According to a survey by Marketdata Enterprises, the average American dieter makes four or five attempts to [lose weight](http://www.health.com/health/gallery/0,,20639075,00.html) each year. It’s a vicious cycle: “After a while, you feel discouraged when you don’t get results, and that can wear away at your [motivation](http://www.health.com/health/gallery/0,,20656688,00.html),” says Dawn Jackson Blatner, R.D., author of _The Flexitarian Diet._ These dieting upgrades should do the trick once and for all. **Diet fail #1: Counting every single calorie** Don’t get us wrong—plenty of research has shown that we routinely underestimate the number of [calories](http://www.health.com/health/gallery/0,,20911507,00.html) in our food. But when you’re trying to lose weight, diet quality matters more than calorie count. A 2012 study in _JAMA_ found that people on a low-carb, low-glycemic diet burned more calories than those who followed a low-fat, high-carb diet. “Foods that are high in carbs slow metabolic rates compared with diets higher in fat and [protein](http://www.health.com/health/gallery/0,,20692801,00.html),” says David Ludwig, MD, director of the New Balance Foundation Obesity Prevention Center at Boston Children’s Hospital. What’s more, high-glycemic foods (sugar, bread, potatoes) spike blood sugar and stimulate cravings. **Diet redo** Focus on foods that are low in junky carbs and rich in [protein](http://www.health.com/health/gallery/0,,20718479,00.html). Just choose your protein carefully. A 2015 study in the _American Journal of Clinical Nutrition_ found that folks who upped their intake of [yogurt](http://www.health.com/health/gallery/0,,20754525,00.html), seafood, skinless chicken and nuts lost the most weight; those who increased their consumption of red and processed meat put on pounds—particularly when it was paired with high-carb foods. (But swapping the carbs for low-glycemic foods, like veggies, helped lower weight gain.) **Diet fail #2: Limiting yourself to mini meals** You’ve heard it a million times: Small, frequent meals help you lose weight by revving your [metabolism](http://www.health.com/health/gallery/0,,20835155,00.html) and controlling your appetite. But dividing a 1,200-calorie-per-day plan into six meals can leave you with a growling stomach and short-circuit your diet. “You need protein, [fiber](http://www.health.com/health/gallery/0,,20306753,00.html) and carbs in each meal to feel full, and it’s tough to get that in just 200 calories,” explains Blatner. In most cases, people end up overeating at their small meals—it’s easy for a teaspoon of almond butter to unintentionally become three. Plus, says Blatner, “because you’re faced with more food decisions, you’re constantly taxing your willpower.” **Diet redo** Think three solid meals a day. “You’re a lot more likely to stick to a diet that’s simple—planning six healthy meals is overwhelming,” says Blatner. While you’re at it, front-load calories. A 2013 study in _Obesity_ found that people who made [breakfast](http://www.health.com/health/gallery/0,,20406798,00.html) their biggest meal were at least twice as likely to lose weight and trim their waistlines as those who “saved” calories for dinner. **Diet fail #3: Always eating the same foods** This tip gained popularity after a 2011 study showed that women who ate mac and cheese daily for a week took in around 100 fewer calories each day than they normally did. But a recent study conducted by Hollie Raynor, PhD, associate professor of nutrition at the University of Tennessee, Knoxville, revealed that when people on a calorie-restricted diet were limited to two types of junk food, they didn’t lose more weight than dieters who could eat any kind they wanted. **Diet redo** Branch out. As Raynor says, “Experimenting with different fruits and [vegetables](http://www.health.com/health/gallery/0,,20831770,00.html) could prompt you to eat more of them.” Vary your protein, too—a lot of us skimp on superstars like fish and [beans](http://www.health.com/health/gallery/0,,20932754,00.html). **Diet fail #4: Doing daily weigh-ins** Regular scale checks have been linked to better [weight-loss maintenance](http://www.health.com/health/gallery/0,,20486520,00.html), but you can overdo it. One _Journal of Obesity_ study found