In general, no. 143 pounds is not fat for most people. But it depends on how tall you are, and also how active you are and the amount of muscle you've got. That's why it's best to ask a doctor if you're overweight or not.
Yes. You should consider medical help.
well the question is... Do You Feel/Look Fat ??
Well I am 14 and 9 stone, so maybe 12 stone or more?
The average weight for a 14 year old girl is about 8.5 stone - 9 stone :)
no
No
Yes.
The waist line of a fit 14 year old is around 27 to 30 now a heavy/fat 14 year old is more likely 30 to 34.
i wouldn't say it's good but i think a healthy 9 stone would be good for a 14 year old, maybe go on weightwatchers and hopefully you will will be a healthy teenager.
No.
1000inches
Nope...
depends how tall he is...if he's short then no that's not light. For an average height 14 year old I would say 8 stone is a little thin but nothing to worry about
