<human>: Can you give me the gist of the text in a nutshell?

As the title suggest, I'm a 15 year old dude from the capital city of Wales, Cardiff. I'm still in high school and I'm looking to lose weight for the summer.

Although I don't have precise measurements, I know that I am 5 foot 11 and weigh around 14 stone. I've always had trouble with my weight; when I was younger I had routine check ups at hospital because my parents though I had an eating problem. I was obese as a child.

Luckily for me though, puberty has been very kind and I've managed to outgrow that. I'm a lot taller now, so the stomach isn't nearly as noticeable. I'm still not satisfied though.

I'm not athletic at all. I have really bad asthma which hinders me from doing a lot of things (such as running, although I've never really been much of an endurance person. May I also note that the awful weather we get here doesn't really help my asthma) as well as an awfully messed up right shoulder (3 dislocations, recently had an operation to get it fixed). This makes certain things rather uncomfortable. I would go to the gym, but I'm just too young to be able to join any of them.

I'm a particularly fussy eater, but if it means that I'll lose the fat, I'll try anything. :) 

All of that aside, I love walking and swimming and try to get out as much as I can (which isn't too often because the weather, as previously stated, is awful. Constantly.). 

So r/loseit, where do I start my journey? What are some ways that I can begin to lose some weight? 

Thank you very much in advance!
