I am not apple shaped-I am hourglass-big boobs, big butt and thighs, smaller waist-but I don't think that it is HARDER to lose weight if you are a certain body type-you just have different problem areas. Apples usually have great legs, and hourglasses and pears usually have nicer waists and upper bodies, while our problem area is our buns and thighs. You just have to accentuate your good points and work extra hard on your problem areas.
gma2gone-you can still be an apple shape even if you have a larger behind, even though they are usually notorious for having "no butts."
You are an apple if you have most of your fat stored in your tummy, chest area (I don't mean the breasts, you can be an apple with small ones, I mean your whole chest and back area is usually heavier) and in your shoulders and upper arms. Apples usually do not have a defined waist.