that women benefited less from daily weigh-ins than men. “Hormonal fluctuations can cause water retention, making it harder to get an accurate reading,” says Liz Weinandy, R.D., of the Ohio State University Wexner Medical Center. “Plus, weight is more likely to be an emotional issue for women. Someone who gets a bad reading can think, ‘What’s the use of trying?'” **Diet redo** Hop on the scale about once a week—enough to sanely stay on track, according to a _Plos One_ study. Wednesday is good, say Finnish researchers, since most of us get heavier on weekends and then drop the weight during the week. **Diet fail #5: Trying to work off the pounds** Eat less, move more: It’s the most basic advice, and yet the two strategies aren’t equally effective. “Weight loss is 80 percent diet, 20 percent exercise,” says Craig Primack, M.D., an obesity medicine specialist at the Scottsdale Weight Loss Center in Arizona. Calorie burn from [exercise](http://www.health.com/health/gallery/0,,20689183,00.html) is too minimal to compensate for subpar food choices. The average person would have to walk 35 miles to burn the 3,500 calories it takes to lose just 1 pound. **Diet redo** Keep active _and_ [clean up your diet](http://www.health.com/health/video/0,,20905351,00.html). In fact, women who did both lost more weight than those who did only one or the other, showed a study in _Obesity._“Exercise also makes people feel better about their bodies and themselves,” notes Dr. Primack, “and that makes it easier to stay with a diet and workout plan.” **Unexpected Ways to Eat Less** _Distract yourself_ In a study in the journal Appetite, people who played Tetris for three minutes found that their desire to nosh diminished faster than those who weren’t distracted. We tend to visualize [cravings](http://www.health.com/health/gallery/0,,20847561,00.html); mind-stimulating activities stop us from picturing that brownie. _Go to sleep earlier_ Lack of shut-eye can add flab, says a Mayo Clinic study that found that [sleep-deprived people](http://www.health.com/health/gallery/0,,20906153,00.html) consumed an extra 549 calories per day, compared with those who were well-rested. Try to follow the National Sleep Foundation’s guidelines and get seven to nine hours a night. _Eat more vivid foods_ When food contrasts with the color of a plate, you tend to eat less, per research from the Cornell University Food and Brand Lab. People devoured more spaghetti and sauce when it was served on a red plate versus a white one; portion size wasn’t obvious, so they OD’d. _Turn off the TV_ Seeing commercials for food while watching television can trigger people to snack, according to a study published in the journal Health Psychology. That sounds like the perfect excuse to settle in for an (ad-free) [Netflix binge](http://news.health.com/2014/06/06/5-ways-to-make-your-netflix-binge-a-little-less-bad-for-you/) instead. Or just pick up a good book.

[ MUSIC ] I've always heard that if you eat late at night, it turns to fat, and I don't want that to happen. So I try not to eat after seven. Weight loss plans often have all kinds of rules to remember. One we hear all the time is never eat past eight pm If you work late like me, or have a hectic schedule, that advice can be hard to swallow. But the latest research suggests, you may not have to. [ MUSIC ] A study involving female monkeys found that eating at night is not associated with weight gain. Ditto for surveys of humans which have turned up no link to nighttime meals and weight gain or obesity. The theory behind the advice is that our metabolism slows down during sleep, so calories consumed late in the evening aren't burned as readily. While that may be true, our bodies do continue to burn calories while we sleep. [ MUSIC ] More important than when we eat is how much we eat. In studies where late night eating was tied to weight gain... People often snacked, or ate additional meals at night. Obviously chowing down on pizza or ice cream all night can lead to extra pounds. But the reason is the calories, not the clock. There is one instance where the timing of meals does matter. Studies show that skipping breakfast is associated with weight gain. So start eating early and stop after dinner. That's timeless advice that can benefit us all.
