CRAVINGS!
We all seem to get them, don't we? It seems like your appetite just throws a
tantrum and demands more food. Against all reason, the cravings may even hit right
after a large steak dinner. Or right out of nowhere. Is there any rhyme or reason
to these cravings?
Scientists say yes. They've discovered that our appetites do indeed follow some
underlying rules. Appetite, they say, is turned on both by what's happening outside
of us--like whether someone's just offered us a doughnut--and what's happening inside
our bodies--the biochemical signals between mouth, stomach, nervous system and brain.
In one of the hottest new areas of research, scientists are discovering that certain
foods may even trigger the desire to eat more, while other foods tend to suppress
that desire.
New research points to at least 10 different ways you can control the urge to
eat, whenever or wherever it strikes you.
- Drown your appetite. "Drinking generous amounts of water is overwhelmingly
the number-one way to reduce appetite," says Dr. George Blackburn, associate
professor at Harvard Medical School. Reason: A lot of water takes up a lot of
room in the stomach. The stomach feels full, reducing the desire to eat. Water
can quell the appetite in other ways. "Many people think they're having a food
craving, when in fact they're thirsty, "says Dr. Blackburn. So next time you
get the urge to eat, try a cup of water instead. Aim for 64 ounces of fluids
daily. Don't gulp down an entire glass at a time, as if it were medicine, or
you'll never continue. Instead, sip 3 to 4 ounces at a time, throughout the
day.
- Graze sensibly. Mom always warned us not to snack before mealtime, to avoid
ruining our appetite. But nowadays, scientists are rethinking Mom's advice.
Grazing means nibbling small amounts of food frequently, instead of eating just
one to three large meals a day. Scientists who endorse it say grazing can keep
your appetite down all day long and prevent bingeing. Nutrition specialists
believe that grazing quashes the appetite because it keeps insulin levels steadier--and
lower--than eating a few large meals. A large meal, especially one that's sugary
and high in fat content, stimulates the body to produce lots of insulin. Its
job: to remove all of those excess sugars and block the release of fats into
the bloodstream. Smaller, more frequent meals, on the other hand, keep insulin
and blood-sugar levels more stable, so the brain doesn't signal an urgent need
for more fuel. But for grazing to be effective you have to munch the right kinds
of foods: You cannot graze on M&M's, potato chips and Haagen Dazs. Your insulin
levels and appetite increase. But if you graze on low-fat, high-fiber foods
that aren't packed with calories--like carrots, peaches, oranges, red peppers,
pasta, potatoes, oatmeal--you keep your appetite down.
- Soup it up. A lot of research over the years suggests that soup has the
ability to turn off the appetite with far fewer calories than many other foods.
In a study at Johns Hopkins University, researchers compared soup with other
appetizers to see which most effectively dimmed the desire to eat. They invited
12 men to lunch for two weeks. On different days, the men received different
appetizers of tomato soup, Muenster cheese on crackers, or fresh fruit. Calories
in each appetizer portion were equal. Then the men were given a main course
to eat. Results: Tomato soup was the most satisfying appetizer. It beat out
all the others in reducing the number of calories of the entree that were consumed.
The least satisfying appetizer: cheese and crackers. Soup reduced later calorie
intake by 25 percent compared with cheese and crackers.
- Eat more complex carbohydrates. A few years ago, potatoes and pasta were
forbidden foods among dieters. We were encouraged to dine on a hamburger (without
the roll), with a side order of cottage cheese (nestled on a lettuce leaf).
Since then, high-protein, low-carbohydrate schemes have been debunked as unhealthy,
ineffective in the long run and even potentially dangerous. Foods like rice,
potatoes, corn and pasta that are high in complex carbohydrates and low in fat
have made a big comeback. Among their many virtues for weight watchers is their
powerful ability to satisfy the appetite with fewer calories. High-fat foods
don't switch off the "eat" message as effectively as foods that are high in
carbohydrates. For example, take one ounce of potato chips versus a whole baked
potato. Each has 160 calories, but which is more likely to fill you up? Obviously,
you end up eating a lot more calories from potato chips (betcha can't eat just
one!), loaded with fat, than form a baked spud (whose calories come primarily
from carbohydrates) before you feel satisfied.
There's yet another theory about why carbohydrates dim the appetite. It has
to do with the connection between carbohydrates and the brain chemical serotonin.
Serotonin is a mood enhancer, and a lack of serotonin is linked with depression.
The fact that many depressed people are also overweight has led some scientists
to investigate the possibility that lack of serotonin stimulates food cravings,
while boosting serotonin levels reduces appetite. They've discovered that carbohydrates
seem to increase brain levels of serotonin--and reduce appetite. But this research
is still in the early stages.
