I don't think thats how it works....but do your own reseach
I found this on the internet.....
2. Certain foods, like grapefruit, celery, or cabbage soup can burn
fat
and make you lose weight.
NO. Based on anecdotal stories, this belief has no scientific back up.
It’s true these foods are low in
calories (and loaded with nutrients),
but they do not actually burn
fat.
Rumors have also circulated claiming the act of chewing certain foods burns
up more
calories than the food contains. Cucumbers and celery top the list of
these so-called “negative calorie” foods. While it may seem like you expend a lot of
energy when you chew some things, in reality, it’s only about five measly
calories per hour.
BOTTOM LINE: If you lose weight when you add grapefruit, celery or cucumbers to your
eating plan, it’s probably because you’re substituting these foods for another food
that has more
calories. For example, instead of snacking on pretzels
(130
calories per ounce), substitute with celery sticks and cucumber slices
(14
calories per cup).
and this.....
The theory goes like this: Your
body burns some of the
calories in your food to run
the chemical and mechanical processes that digest the food. But some foods
contain fewer
calories than are needed to digest them -- so by eating such foods,
you actually lose weight. Say, for example, you're eating a 1 1/2-ounce stalk of celery.
It contains 7
calories, but maybe your
body needs 30
calories to break it down.
If that's true, eating a stalk will burn off 23
calories -- and if you eat five stalks a day,
you'll lose a
pound a month. (A
pound of
body weight is equivalent to 3500
calories.)
Other foods that supposedly subtract more
calories than they add include asparagus, lettuce,
broccoli, beets, onions, cabbage, carrots, cucumber, zucchini, apples, oranges, pineapple,
grapefruit, raspberries, pineapple, strawberries, lemon, chocolate truffles, and potato chips. (Sorry, just kidding about those last two.)
You can find plenty of information about negative-calorie foods online.
Most of it is in the form of advertisements for an e-book called The Negative Calorie
Diet. Here's how one ad describes the science behind the
diet:
The process starts by chewing. Then your esophagus moves everything down to your stomach.
This usually takes anywhere from a few minutes to a half hour. For about four hours,
your stomach mixes the food up with acid and sends everything down to your small intestine. For approximately another four hours, your small intestine receives very strong alkaline (digestive) juices from your gallbladder and pancreas. These digestive juices mix with the now liquefied food and your
body starts to absorb it. This process continues on down to your large intestine where the rest of any food and fluids are absorbed into your
body. This may take up to 12 hours! Any residue that is left over is eventually eliminated, but here's the GOOD NEWS! This entire process BURNS
CALORIES and results in
weight loss!
The e-book, according to the ad, identifies over 100 negative-calorie foods that
safely force your
body to work harder during digestion, thus turning your
body into
a "fat-burning machine." Moreover, it "reveals the secrets of consuming negative-calorie
foods" so you can lose 14
pounds in seven days. It promises you can shed weight
"three times faster than FASTING itself!"
(But first, of course, you have to shed $19.95 to download the book.)
Barbara Rolls, Ph.D., professor of nutritional sciences at Pennsylvania State University,
finds the theory of negative-calorie foods "interesting, but very hypothetical.
I don’t think we have the metabolic tools to determine whether this is possible."
Rolls thinks people lose weight eating so-called negative-calorie foods not because
the foods burn
calories, but because they displace higher-calorie foods.
Co-author of the book Volumetrics: Feel Full on Fewer
Calories, Rolls says that
"clinical trials show that eating high-water-content fruits and vegetables helps with
weight management."
In recent studies, Rolls and other researchers found that people who were given a large,
low-calorie salad as a first course ate fewer
calories in their entire meal.
Before serving them pasta, the researchers gave 33 women a 100-calorie salad of lettuce,
tomatoes, celery, carrots, and cucumbers (most of which are considered negative-calorie foods),
fat-free dressing, and light mozzarella. The researchers found that the women ate 12 percent fewer
calories in their entire meal than when they started without a salad. In contrast, when they ate a small, high-calorie salad (200
calories), they ended up consuming 8 percent more
calories overall; and when they started with a 400-calorie salad, they ate 17 percent more overall.
"You eat fewer
calories through satiety," Rolls explains, "not through the metabolic effect."
Very low-calorie foods are good to eat, says Coulston, an authority on carbohydrate and
fat
metabolism, "but you shouldn’t get mathematical about it. Eating is not just the science of
calories and nutrients. It also deals with behavior.
The act of eating stimulates eating other foods as well.
If you’re eating celery, you’ll put a spread on the celery.
You open the fridge and look for other things to munch on.{I am guilty of that one
