Thanks to its flexibility, easy-to-understand system, and group support, Weight Watchers came out way (weigh?) ahead, winning "best weight loss," "best fast weight loss," and "best commercial diet" in the U.S. News & World Report rankings. (Oprah's endorsement probably didn't hurt either!) They recently revamped their signature plan to include "free" foods like chicken breasts and fresh produce so you'll never feel hungry even while dropping pounds. In addition, their app makes tracking your food a piece of cake—which you're totally allowed to have on the program, by the way. (Even better news: Research supports the fact that Weight Watchers is one of the best weight-loss diets.)
Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.
Although fewer females than males are born (the ratio is around 1:1.05), because of a longer life expectancy there are only 81 men aged 60 or over for every 100 women of the same age. Women typically have a longer life expectancy than men. This is due to a combination of factors: genetics (redundant and varied genes present on sex chromosomes in women); sociology (such as the fact that women are not expected in most modern nations to perform military service); health-impacting choices (such as suicide or the use of cigarettes, and alcohol); the presence of the female hormone estrogen, which has a cardioprotective effect in premenopausal women; and the effect of high levels of androgens in men. Out of the total human population in 2015, there were 101.8 men for every 100 women.
The caffeine content in Sambazon’s drink line comes from green tea and guaraná, a a native plant from Brazil with roughly twice the concentration of caffeine found in coffee seeds, and—bonus!—the ability to fight fat and lower cholesterol. A recent study found daily supplementation with guaraná could reduce LDL cholesterol levels in healthy adults by as much as 27 percent! And a second animal study published in Clinical Nutrition found guaraná extract supplementation could increase fat metabolism.
This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight-loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason.

Not so sure about becoming a vegetarian or vegan? That's where the flexitarian diet comes in. You're basically adding new foods into your diet, focusing on plant-based proteins like tofu, beans, nut or soy milk, and eating less meat — but not cutting it out completely. Since vegetarian and vegan diets typically lead to weight loss, you'll see results from being a flexitarian, too: Studies show those who are mostly vegetarian or vegan have a lower BMI than full-on meat-eaters.
If you like the taste of apple cider vinegar, then by all means, drink up! But if you are a normal human being who prefers not to chug pure acid, then you should know there's zero evidence that drinking the nasty stuff can actually help you drop pounds (or impart the laundry list of health benefits the Internet seems to associate with it, for that matter).
Unintentional weight loss may result from loss of body fats, loss of body fluids, muscle atrophy, or even a combination of these. It is generally regarded as a medical problem when at least 10% of a person's body weight has been lost in six months or 5% in the last month. Another criterion used for assessing weight that is too low is the body mass index (BMI). However, even lesser amounts of weight loss can be a cause for serious concern in a frail elderly person.
DASH stands for "dietary approach to stop hypertension" and was created by the National Institutes of Health (NIH) as a way to help reverse national trends of obesity and heart disease. Scientists combed through decades of research to come up with an expert-backed list of diet tips, along with a prescription for exercise. And it worked: The DASH diet has topped nearly every diet list for nearly a decade. Doctors particularly recommend it for people looking to lower high blood pressure, reverse diabetes, and lower their risk of heart disease. (Here's the basic list of DASH diet-approved foods.)
A great pick-me-up for dieters, Bai5 serves up a gentle 35 mg caffeine plus 200 g of antioxidant-rich white tea. A study published in the journal Nutrition and Metabolism showed that white tea may be especially powerful at targeting fat cells, with the ability to simultaneously boost lipolysis (the breakdown of fat) and block adipogenesis (the formation of fat cells) due to high levels of fat-fighting compounds called catechins, belly-fat crusaders that blast adipose tissue by revving the metabolism, increasing the release of fat from fat cells. The folks at Bai tell us their most popular flavors are coconut, blueberry and mango & pomegranate.
How it works: The IIFYM diet lets you eat anything you want and you’ll lose weight as long as you meet your prescribed daily set of macronutrients (carbs, proteins and fats). Calculate your personal macros by figuring out your total daily expenditure, then how many calories you should eat per day to lose weight. From there, you’ll divide the calories into the percentage of calories that should come from fat (20 percent), protein (40 percent) and carbohydrates (40 percent).
White tea is dried naturally, often in sunlight, making it the least processed and richest source of antioxidants among teas (as much as three times as many polyphenols as green tea!). A study published in the journal Nutrition and Metabolism showed that white tea can simultaneously boost lipolysis (the breakdown of fat) and block adipogenesis (the formation of fat cells) due to high levels of ingredients thought to be active on human fat cells. If there’s such a thing as diet tea, this is it. And keep your waistline toned and tight—in record time—with these essential 29 Best-Ever Proteins for Rapid Weight Loss.
An imbalance of maternal hormonal levels and some chemicals (or drugs) may alter the secondary sexual characteristics of fetuses. Most women have the karyotype 46,XX, but around one in a thousand will be 47,XXX, and one in 2500 will be 45,X. This contrasts with the typical male karotype of 46,XY; thus, the X and Y chromosomes are known as female and male, respectively. Because humans inherit mitochondrial DNA only from the mother's ovum, genetic studies of the female line tend to focus on mitochondrial DNA.

Popularized by the documentary Forks Over Knives, the Ornish diet is a low-fat, plant-based diet plan based on whole grains, vegetables, fruits, and legumes. It's based on a lacto-ovo style of vegetarianism, allowing only egg whites and nonfat dairy products. It's packed with vitamins, fiber, and lots of filling plants to keep you satiated. Some studies have shown it can reverse heart disease and have beneficial effects on other chronic health conditions. (BTW, there is a difference between a vegan diet and a plant-based diet.)
