Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.

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.

The good news is that there’s increasing evidence that the brain can, in large part, “fix” itself once new behavior patterns emerge (i.e., calorie restriction, healthy food choices, and exercise). While there may be some degree of “damage” to the brain, particularly in how hunger and satiety hormones function, it can correct itself to a large degree over time. The key is that the process does take time, and like any other behavior change, is ultimately a practice. “We want to change behavior here,” says Hill. “Anyone that tells you it’s going to happen in 12 weeks, that’s bogus. We’re trying to rewire the brain. Neurobiology has told us so much about what’s going on in weight gain and weight loss. It takes a long time to develop new habits, rituals, routines. This takes months and years. But it will happen.”
“It seems so simple, but 45 to 60 minutes of brisk walking every day can do wonders for your metabolism,” Sahmura Gonzalez, a master trainer at Crunch Fitness in New York City, recently told Prevention. “Plus, it ensures that you don’t over-train, which can lead to an over-production of cortisol—a stress hormone that’s been shown to contribute to belly fat.”
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
