But apples? Mango? Strawberries?
You mean, I can eat my favourite fruit all day, amd not feel guilty. I'm so glad I found this forum.
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
