"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."
”In many ways, body fat is the same as food intake, it’s all available energy, and this is reflected in the fact that adipose tissue produces leptin. You can increase fat by 10-20g, and that’s another 90-180 calories your body “sees”, but gain 1lb of body fat and you’ve got 3500kcals that your body is seeing now…so yeah, changes in body fat can make much larger impacts than what you consume…that’s why I shake my head when guys freak out about going from 50g to 45g of dietary fat….really, you think the 45 calories per day is what is going to kill your libido, not the fact that you lost 10lbs (35,000kcals) of fat? ”

This formula will help you lose weight faster, says Kristin Kirkpatrick, R.D., manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. A 2016 study published in the American Journal of Clinical Nutrition suggests that increasing your protein intake while decreasing the amount of calories you consume ensures that you lose fat instead of muscle. This 35-35-30 breakdown doesn't mean you can eat any old carb or fat though, she says. Aim to get most of your healthy fat from nuts and fish, your carbs from beans and whole grains, and protein from lean sources like eggs, chicken, and fish, she says.


Who wrote this no Arthur or Scientific Studys shown. Just a bunch of bro science. Fasted cardio is fine if your doing Low Intensity Steady State Cardio. If your using l-carnitine to transport fat and other fat burners they will be more effective on empty stomach. Ya if your doing HIIT cardio on empty stomach it needs quick energy which will pull aminos instead fat which take longer to get.
People often think that low-intensity exercise, in which your body taps into fat metabolism, is the most efficient way to lose body fat. Some cardio machine displays even claim that you’re in the fat-burning zone when your heart rate is low and that you exit the zone once your heart rate rises. Physiologically, the second part of that statement isn't true. 
Since only two HIIT sessions should be performed per week another type of cardio will be needed for the rest of the cardio sessions throughout the week. MISS (Moderate Intensity Steady State) cardio is the perfect type of cardio to fill in any remaining cardio that needs to be performed during the week. This will burn a great amount of calories while sacrificing very little muscle tissue and burning fat through different pathways from the HIIT.
A study in the April 1999 issue of the Journal of the American College of Nutrition proved the calorie-burning benefits of muscle. The study put two groups of obese individuals on a very low-calorie diet. One group did only aerobic exercises four times per week while the other group did only resistance exercises three times per week. After 12 weeks, the aerobics group lost more weight than the resistance group. However, in the aerobics group almost one third of the weight lost was muscle. The resistance group lost only fat.
Every expert ever will tell you that crash diets don’t work, are unhealthy, and offer at best a temporary fix since you may end up gaining back more than you initially lost once you fall off the wagon. But that doesn’t mean losing weight has to be a slow, torturous process either. Yes, you’ll still have to eat few calories than you burn, but nutrition and exercise researchers have uncovered some scientifically tested ways to make that easier and faster than ever.
Soup -- we're talking broth-based, not creamy -- has a lot going for it. It's full of water, which fills you up with the fewest possible calories. It's hot, which prevents you from eating too much. Have it before a meal, and soup can take up space that might have gone to higher-calorie foods. You can also make a satisfying, low-calorie meal out of soup alone by adding chicken, fish, cut-up vegetables, or beans.
But don’t lose hope just yet. You can still incorporate strategies that help you lose total body fat, which will benefit your belly. At the end of the day, nothing sheds belly fat like diet, exercise, and everyday changes to your lifestyle. The slimmer stomach of your dreams is always within reach, but it takes time and dedication. Commit to these habits, and you’ll start dropping pounds before you know it.
1. High Intensity Interval Training (HIIT): This type of exercise is your key to melting belly fat fast.  HIIT is highly effective for all over weight loss, particularly removing stubborn belly fat. If you are not eating right, you have reached menopause or you are not losing weight you should do these exercises. Don’t let the name scare you as it is you who determines the intensity.  It is your perceived exertion that counts.
If you get enough protein and fat, your total calorie intake should take care of itself. Because you feel full, you won't binge on a can of Pringles and blow your calorie count for the day. The remaining 45 percent of calories in our plan comes from carbohydrates — enough to give your palate a full range of tastes and your body a combination of fast- and slow-burning fuel.
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.  
Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you’re eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with the 20 Healthy Fats to Make You Thin.

