The Science-Backed Strategies That Will Actually Help You Eat Better

Many of the strategies that you think will work don’t. Here are the surprising things that do.

We know what we should eat. Trouble is, most of us have a hard time sticking to it.

Researchers are racing to understand what pushes people to make healthier food choices. They are finding that broad resolutions to “eat better” are less effective than setting a couple of smaller rules, that eating with other people is helpful and that grocery shopping online can be better than going to the store.

The issue is urgent: The number of Americans who are overweight or have obesity is rising. Nearly three-quarters of US adults ages 20 and older are overweight or obese, according to 2017-2018 figures from the Centers for Disease Control and Prevention, and some surveys have found that obesity rates rose further during the pandemic.

Doctors and scientists broadly agree that a healthful diet is rich in vegetables, fruits, whole grains and lean meat and poultry—and is composed of fewer foods linked to poor health, including sugar-sweetened foods and drinks, refined grains and large amounts of red meat. Yet most of Americans don’t consume the recommended amount of vegetables, and three-quarters overeat refined grains, such as white bread, according to a government report.

“We’re living in a time where there’s food everywhere. You go to buy a hammer and there’s soda in the checkout line,” says Erica Kenney, assistant professor of public health nutrition at the Harvard T.H. Chan School of Public Health. “People berate themselves, but they are fighting against the environment.”

Whether you are trying to overhaul your diet, resist the peanut-butter cups in the checkout aisle or maintain the good habits you already have, research suggests some ways to make healthy eating easier.

Set one or two specific rules, and stick to them.

People are more likely to act on a plan if it consists of simple steps, psychology research has found. Having one broad goal—such as, “I’m going to eat better”—generally isn’t effective.

Pick one or two specific eating rules and stick to them—and think of yourself as someone who doesn’t do those things. For instance: I don’t consume sugary drinks. Or I don’t eat fried foods. Or I don’t eat dessert during the week.

Restricting yourself in multiple ways makes it harder to stick with good intentions, says Christina A. Roberto, associate professor of health policy at the University of Pennsylvania’s Perelman School of Medicine.

Conversely, setting a rule “just takes the decision out of it,” says Deborah F. Tate, professor at the Nutrition Research Institute at the University of North Carolina.

Make a grocery list, and shop online.

Making a shopping list of healthful foods can encourage you to avoid impulse buys when you are at the store, says UNC’s Dr. Tate.

Shopping for groceries online might be even more effective since unhealthy items aren’t right in front of you. Research has found that people tend to make better food choices farther in advance of eating, so the delay between making an online order and receiving it could be helpful, Dr. Roberto says.

People looking to lose weight who shop online buy fewer high-fat foods and fewer items overall compared with those who shop in person, according to a 2007 study in the International Journal of Behavioral Nutrition and Physical Activity that followed 28 participants over eight weeks.

One caveat: Be wary of online ads trying to persuade you to buy items you didn’t plan to purchase. That marketing can derail your good intentions.

Good sleeping begets good eating.

Not sleeping enough (generally less than six-and-a-half hours a night) is linked to weight gain, scientific studies have found. Sleep experts generally recommend that healthy adults get between seven and nine hours of sleep a night.

When we are awake longer, we have more time to eat. And there are biological changes that occur when we don’t sleep enough that can lead to overeating.

“Some research suggests there are potential changes to appetite-related hormones when we have short sleep,” says Alyssa Minnick, a postdoctoral fellow in the Division of Sleep Medicine at the University of Pennsylvania’s Perelman School of Medicine. When we are sleep-deprived we tend to crave more high-fat foods, too, she says.

Penn researchers found that study participants allowed to sleep just four hours a night for five nights ate on average an extra 550 calories daily. The paper was published in 2013 in the journal Sleep. More recent research has had similar findings.

Don’t eat alone.

When we eat with family and friends we tend to make more well-rounded meals with vegetables, proteins and other components, says Barbara J. Mayfield, a registered dietitian in Delphi, Ind. We also tend to eat more slowly, and often mindfully, when with others, she says, making us better able to notice when we are full.

Eating with others who are also committed to healthy eating can help us achieve our goals, says Rebecca Seguin-Fowler, associate director of the Institute for Advancing Health Through Agriculture at Texas A&M University. You are more apt to skip dessert when your dining companions are too, she says.

