But if navigating these choices seems confusing, that’s where Eat This, Not That! comes in. What really works are making little lifestyle tweaks, simple moves that help you slash calories, boost nutrition and build a healthy foundation. We’ve gathered up some of the easiest, most effective new tricks and tactics to help you shed those unwanted pounds and slim down for good.

While you may think you’re doing yourself and your waistline a favor by stocking up on sugar-free goodies, the well-meaning habit is likely doing more harm than good. In a 2012 study in The American Journal of Clinical Nutrition, researchers found that those who drank diet beverages had higher fasting glucose, thicker waists, lower HDL (good) cholesterol, higher triglycerides, and higher blood pressure. In other words, sugar-free cookies, soda, and the like may seem like the healthier option, but they contribute to a bulging belly and negatively impact your health in multiple ways.

Sure, you certainly need to drink plenty of water to help combat bloating, you can (and should!) also consume high-water content foods. Reach for cucumbers, tomatoes, watermelon, asparagus, grapes, celery, artichokes, pineapple, and cranberries — all of which contain diuretic properties that will also help you stay full due to their higher fiber content.

_{Yes, peanut butter is high in calories, but if you stick the real stuff—a tasty combo of peanuts and maybe a touch of salt—the legumes can earn a place as one of the best foods for weight loss. In addition to providing you with belly-slimming monounsaturated fats, tummy-filling fiber, and metabolism-boosting protein, peanuts also contain genistein, a compound that helps turn down the genes for obesity and reduces your body’s ability to store fat.}

As it turns out, almonds aren’t the only superstar nuts around. Studies have shown pistachios aren’t bad to snack on either. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for three months. One group was given 220-calories of pretzels as an afternoon snack, while the other sect munched on 240-calories worth of pistachios. About a month into the study, the pistachio group had reduced their BMI by a point and improved their cholesterol and triglyceride levels, while the pretzel-eaters stayed the same.

Speaking of things you find in the sea, oysters have also been shown to contribute to weight loss thanks to their impressive zinc content. One study found that obese people who consumed 30 milligrams of zinc per day—the equivalent of just six raw oysters—had lower BMIs, weighed less, and showed improvements in blood cholesterol levels. If oysters aren’t your thing, spinach, pumpkin seeds, and mushrooms are also excellent sources of zinc.

If you follow these two steps together, you should be able to lose weight in a week. But keep in mind that experts only consider one to two pounds per week to be healthy and realistic weight loss. So unless you make permanent changes to your lifestyle, any quick weight loss is not likely to last. If you're ready to lose weight and keep it off for good, take just one hour to set up a solid plan for long-term weight loss to get a better body that lasts.

Not only is drinking lemon water a healthy, low-calorie alternative to soda or juice, but lemons themselves have also been shown to contribute to weight loss. Just one of the citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of cortisol, a stress hormone that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain. Believe it or not, even the peel is beneficial because it is a potent source of pectin—a soluble fiber that’s been proven to help people feel fuller for longer. According to a study published in the Journal of the American College of Nutrition, participants who ate just 5 grams of pectin experienced more satiety.
^{High-calorie drinks. Sweetened beverages are full of calories. Drink water this week and avoid all alcohol (wine, beer, and cocktails), juice, sports drinks, sweetened teas, flavored coffee drinks, soda, and commercially flavored water (such as vitamin waters). You can also make flavored water with fresh lemon juice or other fruit if you don't like plain water. Stay hydrated, but avoid drinks that cause weight gain via empty (non-nutritive) calories.}
Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.
Weight loss ultimately comes back to the concept of calories in, calories out: Eat less than you burn and you’ll lose weight. And while it’s possible to lose water weight quickly on a low-carb diet, I certainly wouldn’t advocate for it. The diet itself can trick you into thinking that this eating style is working — when really, you might gain back what you lost as soon as you eat carbs again. That can feel incredibly dispiriting if you want results that last longer than a week.

While 1,200 may be the right number for some people, it can be super restrictive for others, says Jaclyn London, MS, RD, CDN, Nutrition Director at the Good Housekeeping Institute. That’s why we’re using 1,200 as our base, and encourage you to build upon these meal and snack ideas by doubling (or tripling, quadrupling …you get the point!) up on veggies at any opportunity — and adding more fruit at snack time, too. You can also add 1-5 ounces of protein at all meals if at any point you’re feeling like it’s just not enough food to keep you satisfied. The combo of fiber from produce and lean protein makes this an adaptable strategy that’ll help you lose weight safely — one meal (and snack) at a time!

Lately, we’re noticing protein-packed everything—from breads to nut butter and milk. While you don’t need to load up on weird franken-foods to amp up your intake of the nutrient, if you’re trying to drop a few pounds, then it’s wise to keep some high-protein snacks on hand. Noshing on these can prevent eating something high-calorie every time hunger strikes.
27. Use tech and other tools to your advantage. "I started out just by cutting little things like soda out one by one so I wouldn't burn myself out mentally and give up. I then discovered counting calories on MyFitnessPal, which was [a huge help] for me in my weight loss. A few years in, I lost my way a little bit and found Renaissance Periodization diet templates, which helped me rebuild a healthy relationship with food."

There's a reason (well actually, many reasons) why lentils are considered one of the world's healthiest foods. With 13 grams of protein and 11 grams of fiber per serving, this legume—another member of the pulse family—will keep you feeling full for hours in between meals. They're a great source of fat-burning resistant starch, too, with 3.4 grams in a half-cup serving.

_{“I wish people knew that there is no one-size-fits-all diet that works for everyone. Individuals have different food preferences, dining habits, schedules, body types, past experiences, and obstacles. Stop falling for restrictive diet plans, America! Start by changing one simple habit and build from there,” Stephanie Brookshier, RDN, ACSM-CPT tells us in 22 Top Weight Loss Tips, According to Nutritionists.}
Avocados are rich in monounsaturated fatty acids, dietary fiber, potassium and phytochemicals. People who eat avocados tend to have lower BMI, body weight and waist circumference than people who skip this green superfood, per a study in Nutrition Journal. While avocados are higher in calories than other fruits and vegetables, their satisfying fat and fiber combo may help you slim down. Add some to your salad, sandwich or taco night for a burst of creaminess and flavor.
