Diets make you feel bad. Try training your brain instead.

Here’s a New Year’s resolution you can keep: Stop dieting and start savoring your food instead.

That may seem like surprising advice, but there’s mounting scientific evidence to suggest that diets don’t work. Research shows that food restriction just makes you want to eat more. And over the long term, dieting can backfire, triggering your body’s survival defenses, slowing your metabolism and making it even harder to lose weight in the future.

A resolution to quit dieting doesn’t mean giving up on having a healthier body. But to successfully conquer a dieting habit, you’ll need to let go of old ideas about counting calories, banning your favorite foods and measuring success by a number on a scale.

So what’s the alternative? Many weight researchers are encouraging a new approach to healthy eating based on brain science. A variety of techniques that encourage mindful awareness of how we eat, acceptance related to the foods we want to eat and intuitive eating exercises can be used to quell cravings and reshape our eating habits.

“The paradigms around willpower don’t work,” said Dr. Judson Brewer, an associate professor in behavioral and social sciences at the Brown University School of Public Health who has studied mindful eating practices. “You have to start by knowing how your mind works.”

The case against restrictive diets

Kicking dieting habits this time of year is especially hard because of the allure of gimmicky weight-loss plans. Many established diet programs and dieting apps try to attract users with the promise that they’re not promoting a traditional diet, only to impose restrictive eating practices once you sign up.

Traci Mann, who heads the health and eating laboratory at the University of Minnesota, notes that beyond the disappointment of not keeping weight off, dieting also impacts your body in a number of negative ways. Among other things, restrictive eating can impact memory and executive function, lead to obsessive food thoughts, and trigger a surge in cortisol, a stress hormone.

“A diet is an unpleasant and short-lived way to try to lose weight,” said Mann, author of “Secrets From the Eating Lab: The Science of Weight Loss, the Myth of Willpower, and Why You Should Never Diet Again.” “You might take it off in the short term, but it comes back. It happens no matter who you are; it happens to people with great willpower and to people with crappy willpower.”

How eating habits are formed

Brewer, an addiction psychiatrist, has tested a number of mindfulness practices to help people quit smoking, lower anxiety and reduce emotional eating. He has also created an app called Eat Right Now that uses mindfulness exercises to help people change their eating habits.

One Brown University study of 104 overweight women found that mindfulness training reduced craving-related eating by 40%. Another review by scientists at Columbia University found that intuitive and mindful-eating training often resulted in at least one benefit for metabolic or heart health, such as improved glucose levels, lower cholesterol or improved blood pressure

Brewer notes that eating behaviors, such as absent-mindedly snacking on potato chips or bingeing on dessert, are often the result of habit loops that get reinforced over time.

Habit loops can be formed from both good and bad experiences, says Brewer. Ice cream, for instance, is something we might eat during celebrations. The brain learns to associate eating ice cream with feeling good. Although there’s nothing wrong with ice cream, it can become a problem when we start eating it unthinkingly after an emotional trigger, such as when we feel stressed or angry. Now our brains have learned that ice cream also makes us feel good in times of stress, reinforcing the habit loop.

Try the eat well challenge

For this week’s Eat Well Challenge, start practicing awareness by slowing down and thinking about what you’re eating and why you’re eating it. Try not to focus on weight loss, food restriction or eliminating favorite foods from your diet. Avoid labeling foods as “good” or “bad.” Your goal this week is to focus on the tastes and textures of food, and how you feel before, during and after eating.

It can take time to learn how to bring mindful awareness to what you’re eating, so be patient. In one study, it took participants at least 10 to 15 tries — and for many people it took 38 or more attempts — to begin to reshape eating behaviors. (I will be offering extra tips and coaching via text message during the challenge this month. Text the word “Hi” (or any word) to 917-810-3302 for a link to join. Message and data rates may apply.)

Here are two simple exercises from Brewer’s Eat Right Now program to get you started.

Begin with a premeal warmup.

Before every meal this week, try this simple awareness exercise. There’s no need to track what you eat or restrict your diet. Just check in with your body every time you eat. On a scale of zero to 10, with zero being an empty stomach and 10 being uncomfortably full, how hungry are you right now? Next, look at the food, observing the textures and colors. Now smell your food. Finally, pick up your fork and take your first mindful bite. As you chew, put your fork down and pay careful attention to how the food tastes and feels in your mouth. After several bites, check in with your body to see if you’re hungry or full.

Map your eating habits.

Use this exercise to work on an eating behavior you’d like to change, such as excessive snacking or ordering fast food. Our eating habits have three elements: a trigger, a behavior and a result. By mapping your habits, you can provide your brain with new information about how the habit really makes you feel.

— Start by choosing one eating behavior you’d like to change. Maybe you want to snack less during the day, or cut back on takeout or indulgences such as cookies, potato chips or ice cream. Although there’s nothing wrong with enjoying these foods, you’ve identified this as a problematic eating behavior. Why is that?

— Now think about what triggers this behavior. Is it an emotion, such as anger or stress, or are you rewarding yourself with a treat? Or it could be a situation, such as watching television or grocery shopping when you’re hungry.

— Focus on the result. Before you eat, ask yourself some questions. What am I getting from this? How will eating this food make me feel? Think about how you felt the last time you ate it. Did you enjoy it? Did you end up eating too much? Did you feel uncomfortably full or nauseous? Did you feel guilty later and beat yourself up for eating it? Thinking about how a food makes you feel before, during and after you eat updates the information your brain has about how rewarding (or not) a food really is. And it can help break the hold a particular food has on you.
