how to lose weight

Drink Mainly Water

A sports or energy drink, fruit smoothie, or light beer — each serving contains about 100 calories. Yet these beverages don't satisfy you the way 100 calories of food does, so they're a waste. Other liquids may be high in sodium and carbohydrates, which trick your body into retaining water, puffing you out.

Water, on the other hand, has zero calories and carbs and little to no sodium, making it the perfect slim-down drink. And strangely, it actually helps flush out excess water weight as well as jump-starts your metabolism. If it's just too boring, add lemon wedges or mint leaves.

Ban White Bread and Pasta

Cutting out all white grain products — such as white rice, spaghetti, sandwich rolls — will instantly slim you down because the simple carbs in these foods cause bloating, especially around your belly. "Simple carbohydrates wreak havoc on your weight because they're digested very quickly, leaving you hungry and more likely to overeat later," says Jana Klauer, MD, author of The Park Avenue Nutritionist's Plan.

To go a step further, instead of replacing them with healthier yet still bloat-triggering whole-grain bread products, substitute vegetables for the week. This way, a chicken sandwich becomes chicken salad, and chips and dip turn into carrots and dip. The complex carbs from vegetables are digested more slowly, so you remain full longer. And because veggies are mostly water, they also help flush out excess water weight.

Drink Coffee an Hour Before Working Out

This is the one exception to the stick-to-water-only rule: Just as a coffee run makes your morning at work more productive, a pre-exercise cup of java with a splash of skim milk (about 11 calories) or black (just 5 calories) will energize your workout, explains Dr. Klauer. "You'll burn more calories without realizing you're pushing yourself harder."

Have Nightly You-on-Top Sex

Not that you needed an excuse to hook up with your guy every night, but the fact is, this position is a fat blaster. Being on top means you do the rocking, and the more active you are, the more calories you burn — up to 144 for 30 minutes.

Sex also pumps levels of feel-good neurotransmitters, endorphins, helping you ride out food cravings. Get on top in reverse-cowgirl (i.e., facing away from your guy) to give your thigh and butt muscles an extra push.

Make One Food Sacrifice

Cutting out one indulgence — such as the chips you have with lunch or the chocolate dessert you eat after dinner — can subtract a few hundred calories from your diet, which translates into less flab, says Blum. "Your body won't even notice their absence."

Stand Up Straight

Keeping your spine rigid and your shoulders back while sucking in your belly toward your spine gives you a slimmer, more streamlined middle.
