A reasonable daily diet for an adult is 2,000 food calories. That's 8.36 megajoules per day, or about 100 joules per second -- in other words, 100 watts. Most of that ends up as heat, so you warm a room as much as a bright light bulb. Cut your consumption by 600 calories per day and you'll lose a pound of fat every week. Most diet experts consider that a reasonable goal. Don't drop below 1,000 calories per day, or you might get lethargic. But at 1,400 calories per day, you can easily maintain an active life.

Postmenopausal women who tried yoga for 16 weeks reported significant reductions in visceral fat in one 2012 study. If you're just not that into downward dog, any sort of relaxation exercise (even simple deep breathing) can help. The key is to lower levels of the stress hormone cortisol, which is linked to belly fat. (Try these two-minute stress solutions to calm down fast.)
One of the very first cardio exercises to reduce belly fat is walking. Surprised? Do you think it’s too simple to be effective? Well, then you should know that walking is a great and effective way to burn away that ugly belly fat. In fact, it is an excellent fat burner for your entire body. If you follow a healthy diet along with walking at a steady pace for 30-45 minutes for at least four to five days every week, you will witness a gradual decrease in your weight.
3. Be realistic about which habits need to go. "When I was heavy, I'd eat French fries every single day, plus carbs at almost every meal—like a sandwich for lunch or bread with pasta for dinner. A diet so heavy in fried food and carbs just isn't conducive to weight loss. To lose the weight, I went from three large meals a day to six small meals, mostly made of fresh vegetable salads with lean meats and nuts. And no more bread!"
Losing weight is hard—it takes a lot of sweat and starvation, right? Well, actually, it doesn't have to. While hitting the gym and eating healthy is the surefire way to be your healthiest, fittest self, sometimes you need to start small or build up some extra credit to get over that plateau. That's where these 10 little tricks (backed by science!) will come in handy to help you drop pounds without even trying. 
Make sure to program your cardio exercise in with your weight training the right way, though — a 2017 study found that performing cardio and weight training workouts on alternate days was far more effective for burning belly fat than stacking the workouts on top of each other in the same session. Put the two together, and watch that unhealthy midsection shrink.
There is some scientific legitimacy to today’s lower-carb diets: Large amounts of simple carbohydrates from white flour and added sugar can wreak havoc on your blood sugar and lead to weight gain. While avoiding sugar, white rice, and white flour, however, you should eat plenty of whole-grain breads and brown rice. One Harvard study of 74,000 women found that those who ate more than two daily servings of whole grains were 49 percent less likely to be overweight than those who ate the white stuff. Eating whole grains is not only one of many great ways to lose weight; it can also make you smarter.

Dieting and exercise go hand in hand. If you thought that only dieting will burn your belly fat, you are wrong. If you really want to lose weight, you need to include an hour of exercise in your daily routine for targeting and reducing belly fat. Here, we have compiled a list of 16 exercises that can help you reduce belly fat faster than you thought it would take:
8. Find friends with similar goals. Obesity can be “contagious,” meaning you could gain weight if you hang out with people who are obese, suggests a 2007 study published in The New England Journal of Medicine. That’s not to say you should give someone the cold shoulder because of their weight. But keep in mind that your peers have an influence on the choices you make, Bowden says. Surround yourself with friends who enjoy getting active (like the ones who think a 10-mile hike on the weekend is a good time).
At breakfast, go ahead and drink orange juice. But throughout the rest of the day, focus on water instead of juice or soda. The average American consumes an extra 245 calories a day from soft drinks. That’s nearly 90,000 calories a year—or 25 pounds! And research shows that despite the calories, sugary drinks don’t trigger a sense of fullness the way that food does.
Use a calorie-needs calculator like LIVESTRONG.COM’s MyPlate app to figure out your daily calorie needs, then subtract calories to create your energy deficit. With an app like MyPlate, you can factor in your weight-loss goal, and it will tell you the exact number of calories (as well has how much fat, protein and carbohydrates) you need to reach that goal.

