I need to choose a diet... pls help

I need to lose about 40 to 50 lbs. I want to do it the healthiest way possible, so I'm not in a huge rush.. it's taken 10 years to gain the weight!

I was skinny until I started gaining weight around 22 years old and now I'm 33. My main problem is that I think I don't eat often enough then I overeat when I do eat. I also go through periods where I exercise a lot then I stop for months. I've had problems getting to the gym so I've asked someone to send me some exercise tapes to use at home.

I have a very inconsistent schedule and I don't like to cook.

I wonder if the only way to lose weight is if someone prepared meals for me. BTW I live in Jamaica so the prepackaged plans aren't really an option.. at least I've never seen them here.

What do you guys think?
