Ok, I checked your other posts, and I'm really concerned. Your only 16, honey, your parents are probably worried sick! 300 calories are unexceptible, for anyone, at any size...
I did the calculations for you ok.. But listen I'm a mom, and my oldest is just a year younger then you, and I swear I would want to be involved as a parent with something so important.
I'm going to give you this information, and then I want you to share it with your parents, and I would incorage you to have them do some research online for you and double check my math, and possibley have a doctor supervise. "Dieting" is a bit different for someone your age. You are still growing, dispite how tall you are, you are still developing.
Ok, this is what I did, and this is the info I want you to share with your parents.
I went to to figure out how much calories your body uses even when you sleep. It came out to 2,132.2...
Then I took that number, and did the Harris Benedict Formula.
It's that number your BMR x 1.55 if your moderatly active which came to 2,976 calories
BMR x 1.375 If you are lightly active (which it sounds like at the moment you are) it came to 2,640 calories
Now that's the amount of calories your body needs to stay at your weight. Which I figured to be 278lbs... (1 stone equals 14lbs, your 19 stones and 12lbs).. If I'm wrong with this then the calories I said aren't right....
Ok, once you know how many calories you need to stay at your weight, you can take about 20% deficet (check with your parents, this may not be ok for a 16 year old)...
If your moderatly active, you need to eat
2,536 calories a day, and you will loose weight at a healthy rate, and be full!
If your light with activety, you need to eat
2,112 calories a day, and you will loose weight at a healthy rate and be full!
Drink water!
I am not an expert, and you or your parents should double check the math I am very tierd, but I hope you read this before you go to school tommorow! You need to be eating so much more... You will loose, without hurting yourself!
