The latest Dietary Guidelines no longer give a daily cap for dietary cholesterol (previously it was 300 milligrams), because there’s abundant evidence that dietary cholesterol (found only in animal foods) has little if any effect on most people's blood cholesterol. Rather, saturated fats raise LDL (“bad”) cholesterol more than dietary cholesterol does. But don't go overboard with cholesterol-rich foods, since many of them are also high in saturated fats. And if you have cardiovascular disease or diabetes, ask your doctor if you should limit dietary cholesterol.
“Fish is a great source of satiating protein and is typically lower in calories than other animal proteins,” says Maggie Moon, MS, RD, author of The MIND Diet. “Sardines are a sustainable seafood choice, which are packed with heart-healthy and brain-healthy omega-3 fats,” she says. These healthy fats can help decrease inflammation and improve your mood while dieting.
Coconut oil may be high in saturated fat, but that doesn’t mean you should write it off completely, especially when it comes to weight loss. In fact, a study of 30 men published in Pharmacology found that just two tablespoons per day reduced waist circumference by an average of 1.1 inches over the course of a month. What’s more? At roughly 117 calories per tablespoon, coconut oil (which has a versatile high smoke point) is an ideal cooking companion so long as you don’t use it every day and rotate in other cooking oils such as heart-healthy EVOO.
Apples contain pectin, an ingredient that naturally slows digestion and encourages feelings of fullness. Studies show that eating a whole apple with your meal (as opposed to apple juice or applesauce) is a natural appetite suppressant, helping you consume fewer overall calories without feeling deprived. Sass likes using shredded apple in slaws and stir-fry, or mixing them into burger patties to add moisture.
As long as this popular crunchy treat isn't doused in movie-theater butter, it makes an excellent weight-loss snack. Not only is popcorn high in fiber, it even delivers some protein. A 1-ounce serving of air-popped corn (about 3½ cups) has 4 grams of fiber, almost 4 grams of protein and clocks in at 110 calories. This combination makes it a snack with staying power. Popcorn is filled with air, so you get a pretty large portion without a lot of calories. You can eat 3 whole cups of popcorn for only 100 calories.
Popular diets, often referred to as fad diets, make promises of weight loss or other health advantages such as longer life without backing by solid science, and in many cases are characterized by highly restrictive or unusual food choices.:296 Celebrity endorsements (including celebrity doctors) are frequently associated with popular diets, and the individuals who develop and promote these programs often profit handsomely.:11–12
Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
“This warming—or cooling—beverage serves a dual purpose. Not only is it full of antioxidants and other healthy phytochemicals, but it has the benefit of slightly increasing your metabolism,” says Harris-Pincus. Sipping tea in the evening instead of snacking, or trading in your PSL for a cup of green tea will lower your calorie intake and help you burn a few extra calories. Just be sure to keep it unsweetened.
Although white potatoes offer some potassium and fiber, sweet potatoes reign supreme in the nutrition department, meaning you should consider adding sweet potatoes to your diet. A large sweet potato contains around 4 grams of satiety-boosting protein, 25 percent of the day’s belly-filling fiber, and 11 times the recommended daily intake of vitamin A. What’s more? It’s less than 200 calories.
Coconut oil is having a moment right now: it can be used as a butter or olive oil substitute in everything from baked goods to salad dressing, and can even be used as an alternative to milk in lattes (yes, really). Sass is a fan of the heart-healthy oil whipped into smoothies, and you can also use it to sauté veggies, sear fish, or as an olive oil replacement in soups and stews. (It's also a must-add to your beauty routine, and makes a wonderful natural moisturizer for skin and hair.)
A myriad of different teas have been shown to aid weight loss, and green tea is no exception. In fact, a study published in The Journal of Nutrition found that after just two weeks, those who sipped four to five cups of the green brew each day, in addition to working out for 25 minutes, lost more belly fat than those who didn’t imbibe. Scientists attribute green tea’s ability to shrink waists to the beverages catechins, a type of antioxidant that hinders the storage of belly fat and facilitates rapid weight loss.
Almonds are a great source of mono- and polyunsaturated fats, which can help lower your cholesterol and keep you slim. They also contain fewer calories than most other varieties of nuts (just 163 calories for 23), as well as plenty of fiber and vitamin E. According to a study in the International Journal of Obesity, people who added a daily serving of almonds to a low-calorie diet lost more weight than those who followed the same diet but ate a carb-heavy snack such as crackers instead.
Losing weight isn't all about exercise – what you eat matters too. But nobody wants to eat diet food that makes them feel like they're going to gnaw their arm off before dinner. That's why registered dietitians say it's important to up your intake of veggies, grains, nuts, and other foods that are full of fiber, protein, and other pound-dropping nutrients. These options will help you prevent cravings and keep you full straight through your usual afternoon snack.
