I need motivation, advice, something of the sort.

I think I know where you're coming from. Personally, I work in a grocery store, and that contains pretty much what a convenience store has and more. I used to forgo bringing home lunch because I'd just pick up something from the store or one of the nearby lunch shops. Not only is this a terrible habit, it's EXPENSIVE! I'll tell you what I do now and maybe you can get some ideas from it. Remember, small changes lead to big ones over time, so don't worry if it seems slow, you'll get there in the end. Just make a small change today, and a year from now, it could be huge.

I picked up a couple of "gourmet" healthy cook books, because let's face it, it doesn't matter how healthy it is, if it tastes like doodoo, I won't eat it. Stuff like the Insanity or P90x cookbooks could be good places to start. Then I went through all of them, finding the meals that looked tasty to me. Then I picked out two meals per meal block (ie breakfast, post workout, lunch, afternoon snack, dinner), for about 9-10 meals per week. I went through the ingredients, making a rough draft of a shopping list, then consolidated and substituted similar foods so that I wouldn't have to buy all sorts of ingredients that spoil before I use it. For example, if a recipe called for a whole wheat english muffin, I might sub that with a ww slice of bread because I already had some. I pick one night from the week (usually Sunday) where I prep whatever meals I can for the week, and put them in prepacked containers. Groceries usually run me about $60-75/week. Not bad when you remember that it's for ~35 meals.

I know it sounds like a lot of work, but it's worth it in the end. It's saves time through the week. Also, when I bring a prepacked lunch(es) to work, even though there may be tastier junk food, I'll eat my healthy food because it's right in front of me. Circumvents the temptation.

And for not wanting to exercise, we've all been there. Sometimes you just have to find a time of day where you feel like it can be done. I used to wait until dusk to run because that's when I used to feel energized, but sometimes I'd come home from work tired and just would not work out. Now I've committed to waking up a little earlier and jamming in my workout then. When it's done, I feel great, and when I get home I can just relax knowing my workout is done. I also get bored with my workouts, so I tend to just change it up on a whim. I mainly just aim to do something physical for at least 30 min a day. If I get bored of running, I lift. Lifting gets boring, I'll do hikes. Tired of hiking, I'll do some DVD workouts. Just keep trying new things, and you'll meet new people who will help you.

Oh, and I'll also share with you my wacky exercise thing. Sometimes I just don't want to leave the house. I want to watch TV and stay inside. I want to stay barefoot. So I do all of that, but I exercise. I'd put on my favorite show (usually on netflix) and play something like a drinking game. Every time a character says his catchphrase, I'd do five squats. If they fight, five pushups. If they sing, run in place for the entire song. You get the idea. Weird, but I enjoy it.

It's a lot of trial and error till you find what works for YOU. Don't give up; we're all here because we're in the middle of our journey, not because we're finished.
