I am 5.6 tall, and Weight 57 kg... is the overweight for a 14 year old?
Converting that to pounds (what I can understand : ) that makes you 5'6" and about 126 pounds. Sounds absolutely perfect to me!
How can I find out the ideal weight for my height and age?
Go see your doctor before you get concerned, they can clearly evaluate your true BMI.Firstly, you're working out regularly so you can toss this chart in the trash:Secondly, so many factors go into healthy body composition that any simple "rule of thumb" (or maybe a chart per se) is over generalized. I am just a touch over 5'10" and weigh 200 lbs. I don't look like a football player, nor a marathon runner, but I'm certainly not borderline obese as this chart would have me believe. I play sports and have worked out my entire life. My strength to weight ratio is ideal but you would never guess me at 200 lbs. (btw..I win a lot of stuffed animals at the County Fair when they guess my weight). Once upon a time I was concerned about my BMI and its possible effects on my health. My doctor told me that bone density, muscle concentration and cell mass differ with all of us. I guess it was his way of telling me that I was dense! (rim shot). He then told me to get out of his office and enjoy my stuffed animal collection. I'm sure your doctor will tell you much of the same.
