Not all fat is bad. Healthy or “good” fats can actually help to control your weight, as well as manage your moods and fight fatigue. Unsaturated fats found in avocados, nuts, seeds, soy milk, tofu, and fatty fish can help fill you up, while adding a little tasty olive oil to a plate of vegetables, for example, can make it easier to eat healthy food and improve the overall quality of your diet.
The key to losing belly fat with exercise, though, is making sure your sweat session is intense. You’ll want to be working at 85% of your max heart rate at least, says Olson. “The higher your heart rate, the higher the release of epinephrine into the bloodstream and cells,” she explains. “A positive side effect of epinephrine is that it also activates greater release of abdominal fat into the bloodstream to be used for energy.”

So it’s no wonder that losing weight and getting in shape are among the most popular resolutions year over year, because so many people can’t keep them; 80% of New Year’s resolutions fail by February. So Moneyish spoke with several leaders in the field of obesity research and prevention who have reviewed the science surrounding weight gain and loss to explain what to eat and avoid; how much exercise you need and which workouts work best; as well as their tips for making these moves a part of your new, well-balanced life in the New Year.

Rather than a long and low-intensity cardio workout, try the HIIT method of cardio: intense, fast-paced intervals that leave you completely exhausted after only a 20- to 30-minute session. This form of cardio training increases the afterburn effect, allowing your body to continue burning calories long after your workout is over. You can rotate between 30 seconds of your favorite exercises, with rest in between, as long as they work different muscle groups—such as squats, push-ups and kettlebell swings.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
9. Relax. Believe it or not, you may be trying too hard to lose weight. If your workouts are very intense and your diet is too strict, you could over train and burn out. Your mind and body will just not respond in the same way when they’re tired. Muscles need rest to repair and grow, and sometimes your brain needs a break from constant calorie counting and worrying about the last few pounds. Instead of becoming frustrated and diving into a box of cookies, try to relax and reduce the intensity for a little while. You may be surprised to find the scale moving again when you give your mind and body a rest.
Bran muffins sound like a healthy breakfast option—with all that cholesterol-lowering oat bran, right? But the prepackaged ones found at the supermarket aren’t nearly as fresh or healthy as they claim, and they’re almost always oversized, packing in some 300 calories—about the same as a cream-filled doughnut! Many are also loaded with saturated fats butter and oil and contain upwards of 600 grams of sodium. Homemade is key when you’re trying to lose weight, so why not try making your own? While baking definitely does take more time than going to the store, you’ll reap the benefits of all your hard work spent in the kitchen.

Instant oatmeal may be a lot quicker to make than traditional oats, but what you gain in convenience you lose in nutritional value. Many of the oatmeal’s healthy properties are stripped away in processing, explains Stephanie Lincoln, an eating psychology specialist and the founder and CEO of Fire Team Whiskey Military Health and Fitness. Plus, sugar is added during manufacturing. These two factors turn instant oatmeal into a high glycemic index food, making you feel hungry even after you’ve just eaten. One study found that people who ate instant oatmeal for breakfast instead of eggs were found to eat 81 percent more food during the day. And one thing you don’t want when you’re trying to lose weight is the munchies. Next, don’t miss these 42 easy tricks for losing weight fast.
Frequent and sustained cardio training is one of the best ways to burn fat and boost metabolism. One of the best cardio exercises to perform is running, according to the American College of Sports Medicine, as it burns a high number of calories per hour and improves cardiovascular health. ACSM recommends training five days a week, with a minimum of 60 minutes per session.

Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.

The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
