THE ROHIT'S SHOW

You're filling up on healthy foods, exercising daily and still, the scale isn't budging. It's mind-numbingly frustrating. Luckily, it's also fixable. Here are six common things that could be standing between you and your weight-loss goals – plus easy ways to bust through each.

1. You Aren't Tracking What You Eat

"Most of the time, when someone comes into my office saying they aren't losing weight, the problem is that they are eating a lot more than they think they are," says Holly Herrington, a registered dietitian and clinical nutritionist with the Center for Lifestyle Medicine at Northwestern Medical Faculty Foundation. "Almost every single person underestimates how much they are eating." You can blame oversized restaurant portions, mindless munching and "health halos" for that, she says.

After all, French fries and ice cream aren't the only things that are calorie-packed. So are healthy foods, including olive oil, avocado and nuts. For instance, 1 cup of almonds contains about 750 calories. If you're snacking on them (a great idea), but without measuring and tracking those calories (a bad idea), you could easily end up gaining weight, Herrington says.

She recommends tracking everything you eat, at least for a couple months, with apps like My FitnessPal, which will help you learn proper portion sizes and how your favorite health foods measure up calorie-wise. In one American Journal of Preventive Medicine study, people who kept daily food records lost double the weight of those who didn't track their food intake.

2. You're Not Sleeping Enough

A bad night's sleep can wreck your weight-loss efforts through a two-pronged approach. For one, it makes you hungry and likely to overeat. "When you don't get enough sleep, your levels of cortisol and also ghrelin, a hormone that increases the sensation of hunger, rise," explains board-certified internist Dr. Patricia Salber.

For example, in one University of Chicago study, healthy young men who got just four hours of sleep two nights in a row (compared to their usual seven to nine hours) reported a 24 percent increase in appetite, along with cravings for candy, cookies, chips, bread and pasta. They also experienced an 18 percent decrease in leptin, which promotes fullness, and a 28 percent increase in the hunger-hormone ghrelin.

Second of all, not getting enough sleep could make your body store what you do eat as fat. For instance, a 2011 study in the American Journal of Clinical Nutrition found that just one night's bad sleep caused healthy men's resting energy expenditure – the number of calories they burned by simply being alive – to drop by 5 percent. The number of calories they burned after each meal also dropped by 20 percent.

"Sleep deprivation and sleep apnea may affect blood sugar levels and increase insulin resistance," says endocrinologist Dr. Michael Bergman, clinical professor of medicine at the NYU Langone Medical Center. "Sleep disorders, namely obstructive sleep apnea, [have] been associated with the development of Type 2 diabetes."

If clean-sleep habits – such as keeping your bedtimes consistent and not playing on electric devices in the hour before bed – don't help you get eight solid hours a night, talk to your doctor about how you can sleep better and longer, he says.

3. You're Eating the Same Number of Calories You Did on Day One of Your Diet

Oh, the weight-loss plateau: At the beginning of your diet, you were losing weight and feeling great. But now, you're doing the exact same thing, but with zero results. That might be the problem. "As you lose weight, your caloric needs will change," Herrington says. "The smaller you get, the fewer calories your body needs, so the fewer calories you'll need to eat to continue losing weight."

If your weight-loss results have plateaued for one to two months, she recommends gradually cutting back on calories. Start by eating 100 fewer calories a day and see how the scale shifts in a couple weeks' time. Don't cut back too much, though. Most women shouldn't eat any fewer than 1,200 calories a day and men shouldn't eat any fewer that 1,700 a day. Meanwhile, you should never feel famished or low on energy, she says.

4. You're Constantly Stressed

Acute stress – say from a looming work deadline or relationship drama – can cause your appetite to go MIA. But if the stress keeps up and becomes chronic, too-high levels of the stress hormone cortisol can increase your appetite, particularly for high-carbohydrate foods, according to Salber.

"When stressed, people seek to comfort themselves and relieve the tension," she says. "All too often, that means turning to sugar or starchy foods." High-carb foods can cause a quick spike in blood sugar and feel-good serotonin levels. But both crash quickly, and put you in a vicious cycle of stress and overeating.

