It's not on mine yet either. I think the rollout just started. If your profile says you're female, it will eventually show up as a new tile you can add when you hit "edit" at the bottom of the dashboard.
It's very hard sometimes to keep your mind shut when someone is in crazy diet mode or keeps the story - it will always be hard, I need rules (as 50 grams of carbs max and 800 calories per day) as I am obese and you don't understand as you were never obese.
I feel like asking - how many rules like this you tried before, and how did this work last time? I feel like saying, sure it will be hard -you sound determent to keep it hard, this sounds like torture. I can't say this, I know when I was all fired anti sugar I would have not heard sane advise. You can only float your own canoe.
