During early fetal development, embryos of both sexes appear gender-neutral. As in cases without two sexes, such as species that reproduce asexually, the gender-neutral appearance is closer to female than to male. A fetus usually develops into a male if it is exposed to a significant amount of testosterone (typically because the fetus has a Y chromosome from the father). Otherwise, the fetus usually develops into a female, typically when the fetus has an X chromosome from the father, but also when the father contributed neither an X nor Y chromosome. Later at puberty, estrogen feminizes a young woman, giving her adult sexual characteristics.
Particular religious doctrines have specific stipulations relating to gender roles, social and private interaction between the sexes, appropriate dressing attire for women, and various other issues affecting women and their position in society. In many countries, these religious teachings influence the criminal law, or the family law of those jurisdictions (see Sharia law, for example). The relation between religion, law and gender equality has been discussed by international organizations.

Every time you chug a bottle of soda, you get hundreds of empty calories. Switching to diet soft drinks is an obvious way to cut calories, but the research is mixed on whether this switch leads to weight loss. Some studies show a short-term benefit. Others find diet soda drinkers gain weight. If you eat or drink more calories than you burn, just switching to diet soda may not do the trick.
2. (tie) Jenny Craig, Biggest Loser, and Raw Food diets (3.5 stars): The Biggest Loser plan, from the TV show, is built around healthy food and regular exercise. Jenny Craig provides weekly one-on-one counseling sessions and has prepackaged, portion-controlled foods. The Raw Food Diet was cited for both short-term and long-term weight loss. Raw foods typically have fewer calories than other foods. The restrictive diet may not work for everyone, experts caution.
When it comes to the "best" diet for most people, this one consistently ranks at the top of every list. If you can't afford a cruise to the Mediterranean (yet!), at least you can eat like the beautiful, long-living, and famously healthy people from the region. The Mediterranean diet teaches you to eat like a Sardinian, one of the "blue zones" identified by researchers as having a high number of people living past 100—by eating more fish, olive oil, healthy fats, and fresh vegetables. The point is to have not just a longer life but also a healthier and happier one, whether you're trying to lose weight or not. (Really—research shows that you can reap the benefits of the Mediterranean diet without cutting calories.)
It’s easy to see the front of a package and get lured in by misleading claims, particularly those that say they’re “free-from” something, says Taub-Dix. She points out that gluten-free foods may also be high in sugar, salt, calories, and fat and contain less fiber—and thus be weight-promoting. Reading the nutrition label will give you the real truth for what you’re buying.
