I agree also.
So to get slimmer arms, loose weight and tone them up by
exercising.
If u want to do weights, read up first or get professional advice.
U don't want tough arms unless you are a guy. Even so, i believe
guys want nice muscular arms, not lumpy ones. 
Losing weight is to lose the fats. Do exercises or weights is to
build the muscles. Do weights without losing the fats = big arms
