A coworker can’t stop talking about his juice fast. Your sister swears by her new no-carbs-allowed plan. Your neighbor extols the virtues of eating like a caveman. It’s easy to gravitate toward these shiny objects in crash-diet form because they make weight loss sound so simple. All you have to do is drink this or cut out that to get results, right? But the payoff may not last.
“Fad diets are tempting and may work short-term, but they’re not doable for the long-term and as a result, any weight lost is often regained,” says Michelle Cardel, PhD, R.D., senior director, global clinical research and nutrition at WeightWatchers®. They often are super restrictive and ban long lists of foods, which, let’s face it, is tough to stick to in the real world. On top of that, rapid weight loss can be dangerous, leading to issues like nutrient deficiencies and gallstones.
So if trendy fad diets are out, what’s in? Losing weight in a more natural, sustainable way. Whether you’re hoping to go down multiple sizes or lose those last five stubborn pounds, the key to successful weight loss is building healthy habits that you can maintain. The following simple steps, all backed by scientific research and approved by WeightWatchers’ team of scientific and nutrition experts, show you how to lose weight naturally. Try working them into your daily routine, and you’ll notice results—no diet supplements, gimmicks, or bread bans required.
1. Drink (a lot of) water
Put that reusable water bottle to work by drinking more water or other unsweetened beverages. “Drinking more water can help with satiety,” says Vivek Gupta, M.D., MPH, a board-certified obesity medicine doctor and owner of Mindful Weight Loss in Redondo Beach, California. sipping water satisfies your thirst without tacking on extra calories (the same can’t be said for sweetened drinks.)
Everyone has their own hydration needs based on things like age and activity level, but a rough rule of thumb is to divide your weight by two (so if you weigh 150 pounds, aim for 75 ounces of water a day through food and drink). If you want to up your H2O intake, keep a water bottle within easy reach, like on your desk or in your tote. At the very least, try to drink water with each meal and before, during, and after exercise.
2. Swap out added sugar
Eating a diet high in added sugar—the kind that’s added to foods during processing or preparation—may set the stage for obesity and other chronic diseases by increasing the calories in a food or beverage and making it harder to lose weight.
Take a look at what you eat and drink that is high in added sugar and make some simple substitutions. For example, switching soda for water and other unsweetened or diet beverages helped people shed roughly 2% to 2.5% of their body weight in six months, according to a study in American Journal of Clinical Nutrition. Craving something sweet? Choose a food with natural sugars, like grapes, mangoes, and berries. Yes, they’re all fruit. But, more importantly, they have another f-word in common: fiber. This nutrient can help you skirt a post-snack spike in blood sugar, something research shows can lead to overeating.
3. Squeeze in more sleep
Between work, having fun, and family duties, sleep often gets the short end of the stick. But not getting enough shut-eye triggers changes in hormones like ghrelin and leptin, which make you feel hungrier than you otherwise would. Sleeping too little also affects your ability to self-regulate your cravings, says Gupta. In other words, it’s much harder to turn down the siren call of that cookie when you’re exhausted.
If you’re reading this, nodding your head in agreement (or because you’re literally nodding off!), it’s time to move up your bedtime to ensure you get the recommended 7 to 8 hours of quality sleep a night. Want some motivation? According to a 2022 JAMA Internal Medicine study, sleep-deprived adults (defined as those who regularly slept less than 6.5 hours/night) who were overweight ate 270 fewer calories a day after they added about 72 minutes of slumber each night during a two-week intervention period.
4. Track your meals
The simple act of maintaining a food diary ups your odds for losing weight and keeping it off, says Kathryn M. Ross, Ph.D., MPH, an associate professor in the University of Florida’s Department of Clinical and Health Psychology in Gainesville. Not only does it force you to be more aware of what you’re putting in your mouth, but it also can help you see if you’re eating the right amount of calories for your goals. According to Ross, it would be like heading out on a road trip in a car without a gas gauge—there’s no way to track your progress.
Take notes on the kind of food, how much you ate, and what time you ate it. While you can always go the old school pen-and-paper route, the WW app makes food tracking a lot easier. That’s important since consistency is key. Research from the WW Success Registry showed that 74.4% of members who lost at least 20 pounds on WeightWatchers and kept it off for at least a year track their food most of the time or all of the time*.
5. Fill up on fiber
It’s not the sexiest nutrient in the world, but it sure is impactful. “Fiber slows down your digestion, which can help you stay full,” says Su-Nui Escobar, RDN, a registered dietitian nutritionist in Miami, Florida. The byproduct of staying full longer: You eat less and can lose weight. A 2015 study in the Annals of Internal Medicine revealed that people who focused on eating 30 grams of fiber a day—without making any other changes to their diet —lost a modest amount of weight and lowered blood pressure.
To get that amount of fiber in your day, plan meals and snacks around beans, lentils, and produce, such as raspberries (8 grams of fiber per cup), green peas (9 grams per cup), and cooked broccoli (5 grams per cup). And swap refined grains for their whole-grain counterparts: Brown rice has about 3.5 grams of fiber per 1 cup cooked while the same amount of white rice only has about 0.5 grams.
6. Set specific goals
Having something to aim for can boost your motivation. One 2016 study in the Journal of Human Nutrition and Dietetics found that people who set goals as part of a weight-loss plan were more likely to have shed 10% of their weight after a year compared to those who didn’t.
Set a clear and measurable diet or exercise goal that you can achieve right now. You can always change your goals as you hit them and as these goals become habits. “Walk at least 15 minutes after work daily” is better than “exercise more.” because it’s specific and measurable. It outlines what to do (walk), for how much time (15 minutes), and when (every day after work), whereas “exercise more” is missing all the details of what, how, and when. Also focus on a goal you can work actively toward rather than a behavior you want to stop. For example, instead of swearing off fried foods from now until the end of time, commit to eating at least one serving of vegetables at each meal.
7. Plan and prep meals
When you’re busy and don’t know what’s for dinner, it’s more tempting to go for the easy option, like the restaurant drive-through, rather than the more time-intensive choice of thinking about what to cook, ensuring you have the ingredients on hand, and making a meal at home. A simple solution: Meal plan and prep as much as you can ahead of time. Knowing what you’re going to eat that week and having a portion ready to go can also help you eat more whole foods (which are full of nutrients without things like added sugar) and cook more of your own meals—something that research shows can help you eat fewer calories, fat, and sugar.
If you’ve never done this before, meal prepping can feel overwhelming, but it doesn’t have to be. Start by picking one or two recipes you want to make that week, grabbing the ingredients you need from the store, and doing what you can in advance, like chopping up veggies, marinating meat, or even fully cooking some of the components like rice.
8. Get moving
This will come as a surprise to absolutely no one, but physical activity is important for natural weight loss: A review of 33 studies found that people who exercised regularly and changed what they ate lost 20% more weight than those who only did the diet changes. They were also more likely to maintain that weight loss. On top of that, research shows that being active can help you be more resistant to stressful situations (and high levels of stress are a risk factor for obesity).
Now for the fun part: You can (and should) choose any activity you like. “The best workouts are the ones you enjoy doing and will keep doing regularly and over the long term,” says Cardel. Challenge your kids to a dance-off, walk your pup around the neighborhood, or even sneak in some strengthening moves while you cook. You can also break your activity up into smaller chunks: Try squeezing in 5 or 10 minute bouts of exercise—a plank in the morning, a walk at lunch—a few times throughout your day.
9. Pack on protein
When you lose weight and are burning more calories than you’re eating, your body recruits both fat and muscle tissue for energy. Eating more protein helps you maintain that muscle mass, says Gupta. This won’t just help you stay strong, it will also support fat loss and help keep your metabolism higher (muscle burns more calories than fat). Eating protein also fends off hunger: It keeps you fuller and more satisfied than carbs or fat, according to a study in the American Journal of Clinical Nutrition.
Aim to get some protein at each meal and snack, suggests Escobar. You should get at least 0.36 grams of protein per pound of body weight daily; that’s 54 grams for someone who weighs 150 pounds. High-protein foods include not just poultry and fish, but also vegetarian sources like Greek yogurt, eggs, beans, lentils, tofu, and quinoa.
10. Don’t forget breakfast
Not everyone trying to lose weight has to start their day with breakfast, but if you wake up hungry, tend to snack in the a.m., or feel exhausted throughout the morning, make sure you eat something. A 2021 study in Medicine reports that people who eat a daily morning meal at least 4 times per week have a reduced risk for obesity, type 2 diabetes, and high blood pressure compared to those who ate a daily morning meal 3 times per week or less. Other research shows that regularly having breakfast is linked to being more successful at keeping weight off after losing it.
Think of breakfast as a great way to add nutrients to your day. Aim to get a mix of protein and fiber to help you stay satisfied until lunch. A few favorites: A veggie omelet, Greek yogurt with fruit, or avocado and egg on whole-wheat toast.
11. Check your portions
Over the past few decades, American’s portions have grown bigger and bigger. That’s bad news since research shows that people tend to consume more calories when they’re served more food. It makes sense: You’re probably going to make a big dent in a plate of pasta no matter how big of a serving it is.
If it’s been a while since you’ve seen what an actual serving of rice or chicken looks like, measure out your portions to show you how much you’re really eating. That could mean whipping out the measuring cups and tablespoons, or you could use your hand as a quick guide: A one-ounce serving of nuts is roughly the size of a poker chip in your palm while three ounces of meat is roughly the size of your palm.
The bottom line
The harder it feels to lose weight, the harder it can be to keep it off. That’s why choosing small lifestyle changes is an expert-approved approach. You’ll create a more natural path to weight loss and maintenance and feel great along the way. You don’t need to adopt all of the above habits, but pick and choose a few to start with. Then, once those feel automatic, try a few more.
