Get bronchitis and get over it, then get a relapse thats worse then first case. It does wonders for weight.
Seriously though, below is the best advice:

you could stick to a routine, cardio + muscle simultaneously will lead to quicker results. Eating healthy like salads is good, however you need to ensure your body gets the right amount of suppliments (because you're starving yourself if you don't eat adequately). Try using vitamin and protein supplements as well as eating the right amount of food (suggested intake for each food group). Avoid splurging, and over eating. Snack on fruits and veggies and do not use oil or anything fried.
I'd also add to the above, eat more times. If possible try to have 4 or 5 smaller meals a day rather then 3 larger ones, or the famous huge dinner at night with snacks throughout the day.
It's all in watching what you eat, moderation and being active.
You don't even need to join a gym. Do push-ups, sit-ups, pull-ups (if you have something to grab onto) and lunges or squats with just your body weight a couple times a week, that will help out.
