I'm 5'5 9 st 13lbs .... I think i'm pretty fat/chubby so would like to lose weight... At which weight do I look best? Or none ! How much weight should I lose - best methods?
You look fine to me. The only thing that'l make you look better at this point (imo) is working out at a gym, to make your muscles more defined. That'l get rid of the 'chubby' look that you're referring to.
You can keep losing weight but without working out you'l just start going skeleton mode lol.
You arent fat (as im sure you know) and you are a BMI of 23 which is in the normal range. You could lose more weight if you wish to get leaner. If you want a better looking body then you should lift weights.
As I've said before I don't believe you need to loose any weight, most guys would find you attractive, However, if you're self-conscious about how you look then you could try Intermittent Fasting which is what I'm doing atm to lose weight, it works quite fast though so be careful
