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.
Know your why: “When you set a goal, write down why that goal is important to you. Because when you mess up — and you will — you can go back and read what you wrote and why it was meaningful and that will make you remember why you started," says Delaney. "When you fail — because everyone will fail at some point — go back to the book and remember why you set the goal in the first place.”
Why does this popular plan work? For one thing, it pushes wildly healthy staples to the forefront (think: nuts, vegetables, fruit, olive oil). For another, it's simply delicious, thanks to it's focus on fresh, simply prepared dishes like grilled fish with lemon and whole wheat pita with hummus. Science agrees: One meta-review of 16 studies, found the eating M.O. helped those on it lose an average of 8.5 pounds.
The Biggest Loser program has come under attack with recent revelations that its amazing, as-seen-on-TV results are both pharmaceutically assisted and likely to reverse. Living proof that the medical community’s understanding of weight loss is still evolving: The diet still stands in third place on US News’ & World Report’s list for Best Fast Weight Loss.
Processed, packaged foods are often loaded with more salt, sugar, and refined carbs than you’d put in the foods you cook for yourself. When you’re looking to drop weight fast, avoid foods that come in packages and stick to whole, unprocessed foods. (Here are the four most harmful ingredients in processed food.) Build your plates with non-starchy veggies, unprocessed whole grains, lean proteins, and healthy fats, and season with spices, not salt.
There's a pretty dizzying amount of research backing up this regime as a solid option to enhance your health, lower cholesterol, and encourage healthy, lasting weight loss. DASH (the acronym stands for Dietary Approaches to Stop Hypertension) has you loading up on fruits, vegetables, and whole grains (surprise!) and removing foods high in saturated fat from your diet. Research also shows that this diet may even ward off the onset of type 2 diabetes.
“Anytime you’re stressed, you probably go for food,” Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
While the American College of Sports Medicine warns that women who eat less than 1,300 calories a day and men who eat less than 1,800 risk slowing down their metabolism over time. But a rev-up stage that only lasts two weeks is approved by doctors and isn’t as difficult as it seems. Our tester found the Mayo Clinic day pretty satisfying, and still had enough energy to hit the gym.
Measure it: If you want to improve something, measure it. While a pedometer can seem utterly arbitrary, wearing one and holding yourself to a daily goal can lead to forming powerful habits. Fitbit devices also allow you to create an online account where you can track yourself against friends and co-workers, so you can push each other to exercise. The nice thing about measuring exercise rather than weight is one can become a habit that leads to the desired goal, whereas the other is a lagging and fluctuating indicator. Each day you do your daily exercise you will be aware of what you did and how it made you feel. And those who exercise may have slightly elevated serotonin levels which lead to improved satiety, diminishing hunger.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Weight loss may help chase your blues away. Scientists are still trying to work out why, but better body image and improved sleep may be part of the reason. In one study, depressed people who were very overweight felt better after they lost an average of 8% of their body weight. Other research shows you’ll continue to feel better, even after 2 years -- as long as you keep the weight off.
