IRS Tax Tip 2011-48, March 9, 2011. When filing your federal income tax return, taxpayers can choose to either take the standard deduction or to itemize their deductions. The IRS has put together the following six facts to help you choose the method that gives you the lowest tax.
Calculate the correct amount of protein. According to Drugs.com, 12- to 14-year-olds should consume approximately 1 gram of protein per kilogram of body weight each day. Girls aged 15 to 18 need slightly less protein, or 0.9 grams per kilogram of body weight. Find out how many kg your teenager weighs by dividing her weight in pounds by 2.2. For example, if your 13-year-old weighs 100 pounds, she weighs 45.5 kilograms, and should consume about 45 grams of protein each day.
For example, if the body requires 2,000 calories each day to maintain its weight, a teenage girl will lose 1 pound of body fat each week by consuming 1,500 calories each day. Dieting or not, your teenage girl needs to consume an optimal balance of the three macronutrients: carbohydrates, fat and protein. For a teenage girl, about 45 to 65 percent of total caloric intake should come from carbohydrates, 25 to 35 percent from fat and 10 to 30 percent from protein. If she follows a 1,500-calorie diet, she should consume about 750 calories from carbohydrates, 450 from fat and 300 from protein.
