Getting rid of your belly bulge is important for more than just vanity's sake. Excess abdominal fat—particularly visceral fat, the kind that surrounds your organs and puffs your stomach into a "beer gut"—is a predictor of heart disease, type 2 diabetes, insulin resistance, and some cancers. If diet and exercise haven't done much to reduce your pooch, then your hormones, your age, and other genetic factors may be the reason why. Read on for 11 possible reasons why your belly fat won't budge.

The short circuits in Zero Belly Diet offer a variety exercises that blast your core without relying on traditional sit-ups—easy enough to squeeze in before dinner in the comfort of your living room. Within six weeks of incorporating the mini circuits, test panelist Krista Powell lost 25 pounds—and she was finally able to dress in a way that reflected her true sense of style: “I’d avoided wearing high heels because the extra weight made my knees hurt so bad. I can actually wear my heels with confidence and without pain!”

Eat foods with a low glycemic index. These are foods that take longer for your body to digest and convert into energy, so you will feel fuller throughout the day with a smaller number of calories. Moreover, you avoid the "sugar rush" that comes as a result of eating foods with a high glycemic index, getting a nice boost of sustained energy throughout the day instead. This will keep you uplifted whether you're doing work or exercising.
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
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.
In addition to making sure you don't wander in circles in the forest, the Instinct is a wellness tracker, keeping an eye on your steps, calories burned, stress levels (based on heart rate variability), and sleep quality. The Instinct has a 14 day battery life (or 16 hours with constant GPS monitoring), so you don't have to set it up on your nightstand every evening. Wear it to bed and it will track your REM sleep cycles and determine how restless you are during the night. There are even virtual fitness challenges that you enroll in from the Garmin Connect app to help keep you motivated.

3. Twist: One foot placed slightly in front of the other with body facing the corner. This should resemble the movement of wringing a towel while taking knees further “inward” and opening body in the opposite direction. Start with knees bent and straighten with the twist by lifting the hip and leading it to the opposite corner.10 reps each side, then 10 again (total of 20, alternating after 10)

Face it, if you want to lose weight over the long haul, your best bet is to make sustainable, long-term lifestyle changes like the nine simple ones this woman made to shed 45 pounds and keep them off. But sometimes life comes at you fast and you need a fast solution. One smart lifestyle change is to eat plenty of veggies—especially for someone looking to lose weight. Vegetables are nutrient-packed and provide plenty of filling fiber with hardly any calories. Plus, non-starchy veggies have a high water content, so they hydrate you while filling you up—the perfect combination for weight loss.

Have you been consistent with workouts but haven’t gotten the results you were hoping for? Your low-key resolution is to change up your workout. Commit to the same number of workouts per week, but make these workouts completely different. If you’ve been going to yoga three times a week, go to a cycling class instead. Or if you’re walking on the treadmill every day, move over to the recumbent bike instead. By sparking a change in your routine, your muscles will be forced to work differently and hopefully you’ll begin to see the results you’ve been hoping for!
