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
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.
When it comes to eating for weight loss, fiber is the number one nutrient that belongs on your radar. The Cleveland Clinic says women should aim for the recommended 25 to 30 grams per day, and one of the easiest ways to do that is by loading your plate with broccoli. The veggie contains 16 grams per bunch! If you don't like eating it solo, sneak it into the dishes you already love, like this Fusilli with Broccoli Pesto recipe.
Eggs are rich in high-quality protein, fats and essential nutrients, like vitamin D and choline. It's the protein, and the time of day we tend to eat them, that especially makes them a powerhouse for weight loss. Eating a high-protein breakfast promotes weight loss, because protein increases satiety while regulating hunger and appetite hormones, helping fend off your hunger until lunchtime. One study found that eating eggs for breakfast left people feeling more satisfied than those who had bagels—which helped them eat less throughout the day.
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.

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.
Gluten, a mixture of proteins found in wheat and related grains including barley, rye, oat, and all their species and hybrids (such as spelt, kamut, and triticale), causes health problems for those with gluten-related disorders, including celiac disease, non-celiac gluten sensitivity, gluten ataxia, dermatitis herpetiformis, and wheat allergy. In these people, the gluten-free diet is the only available treatment.
If you want to sip your way to a faster metabolism, pour yourself a cup of green tea. The beverage is filled with powerful antioxidants that can help fight inflammation, burn fat, and increase energy. According to one study, drinking five cups a day could help you lose twice as much weight, mainly in your midsection. And drinking green tea could also reduce risk of Parkinson's disease, as well as ovarian, colorectal, skin, and prostate cancers.
At least half your grains should be whole grains, such as whole wheat, oats, barley, or brown rice. Whole grains retain the bran and germ and thus all (or nearly all) of the nutrients and fiber of the grain. One sure way of finding whole grains is to look for a product labeled “100% whole wheat” or “100%" of some other whole grain. You can also look for a whole grain listed as the first ingredient, though there still may be lots of refined wheat in the product. Another option is to look for the voluntary “Whole Grain Stamp” from the Whole Grains Council. Or try this tip: Look for less than a 10-to-1 ratio of “total carbohydrates” to “fiber” on the nutrition label.
