Use an adult energy needs calculator to estimate your calorie intake needs; then subtract the 500 to 1,000 calories for weight loss. For example, a 28-year-old woman who is 5 foot, 9-inches tall weighs 175 pounds and is lightly active -- less than an hour a day -- burns about 2,400 calories daily. She'll burn about 2 pounds of fat in a week if she eats 1,400 calories daily, or 1 pound a week if she eats 1,900 calories a day.
Another reason is the genetic factor. In case obesity runs in the genes, it will take place and it cannot be helped. Excessive calorific intake transforms into fat and calories, so the more junk food you eat, the fatter you get. Stress is another indicator of belly fat accumulation. As it is human nature to eat more during stressful times, this tends to add up the calorific intake. Another factor influencing belly fat is a lack of sleep which results in the gas formation and puffing up of the belly.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time without exercise. 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 cherry-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.
