A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
In general, healthy eating ingredients are found around the outer edges of most grocery stores, while the center aisles are filled with processed and packaged foods that aren’t good for you. Shop the perimeter of the store for most of your groceries (fresh fruits and vegetables, fish and poultry, whole grain breads and dairy products), add a few things from the freezer section (frozen fruits and vegetables), and visit the aisles for spices, oils, and whole grains (like rolled oats, brown rice, whole wheat pasta).
“Pistachios are a great addition to a diet aimed to help one lose weight because they're one of the lowest-fat and lowest-calorie snacks that offer the most nuts per serving (49 pistachios per 1-ounce serving) compared to cashews (18) and walnuts (14 halves),” says Shaw. Get in-shell pistachios because the leftover shells may provide a visual cue for portion control to curb intake.
^ Biesiekierski JR (2017). "What is gluten?". J Gastroenterol Hepatol (Review). 32 Suppl 1: 78–81. doi:10.1111/jgh.13703. PMID 28244676. Similar proteins to the gliadin found in wheat exist as secalin in rye, hordein in barley, and avenins in oats and are collectively referred to as “gluten.” Derivatives of these grains such as triticale and malt and other ancient wheat varieties such as spelt and kamut also contain gluten. The gluten found in all of these grains has been identified as the component capable of triggering the immune-mediated disorder, coeliac disease.
The saturated fats in animal foods generally boost levels of LDL (“bad”) cholesterol and have other adverse effects. To limit your intake, choose lean meats, skinless poultry, and nonfat or low-fat dairy products. It’s also a good idea to replace saturated fats with unsaturated fats (see next slide). Keep in mind, though, that not all saturated fats are bad for you; those in chocolate, milk, and cheese, for example, are more neutral in their effect on blood cholesterol. Trans fats from partially hydrogenated oils are even worse than saturated fats, but FDA regulations have now nearly phased them out of the food supply.
Fruit gets a bad rap sometimes because it naturally contains sugar. But eating fruit can help you lose weight, especially when you swap in fresh fruit for processed foods or other unhealthy snacks. You'll get a naturally sweet treat, plus reap the benefits of fiber and antioxidants. A recent study published in the Journal of Nutrition found that higher fruit consumption was associated with lower risk of becoming overweight or obese, independent of vegetable or fiber intake—though including fruit as part of a healthy diet overall is always the best strategy.
While no one food is a magic bullet for weight loss, there are certain foods that can help you achieve your weight-loss goals. Most of the foods included as part of a weight-loss diet have a few things in common: they're high in fiber (which helps keep you feeling fuller longer) and have a low energy density—meaning that you can eat a decent-sized portion without overdoing it on calories. Include the following weight-loss foods as part of a healthy overall diet, and you may find it's easier to achieve your weight-loss goals.
A big reason to incorporate more strawberries into your diet: not only do they taste delicious, but a study from Harvard Medical School found that an increased intake of flavonoid-rich fruits, like strawberries, could help prevent weight gain. Stock up on the seasonal fruit in summer, but don't shy away from grabbing the frozen variety once colder temps hit — fruit is frozen at its nutrient peak, so you'll still nab most of the same health benefits.
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
These support bone health and have other possible benefits. Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
