Hello CR ALL:

Thank you E Selpaolini -- for this Wall Street Journal article.

I have reformatted it, and also sorted the columns in the

food chart in energy density rank. The title says it all.

Title: Dieter's Dream: How to Eat More and Still Lose Weight

-------------------------------------------------------------

When it comes to dieting, bigger food is better.

That may be surprising to dieters who've struggled to cut calories by

eating less food. But a growing body of research now supports the

notion that it's the energy density of foods -- not the amount we eat

or even the overall fat content -- that most contributes to weight

gain.

A food has a low energy density if it has few calories relative to its

weight. An easy way to choose these low-energy-dense foods is to choose

" big " foods -- those that are bulked up by fiber and water. Chicken and

rice soup, for instance, has a low energy density, with just 0.5

calorie per gram. And it will be just as filling and less fattening as

a similar amount of cheese ravioli, which has 3.2 calories per gram.

Food labels don't tell you about energy density, so you have to do the

math yourself to calculate calories per gram. Foods that have up to 1.5

calories per gram are low energy dense. Foods with 1.5 to four calories

per gram are considered medium, while high-energy-dense foods have four

or more.

It might seem obvious that low-energy-dense foods such as chicken soup

are less fattening than the same amount of, say, potatoes au gratin.

But there are some surprises. Even a decadent-sounding cream of

broccoli soup with cheese has an energy density of just 0.8. But graham

crackers, though low in fat, have a high energy density, with 4.2

calories per gram.

WHEN MORE IS LESS

-----------------

Here's how to lower the energy density of your diet so you can eat more

without increasing your caloric intake.

Switch to soups: Even creamy soups and rich stews have a lower energy

density than many foods.

Add bulk: Adding vegetables to pasta or casseroles or more veggies to a

salad lowers the energy density.

Beat your food: Smoothies and shakes fill you up longer the longer they

are whipped.

Substitute: Switch to low-fat dressings, cheeses and cooking oil in

recipes

• See a list of some low-energy-dense food options below.

And the energy-density idea works with indulgence foods, as well. M & M's

are considered a high-energy-dense food, with 4.9 calories per gram.

But for about the same calories of a package of M & M's, you could have a

slice of chocolate cake with frosting, at just 3.7 calories per gram,

or vanilla pudding made with 2% milk, at just one calorie per gram. And

you'd be left feeling far more satisfied.

The push to focus on the energy density of foods is backed by numerous

studies that show hunger tends to be satisfied by a certain volume of

food, regardless of the calorie content. In one Pennsylvania State

University study, researchers found that healthy women instinctively

ate about three pounds of food a day. It didn't matter if the foods

were high-calorie or low-calorie -- the women were driven by volume,

not calories. Because we are accustomed to a certain volume of food,

when we try to cut back on the amount we eat, we feel hungry -- which

is the main reason diets fail.

All of this runs counter to the notion that people who are overweight

are just eating too much food. Often those people are eating normal

amounts of food for their size -- they are just choosing energy-dense

foods that cause them to continue to gain weight.

To really make an impact on weight, people need to consume far more

" big " foods like fruits, vegetables, salads and soups. That can

include, for instance, adding more vegetables to bulk up casseroles or

other dishes to lower the overall energy density of favorite foods.

Dieters should pay attention to basic nutrition and eat a balanced

diet, but they should also work to ease high-energy-dense foods out of

their diets.

The problem is that our taste buds don't always like low-energy-dense

foods as much as small convenience foods like snack chips and brownies.

But new research shows there are ways to use low-energy-dense foods to

help curb consumption of more fattening foods, without having to give

them up altogether.

In a study presented Monday at the annual meeting of the North American

Association for the Study of Obesity, Penn State researchers studied

how eating salad before a meal could affect total calories a diner ends

up consuming.

GOOD EATS

---------

• Study Says Ranks of the Very Obese Widen Sharply

• Americans Are Starting to Shape Up, Eat Healthier

Diners were allowed to eat as much regular cheese tortellini as they

wanted. One group was just given the tortellini, while other groups

were told they had to eat a serving of salad first. The salads included

both high-calorie and low-calorie dressings and cheeses, and the size

varied from a 11/2 cup to three cups.

Researchers found that when diners pigged out on three cups of salad

with low-fat dressing, they ate 107 calories less -- or about 12% fewer

calories for the meal than when they didn't eat a first-course salad.

The finding was surprising because studies have shown that first

courses tend to make people consume more calories, not less, because

variety can excite the appetite, which is why we forget we're full when

a tantalizing dessert arrives on the table.

In the case of the salad study, the first course had such low energy

density that it translated into fewer calories, despite the variety

effect. But be warned, the energy density of the salad matters as well.

Some diners were given a more energy-dense salad with full-fat dressing

and cheese. They ended up eating 145 calories more -- or about 17% more

calories for the whole meal -- than those who ate no salad at all.

" People aren't that sensitive to calories when they're eating --

they're more sensitive to volume, " says Penn State nutrition researcher

Barbara Rolls, who has led many of the energy-density studies. " After

eating the salads, if they had a lot of [the low-calorie one], it

helped them to eat less. But if the salad had a lot of calories, they

didn't compensate by reducing their intake during the rest of the

meal. "

The lesson for dieters is to binge on a healthy salad or other very

low-energy-dense foods before a meal. It's worth noting that dieters in

the study rated the salads equally satisfying, and didn't notice the

difference between the full-fat dressings and cheeses and the lower-fat

options. But if you want to indulge in full-fat dressing, you still

can, as long as you further lower the energy density by adding a lot

more vegetables.
