Going very low calorie (some plans are as low as 500 a day!) is sometimes considered more effective for significant weight loss, rather than just reducing to just-under-maintenance. I think partly because you don't have to stick to it for as long to get results! To be honest keeping weight *off* long-term without constant vigilance is the nightmare, and I don't think anyone has an answer for that one.

I think I might be able to cope with keeping them for one-a-day if I don't manage to stick to the total-replacement scheme for 2 weeks anyway. I'm definitely not going back to calorie counting everything I eat though - I guess that's the other advantage of a total diet replacement plan - no having to plan/count/measure everything you eat.

I did consider Jane Plan at one point, because it's a we-provide-your-food plan with more normal calorie counts, but they still needed you to add your own veg to meals as well, which kind of ruined the point of you-do-all-the-thinking-for-me that I was looking for :)
