Hi @lovemyparrot, thanks for the link.

I do like the idea of small - or simple - changes. Although a different approach to that suggested by the article, I think the reason 5:2 appealed was that it was a small change (in one sense) - 2 days a week you eat a lot less, but 5 days a week you do not have to make any change. Very simple.
I do wonder if, for some people, when they (initially) combine 5:2 with other changes, that it may end up being too much and they give up after a while. I feel that it may be a safer path for many to stick to the basic 5:2 until comfortable, then start making other (small) changes such as reducing snacking or changing to healthier snacking, changing refined grains to whole grains, replacing starchy carbs with other veggies, etc. And not increasing the actual fasting period until you feel able. Or the number of fasting days.
Of course, some people do fine by making big changes all at once - as the article also says - but this approach will not work for everyone. Based on our own experience, we may be able to work out which approach is more likely to work for us.
I am a strong supporter of the first point - eat lots of fruit and veg! And also of the second point of not having artificial sweeteners. But I am not a fan of dark chocolate, although I understand how others can be - I love the creaminess of (good) milk chocolate too much!!
The idea of replacing bread/wraps with lettuce leaves was suggested to me a while ago by forum members (carieoates or rawkaren I think) and I have used that successfully. However, I also realised that there are times when to have the bread/wrap may be appropriate - eg if I am doing a lot of exercise (eg a long hike) then the carbs seem to satisfy my fuel needs and keep me in a better frame of mind than, say, protein bars.
Don't think I have answered your question about other tips tho!!
