Many guys and girls are skinny until they start to go through puberty. The changes that come with puberty include weight gain and, in guys, broader shoulders and increased muscle mass.
It's considered a normal transformation for girls to gain weight, particularly in the stomach area. What is this? Don't fret too much if you notice your daughter is gaining belly fat before puberty. It's all part of the growth plan.
Replace refined carbs with whole lentils & whole cereals: Instead of eliminating all carbs, however, you can focus on cutting out refined carbs and processed sugars and eating whole grains and plenty of fiber.
For example, a 7-year-old boy who is 3 feet 11 inches (119 cm) tall would have to weigh at least 56.9 pounds (25.8 kg) ( BMI = 17.9) to be considered overweight, and a 13-year-old girl who is 5 feet, 3 inches (160 cm) tall would be considered obese if she weighed 161 pounds (73 kg) ( BMI = 28.5).
Lean body mass in girls diminishes from approximately 80 percent to 75 percent by the end of puberty, while the amount of body fat increases. In comparison, the percentage of lean muscle mass in boys increases from about 80 percent to 90 percent by the time they reach adulthood.
However, the growth spurt tends to cause increased hunger, which may accelerate weight gain in teens who eat in excess and do not get enough physical activity. Children in their early teens (13 to 14-year-olds) are likely to gain weight naturally as a result of hormonal changes during puberty.
Even though a 13 year old who is 70 kg is considered to be overweight as they suggest you should be weighing more like 50 to 60 plus kg, you are a growing teenager (providing that you are still growing, I'm only saying this because when I was your age I stopped growing unfortunately for me).
But if they do need to slim down, experts say teens shouldn't drop more than 2 pounds a week. Talk with your child to get their buy-in. They have to be on board and involved with any plan to lose weight.
It is usually easier to lose weight as a teenager than as an adult due in part to metabolic differences. It is beneficial to achieve and maintain a healthy weight as a teen and carry it forward into adulthood.
Noticeable weight gain may occur prior to a growth spurt as excess fat helps promote growth. As a child goes through puberty, their stores of body fat may change.
Most girls grow fastest about six months before they start their first period (menarche). You'll probably gain weight in puberty -- most girls do. You may notice more body fat along the upper arms, thighs, and upper back. Your hips will grow rounder and wider; your waist will become narrower.
What is the average weight for a 13-year-old? According to the Centers for Disease Control and Prevention (CDC), most 13-year-old girls weigh around 76–148 pounds (lb) and most 13-year-old boys weigh between 75 and 145 lb, but this can vary widely. The average weight of a 13-year-old will depend on a number of factors.
Teens should limit their fat intake to 25 to 35 percent of their total calories every day and they should choose unsaturated fats over saturated fats whenever possible.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
The truth is that under the right training and nutrition programme a person can lose an average of five per cent body fat in as little as ten days.
