The devil is in the details -- and nowhere is the cliché truer than with weight loss. It's the small decisions that add up to change, and that's a good thing, says William Dietz, MD, PhD, at the CDC: "If you can count it, you can change it." The 10 countable steps that follow will add up to victory over unwanted pounds. But don't try them all at once. "It's like renovating a house; most people do better taking one room at a time," says John Jakicic, PhD, director of weight management at the University of Pittsburgh. "Start with the easiest tactic. Once you master it, move on."

1. Weigh yourself one time per day
Why It Works
Weekly weigh-ins are a staple of many popular diet programs, but studies now show that daily weighing is the key to lasting loss. When researchers at the University of Minnesota monitored the scale habits of 1,800 dieting adults, they found that those who stepped on every day lost an average of 12 pounds over 2 years (weekly scale watchers lost only 6) and were less likely to regain lost weight. The reason: "The more often you monitor your results, the quicker you can catch the behavioral slip that causes weight gain," says Jakicic.

Who It Helped
Heidi Hurtz, 29, of Los Angeles: "I was in denial about my size, so I never used a scale. When I started weighing daily, I lost 7 pounds in 2 weeks. I loved the immediate gratification, and eventually lost 77 pounds."

Add It In
Step on the scale first thing every morning, when you weigh the least. Expect small day-to-day fluctuations because of bloating or dehydration, but if your weight creeps up by 2 percent (that's just 3 pounds if you weigh 150), it's time to pass up the bread.

2. Watch no more than 2 hours of TV a day
Why It Works
TV junkies miss out on calorie-burning activities like backyard tag with the kids; instead, they become sitting ducks for junk-food ads. One recent study found that adults who watch more than 2 hours of TV per day take in 7 percent more calories and consume more sugary snacks than those who watch less than an hour a day.

Who It Helped
Christy Taylor, 27, of Sylacauga, Ala: "TV was one reason I weighed 220 pounds. I watched it constantly. My blood pressure skyrocketed during pregnancy, and when it didn't come down after my son was born, I decided to try to limit myself to one show a day. That was 10 months ago, and I've since lost 32 pounds."

Add It In
Wean yourself off the tube by introducing other activities into your life. Eliminate the temptation to watch between-show filler by recording your must-see programs so you can fast-forward through the ads. Or subscribe to a mail order DVD service like Netflix, and make a movie the only thing you watch all day.

3. Contact a friend three times per week
Why It Works
"Long-term weight loss requires support," says Marion Franz, RD, a nutrition consultant in Minneapolis. Her study review found that people who met regularly with a dietitian or attended groups like Weight Watchers were more likely to maintain their losses than those who didn't.

Who It Helped
Maggie Ramos, 39, of Houston: "When I plateaued for months, my friend Nancy stepped in and cheered me on until I lost it all."

Add It In
If you can't attend group meetings, announce your weight loss intentions so friends can support you, says Franz. And add a dieter pal to your regular call or e-mail list, too.

4. Eat four grams of fiber in every meal or snack
Why It Works
A high-fiber diet can lower your caloric intake without making you feel deprived. In a recent Tufts University study, women who ate 13 g of fiber or less per day were five times as likely to be overweight as those who ate more fiber. Experts see a number of mechanisms through which fiber promotes weight loss: It may slow down eating because it requires more chewing, speed the passage of food through the digestive tract, and boost satiety hormones.

Who It Helped
Monique Hester, 41, of North Richland Hills, Texas. "I started a diet that had me consuming more than 25 grams of fiber daily, and before I knew it, I'd lost 23 pounds. I don't even like white bread anymore. I want something I can crunch and chew."

Add It In
To get 25 grams of fiber a day, make sure you eat six meals or snacks, each of which contains about 4 grams of fiber. For instance, Hester started her day with grapes (1 cup = 1.4 grams of fiber) and cracked wheat toast (two slices = 6 grams) or oatmeal (1 cup = 4 grams). She often had a cup of black bean soup for lunch (4.4 grams) with a slice of cracked wheat bread. One good trick: For to-go snacks, buy fruit; it's handier than vegetables, so it's an easy way to up your fiber intake. For instance, one large apple has just as much fiber (5 grams) as a cup of raw broccoli.

5. Take five (thousand) extra steps a day
Why It Works
A typical person takes about 5,000 steps per day between going to work, running errands, and doing chores around the house. Doubling that number can have significant health benefits: higher "good" HDL cholesterol levels, lower blood pressure, improved glucose control, and yes, a lower number on the scale. Walking more steps per day also leads to a lower percentage of body fat and slimmer waists and hips, reports a recent University of Tennessee study of 80 women. An earlier University of South Carolina study of 109 people showed that those who took fewer than 5,000 steps per day were, on average, heavier than people who took more than 9,000.

Who It Helped
Joanna Webb, 34, of Queen Creek, Ariz.: "I started walking when my daughter was 2 months old. I couldn't even make it around the block without stopping. I kept at it until I could walk 6 nights a week with my husband, our 5-year-old, and the baby. Now I've lost 35 pounds."

Add It In
Wear a pedometer to make sure you log your 5,000 extra steps, or aim for about 50 minutes of extra walking (2 1/2 miles) per day. In the Tennessee study, "Some of the women walked with friends; others increased their steps by taking the stairs and parking farther away," says lead researcher Dixie Thompson, PhD.