Another misconception about HIIT is that it will cause muscle loss. This is just not true either. This myth got started because a higher amount of calories burned during HIIT will come from stored amino acids (muscle tissue) when compared to lower intensity cardio. As long as HIIT sessions are kept to a short duration muscle loss not be a problem. In fact, muscle growth and muscle retention are increased due to the effects HIIT has on anabolic hormones. Just one 10-15 minute session of HIIT can increase testosterone and growth hormone levels for hours after the workout has ended.
Once again, it's about hormones. At night your insulin sensitivity decreases, meaning your body must release more insulin than usual to put any carbohydrates you eat at night to use in the body. And by now you know that higher insulin levels can decrease fat-burning and enhance fat storage. In addition, the body naturally produces a fat-liberating hormone called growth hormone within the initial 90 minutes of sleep.
I’m going to give you a super simple way to set your calorie intake. While people try to impress you with fancy equations, the truth is that the difference between the most complicated equations and the simplest (like the one I’m about to show you) is only 5%; and seeing your calories will be adjusted anyway, the easier it is to set your numbers, the less paralysis by analysis and the sooner you can start getting results. Cool? Cool.
Have you ever decided to skip a meal to cut back on your daily calorie count? Despite saving a few calories in the moment, this strategy almost always backfires. When you skip breakfast, or any meal, you'll begin to experience excessive hunger that can lead to craving unhealthy foods—and lots of them. You may also eat faster than you normally do after skipping a meal, causing you to miss the warning signs that you're full and resulting in overeating.
You will find that you lose up to 8 lbs quickly, which is your glycogen (and water) going down. Then you will plateau for a few days. I recommend you weigh-in only once per week, which will stop the emotional ups and downs. The mirror is your scale the rest of the time. The weight will come off in chunks after that. Nothing for a couple days, then sometimes 3-5 lbs in one day. It just keeps happening. But the mirror never lies.
Certain carbohydrates have a tendency to be poorly absorbed in your intestines and then rapidly fermented, leading to gas and bloating. Common culprits include refined carbohydrates and simple sugars—like those found in processed foods with added sugars. Excess sodium can also cause bloating due to increased water retention. Opt for freshly prepared foods and reduce processed, packaged foods to cut back on belly bloaters. In the morning, swap your sugar-laden bowl of cereal for this Green Smoothie, made with fresh fruits and vegetables to get your day started the right way.
Muscle tissue is a biologically active tissue, this means that it needs and uses calories just to continue being. Some studies have shown that 1 pound of muscle can burn up to 50 calories per day by simply existing. This means that if you gain 10 lbs of muscle you can eat 500 more calories per day and still lose fat. This is just one of many reasons why it is so important to preserve muscle tissue while cutting fat.
But in order to get to your goal as quickly as possible, you've got to forget about crash dieting. That's because making strategic tweaks to your diet and exercise plan, rather than skimping on calories and exercise bingeing, is the fastest way to torch fat and keep it off, says Torey Armul, R.D. spokesperson for the Academy of Nutrition and Dietetics.  
In addition to fat, you need to eat nourishing foods so you’re not hungry. When certain nutrient levels like iron, zinc, or B12 drop, your brain signals you to eat everything under the sun until you get it. (Really, look up pica. People with iron deficiency have turned to chewing on toilet paper to get it. Your brain doesn’t know that TP doesn’t have iron. It just tells you to keep eating until you run into iron.[3])
Our increasingly slothful lifestyles are partly to blame for skyrocketing obesity rates, so it’s no surprise that being more active is a simple fix for belly fat. In 2003, a first-of-its-kind study from Duke University showed that sedentary adults accumulated abdominal fat surprisingly quickly — and that sedentary women stacked on fat more visceral fat than sedentary men, even though they added less fat overall.
However, due to the intense exercise, the total calorie consumption is higher. We burn more calories due to the hard muscle work – even AFTER the run. The body needs more energy for recovery, thereby burning even more calories. That’s how you benefit from post-workout fat burning and the afterburn effect (EPOC, excess post-exercise oxygen consumption).
After clearing the tear ducts I am finally sitting down to share my successes. They come in many forms weight loss, inches lost, pain lost, and shedding emotional sadness carried for many years. I have given birth to 2 amazing kids and always stayed fit during pregnancies and post pregnancies, but my body seemed to work against me. I was spinning my wheels with workouts eating clean and getting no results which equaled a defeating dull pain and being embarrassed of who I was in my own skin. After 6 weeks of the FASTerWayToFatLoss I can honestly say I have been transformed. My mental and emotional transformation are the highiest on my list as these will continue to push me on this journey. It is a journey to be the best version of myself and provide a modeling platform for my children. One of my biggest joys is hearing my almost 2 year old asks me gym or run? When I put on my sneakers. In addition the 9lbs I have lost and most importantly 13.25 inches shed are not a bad prize. Thank you for this program that allows me to see results, live a healthy lifestyle, and even have some treats when I deserve them. I can't wait for the next chapter!
This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.
Belly fat is, in fact, the colloquial term for abdominal fat. According to medical experts, belly fat can be potentially dangerous. Excess of it can lead to a number of health problems including heart diseases, high blood pressure, type 2 diabetes, a decrease in the level of HDL or good cholesterol, and can even lead to strokes or sleep apnea. You need to combat this problem before it gets too late.

