What kind of shoes are you wearing? If your shoes are old or not designed for the type of exercise you're doing, they can really hurt your feet. If you haven't already, you might want to visit a good shoe store in your area and get a good pair of cross-training shoes, not sneakers or running shoes.
1. During ignite, you're supposed to avoid foods with added sugar; that includes honey, stevia, and agave. All of those are ingredients on the 'sneaky ingredients' list. I've seen the smoothie recipe which call for chocolate Fuel and cocoa powder; I'm not sure if there are any recipes that call for baking chocolate (although it seems unlikely since most brands also have dairy). During balance, it seems like this is loosened somewhat, to foods with no more than 10g of added sugar. Page 12 of the Ignite Quick Guide talks about this more: http://assets1.dailyburn.com/...
2. During balance, you have a certain number of 'cheats' per week (10 or 15, depending on how much you workout). You can do whatever you want with them. The idea is that you can reintroduce each of the evil 6 to see if you do have a sensitivity to one of them, and avoid it in the future. But if you want to eat dairy, no one will stop you. (The Quick Guide also talks more about Balance).
You can prepare quinoa in basically the same way you make oatmeal (on the stovetop; I've never tried microwaving it). You can dress it up the same way you would oatmeal. The texture is different, but I like it better than oatmeal, and it has more protein.
If your floors are that loud, you should get a rug to absorb some of the noise. You can also use a mat when you work out to reduce the noise level.
I have a Fitbit flex and while I like it, I wouldn't say it's amazing. The sleep tracking on the flex isn't as informative as you might think and it doesn't measure heart rate (I don't think the force did either, but they recalled that one). You can easily get a pedometer that tracks steps and calories for $15, maybe less.
You're not supposed to have more than 10g of added sugar or more than 20g of total sugar. You can have sugar in small amounts, and more natural sugar is preferable to more refined sugar. You can read more in depth if you go Nutrition, then Resources.
Peanuts are actually legumes, so they fall under the 'starchy carb, use sparingly' category.
Vitamin water has a lot of sugar, about 30g per bottle. That's way too much to count as not having added sugar. And Vitamin water zero has artificial sweeteners. You should try to find something with less than 10g of sugar to drink. Or even better, try tea, coffee, or water.
Agave nectar is another form of sugar. It might be even worse than honey or regular sugar because it has a high fructose content (think high-fructose corn syrup, which is also something to avoid) and may be related to insulin resistance (that can lead to diabetes).
There are some items that it's better to spend more for organic, and some that you can skip the organic versions for. The Environmental Working Group maintains the most well known list of the 'dirty dozen' (things you should buy organic) and 'clean fifteen' (things where you can skip the organic). You can see the list here: http://www.ewg.org/foodnews/s...
