Lose Weight - Grab A Glass

---------------------------------------- In childhood, we heard it: Drink a glass of milk at every meal. Now TV commercials are toutingrepparttar 138860 weight-loss effects of milk and other dairy products. Can dairy actually keep weight under control? How is that even possible?

Michael Zemel, PhD, director ofrepparttar 138861 Nutrition Institute at repparttar 138862 University of Tennessee at Knoxville, has published numerous papers on this subject. He outlines his latest research inrepparttar 138863 January 2003 Journal of Nutrition, mouse studies showingrepparttar 138864 role of calcium in weight gain and fat storage.

Too many people drop dairy from their diets when they try to lose weight, he says. "They're shooting themselves inrepparttar 138865 foot when they do that. Dairy products contain literally hundreds of compounds that all have a positive effect on human health and enhancerepparttar 138866 fat-burning machinery," he explains.

Milk The Why & How

---------------------------------------- "When we cut dairy products, we sendrepparttar 138867 body a signal, to make more fat," says Zemel. "When your body is deprived of calcium, it begins conserving calcium. That mechanism prompts your body to produce higher levels of a hormone called calcitriol, and that triggers an increased production of fat cells."

High levels of calcitriol "tell" fat cells to store themselves inrepparttar 138868 body, he says. This increase in calcitriol also "tells" fat cells to expand, he says. "So you're getting bigger, fatter fat cells. And a lot of big, fat cells makes for a big, fat person."

Extra calcium in your diet suppresses this hormone, he says. Your body breaks down more fat, and fat cells become leaner, trimmer. A high-dairy diet can boost weight loss by about 70%.

But wait, there's more. "It turns out that milk, cheese, and yogurt are much more effective than calcium supplements or calcium-fortified foods," Zemel says. Why? Dairy products are a complex collection of compounds. Like phytochemicals found in fruits and vegetables, there's more than vitamins and minerals in dairy products. "They are not classically nutrients, but are recognized as having beneficial effects."

Fat Calories Still Count, But Calcium Will Change Your Body Composition

----------------------------------------- Dairy isn't a weight-loss miracle, says Zemel. Calories still count. But even if you don't restrict calories, taking in more calcium will change your body composition. You're shifting calories from fat to lean body mass. "Onrepparttar 138869 scales, you may not see a change. But we've seen a loss of body fat," he says.

"We need to think of milk as more than a calcium-delivery vehicle," he says. "It's more than just calcium. It's high-quality protein, a collection of amino acids that provides positive effects on skeleton, muscle, and fat."

Zemel's research holds water, says Lara Hassan, MS, a nutritionist withrepparttar 138870 Cooper Clinic in Dallas. Indeed, "studies are showing that high calcium increases fat oxidation or fat burning, and that results in greater fat loss, and weight loss if it's a reduced-calorie diet.".

She cites one study in which obese men consumed two cups of low-fat yogurt a day, and made no other changes in their diet. They lost an average of 11 pounds overrepparttar 138871 course of a year.

Water Heavy Foods Tell Your Brain You're Full


Tomato juice, tomato soup, vegetable soup, water-heavy foods like these seem to trigger receptors inrepparttar 138872 stomach that tellrepparttar 138873 brain you're sufficiently fed, says Barbara Rolls, PhD, a professor at Pennsylvania State University and author of The Volumetrics Weight-Control Plan: Feel Full on Fewer Calories.

LASIK - A now common procedure

One ofrepparttar first things that springs to mind when considering corrective eye surgery isrepparttar 138676 term, "LASIK". An acronym for "laser-assisted in-situ keratomileusis," this rather common procedure is used to correct certain vision problems through refractive surgery.

Since its debut inrepparttar 138677 1980s, there have been conflicting stories about what LASIK entails and whether or not it's truly successful.

Laser eye surgery is typically used for those who suffer from nearsightedness, farsightedness or astigmatism. Untilrepparttar 138678 advent of LASIK, eyeglasses and contacts were used to treat these issues, but only served as aids to vision rather than corrections.

Those who have undergone a successful laser eye surgery procedure should find that their need for such aids are extremely diminished or eliminated altogether.

Reshaping your eyes

Technically speaking, LASIK eye surgery reshapesrepparttar 138679 cornea from withinrepparttar 138680 eye itself using laser to accomplishrepparttar 138681 task.

If, for instance, your cornea is not shaped correctly to fitrepparttar 138682 dimensions of your eye, this procedure may be effective. By utilizing laser to extract bits of tissue fromrepparttar 138683 cornea in order to reshape it,repparttar 138684 refractive error can be corrected andrepparttar 138685 visual images will then be focused directly ontorepparttar 138686 retina, which may eliminaterepparttar 138687 need for aids such as eyeglasses and contact lenses.

After a thorough eye examination, you'll be expected to choose a doctor to performrepparttar 138688 LASIK eye surgery. Once this has been done, you'll be scheduled for a consultation withrepparttar 138689 doctor to discussrepparttar 138690 process, and you'll haverepparttar 138691 opportunity to voice whatever questions or concerns that you may have prior torepparttar 138692 procedure.

You should expect to be instructed not to wear your glasses or contact lenses for two to four weeks prior to your surgery, in order forrepparttar 138694 cornea to return to its natural shape, without interference from external visual aids.
