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.

Choose 4 of these tips minimum; the more you implicate into daily life, the more pounds you will drop. 

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.

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.

Any workout that gets your heart rate up will burn calories. But you’ll use more calories if you pick a cardio routine that engages multiple muscles simultaneously, says Wendy Larkin, personal-training manager at Crunch’s Polk Street gym, in San Francisco.

Three to consider: spinning, cardio kickboxing, and boot-camp workouts. Half an hour of each torches 200 to 300 calories while toning up your arms, legs, and core so everything appears sleeker and tighter.

You’ll burn even more calories per session if your workout incorporates interval training: alternating short bursts of intense cardio with slower activity. Experts aren’t sure why it works, but trainers swear by it.

These gym-class staples will help sculpt muscle, so you’ll sport a more streamlined appearance. Do three sets of 12 of each exercise every other day. “Push-ups target your upper body, while lunges work your butt, hips, and thighs,” says Larkin. Quick tip: Make sure your back and legs remain in a straight line during your push-ups; it’ll improve muscle tone. Also, you can build even more muscle with the lunges if you hold free weights in each hand while doing them.

That extra half an hour, whether you sleep 5 hours or 8, can refresh you enough that you will make better food choices (in other words, no quick sugar fix for breakfast in search of energy) and won’t feel lethargic and skip the gym, says registered dietician Esther Blum, author of Eat, Drink, and Be Gorgeous. More restful sleep (7 to 8 hours is best) also boosts your metabolism. And since your body builds muscle while you snooze, getting zzz’s equals better muscle tone.

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.”