- Say SI! to spicy foods. Have you ever binged on a huge plate of spicy food--like
Mexican, Thai, Szechwan or Indian fare? It's nearly impossible. Those foods
seem to quiet the appetite better than blander fare. One possible reason: The
flavor is so intense that we don't need as much. Spicy foods also speed the
metabolism. When people eat hot chili, they often sweat, a sure sign of increased
metabolic rate. And the faster the metabolic rate, the more heat produced by
the body. Remember, whatever warms you up, in turn slims you down. (Roger's
Buffalo Wings will do this in an excellent manner! So stock up on hot peppers,
horseradish, chili powder and the like. Learn to use them often, especially
in place of salt. Salt does make some people eat more, perhaps by upping insulin
levels, but the best reason to avoid salt is because its use often leads to
high blood pressure.
- Feast on fiber. How does fiber satisfy? In many ways. Satisfaction begins
in the mouth, and fibrous foods provide robust mouthfuls that must be chewed
thoroughly. It's a natural way to slow down eating, and eating slower means
eating less--the extra time lets the body know it's received fuel and doesn't
need much more. Next, fiber takes up a lot of room in the stomach, and increased
stomach volume reduces appetite. So the stomach feels full longer. Soluble fiber,
best known for its cholesterol-cutting abilities, also dampens insulin response.
Normally, after a meal, insulin levels rise to help metabolize sugar and fat.
But soluble fiber keeps insulin levels lower after a meal.
Richest sources
of soluble fiber include barley, oat products, beans, apples, citrus fruits
and root vegetables like beets, carrots and potatoes.
Finally, foods that are high in fiber tend to have fewer calories in every
bite, which means fewer calories consumed overall. Research at the University
of Alabama shows that people eat many fewer calories on a low-calorie-density
diet than a high one.
- Eat simply. Your mother has invited you to dinner and she's eager to please.
There's freshly baked bread, a shrimp appetizer, a roast beef entree, a potato
side dish, rice pilaf, noodles, fresh corn, broccoli, and raspberry pie, chocolate
truffles and frozen yogurt. If you're like most mortals, you'll want to try
a little of everything. Unfortunately, by the end of the meal, that may translate
into a lot of food. Now imagine this: Instead of the multi-course feast, she
serves a simple dinner of salad, a one-pot chicken-and-rice casserole, with
raspberry pie. How likely is it that you'll overeat? Much less. Serving a wide
variety of foods at one meal can cause you to eat much more. That's because
each different food has its own satiety level. So after you've had as much shrimp
as you want, you might still crave the roast beef. After the bread, you'll still
want to try the potatoes, noodles and rice. And of course, it's nearly impossible
to resist "just a taste" of every dessert. So limit entrees and side dishes
to one each at every meal. And look for some one-pot meals that your family
can enjoy.
- Outbike your appetite. Got the munchies? If you've already tried a glass
of water or a high-carbohydrate, high-fiber snack, but they didn't do the trick,
take a walk, ride an exercise bike, or do some other activity. Regular exercise
reduces the appetite, in part by modifying the insulin response, which reduces
the upward spike that has been associated with increased appetite. Exercise
helps control blood sugar, leading to a steady state associated with fullness.
Aerobic exercise reduces the appetite in the short run, perhaps because it heats
the body. Not many people can eat a lot after exercise. In the long run, a regular
exercise program increases appetite somewhat. That's because you burn up your
glycogen stores more quickly. This partially offsets the appetite-dimming effects
of the temperature rise. But when you step up exercise, you usually don't eat
quite enough calories to make up for the amount of fat you've burned off. Provided
you're on a high-carbohydrate diet, you can replenish your glycogen stores without
replacing the fat you burned off exercising.
- Ask yourself 'why?' Before you eat, ask yourself why you want to eat. It
may help you realize that it has nothing to do with hunger. Emotions are a major
reason people eat. Some physician report that 85% or their patients have psychological
reasons for overeating. One of the major reasons is stress. Stress makes you
eat more quickly than anything else. Some people who are stressed out go for
soft, creamy, comfort foods, like mashed potatoes with plenty of butter. Or
they want baked foods, like a milk-and-cookies snack: It's the "nothing-says-loving-like-something-from-the-oven"
syndrome.If you are turning to food in response to bad feelings, it's important
to develop a strategy to feel better. Before you eat, ask yourself, 'How am
I feeling about myself right now? What's happened this week to upset me? Am
I eating this because I'm hungry or because I'm upset?'
- Know your own triggers. The sound and smell of sizzling sausage. The crunchy
texture of popcorn. The sound of a can of Spam(tm) being popped open. The smell,
sight, sound and even texture of foods are the most powerful triggers we have
to eat--and to overeat. Sometimes we eat things because they look good, even
when they aren't. Haven't we all eaten mediocre cookies, just because they looked
delicious? And sometimes we eat them just because they're around. So eliminate
the temptation by banishing fattening foods from the house. Our eating is so
dependent on external cues that just seeing foods makes us want to eat. If someone
else in the family has to have sweets or high-fat foods, ask him to hide them
somewhere that you can't find them. Keeping a food record can help you identify
these kinds of cues. For a couple of days, write down everything you eat and
try to recall what made you start thinking about food--whether it was an advertisement
or an emotion or an aroma. That helps you out-think a craving next time it happens.