"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
One of the top belly fat-building offenders is stress — and not just because that bad day at work can make you feel like demolishing a pint of Cherry Garcia. When your body senses you're overwhelmed, it automatically starts producing cortisol — a hormone has been proven to eff with your body chemistry and stimulate extra fat storage in your gut. Yeah, sucks. When you're feeling worked up, close your eyes and take long, deep breaths for about five minutes. You'll immediately start to feel more relaxed, which should calm those hormones down and nix that belly sabotage.
After dinner, wash all the dishes, wipe down the counters, turn out the light, and, if necessary, tape closed the cabinets and refrigerator. Late-evening eating significantly increases the overall number of calories you eat, a University of Texas study found. Learning how to stop late-night snacking can save 300 or more calories a day, or 31 pounds a year.
Here’s a shocker: When a group of U.K. researchers told 30 women to avoid chocolate, then packed them into a room filled with the stuff; the women were much more likely to sneak a bite than individuals who hadn’t been given the order. Blame the allure of the forbidden: The more you tell yourself you can’t eat something you love, the more you’re going to want it.
"Inadequate intake of calories, especially protein, causes the body to breakdown muscle tissue to meet the needs for amino acids," says Cederquist. "I have my patients focus on obtaining adequate lean protein and spreading it throughout the day." Her recommendation: focus on 100 grams per day, which breaks down into three to four ounces of protein at breakfast, lunch, and dinner, and a few ounces for snacks.
How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, 'The trick is not minding that it hurts.' I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.
1. Get clear on what motivates you. “Try to connect with the real reason you want to lose weight,” says Jonny Bowden, PhD, a Los Angeles-based board-certified nutritionist. “Beyond a slimmer waist, what do you really want? Is it more energy? Better sleep? More mental clarity? The ability to run a block without getting winded?” Once you've identified your goals, write them down. Seeing the bigger picture might help you make better day-to-day decisions, Bowden says.
1000 crunches a night may get you strong abdominal muscles, but with a full layer of fat on top, you will not get the results you really want. Instead of all those crunches, do exercises that engage multiple muscle groups and work your cardiovascular system. Try planking, where you hold yourself in a push-up position, resting your forearms on the ground. Try 3 or 4 sets of holding for 30 seconds each. Getting up and moving throughout the day by going for walks will also help.

While the Duke study found no added benefit to resistance training (aka weight or strength training) when it comes to belly fat, a 2014 study from a Harvard University team found otherwise. Twenty minutes of weights a day was linked to less of an increase in belly fat (particularly for older men). “Engaging in resistance training or, ideally, combining it with aerobic exercise could help older adults lessen abdominal fat while increasing or preserving muscle mass," said the paper’s lead author Rania Mekary.

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.

Listen up: Skipping meals will not make you lose weight faster. If a hectic day makes a sit-down meal impossible, stash an energy bar or a piece of fruit in your car or tote, keep snacks in your office desk drawer, and make a point of getting up to grab a nosh — anything that will keep you from going hungry! Going long periods of time without food does double-duty harm on our healthy eating efforts by both slowing down your metabolism, and priming you for another binge later in the day. (Think: You've skipped breakfast and lunch, so you're ready to takedown a whole turkey by dinner!) Make it your mission to eat three meals and two snacks every day, and don't wait longer than three to four hours without eating. Set a "snack alarm" on your phone if needed.
Some antidepressant medications can cause weight gain, especially the older tricyclic antidepressants (TCAs) such as Tryptizol, Saroten, and Clomipramine; as well as newer drugs such as Remeron (Mirtazapine). Lithium (for manic-depressive disorder) often causes weight gain. The most common antidepressants known as SSRI’s (for example Citalopram and Sertraline) usually don’t impact weight significantly.

When you exercise on the rowing machine, try this interval workout: Row for 60 seconds, note the distance on the machine, then rest 60 seconds. Repeat, only this time, row for 55 seconds and try to match or better your distance from the first time. Rest 55 seconds, then repeat, reducing the time to 50 seconds. Continue until you can’t beat your original distance.
1. Bicycle Crunches are a great ab exercise and work the abs from every angle. It’s a combination of the regular crunch, a side-to-side motion that hits the oblique muscles and a reverse crunch that targets the lower abs. You can change the difficulty level by increasing or decreasing the range of motion used and the speed of movement as well as the intensity of the crunch by holding and squeezing.
Belly fat is something that makes you look really bad and it is also very unhealthy. A sedentary lifestyle and wrong food choices are responsible for belly fat. However, not to worry, you can always do some core strengthening exercises to get the desired washboard abs. Here are some expert tips to show you the way to shed those extra pounds from your belly.
7. Trick out your weight-loss plan with technology. For weight loss motivation, look no further than your pocket. Many smartphones have built-in pedometers that will measure the number of steps you take each day, Ziltzer says. Aim to log 10,000 steps a day. You can also find free apps and websites that will help you track the foods you eat and calculate your daily calorie intake.

Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
8. Find friends with similar goals. Obesity can be “contagious,” meaning you could gain weight if you hang out with people who are obese, suggests a 2007 study published in The New England Journal of Medicine. That’s not to say you should give someone the cold shoulder because of their weight. But keep in mind that your peers have an influence on the choices you make, Bowden says. Surround yourself with friends who enjoy getting active (like the ones who think a 10-mile hike on the weekend is a good time).

