Drop 5 Pounds in a Week !

Cosmo has come up with a fat-torching plan that really will subtract up to 5 pounds from your bod in seven days — without starvation, bizarre supplements, or cutting out entire food groups. How? It's all about small sacrifices combined with specific techniques. And rather than giving you a one-size-fits-all regimen, we figure you're more likely to stick with the plan if you pick the eating and exercise strategies that fit your lifestyle.

So choose at least four of the nutritionist- and fitness expert-backed tips that follow, and vow to work them into your schedule for seven days straight. If you feel ambitious, tack on a few more. The more you pick, the more weight you'll lose. If you start now, by this time next week, you'll look and feel way lighter.

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.