Repeat after us: It’s time to start eating clean. She recommends a combination of veggies, fruit, whole grains, nuts, seeds, beans, low-fat dairy and lean protein like poultry, eggs and fish for a dose of omega-3 fatty acids. And drop the added sugar while you’re at it. “Studies show that when you have a diet rich in whole grains — and calorie-controlled — that you can reduce the belly fat,” she says. But remember to watch your portions, too. “A lot of people eat very healthy and don’t eat junk, but their portions are too large.”
Before you even get started on a fat loss plan the first thing you want to do is to set goals for yourself. This goal could be to lose 30 lbs. or it could be to see your abs. Whether your goal is to lose a certain number of pounds or to just achieve a certain look you will need to set a reasonable time frame to achieve this. If you do not set a time frame there will be no sense of urgency when trying to make progress.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.

Carb crazy? Consider this: Refined carbohydrates, such as bread, potatoes and rice, create a surge in insulin that in turn drives down your resting metabolic rate, explains Aronne. "It's important to keep carbohydrates in your diet, but really focus on fruits, vegetables and whole grains, which have less of an effect on insulin levels," he explains. And when buying whole-grain breads and cereals, make sure the first ingredient listed is whole wheat, whole oat or cracked wheat.


With the body not able to use carbohydrates for energy it will begin producing ketones. Ketones are a by-product of fat oxidation and can be used as an energy source instead of carbs. With less carbs coming in insulin levels will be lower which leads to a greater rate of fat burning. As we now know, lower insulin levels are not always a good thing though.
But back it up just a tad.....I started following FWTFL after a post I read on Seersucker + Saddles. I followed for a while, like months and months. It's easy to make excuses not to do something when you're afraid to step out of your comfort zone. Well, April rolled around and I turned 38. I realized ANOTHER year had passed by and I still wasn't in the shape I wanted to be in, so it was time to think about my priorities. You see, my plan was to be "fit for 40" but at the rate I was going 40 would be here and everything would be the same. I knew we had a couple vacations planned for the early summer so as soon as those were out of the way, I pulled the trigger for the July 10th bootcamp. Since the beginning I was super psyched to learn and take in as much as I could. It didn't take long to start noticing changes in my mood and my energy, and even in the physical changes my body started having! The best part was the confidence that came with all that and the determination to keep at it. Its almost (no, very) addicting to get in good health with results to show for it! Once you get a taste of it you want to have more-more of those body changes and certainly more of that "I can actually really do this" feeling! I never thought I'd have the willpower to do all that Ive done these past 6 weeks.
^ Mann, T; Tomiyama, AJ; Westling, E; Lew, AM; Samuels, B; Chatman, J (April 2007). "Medicare's search for effective obesity treatments: diets are not the answer". The American Psychologist. 62 (3): 220–33. CiteSeerX 10.1.1.666.7484. doi:10.1037/0003-066x.62.3.220. PMID 17469900. In sum, there is little support for the notion that diets ["severely restricting one’s calorie intake"] lead to lasting weight loss or health benefits.
The Grey Box of Clarification: While my earlier comment about ‘sucking it up’ was slightly facetious, there is a lot of truth to it. Hunger is an inevitable part of dieting and the more you can become comfortable with it, the more successful you’re going to be with your fat loss. Also, read this. And then sign up to my email list because it’s the best thing since Deadpool. 
Whether or not you’re specifically aiming to cut carbs, most of us consume unhealthy amounts of sugar and refined carbohydrates such as white bread, pizza dough, pasta, pastries, white flour, white rice, and sweetened breakfast cereals. Replacing refined carbs with their whole-grain counterparts and eliminating candy and desserts is only part of the solution, though. Sugar is hidden in foods as diverse as canned soups and vegetables, pasta sauce, margarine, and many reduced fat foods. Since your body gets all it needs from sugar naturally occurring in food, all this added sugar amounts to nothing but a lot of empty calories and unhealthy spikes in your blood glucose.
Based on your results, a specialist will determine if you burn fat well or not. According to Dr. Arad, "If you're able to burn fat well, do a type of exercise that maximizes fat-burning, like a moderate-intensity run." If your results show that you don't burn fat well, "You may benefit from doing high-intensity exercise, like high-intensity interval training," Dr. Arad said.

