There’s a fad diet for practically everyone.

But as fun as the diets may seem, it’s often difficult to stick with them for more than a few weeks. As a result few people actually see any long-term results.

Rather than trying one of those, here are 12 science-backed habits that can help boost your health and may help with weight loss as well.


Eat food you enjoy.

It may seem as if the easiest way to lose weight is to stop eating the foods you overindulge in. But this can be short-sighted, Lisa Sasson, a New York University nutrition professor, told Business Insider in 2015. “If you pick a diet with foods you don’t like, you’re doomed to fail,” Sasson said. Food is a pleasurable experience; if you cut out all the foods you like, you probably won’t stick to your plan.

And as studies continue to show, coming up with an eating regimen you can stick with is critical.


Portion sizes are key.

There's a psychological component to eating, especially when you have weight loss in mind. Being conscious of losing weight and sticking to the right portion sizes is half the battle, Sasson said. This phenomenon is why most people in studies lose weight, regardless of whether they're in the group assigned a special diet. Simply being studied can lead to people being more conscious of what they're eating.

But overall, keeping an eye on portion sizes is a great way to help avoid overeating - especially with portion sizes rising since the 1970s.


Pack your lunch.

Portion sizes in American restaurants have increased by as much as three times in the past 20 years, and it is changing what we think of as a normal meal.

"One way to keep calories in check is to keep food portions no larger than the size of your fist," Elizabeth G. Nabel, director of NIH's National Heart, Lung, and Blood Institute, writes.

If you're trying to control your portion sizes, it is best to pack your own lunch because restaurants will give you more calories than you need.


Stick with food that's packed with fiber and protein.

Fiber and protein help keep you feeling full. Processed foods like candy bars and cookies are often low in both of these ingredients and instead are "readily absorbable," Sasson said. That's why you don't feel as satiated after eating a bag of potato chips as you might after eating a fiber-filled baked potato.

In a review of weight-loss studies focusing on fiber, protein, and fullness, psychologists at the University of Sussex made the case for high-protein and high-fiber foods to be included in weight-loss plans because feeling full can help prevent overeating and spur weight loss.


Go Mediterranean.

As if you needed more excuses to eat as if you live on the Mediterranean (olive oil, pasta, hummus, tomato, and cucumber salad - what's not to love?), studies have shown that a so-called Mediterranean diet may help reduce the risk of heart disease and provide some potential memory-related benefits. And a recent study also found a link between the eating plan and a lower risk of breast cancer in older women.

According to Sasson, there may be an overlooked element of the Mediterranean diet: It may not be so much about what the people who live around the Mediterranean Sea are eating, but rather about what they're not eating, such as oversize portions and heavily processed food.


Get your calories from food, not liquids.

Juice and soda may taste better than plain old water, but the calories inside them can add up.

In a study of 173 obese women ages 25 to 50, researchers found that swapping out sweetened beverages with plain old water was linked with weight loss, independent from diet and exercise.


Give yourself options.

Sasson says having an eating plan with flexibility is key. Weight Watchers, for example, allows for a variety of different meal types. Having options for what you can eat can makes it easier to build that into your life, as opposed to a diet that sticks to the same five meals every week.

In a study of diets like Weight Watchers and Atkins that allowed for such flexibility, doctors and dietitians at Tufts University looked at 160 overweight people ages 22 to 72 on the diets over a one-year period. They found that the people who followed the popular diets saw more weight loss and a reduction in heart risk factors compared to those who didn't stick with the diets.


Never go grocery shopping when you're hungry.

One small study found that hungry shoppers grabbed one-third more junk food than full shoppers. So, just make sure that you're aware not only of what you're eating, but also of what you're buying.


Get a good night's sleep.

Beware the cravings that can come with feeling sleepy.

Researchers using functional magnetic resonance imaging (fMRI) scanned the brains of 25 men and women of average weight as they looked at images of delicious, fatty junk food. The participants were studied after a week of nine hours of sleep a night and then after a week of four hours of sleep a night.

When the participants were well rested, the reward centers of their brains didn't react nearly as much to the junk food photos as when they were lacking sleep, suggesting that we're subconsciously more attracted to fatty foods when we're tired and need energy.


Start each day right with breakfast.

There's a saying that breakfast is the most important meal of your day, and it may be true. Evidence suggests that an early meal kick-starts your metabolism, the process that breaks down the food you eat into energy. There's been a lot of back-and-forth on the topic, and a study published in July didn't see any effects of eating breakfast on the kids' ability to perform in each of the cognitive tests compared to kids who had not eaten breakfast.

But, of course, breakfast does provide vital nutrients to keep you energized throughout the day, so if you do eat breakfast, it's important to eat a morning meal that's highin protein and complex carbohydrates, but low in sugar.


Avoid diet drinks.

Roughly 20% of Americans drink at least one soda a day. For those drinking regular, switching to diet could lead to weight loss. But studies suggest that change may work only in the short-term.

In a study that ran from 1979 to 1996, researchers found from a sample of nearly 750 people age 65 or older, that those who drank diet soda on a daily basis had a 70% greater increase in waist size than people who drank it less regularly or not at all.

While there's no evidence to support the scary notion that artificial sweeteners increase our risk of cancer, there is reason to suspect that in the long run it won't help your waist line. Still, while these studies show only an association between drinking diet soda and putting on weight, you can't go wrong switching from a highly processed beverage to plain old water or seltzer.


Don't snack after dinner.

A short-term study of 29 young men showed that they consumed on average 238 fewer calories each day for two weeks when they were told not to eat anything between 7 p.m. and 6 a.m. And these calories they were no longer eating were coming mostly from high-fat, high-carb foods.