Studies have found that when one person in a household is trying to improve their diet and lose weight, the other members lose weight too, even if they aren’t trying to, says Amy Gorin, interim vice provost for health sciences at the University of Connecticut.

What We Fight About When We Fight About Money

New research tackles the source of financial conflict and what we can do about it

When couples argue over money, the real source of the conflict usually isn’t on their bank statement.

Financial disagreements tend to be stand-ins for deeper issues in our relationships, researchers and couples counsellors said, since the way we use money is a reflection of our values, character and beliefs. Persistent fights over spending and saving often doom romantic partnerships: Even if you fix the money problem, the underlying issues remain.

To understand what the fights are really about, new research from social scientists at Carleton University in Ottawa began with a unique data set: more than 1,000 posts culled from a relationship forum on the social-media platform Reddit. Money was a major thread in the posts, which largely broke down into complaints about one-sided decision-making, uneven contributions, a lack of shared values and perceived unfairness or irresponsibility.

By analysing and categorising the candid messages, then interviewing hundreds of couples, the researchers said they have isolated some of the recurring patterns behind financial conflicts.

The research found that when partners disagree about mundane expenses, such as grocery bills and shop receipts, they tend to have better relationships. Fights about fair contributions to household finances and perceived financial irresponsibility are particularly detrimental, however.

While there is no cure-all to resolve the disputes, the antidote in many cases is to talk about money more, not less, said Johanna Peetz, a professor of psychology at Carleton who co-authored the study.

“You should discuss finances more in relationships, because then small things won’t escalate into bigger problems,” she said.

A partner might insist on taking a vacation the other can’t afford. Another married couple might want to separate their previously combined finances. Couples might also realize they no longer share values they originally brought to the relationship.

Recognise patterns

Differentiating between your own viewpoint on the money fight from that of your partner is no easy feat, said Thomas Faupl, a marriage and family psychotherapist in San Francisco. Where one person sees an easily solvable problem—overspending on groceries—the other might see an irrevocable rift in the relationship.

Faupl, who specialises in helping couples work through financial difficulties, said many partners succeed in finding common ground that can keep them connected amid heated discussions. Identifying recurring themes in the most frequent conflicts also helps.

“There is something very visceral about money, and for a lot of people, it has to do with security and power,” he said. “There’s permutations on the theme, and that could be around responsibility, it could be around control, it could be around power, it could be around fairness.”

Barbara Krenzer and John Stone first began their relationship more than three decades ago. Early on in their conversations, the Syracuse, N.Y.-based couple opened up about what they both felt to be most important in life: spending quality time with family and investing in lifelong memories.

“We didn’t buy into the big lifestyle,” Krenzer said. “Time is so important and we both valued that.”

For Krenzer and Stone, committing to that shared value meant making sacrifices. Krenzer, a physician, reduced her work hours while raising their three children. Stone trained as an attorney, but once Krenzer went back to full-time work, he looked for a job that let him spend the mornings with the children.

“Compromise: That’s a word they don’t say enough with marriage,” Krenzer said. “You have to get beyond the love and say, ‘Do I want to compromise for them and find that middle ground?’”

Money talks

Talking about numbers behind a behaviour can help bring a couple out of a fight and back to earth, Faupl said. One partner might rue the other’s tightfistedness, but a discussion of the numbers reveals the supposed tightwad is diligently saving money for the couple’s shared future.

“I get under the hood with people so we can get black-and-white numbers on the table,” he said. “Are these conversations accurate, or are they somehow emotionally based?”

Couples might follow tenets of good financial management and build wealth together, but conflict is bound to arise if one partner feels the other isn’t honouring that shared commitment, Faupl said.

“If your partner helps with your savings goals, then that feels instrumental to your own goals, and that is a powerful drive for feeling close to the partner and valuing that relationship,” he said.

A sense of mission

When it comes to sticking out the hard times, “sharing values is important, even more so than sharing personality traits,” Peetz said. In her own research, Peetz found that romantic partners who disagreed about shared values could one day split up as a result.

“That is the crux of the conflict often: They each have a different definition,” she said of themes such as fairness and responsibility.

And sometimes, it is worth it to really dig into the potentially difficult conversations around big money decisions. When things are working well, coming together to achieve these common goals—such as saving for your own retirement or preparing for your children’s financial future—will create intimacy, not money strife.

“That is a powerful drive for feeling close to the partner and valuing that relationship,” she said.