Do this: Limit your total carbs on two consecutive days every two weeks or so to less than 100g per day. This will require you to know how many grams of carbohydrates are in the foods you eat and have the discipline to be very strict on your intake. Your diligence will be rewarded with a noticeable difference in body fat. After two days, you can return to a more normal, though not excessive, carb intake.

Another way to fill up before a meal is by eating salad. Lettuce has plenty of water content to take up space in the stomach. That leaves less room for fattier foods that might come later in the meal. Make your salad interesting by adding a variety of fruits and vegetables or grated cheese. Be careful about dressing, which can add a lot of 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.

Have you been skipping the gym lately? No judgment: So you overdid it on gingerbread lattes at Starbucks or grabbed too many fast-food meals after marathon shopping trips? No biggie—as long as you stay active in other ways. "A lot of people skip workouts completely when the holidays get busy and promise they’ll exercise in January,” says Mike Donavanik, a personal trainer in Los Angeles. “But it’s that much harder to motivate when you’ve skipped the gym for two-plus weeks.” While you don’t have to maintain your exact same exercise routine, keeping your body in motion will help you balance out the indulgences and start the year strong. To help you do that on the quick, we’ve rounded up a dozen research-backed ways to get more out of your workouts and improve your metabolism to boot.

Saturated fats in food will pack on more visceral fat than polyunsaturated ones, according to a 2014 Swedish study. When subjects ate 750 more calories daily for seven weeks, either in the form of palm oil (saturated) or sunflower oil (polyunsaturated), the former gained more visceral fat while the latter gained more muscle mass and less body fat. The study authors believe different fat types can impact both the way your body forms fat and stores it. What’s more, including healthy fats in your meals can make them more satiating and keeps hunger at bay.

You will feel hungry sometimes, but you can eat more fat if you do. The first three days, you may need L-glutamine. If your body is really toxic, you may feel headaches or like you got the flu. It passes in a couple days. If you need painkillers, go for aspirin, NEVER Tylenol. Tylenol will hurt your liver and make it hard to detox because it depletes glutathione.
But in order to get to your goal as quickly as possible, you've got to forget about crash dieting. That's because making strategic tweaks to your diet and exercise plan, rather than skimping on calories and exercise bingeing, is the fastest way to torch fat and keep it off, says Torey Armul, R.D. spokesperson for the Academy of Nutrition and Dietetics.  
The easiest way to cut calories? Eliminate excess dietary fat—meaning no butter, oils, or salad dressings (low-fat or fat-free dressings are OK); remove the skin from chicken; substitute egg whites for most of your whole eggs; avoid whole-milk dairy products; and ditch marbled red meats such as rib-eye for lean cuts such as flank. Keep some healthy fats in your diet, such as salmon, mixed nuts, peanut butter, and avocados.
With potatoes, leave the skin on (with baked or mashed potatoes) or if you peel them, make snacks of them. For example, drizzle olive oil, rosemary, salt, and garlic on the peels and bake at 400 F (205 C) for fifteen minutes for baked Parmesan garlic peels. Keeping the skin on potatoes when cooking them helps keep more vitamins/minerals in the flesh (just don't eat any parts of skin that are green).
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
Weight gain has been associated with excessive consumption of fats, (added) sugars, refined carbohydrates in general, and alcohol consumption.[citation needed] Depression, stress or boredom may also contribute to weight increase,[5] and in these cases, individuals are advised to seek medical help. A 2010 study found that dieters who got a full night's sleep lost more than twice as much fat as sleep-deprived dieters.[6][7]
Unintentional weight loss may result from loss of body fats, loss of body fluids, muscle atrophy, or even a combination of these.[26][27] It is generally regarded as a medical problem when at least 10% of a person's body weight has been lost in six months[26][28] or 5% in the last month.[29] Another criterion used for assessing weight that is too low is the body mass index (BMI).[30] However, even lesser amounts of weight loss can be a cause for serious concern in a frail elderly person.[31]
The best way to lose weight on the Bulletproof Diet is with Bulletproof Intermittent Fasting.  But if waiting for results just isn’t your thing, you can use this Bulletproof Rapid Fat Loss Protocol – but only if you are currently significantly overweight or obese, and you have healthy, functioning kidneys and liver.  However, you need to understand that your body stores toxins in fat that your liver couldn’t excrete, so when you lose weight very rapidly, those toxins are released and can make you very sick.  This Bulletproof Rapid Fat Loss Protocol helps you avoid any side effects from this toxin release, so it’s important to follow the plan carefully.
Intermittent fasting has blown up in the past year, but scientists are just starting to figure out how it can help you lose weight. In one study from the University of Illinois at Chicago, researchers compared obese people in a traditional weight loss group and fasting group. For the experiment, the calorie-restricted group simply reduced the amount of calories they ate by 25 percent each day. The fasting group, however, alternated days: they ate 25 percent of the calories they needed one day between 12 and 2 p.m., and then had feast days the next, where they ate 125 percent of their required calories.

Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
Whey protein is best known for its ability to increase muscle growth and recovery which becomes vitally important on any fat loss plan. Many of the benefits of whey are due to its fast digestion rate and high concentration of the amino acid leucine. It is important to remember that anything that is used to build muscle will also maintain muscle while dieting.
Wheatgrass has a high concentration of iron, magnesium, calcium, amino acids, vitamins C, A and E, B12, B6 and chlorophyll. These vitamins and minerals provide many therapeutic benefits. Consuming wheatgrass can rid the digestive system of harmful bacteria and cleanse the body of toxins. It also cleanses the colon and can help in the treatment of joint pain, ulcerative colitis, skin infections and can even prevent diabetes. No wonder it is regarded as a superfood!
It is possible to do more in less time — at least when it comes to your workouts. By incorporating interval training — that means bursts of high-intensity moves — you’ll give your metabolism a huge boost, says Glenn Gaesser, Ph.D., director of the Kinesiology Program at the University of Virginia and author of The Spark. If you usually jog at a consistent pace, try adding a 30-second to one-minute sprint every five minutes, or, if you’re on a treadmill, change up the incline for one-minute intervals.
Nuts are an excellent way to curb hunger between meals. They're high in protein, fiber, and heart-healthy fats. Studies suggest nuts can promote weight loss and improve cholesterol levels when eaten in moderation. They're also rich in calories, so limit your portions. If you have to get them out of their shell, you'll slow down and not eat as much.
Following two successful spinal surgeries in the last twelve months I have struggled with not only residual back pain but pain throughout my body. I was not sleeping through the night partially due to pain. Pain dictated nearly every choice I made every day. Although I was successfully managing my weight according to 'the charts', I had no energy, no vitality, no strength, and no vigor. I needed help. I am so thankful to have stumbled onto FASTerWayToFatLoss because everything has changed in 7 determined and disciplined weeks. This program has educated me on nutritional choices. I now use the right foods to fuel my body at the right times. Within five days of changing what I eat I was running sprints. I am now lifting weights, running, sleeping through the night. I am no longer a slave to pain as most of it is GONE. What remains I am successfully managing.
I just want to point out that it’s not necessary for people with a high level of body fat to go low carb, and as long as there is a calorie deficit in place, you will lose fat. However, from experience, people with high levels of body fat (20%+) tend to fare much better restricting carbohydrates initially. Their energy levels tend to stabilise, they feel less lethargic, cravings subside, and due to the water loss from going low carb, it acts as a motivator as they see results from the get go.

We don’t always eat simply to satisfy hunger. All too often, we turn to food when we’re stressed or anxious, which can wreck any diet and pack on the pounds. Do you eat when you’re worried, bored, or lonely? Do you snack in front of the TV at the end of a stressful day? Recognizing your emotional eating triggers can make all the difference in your weight-loss efforts. If you eat when you’re:
Keep a calculator handy. To calculate your waist-to-hip ratio accurately, measure the narrowest point of your waist and the broadest part of your hip. Divide the values you obtained from the measurement and you have your ratio. The waist-to-hip ratio is a more accurate parameter to measure BMI. Those with a waist-to-hip ratio of 0.8 are susceptible to cardiovascular disease and stroke.

1. High Intensity Interval Training (HIIT): This type of exercise is your key to melting belly fat fast.  HIIT is highly effective for all over weight loss, particularly removing stubborn belly fat. If you are not eating right, you have reached menopause or you are not losing weight you should do these exercises. Don’t let the name scare you as it is you who determines the intensity.  It is your perceived exertion that counts.
Another thing that messes with circadian rhythms? The blue light of digital devices. “We have seen increasing scientific evidence that the more you use devices, the higher your risk of obesity,” says Gillespie. The reason is twofold: One, the more time you spend in front of a screen, the less time you’re running around and playing. But also, experts believe, the blue light these devices emit can disrupt your internal clock. One study found that using a blue light-emitting device before bed delayed the release of melatonin, a hormone responsible for sleep, and the effect carried over to the following night as well.
