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.
Speaking of standout breakfast foods, Greek yogurt is another option worthy of the spotlight thanks to its high-protein content. Per study in the journal Appetite, researchers from the University of Missouri compared the satiety effects of high-, moderate-, and low-protein yogurts on women aged 24-28, and found Greek yogurt, with the highest protein content, to have the greatest effect. What’s more? Probiotics in items such as yogurt and fermented foods, like pickles and sauerkraut, help good bacteria in the gut process food more efficiently. Hello, weight loss! If you want to get even more protein in your yogurt, check out Icelandic yogurts, which can have two to three more grams of protein per serving compared to Greek.
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.
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
The nutritional content of this tasty spread may freak you out, but there's no reason to be afraid of fat! Fat helps make food taste delicious and keep you satiated, so it's actually good news that 1 tablespoon of almond butter has 9 grams of the stuff. Even better, adding almond butter to a carb-based food can help stave off a blood sugar spike thanks to its fat and protein (2 grams per tablespoon).
Diets to promote weight loss are divided into four categories: low-fat, low-carbohydrate, low-calorie, and very low calorie. A meta-analysis of six randomized controlled trials found no difference between the main diet types (low calorie, low carbohydrate, and low fat), with a 2–4 kilogram weight loss in all studies. At two years, all of the diets in the studies that reduced calories caused equal weight loss regardless of whether changes in fat or carbohydrate consumption were emphasized.
Good news, wine drinkers. Thanks to resveratrol, an antioxidant found in grape skin, drinking red wine in moderation can be part of a healthy diet. Some studies suggest that people who drink wine have smaller waists and less abdominal fat than those who drink mainly liquor. And having one glass of red wine can increase your body's calorie burn for up to 90 minutes afterwards. The antioxidants in wine might even help your body prevent cancer and improve heart health. Just be sure to stick to no more than a glass a day—the calories can add up fast.
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.
All beans are high in fiber, which is your friend when you're trying to lose weight because it helps you feel fuller longer, thus controlling hunger. Eating beans and legumes has also been linked with various other health benefits, including lowering blood pressure, reducing LDL cholesterol and reducing risk of cardiovascular disease. Beans are fairly low in calories and deliver protein as well. Try them in homemade veggie burgers, soups and salads.
Calcium and vitamin C team up well to boost metabolism, and broccoli is just one of several healthy foods that contain both nutrients. What sets broccoli apart from the others, however, is that the green veggie also contains kind of fiber that’s been shown to increase the digestion, absorption and storage of food, also known as the thermic effect of food or TEF. Combine a revved up metabolism with an increased TEF and you get a match made in weight loss heaven!
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.
While we’re on the subject of water, why not throw a few lemon slices into the hydrating and satiating beverage? In addition to adding a pop of color and flavor to a tall glass of H2O, lemon can also help encourage weight loss. Just one of the bright citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of a stress hormone called cortisol that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain.
