Am I overweight at 5ft 8 and 10 stone or 140 lbs and if so how can I lose weight?

I am assuming you are a guy, if you are a guy, don't worry, you SHOULD NOT, lose wieght because atm, your BMI is at perfect range, and anywhere between 125-160 is good. I am 151 5ft8 and My friends call me jacked and etc. Don't worry,

and if you are a girl, that is problem the best weight for you.
