Plus, a 2013 study from the University of California, Berkeley suggests that skipping sleep makes your brain's reward zone react to fatty and sugary treats way more enthusiastically. What's more, a study published in the Journal of Clinical Nutrition found that people who didn't get enough sleep ate an average of 385 extra calories that day. In short, more sleep = less calories in your mouth and less fat on your body.  
REALITY: Fat doesn’t make you fat—consuming too many calories does. Foods that contain fat are part of a healthy diet, help maintain your lean body mass, and assist with metabolic function. Healthy fats, like omega-3 fatty acids, can be found in extra-virgin olive oil, coconut oil, almonds, avocados, cashews, peanuts, walnuts, flaxseeds, and more. If you want to lose fat, you need to eat fewer calories and/or burn more calories.
Routinely squeaking by on five hours or less per night increases visceral fat levels, according to a 2010 Wake Forest University study. What’s more, after analyzing 28 different studies, UK researchers found that people who slept 5.5 hours or less per night ate an extra 385 calories the day after compared to those who snoozed for at least 7 to 12 hours. On top of that, they preferred to munch on fatty foods full of empty calories, like chips.
We often make the wrong trade-offs. Many of us make the mistake of swapping fat for the empty calories of sugar and refined carbohydrates. Instead of eating whole-fat yoghurt, for example, we eat low- or no-fat versions that are packed with sugar to make up for the loss of taste. Or we swap our fatty breakfast bacon for a muffin or donut that causes rapid spikes in blood sugar.

"With all the different tips out there, it can be tricky to understand exactly which exercises work the best. HIIT is great for fat burning and will get your heart rate up, but I’d also recommend including strength (resistance) exercises too. Try lifting weights, using resistance bands or using the weight machines at the gym as these will increase your metabolism to help with weight loss, and increase your muscle strength. It’s important to mix-up your whole-body workouts so you don’t get bored."
Keeping a toothbrush handy can do more than polish up that smile (and counter the effects of all that belly-slimming garlic); brushing your teeth throughout the day can also help you ditch that belly fat fast. A study conducted a sample of over 14,000 participants found that brushing after every meal was linked to lower weight. That minty toothpaste flavor not only clashes with virtually every food, brushing may also trigger a Pavlovian response that tells your brain the kitchen’s closed.
Although insulin in anti-lypolytic, meaning it blunts fat burning, the goal post training is to spike insulin levels for the sake of muscle growth. The best way to cause an insulin spike is by using high glycemic carbs such as dextrose, glucose, or maltodextrin. These carbs cause a rapid rise in blood sugar and will therefore cause the greatest insulin response.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
