Yeah, hard to offer advice not knowing where you're coming from. I did my first (and only so far) IM last November. I'd signed up a year before, so I was specifically training for that for a year, but I'd been doing shorter distance races for 4 years before attempting that distance. Could I have done it sooner? Sure. But that was my journey.
I couldn't afford coaching or anything either, so I based my training plan off one in "Training Plans for Multisport Athletes." I didn't do everything I should have done to be ready for race day, but my goal was only to finish, and in under 15 hours if possible. And I did!
I had planned to lose the 30 pounds or so wanted to lose in the first 6 months of training, then crank it up when I began following the 6-month training plan, but the weight loss didn't happen. I found that I was so hungry when I was training so much that I ate all the calories I was burning. At a certain point I had to just accept that if I was going to finish the race, it was going to be at the weight I was at. Again, I did it, but if you're still looking to lose weight, or hoping that the training will help with that, just know that it might not work the way you're thinking.
Let us know what other specific questions you have, and good luck!
