I'm doing 810 plan. On my first week (which was actually W8 packs but same thing really) I lost 9lbs, 2 week 3lbs, last week 2lbs (but I couldn't stay away from the cheese), this week its looking to only be about another 2lbs loss, but we'll see on Monday.
I have to say I am finding it soooooooo much easier than being on packs alone but don't know if I'm happy enough that I may only lose 2lbs a week, especially since I've not cheated this week. May just be a wee stall though and it will pick up, so I'll keep going.
Good luck, I've definitely found it makes a huge difference having the meal at night, you can keep going through the day much easier.