Meanwhile, by stimulating the production of insulin, cortisol also increases your body's tendency to store calories as visceral fat. A type of fat that hangs out in the abdominal cavity and likes to hug your vital organs, visceral fat is associated with the development of insulin resistance and, in some cases, diabetes, Salber says.

If you can't remember the last time you weren't stressed, consider visiting your doctor or a therapist to help you manage your stress levels and get healthy. Mental health issues, including stress, are no different than physical health issues, she says. They deserve professional help.

5. You're Using Artificial Sweeteners

Artificial sweeteners, whether you stir them into your coffee, get them from diet sodas or spoon them from your yogurt container, are an easy way to cut calories and sugar in the short term, but they could harm your long-term weight-loss efforts. Case in point: Research from the University of Texas found that over the course of 9.5 years, the average two-a-day diet-soda drinker puts on five times more belly fat than do people who abstain.

That could be because your brain responds to artificial sweeteners by telling you to eat more sweet stuff, according to the Harvard School of Public Health. Meanwhile, they may also throw off the balance of healthy bacteria in the gut, Salber says.

A 2014 study from the Israel-based Weizmann Institute of Science's immunology department found a significant correlation between the consumption of artificial sweeteners, gut bacterial configuration and a tendency to develop glucose intolerance, which contributes to the development of obesity and Type 2 diabetes.

Eliminate any artificial sweeteners in your diet and replace them with sweeteners that also contain vitamins and minerals, such as honey and maple syrup. Just make sure to count their calories.

6. You Have a Medical Condition

While rare, underlying health conditions can make weight-loss difficult to achieve on your own. For instance, Cushing's disease, marked by excess cortisol levels, and polycystic ovary syndrome, a common endocrine disorder in women, can both contribute to glucose disorders, Bergman says.

Meanwhile, hypothyroidism, a condition in which the thyroid gland doesn't produce enough hormones, can also contribute to weight-management issues. About half of thyroid disorder cases in America are undiagnosed, according to the American Association of Clinical Endocrinologists.

If you aren't losing weight, but feel like you are following your body's caloric needs and are exercising between two and five hours a week, Herrington recommends talking to your doctor about your weight-loss concerns. He or she may be able to run some simple tests to make sure a health condition isn't behind your frustrations. If something is amiss, treating it will do more than help you lose weight.

Facebook just showed a bunch of mind-bending optical illusions to prove virtual reality is reality

In a presentation on day two of Facebook's F8 conference in San Francisco, Oculus Chief Scientist Mike Abrash talked about how virtual reality can hack our brains and completely shake up our basic humanity.

"Your visual system is reverse-engineering reality," Abrash said.

Our brains just interpret what we see, but they lie to use all the time. Abrash quoted Morpheus's famous "red Pill" monologue from The Matrix, saying that reality is only a series of electrical signals interpreted by the brain.

To prove it, he demonstrated a bunch of common optical illusions, starting with The Dress (it's black and blue, for the record) and eventually getting to more complex ones like a Matrix-inspired one with those red and blue pills:

(Spoiler: They're both actually the same shade of grey. The background makes them look different.)

Similarly, he showed shapes that looked to be different sizes but were actually the same size:

Shapes that couldn't possibly exist, but do. And so on.

"You're making a very reasonable assumption about the world that happens to be wrong," Abrash said.

The takeaway: Your brain is malleable, reality is a lie, and Oculus Rift can take advantage of that to trick you into thinking you are where you're not. After all, a virtual reality headset is just blasting your eyeballs with photons really quickly, and it can take advantage of all of those things.

"Virtual reality, done right, really is reality, as far as the observer is concerned," Abrash said.

As far as the future goes, Abrash says that there's a ton of potential for integrating hands with virtual reality to improve your sense of place, and maybe even simulating the sense of touch. He also wants to let you scan real environments and real objects like your room and your coffee cup and bring them into virtual reality.

Visual quality and audio are also priorities for improvement within Oculus, Abrash said. The competition (implied but not named, like HTC Vive and Sony Project Morpheus) is going to push virtual reality forward, with technology improving rapidly as the market accelerates.

But the vast majority of Abrash's presentation was given over to how Oculus Rift can make the unreal very real by tricking your mind.

Incidentally, those pictures were shown on stage, but Facebook also handed out an envelope with physical versions. Here's what the envelope said:
