbs (vegetable sources, whole grains and wild rice_ in place of overly refined and processed ones, and don't plan on eliminating them. But for the purpose of getting back to where I was a few years ago, I am restricting carbs to

Barley, beans, quinoa, and lentils are only high in protein for a plant source... they are not high in protein. Most the calories in each of those still comes from carbohydrates, and the proteins you do get from them are 'incomplete' (have a poor amino profile), or even worse, are really protein-like (like gluten) and cause problems with the gut and protein synthesis in general.

The author is talking about complex carbs not junk food like bread, pasta and sweets.

Doesn't matter--once you cook grains they're just as insulin-spiking as Coke. And potatoes are especially bad. And besides, people who want that serotonin boost want it FAST, and if they can salve their consciences by saying, "Well, this is whole-grain bread like Doctor Oz says to eat, so it's okay" they'll do it.

If they are eating sweets, processed carbs, HFCS, high fat, high sodium.

I eat a plant based diet that includes fruit, starchy vegetables, greens and whole grains. Due to the quantity of carbohydrates I consume (50% of caloric intake), my diet is considered "high carbohydrate". But my diet is lower in calories, low glycemic, high fiber and very nutritious.

I've noticed it's very common for anti-carb supporters to not mention the difference between bad carbs and good carbs. It's like they consider a donut and a sweet potato as the same evil.

Your diet is lower carb than the USDA food pyramid recommends, which has you at around 70% calories from carbs.

The glycemic index is useless unless you eat carbs alone. It only addresses how fast sugar hits the blood steam, not the quality of the carb (sugar type and nutrient/anti-nutrient makeup of the source). As soon at you eat your carb with protein and fat, it becomes a slow digesting carb.

Your observing that 'anti-carb' people know what they're talking about. There's no such thing as a good carb or bad carb: carbs are anabolic (or they bring about an insulin response which is highly anabolic), and they are a source of high-output fuel for anaerobic activity.

Carbs are 'good' when you're trying to build muscle, or fuel high-intensity physical activity. Carbs are bad when you trying to loose weight, and sedentary/low-output.

It's not good or bad. They are non-essential. It's that they should be used appropriately, and not as a dietary staple.
