Throw everything you've got at me!

It seems a little bit like you're overcomplicating things wanting to make a book- an inspiration book with exercise challenges is a great idea! A huge collection of information and meal plans is another matter. So my advice would be to keep things as simple as possible.

Also, know that if 50lb before mid-February may be setting you up for a fall- while 2lb a week is doable now, once you get closer to your goal weight loss slows down. What will happen if you dont reach that goal? You may end up feeling disappointed and give up. Having goals is great, but many people find putting time constraints on them can be really damaging to motivation (but at the end of the day its down to you).

Advice wise, I'd suggest first you read through some of these threads

Exercise challenges are a great idea! Fitnessblender is a great website with all sorts of workouts ranging in difficulty, type etc. I like to combine a few of their videos to make one longer workout (so a warmup 10min, cardio 20 min, exercise ball 10 min, and so on).

If you're making a scrapbook style thing have you thought about using Pinterest? It's a bit like a virtual scrapbook where you can keep all the helpful links and things you find. I love using it to keep all my recipes in one place

I second the "Most helpful posts - Getting Started" threads. Good stuff.

My advice would be to experiment with what works for you. Don't be afraid to try something, but also don't hesitate to ditch something if it doesn't work for you. E.g. I really enjoy cooking, and what helps me stay on track is preparing foods I truly love (and my family does, too) that I not-so-humbly believe are better than anything you could get in any restaurant that also fit my calorie & nutrition target. To someone who hates cooking, my approach (e.g. "meal plans") would be a nightmare. How good advice from anyone might be depends on your own life, preferences and style. If you can make the changes fit your life, you are a lot more likely to stick with them for life.

Best of luck!

Pinterest! Do a search for whole30 and 21 day fix meal plans. Even if you are not on the whole30 or 21 day fix program, the recipe ideas that come up are all clean, low fat/low cal and healthy. I rarely eat out anymore since being turned on to the wonderful world of healthy Pinterest meal ideas.

Don't give up learning about and trying everything until you find what works for you. And by 'works' I don't just mean you lose some weight. I mean you are happy doing it and not going crazy with the misery of hunger and frustration.

With 50 pounds to lose there is absolutely no way you'll lose it by February. I lost my first 50 pounds in 6 months BUT I still had 30 pounds to lose after that... once you're down to your last 20 pounds it's completely unreasonable to expect to lose more than 1 pound a week.

Keeping a notebook or scrapbook of your journey can be very inspiring. I print out favorite motivational quotes, my progress pics, weigh in numbers & measurements, comments from others, workouts I complete, etc. It's so much fun to look back at how far I've come, especially on the harder days. I recommend it for everyone. You can keep it electronically or on paper, but I like a paper book because it is easier to browse through. It's a 5x8 plain paper journal.

Food scale, move more, be honest, eat enough.
