In that age range, girls are just hitting puberty. It is a period of faster growth than any other time in their lives since infancy. Limiting calories is therefore not a good idea for girls in that age group, since their bodies need extra energy in order to grow, unless they are having health problems due to weight. Making healthy dietary choices and getting plenty of exercise are good ideas. Just keep in mind - the belly fat that many girls accumulate early in puberty tends to move elsewhere in their later teens.
The number one reason it’s so hard to lose belly fat: hormones. With menopause comes a drop in estrogen; this decrease alters where the body stores fat, making women more prone to gaining visceral belly fat. Other hormonal imbalances during this time can leave the body feeling hungry, even after eating. Sleep disturbances, common in perimenopause and menopause, are associated with decreased levels of leptin (an appetite suppressant) and increased levels of ghrelin (an appetite stimulant).
Subcutaneous fat is that pinchable, soft-belly layer of body fat in your stomach area. The subcutaneous tissue layer lies directly under the skin and is vital to protecting the muscles and bones whenever we fall or our bodies hit something. The subcutaneous layer is also a passageway for blood vessels and nerves to travel from the skin’s dermis level to the muscles.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a berry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
Go ahead. Pop up a bowl. Sans the butter and salt, popcorn is a real gut whittler. Why? Because popcorn is a whole grain—and a study revealed that people who ate lots of whole grains had smaller middles compared with folks who ate mostly refined grains. So while you're waiting for yours to pop, clear all the white rice, pasta, and bread out of your cupboards. (Related: Give your popcorn some low-guilt flavor with these tips.)
Visceral fat—a type of fat that lies deep inside your abdomen and surrounds your internal organs—is linked to a whole slew of terrifying health problems like heart disease and type 2 diabetes, according to the Mayo Clinic. Even scarier: According to the National Heart, Lung, and Blood Institute (NHLBI), your risk of those health issues increases even more if your waist size is greater than 35 inches for women and 40 inches for men.
