Hi and welcome
Everyone else has pretty much said everything although I did want to add in one little tidbit, they pick the number 20 for induction because eating less then 20 isnt going to have any add benefit. 20 seems to be the good number for ketosis, but you aren't doing yourself any favors by eating less than that. Your body DOES NEED carbs, just the good kind, not the processed junk.
I am not on by-the-book induction. I eat as many carbs per day as I feel comfortable with, as long as they are good carbs. Like today I know I was over 20, but almost all of my carbs came from veggies. I know I'm doing well because I am hungry about 6 times a day (every 3 hours or so) but I only need a little feel full and happy again. I'll give you an example: Here is what I ate today:
Breakfast 6:30 - atkins advantage shake (they are good for my really busy mornings! )
9:30 - colby jack cheese stick, small handful of grapes, 2 strips turkey bacon
11:30 - dark green salad w/ tomatoes, cucumbers, some shredded cheddar cheese, chicken and a lil bacon - 1tsp ranch
(normally I would eat again before this time, but I took a long nap today, and I wouldnt eat so late in the night either. Between lunch and dinner I usually have some LC yogurt with 1/2 a cup of low glycemic fruit like berries, or maybe some nuts like sunflower seeds on top of cottage cheese)
7pm- cube steak, green beans, dark green salad with lil dressing and tomatoes
11pm - beef and broccoli, with LOTS of steamed broccoli.
Drinks: a lil over a gallon of water a day, at least 74oz minimum
I get my sweet kick naturally, from fruit. Once you start induction and get rid of all the crap in your body, your cravings will lessen and the food that you think you want know, won't even taste as good anymore. You'll start wanting different things too. We went to mickey d's for icecream last night, and I thought I would treat myself. So I got like the kid's cone, plain, and about 10 minutes after I ate it (it tasted SUPER SWEET) I got soooooooo sick from all the sugar. You will start craving natural things, like sweet from fruit, or a nutty taste, or more veggies. At least that is what my experience has been.
Anyways, sorry to ramble
Hope some of it helped
Welcome aboard, get the book read and have fun!

Are you forgetting you are supposed to eat veggies? Those should take up carb counts. And yes, you should be trying to get close to the 20. True, sometimes it's not possible. But I'm wondering if you're eating enough. If you don't, your body won't lose weight (it'll go into starvation mode). Plus, don't forget your water (I've discovered how important that is). And yes, dancing IS exercise! So go out and shake it 
for now
