I'm very sorry that the OP feels the need to walk away from all the members of the challenge and I'm glad to see that others have stepped in to keep this going. The changes that have been made work well .. and promote healthy habits.
Please understand that it's not my intention to "yell" at anyone and I absolutely do NOT want to close down a challenge. Challenges are important - as I said, they build community and they really do help people by giving them a unique support system. And the competition element doesn't hurt either.
My concern was that I got 3 PMs from 3 separate people on the same day asking me to come have a look at the challenge. When I saw the recommendation that people eat "no more" than 2 servings of veg, and when I saw some of the calorie levels that were posted, I felt that it was important to comment.
No one expects all our members to be nutritionists or fitness "experts" by any means, but I would say to all members as a general rule - if you think you might want to run a challenge, PLEASE do your research before doing so. Remember that when you choose the role as leader of a challenge, you are providing guidance and information for your participants - some of whom may be complete newbies to the world of losing weight, getting fit, and learning to eat right. You are, in effect, setting yourself up as someone with knowledge, a leader, and even to some degree an "expert". If you don't feel capable to accept that role, then finding someone with more experience to help you in leading the challenge is something you could consider as an option.
There is no blame being apportioned here - just a reminder to make sure you're being safe and healthy while you're having fun!
