Fears of high cholesterol were frequently voiced up until the mid-1990s. However, more recent research has shown that the distinction between high- and low-density lipoprotein ('good' and 'bad' cholesterol, respectively) must be addressed when speaking of the potential ill effects of cholesterol. Different types of dietary fat have different effects on blood levels of cholesterol. For example, polyunsaturated fats tend to decrease both types of cholesterol; monounsaturated fats tend to lower LDL and raise HDL; saturated fats tend to either raise HDL, or raise both HDL and LDL; and trans fat tend to raise LDL and lower HDL.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
For people who are healthy, a healthy diet is not complicated and contains mostly fruits, vegetables, and whole grains, and includes little to no processed food and sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although a non-animal source of vitamin B12 is needed for those following a vegan diet. Various nutrition guides are published by medical and governmental institutions to educate individuals on what they should be eating to be healthy. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health.
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.
As long as you don't go nuts on nuts (which can be calorie overload), they can be super beneficial in helping you lose weight. In a study published in the European Journal of Nutrition, researchers found that those who got their protein from nuts instead of animal products had less weight gain than those who never ate them. So consider this your permission to snack on peanuts, almonds, hazelnuts, pistachios, and walnuts — so long as you practice portion control. If sodium is a concern, grab roasted or raw over salted varieties.
Long live the sweet potato, savior to all people looking to cut back on carbohydrates in a healthy way. "Carbohydrates are your body's preferred source of energy," Abbey Sharp, R.D. with Abbey’s Kitchen, told SELF in a previous article. "Enjoying more fiber-rich complex carbs like whole grains, fruits, and vegetables will be more conducive to weight loss and health in general than eating refined ones, which can spike blood sugar quickly." That’s where sweet potato comes in, serving up 41 grams of healthy carbs and 7 grams of fiber (keep the skin on!) per cup.
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.
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.
That means one drink a day for women, two a day for men. People over 65 should drink even less. A drink is defined as 12 ounces of beer, 5 ounces of wine, or 1½ ounces of 80-proof spirits. While alcohol has potential heart benefits, it poses a variety of health risks, especially in excess amounts. And some people shouldn't drink at all, including pregnant women and those taking medications that interact with alcohol. People with liver disease, high trigylcerides, sleep apnea, and certain other conditions should ask their doctors about the advisability of drinking.
Good news for java lovers: The caffeine in coffee could speed up your metabolism and help your body burn slightly more calories (about 26 per cup). A study in Physiology & Behavior found that the average metabolic rate of people who drank caffeinated coffee was 16% higher than those who drank only decaf. Just be mindful of how much cream and sugar you add to your cup, which could offset any health benefits the beverage provides.
If you’re on a quest to jumpstart weight loss, why not kick your metabolism into overdrive by sneaking spicy foods into your diet. Capsaicin, the active ingredient in cayenne pepper that gives it its spiciness, revs up your metabolism in a way that’s conducive to weight loss. In fact, according to a study in the American Journal of Clinical Nutrition, those who supplemented their diet with capsaicin consumed 200 fewer calories during their next meal.
What if we told you that you could make 20 percent of your belly disappear this year—poof, just gone? Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend. Those on the canola oil diet—just three tablespoons daily did the trick—lost nearly 2 percent of their belly fat in just one month. For more ways to enjoy big, bold flavors, burn flab with these healthy fats.
Serve up this plant-based feast in just 20 minutes. Using a food processor will have your patties ready in a snap. Cremini mushrooms, often called baby bellas, are what give the burgers their meaty texture and earthy flavor—opt for these over milder button mushrooms. Ground flaxseeds add body and texture to these burgers. The cool and creamy yogurt and avocado mixture is a great go-to spread; slather it inside pita pockets or on your morning toast.
You likely don’t pay much mind to sesame seeds, but research shows that the crunchy little buggers may play a crucial role in weight maintenance. So, you should seriously consider tossing them into a salad or whole wheat noodle dish. Researchers suspect its the lignans—plant compounds—found in sesame seeds (and flax seeds) that makes them so special. In a 2015 study, women who consumed high levels of lignans tended to weigh less and gain less weight over time when compared to women who didn’t consume these compounds in high amounts.

Challenge yourself to come up with two or three dinners that can be put together without going to the store—utilizing things in your pantry, freezer, and spice rack. A delicious dinner of whole grain pasta with a quick tomato sauce or a quick and easy black bean quesadilla on a whole wheat flour tortilla (among endless other recipes) could act as your go-to meal when you are just too busy to shop or cook.
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.
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.

These include soda, candy, white bread, regular pasta, and many snack foods and baked goods. A high intake of added sugar increases inflammation and insulin resistance, increasing the risk of diabetes, cardiovascular disease, and other disorders—and it supplies “empty” calories that contribute to weight gain. Refined grain products have little dietary fiber and have been stripped of many nutrients; a high intake can cause many of the same health problems as added sugar.
Fruit and vegetables are low in calories and nutrient dense, which means they are packed with vitamins, minerals, antioxidants, and fiber. Focus on eating the recommended daily amount of at least five servings of fruit and vegetables and it will naturally fill you up and help you cut back on unhealthy foods. A serving is half a cup of raw fruit or veg or a small apple or banana, for example. Most of us need to double the amount we currently eat.
