As funny as it sounds, sleep deprivation may make you fat — and not just because you're susceptible to cases of the late-night munchies (although there's that too). There's tons of research that demonstrates getting less than the desired amount — about 7 hours — of sleep per night can slow down your metabolism. Plus, when you're awake for longer, you're naturally more likely to nosh. So don't skimp on your ZZZs, and you'll be rewarded with an extra edge when it comes to shedding pounds quickly.


Sugar contains calories but nothing else, and "empty calories" are the last thing you want on a diet, says Stephanie Karpinske, MBA, M.S., R.D. Sugar is also digested quickly so you're hungry soon after you eat it. It raises insulin levels, which promotes fat storage. Plus, it can be addictive because it raises levels of serotonin -- the feel-good chemical in the brain that helps us relax during times of stress. That's one reason why weaning yourself off sugar is so difficult.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
Your New Year's resolution diet should be based on a well-balanced eating plan that fits your lifestyle, rather than a weird fad replete with food restrictions. That's according to U.S. News & World Report's best diet rankings for 2018. The two diets that tied for the top spot -- the Mediterranean Diet and the DASH Diet -- fit that bill because they feature real food and reasonable, flexible guidelines, experts said.
We know that shedding unwanted pounds used to mean giving up your favorite foods, logging hours at the gym, and being hungry (and hangry) all the time. Fortunately, dropping a dress size (or two) doesn’t have to be that complicated or torturous. Sure, losing any significant amount of weight requires lifestyle changes and some hard work, but it all boils down to simple choices.

Chronic stress may increase levels of stress hormones such as cortisol in your body. This can cause increased hunger and result in weight gain. If you’re looking to lose weight, you should review possible ways to decrease or better handle excessive stress in your life. Although this often demands substantial changes, even altering small things – such as posture – may immediately affect your stress hormone levels, and perhaps your weight.


A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
Nearly 30% of U.S. adults say they're trying to go gluten free—but unless you've been diagnosed with celiac disease, there's really no need. In fact, cutting all gluten foods (such as wheat, barley, and rye) from your diet won't necessarily help you lose weight. Gluten-free junk foods are everywhere, and a gluten-free cookie or slice of pizza is just as bad for you as the regular kind.
We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.

Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, "people who try to stop eating after 7pm can’t do it every day for the rest of their lives," says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.
Sure, there's your one friend who swears by the Taco Cleanse. And that other friend who ate nothing but broccoli soup for a month and dropped 20 pounds, found the love of her life, and got promoted at work. But before you start blending 80 stalks of broccoli into a cup or crunching your way through a crate of tacos, check out which diets are backed by science. Because don't you want to try one that will do the trick for you?
