Belly fat is excess abdominal fat surrounding the organs in your stomach. There are three types of fat: triglycerides (the fat that circulates in your blood), subcutaneous fat (the layer directly below the skin’s surface) and visceral fat (dangerous belly fat). Visceral fat is located beneath the muscles in your stomach and poses many dangers to your health when there is too much of it.
Most of the bacteria that dwell in your gut are pretty useful. They produce hormones, regulate your immune system, digest food, extract nutrients, control your mood, manage your appetite, and much more besides. That obese people tend to have higher numbers of Firmicutes bacteria is no coincidence – according to research published in the online journal Nature, these bacteria increase the number of calories your body absorbs from food.
The traditional hot-dog topping can do serious wonders for your waistline. "Fermented foods like sauerkraut, pickled veggies, and kimchi are some of the best sources of probiotics — a form of good bacteria that support healthy digestion and decrease bloat," says Frank Lipman, M.D., founder of Eleven Eleven Wellness Center in New York City. "That's important, since diets low in probiotics can cause bad bacteria to overtake the good ones, leading to health problems ranging from autoimmune diseases to weight gain."
To banish stubborn belly fat, you have to ramp up your workouts. In a study published in the journal Medicine and Science in Sports and Exercise, people who completed a high-intensity workout regimen lost more belly fat than those who followed a low-intensity plan. (In fact, the low-intensity exercises experienced no significant changes at all.) "You need to exercise at full intensity because the end goal is to burn more calories, and high intensity exercise does just that," says Natalie Jill, a San Diego, Calif.-based certified personal trainer. High intensity workouts mean you're going all out for as long as you can. If this sounds intimidating, think of it this way: you'll burn more calories in less time.
A 2012 study in the Journal of Functional Foods found that people who drank one and a half cups of green tea enriched with a total of 609 milligrams of catechins (a group of antioxidants that have been shown to help burn fat cells) every day for 12 weeks lost almost 16 times as much visceral fat as those who consumed green tea without the added antioxidants. To achieve similar results with store-bought green tea, you’ll need to brew two to four cups daily (many varieties can contain 160 to 470 milligrams of catechins per cup).
It's easy to down a handful of nuts, but pump your brakes: "A common diet tip you hear all the time is to snack on nuts when you're hungry," says Adam Rosante, personal trainer and author of The 30-Second Body. "They're filling and packed with protein and fiber, and because they're so tiny it's easy to gobble down handful after handful. But you should enjoy them in moderation because the majority of their macronutrient profile is fat, and eating them mindlessly is an easy way to go overboard on your calories." To get your fix and avoid the belly fat, Rosante recommends going for a thumb-sized portion twice a day.
The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
You've heard it before, but it needs to be said again, as at least 70 percent of Americans aren't listening: "Staying up late may make you happy in the moment, but all that sleep you're skipping catches up to you in the form of extra fat around your middle," says Ilyse Schapiro, R.D., a certified nutritionist and co-author of Should I Scoop Out My Bagel? Yes, "me time" is important for your sanity, but "when you're lacking sleep, your body overproduces the appetite-stimulating hormone ghrelin, and under-produces leptin, which tells you when you're full." Getting proper shut-eye — the National Sleep Foundation says seven to nine hours is best, though it varies per person — truly stops unnecessary snacking when you wake up the next day.
Focus on compound moves like deadlifts, squats, kettlebell swings, lunges, chest presses, shoulder presses — exercises that work your entire body rather than isolating muscles. Simply put, you cannot 'spot-reduce' fat, meaning that endless crunches will do little for getting rid of your belly. For best results split your sessions over different days.
The secret to a slimmer stomach in no time? A whole lot of fiber in your diet. Although many people are loath to add carbs to their diet when they’re trying to lose weight, adding the right, fiber-rich ones can have inches off your belly in a hurry. In fact, researchers at Wake Forest Baptist Medical Center found that every 10-gram daily increase in soluble fiber was associated with a 3.7 percent decrease in dangerous visceral fat over five years. Those who were active got even leaner, shaving off twice that much fat in the same amount of time. To start ditching that extra belly fat today, add the 30 Best Foods For Fiber to your menu!
In that age range, girls are just hitting puberty. It is a period of faster growth than any other time in their lives since infancy. Limiting calories is therefore not a good idea for girls in that age group, since their bodies need extra energy in order to grow, unless they are having health problems due to weight. Making healthy dietary choices and getting plenty of exercise are good ideas. Just keep in mind - the belly fat that many girls accumulate early in puberty tends to move elsewhere in their later teens.
Once you’ve established a regular cardio routine, add two or three weight training sessions on nonconsecutive days to your weekly workouts; everyone naturally gains some fat as they age, but building muscle tone can significantly slow the production of belly fat. In a study conducted at the University of Minnesota, overweight women who did twice-weekly strength training routines that included eight to 10 exercises of major muscle groups, from biceps curls to leg presses, gained 67 percent less visceral fat over two years than women who didn’t do strength training regularly.
Stress wreaks havoc on every part of your body, and can lead to breakouts, joint pain, headaches, and yes, even excess belly fat. That’s because when you’re stressed, your body pumps out extra cortisol, that not-so-great hormone you keep hearing about. Studies show that cortisol not only spikes your appetite, but may also redistribute body fat to your belly area, according to a review published in the journal Obesity.
Instead, build up to at least 150 minutes per week of moderate-intensity cardio, such as swimming, jogging or hiking. A duration of 250 minutes per week will lead to more significant weight loss, explains the American College of Sports Medicine. This means 250 minutes a week for several weeks or months, though; you're unlikely to see dramatic results after one week.
Losing belly fat shouldn’t mean strict dieting or deprivation. “People often think that you have to eat certain foods or avoid certain foods [to lose weight] and in reality, it comes down to eating more of a balanced diet that is portion- and calorie-controlled,” says Zeratsky. “This allows your body to have enough energy to do what it wants to do while managing weight.”
