If you are not losing belly fat even after trying different diets and exercising regularly, then probably your body has low magnesium. Magnesium is necessary for more than 300 chemical reactions including regulating blood sugar levels and it is also important in weight loss and losing belly fat. A study published in the Journal of Nutrition found that when you consume higher levels of magnesium it is associated with lower levels is fasting glucose and insulin. These are the markers related to fat and weight gain. Another study found that magnesium supplement may have some beneficial effects on reducing fluid retention. It especially beneficial for women during the menstrual cycle.
The can eat more magnesium rich foods like leafy green vegetables, beans and nuts. You can also take a supplement with recommendation from your doctor.
If you're not losing belly fat even though you exercise regularly, then it is likely that you are doing the wrong workout. Many people follow the steady state cardio workouts which include long jogs, to lose belly fat and weight. This approach of running at a consistent pace for 45 minutes may help you to lose some pounds initially but soon your metabolism will adjust accordingly and you will stop burning calories.
If you want a better and more effective way to lose belly fat, then you should go for weight training. Lifting weights will force you to spend more energy or burn more calories. When you lift weights, some micro-tears happen in your muscle and healing of them means more energy and it can last up to 2 days after you training session. The most effective workout for fat loss is high-intensity interval training or HIIT. It is effective because it raises your heart rate while working on your muscles. It will not only help you to lose inches from your waist and hips within a few weeks but it will also help you to drastically decrease abdominal fat.
If you are not sleeping enough, then also it may become very difficult for you to lose belly fat. Sleep is a complex process and it has many influences in your body and mind. Lack of sleep can have some serious consequences when you're trying to lose fat. If you're a woman and you are sleeping five or fewer hours every night, you are likely to experience major weight gain in comparison to women who got more sleep. A scientific study found that when women got four hours of sleep instead of eight, they consume more than 300 extra calories every day and that came mostly from fatty foods. When you sleep less, your body will produce the ghrelin hormones in high quantities and this hormone is responsible for stimulating appetite.
You need 7 to 9 hours of sleep a night and you need quality sleep. Remove anything that can distract you, keep your room cool, avoid caffeine after lunch and always try to maintain the same sleeping schedule.
