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.
Green tea is rich in antioxidants that boost the body's process of cleansing and detoxification. The most potent antioxidant is catechins and one of these is epigallocatechin gallate (EGCG), a substance that boosts metabolism  . Another beneficial compound present in green tea is caffeine, a natural stimulant that has been found to burn fat  .
These little black morsels of nutrition are packed with fiber, protein and, most important of all, omega-3 fatty acids. Pair chia seeds with green tea in a smoothie to turbocharge the tea’s fat-burning powers. According to a study review in the International Journal of Molecular Science, omega-3 polyunsaturated fatty acids may enhance not only the bioavailability of EGCG, but also its effectiveness.
Fat accumulated in the lower body (the pear shape) is subcutaneous, while fat in the abdominal area (the apple shape) is largely visceral. Where fat ends up is influenced by several factors, including heredity and hormones. As the evidence against abdominal fat mounts, researchers and clinicians are trying to measure it, correlate it with health risks, and monitor changes that occur with age and overall weight gain or loss.
The stress hormone cortisol can really screw with your belly. The problem with cortisol is two-fold: First, the chemical makeup of cortisol causes the body to store visceral fat. Visceral fat is stored between your main organs and in the midsection and is the most dangerous type of fat. Experts state that visceral fat increases the risk of diabetes and heart disease.
