You're welcome, we're our own worst enemy!!
Yup, you can do:
5:5 (5 days PP and 5 days PV) personally I'm not mad about this one as I don't think I could hack 5 days of only Protein!! This was the original method promoted by Dr Dukan but a lot of people found it hard so he introduced...
1:1 (1 day PP and 1 day PV) this one you know so no need to explain. Finally you have:
2:5 (2 days PP and 5 days PV) this is more recommended for older people or people who don't have too much to lose. S
My preference is 1:1 as I find that the easiest to follow. Although, I actually do PV days on the both weekend days (Sat and Sun) and I lost every week (as you can see, with the exception of when I was on hols)
Good luck!