For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
Still not convinced to make sleep a priority? A lack of sleep doesn't only affect how much and which food you eat, but also how it metabolizes that food. Insufficient sleep messes with your metabolism by making your body more insulin resistant—a condition that usually leads to diabetes and weight gain—according to a 2012 study published in the Annals of Internal Medicine. (And, get this, it even changes your fat cells.)
And as people get older they tend to become less active, which means you burn fewer calories all day long. Plus, you naturally lose muscle mass due to hormonal changes, which further drops your daily calorie-burn rate. Muscle tissue burns more calories than fat tissue, so a body with less lean tissue has a lower metabolism and is prone to weight gain.
How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, 'The trick is not minding that it hurts.' I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.
"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.

If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
“Trans fats don’t occur in nature, so our bodies weren’t designed to metabolize them,” says Schoffro Cook. “That means they can’t be properly digested, throwing off blood-sugar levels and contributing to obesity.” A six-year study found that a high-trans-fat diet that included foods like margarine led to a 33 percent increase in tummy fat. By contrast, she says, “coconut oil speeds fat-burning.”
Science backs these ideas up when it comes shedding belly fat: In one study published in The Journal of Nutrition, researchers had overweight men and women follow a high-protein diet (30 percent protein, 40 percent carbs, and 30 percent fat) or a high-carb diet (15 percent protein, 55 percent carbs, and 30 percent fat). After one year of weight loss and maintenance, they found that the high-protein group experienced a 21 percent greater weight loss and 27 percent greater body fat loss on average than the high-carb group.
You’ve heard of a self-fulfilling prophecy? If you keep focusing on things you can’t do, like resisting junk food or getting out the door for a daily walk, chances are you won’t do them. Instead (whether you believe it or not) repeat positive thoughts to yourself. “I can lose weight.” “I will get out for my walk today.” “I know I can resist the pastry cart after dinner.” Repeat these phrases and before too long, they will become true for you.
There are different types of HIIT but an easy one to begin with is to simply warm up for 3 minutes on an elliptical machine or by walking.  Then work out for 30 seconds so that at the end of the exercise you feel satisfied.  Reduce the speed to slow down to a moderate pace.  Do this 7 more times or for total 8 intervals. Start with one interval and as your body is ready to take more increase the intervals.  Studies show that HIIT to be the absolute premier cardio for weight loss and optimal health as compared to longer, traditional cardio.
Listen up: Skipping meals will not make you lose weight faster. If a hectic day makes a sit-down meal impossible, stash an energy bar or a piece of fruit in your car or tote, keep snacks in your office desk drawer, and make a point of getting up to grab a nosh — anything that will keep you from going hungry! Going long periods of time without food does double-duty harm on our healthy eating efforts by both slowing down your metabolism, and priming you for another binge later in the day.

Make it your mission to eat three meals and two snacks every day, and don't wait longer than three to four hours without eating. Set a "snack alarm" on your phone if needed.
We know that this type of fat—called visceral fat—churns out stress hormones like cortisol and inflammatory substances called cytokines that affect the body's production of insulin. The result: Besides obesity, you're also looking at increased risks of type 2 diabetes and heart disease. No thanks. Check out these nine tips to finally rid your body of that excess stomach.
We know, you've probably heard these a thousand times. But if you can make these small swaps day-to-day, you'll spare enough calories for the treat foods you really want or to go into a calorie deficit (a.k.a. the key to weight loss). (And this is just the tip of the iceberg. We have 50 more easy ways to cut calories.) Making these simple swaps is the way to health-ify your eating style and lose weight without actually dieting. 
“It can take 12 minutes or longer for the signal that you’ve started to eat to make its way to your brain,” says Mark S. Gold, M.D., of the McKnight Brain Institute at the University of Florida. Quick tips: Sip some water between every bite of food you eat, or at least eat more meals with friends or family members. You’ll be more likely to talk and therefore to eat more slowly.
10. Give yourself time to lose the baby weight. If you decide to start a family in your twenties, know that it’s normal for it to take six months to a year to get back to your pre-baby weight. Give yourself at least six weeks after giving birth to start a weight-loss plan, recommends the National Institutes of Health. If you’re breastfeeding, wait two months. And don’t be too hard on yourself. “Your body has just endured a massive transformation, and prior routines are turned upside down once kids enter the picture,” says Sopov.
You know that protein's essential for a slimmer you. But here's why protein really needs to play a prime roll on your plate: "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University. Insulin promotes fat storage—especially around your belly—and a diet high in protein may protect you against insulin resistance, says Aronne. In one study, obese women who followed a diet for eight weeks that was roughly 30 perecent protein, 40 percent carbs, and 30 percent fat lost significantly more fat—including visceral pudge—than women who stuck to a plan that was 16 percent protein, 55 percent carbs, and 26 percent fat.
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.
