The total fertility rate (TFR) - the average number of children born to a woman over her lifetime — differs significantly between different regions of the world. In 2016, the highest estimated TFR was in Niger (6.62 children born per woman) and the lowest in Singapore (0.82 children/woman).[69] While most Sub-Saharan African countries have a high TFR, which creates problems due to lack of resources and contributes to overpopulation, most Western countries currently experience a sub replacement fertility rate which may lead to population ageing and population decline.
All in all, the findings suggest that the search for optimized health and nutrition — with all of its calorie counting and macronutrient obsessing — may be making things more complicated than its needs to be. “For literal decades, we have been squandering years from lives and lives from years for failure to use what we truly do know,” Katz says. “It’s tragic that we’ve let it lie fallow all this time.”

Take two high-powered diets—Mediterranean and DASH—and combine them for brain-boosting power. That's the idea behind MIND, a plan designed to help prevent Alzheimer's disease by focusing on foods like green leafy vegetables, whole grains, olive oil, and (hooray!) wine. That's why U.S. News & World Report just ranked MIND as the second best diet overall (tied with the TLC diet). They note that early research found MIND reduced Alzheimer's risk by as much as 53 percent.
Cancer, a very common and sometimes fatal cause of unexplained (idiopathic) weight loss. About one-third of unintentional weight loss cases are secondary to malignancy. Cancers to suspect in patients with unexplained weight loss include gastrointestinal, prostate, hepatobiliary (hepatocellular carcinoma, pancreatic cancer), ovarian, hematologic or lung malignancies.
With the proliferation of macronutrient-based diets over the past several decades, from low-fat to low-carbohydrate, discussion of the three main macronutrients – carbohydrates, proteins, and fats – has become standard when talking about optimal diets. Researchers have begun comparing these “macronutrient management”-style diets to one another in order to determine which is most effective, but thus far evidence is largely inconclusive.
Souping is the new juice cleanse, and for good reason: "Soup is a fabulous food. It's hydrating and fills up your stomach, so eating it before a meal can curb your appetite," says Taub-Dix. In fact, research shows that a soup appetizer can reduce the number of calories you eat at a meal by 20 percent. That said, there's no reason to consume only soup. (You're not going to eat only soup for the rest of your life, right?) Instead, make it an addition to your diet and you'll reap the benefits. This recipe may even help you live to 100.
In the first study, one group of people drastically reduced their intake of carbohydrates, while the other slashed fat intake. But aside from that, the entire study group followed, by and large, the same advice. Everyone was told to limit added sugars, refined flours and trans fats, while eating more vegetables and nutrient-dense foods. They also got identical guidance about healthy lifestyle habits, like sitting down to eat and cooking at home.
When it came onto the scene, it was revolutionary and totally rule-breaking. Eat all the meaty goodness you want—as long as you drastically cut carbs. And in a study on young, overweight and obese women, Atkins beat out higher-carb plans, when dieters shed over 10 pounds in a year compared to less than five in other diets And, nope, Atkins didn't clog their arteries either. Of course, while it's effective for weight loss, low carb diets can be unbalanced if you eat too much meat and too few veggies. Think about if it fits your lifestyle—and don't give up on the other components of a healthy diet—before hopping on the carb-cutting bandwagon.
This fizzy, pleasantly puckery fermented beverage is made by adding a probiotic-rich bacteria to lightly sweetened tea. More and more research is looking into gut health and how it relates to obesity and weight, finding that the millions of bacteria that live in our guts may play a large role by altering the way we store fat, how we balance blood sugar and how we respond to the hormones that make us feel hungry and full. Fueling our gut with beverages and foods that stimulate good bacteria may make losing weight easier than we ever thought possible. Kombucha is readily available in most supermarkets and comes loaded with probiotics — just be sure to look for brands with less than 5 grams sugar per serving.
Interested in following a more historical approach to eating? The Primal Blueprint is similar to the Paleo diet, which has roots in how our long-ago ancestors supposedly ate. This plan ditches grain, sugars, and processed foods while focusing on clean eating with plenty of protein (both animal- and plant-based), lots of vegetables, fruits, and healthy fats. The Primal Blueprint acknowledges other health factors too, advocating for lots of low-intensity activity, some high-intensity exercise, strength training, and plenty of sleep.
Hear us out here: Diets can be restrictive, and you’re less likely to stick with one if you feel like you’re depriving yourself. While Cording swears that water is the absolute best thing you can drink for weight loss, she says it’s also helpful to incorporate one non-water beverage into your repertoire a day so you don’t feel like you’re missing out. That might be kombucha, a cocktail, or a latte—it’s your choice. “It seems to be a more manageable approach than saying you should just drink water,” she says.

The formation is peculiar to English and Dutch. Replaced older Old English wif and quean as the word for "female human being." The pronunciation of the singular altered in Middle English by the rounding influence of -w-; the plural retains the original vowel. Meaning "wife," now largely restricted to U.S. dialectal use, is attested from mid-15c. Women's liberation is attested from 1966; women's rights is from 1840, with an isolated example in 1630s.
