Congrats on taking the next step to reaching a healthier you by getting active with SparkPeople - it's a great community, wonderful resources and fantastic support. You're off to a great start already, just by posting here, introducing yourself and sharing your story!
As for your question, just manually replace the restricted foods from the meal plans with something else you can eat that's approximately equivalent. In other words, if you were allergic to fish, you could substitute chicken. No fair replacing broccoli with chocolate cake, tho, haha! There are options for restricting some things such as gluten, seafood, tofu, eggs, etc. so you might be able to cover some of your food allergies that way. Click on the Change Tracker Options and go to Change Diet Settings to choose the exclusions.
Please check out the SparkTeams - I think you will find a lot of others 'just like you' including many with the same challenges, circumstances and goals. You can choose SparkTeams by age group, lifestyle or interests, geographic location or several other ways.
I'd like to invite you to join the Virtual Walk/Run/Cycle Thru the US @ exercise.lbl.gov SparkTeam - it's a really fun way to track your walking while you travel 'virtually' across America from Virginia to Oregon. Go to the SparkTeam page at www.sparkpeople.com/myspark/groups_i ndividual.asp?gid=19805 for more information.
Some of the other teams I like and think you might like include the Official 10-minute Daily Exercise Streak Challenge, Starting Over Weekly Mini-Challenge Team, 10k Steps A Day and Motivation & Positive Attitude Plan - but there are so many to choose from, you can have a great time looking for the ones that seem to fit you best! In fact, I suggest joining more than one group, post your intro there and write blogs as often as you can - you will find tons of friends and support that way, I promise!!
In my experience, SparkPeople is like a in some ways - it's lots of fun and easy to make friends because we're all in this together. I like the way a HEALTHY LIFESTYLE is emphasized instead of a 'quick fix wonder diet' so it's good for people wanting to lose weight, maintain a previous loss, get healthier, improve fitness and many other goals including gaining weight or saving money - it's about waaaaaay more than 'just' losing weight so you have definitely come to the right place!
If you ever need any help using features of the site, there are tutorial videos under the HELP section that can show you how to use the features of the site. You can also find them on the START page and several other places on the site.
Be sure to read and 'study' The Spark book because it outlines the overall program and is compatible with most types of eating plans. It's available in printed version, as an audiobook or as an ebook for Kindle - you can download the free Kindle reader for your computer or read it on a smartphone so you don't have to actually own a Kindle device to take advantage of this offer - I have it on my Blackberry and can read bits of it whenever I'm waiting in a line or feel like I need a 'reminder' of what I'm trying to do so check it out!!!
If you haven't already discovered the SparkDiet linked at the bottom of the START page, check it out - the program is simple but extremely effective. There is a TON of information on this site - so much it might even seem overwhelming but fortunately we don't have to 'digest' everything at once! The FastBreak program is a good way to start.
Another nice thing about SparkPeople is that we have permission to be human - we don't have to change everything at once or be in a hurry to reach our goals. Take a few baby steps and then a few more and before you know it, you'll have completed a long journey - I hope you enjoy this community as much as I have - it teaches us how to make positive lifetime changes because that's the only thing that will work over time!
