I am very slim everywhere but my belly. (145 lbs.) i love my body besides that its not a lot of fat, but what can i do to get rid of just belly fat?

Targeted exercise: Diet, exercise and weight loss - with targeted exercise toward your abdomen. It will help strengthen the abdominal muscles. It sounds like you're developing male pattern weight gain, which is usually due to obesity and Insulin resistance, often pcos.

Agree: Some people like yourself are also predisposed to being 'skinny' and your excess calories will only accumulate at your waist, but as the doc mentioned you likely have elevated testosterone levels (acne, pimples) and thus prone to central weight gain. Liposuction or calorie restriction and exercise to decrease stool transit time.
