How to Get Rid of Belly Fat in a Week

You're fed up with your belly fat, and you want it gone -- now. Your abdomen didn't expand in one week, so you can't expect it to slim down in that short time either. Use a week to introduce measures to help you lose belly fat over time and reduce bloating. You might feel a little lighter after seven days, but true loss of fat will take several weeks or months.

How to Lose Belly Fat

Belly fat is a metabolically active type of fat that sits deep inside the abdominal cavity. It surrounds internal organs and releases compounds that make you vulnerable to metabolic disturbances, heart disease and inflammation.

Belly fat may be dangerous, but it's also responsive to traditional weight-loss strategies of diet and exercise. One pound of fat equals 3,500 calories; thus, to lose a pound, you must consume 3,500 calories fewer than you burn. In a week, you can't afford much more than a 3,500- or 7,000-calorie deficit without severely depriving yourself of nutrients and solid food. This deficit means you'll lose 1 or 2 pounds per week.

Some people can lose more than 2 pounds in a week with a dedicated fitness program and serious dietary restrictions.The time and effort required to lose weight that quickly is grueling and usually unsustainable, though. Even if you can lose a notable amount of weight in a week, a lot of it will be water weight -- not true belly fat. Weight you lose quickly is likely to be regained quickly too.

Exercise to Lose Belly Fat

Belly fat is usually the first weight lost when you start an exercise program, explains Rush University Medical Center. If you are new to exercise or coming back from a long hiatus, you can't expect to hit the gym for hours at a time to burn off fat that first week. This only increases your risk of injury and burn out.

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.

Strength training is another critical component in belly fat loss. You can't crunch your tummy away, but you can participate in a full-body strength-training program that addresses all the major muscle groups. Do this at least twice a week to build muscle, which helps boost your metabolism. The results of strength-training are gradual, however. One week of strength training won't induce the changes in your body necessary to improve your metabolism, but over the long haul you'll see improvements.

Dietary Changes to Reduce Visceral Fat

Belly fat also responds to a lower-calorie diet that's full of healthy, unprocessed foods. Go for lean protein, fresh produce and whole grains at meals. When you have just a week to lose as much as possible, ban all sweetened drinks -- including soda and juice -- bakery treats and ice cream. Also avoid refined grains, such as pizza and white bread, as well as alcohol. Keep your portion sizes to just 2 to 4 ounces for meats and other proteins and about 1/2 cup for grains. Over the long term, these dietary revisions help you drop belly fat.

Resist the urge to use a diet that promises quick results. Often they don't work, or they're so restrictive you can't handle them for more than a couple of days -- let alone a week. If you do stick to the plan, you may very well see a drop in pounds -- but it's not from a substantial amount of fat; it's mostly from water. A quick-fix diet teaches you nothing about sensible eating that will help you manage your belly fat and health forever. You'll likely gain all the weight back as soon as you resume your normal eating habits.

Reduce Bloating This Week

Although you can't lose substantial fat in a week, you can jump start the weight-loss process. Also make a few dietary and lifestyle changes to reduce bloating so your tummy feels flatter.

Avoid over stuffing yourself at meals; eat small meals throughout the day. Chewing gum and drinking with a straw can cause excess air to gather in the digestive tract. Carbonated beverages, spicy foods, large servings of beans or cruciferous vegetables, dried fruits and fruit juice often induce gas and bloating. If you're lactose intolerant, avoid dairy products to help reduce belly swelling; make sure you obtain important nutrients, such as calcium and vitamin D, from milk alternatives or other fortified foods.
