You will feel more confident because the immediate reaction of others will already be more positive. An example: Before I was fit, I only had to look in the direction of a girl to see her facial expression change to one of disgust, or she would roll her eyes or sigh visibly, turn away, walk away, etc., just because she expected me to talk to her. Now that I am fit, I can make eye contact, smile, and they either remain neutral or smile back, I can approach them, and there is no negative tension or weird expressions, no immediate rejection. This experience alone has taught me to be more confident. Basically, it was many neutral or positive reactions that boosted my self-confidence. You can't expect girls to suddenly be attracted to you, but you may be attractive enough to them that they don't mind interacting with you.
