Hi:
This gives some research results on the necessity for quite a bit of fat in the diet: https://www.youtube.com/watch?v=QetsIU-3k7Y
It is interesting that carbs (including veggies and fruit) are unnecessary for human health or survival: http://irosacea.org/articles.html/_/rosacea-articles/triggers/rosacea-and-sugar/carbohydrate-not-essential-for-human-survival-r21

Well, I guess I don’t know what your goal is.
If it is to lose weight, then 5:2 is where you should start – without consecutive diet days. You get the same weight loss results as consecutive days without the ‘pain’ – especially if you are just starting out.
There is no research indicating two consecutive diet days are better than only one at a time if you are interested in anything other than weight loss. Current research is that to get real ‘other’ benefits from fasting you need to go quite a few consecutive days without any food. Dr. Longo (from the BBC program that popularized 5:2) seems to think five consecutive days are a minimum, about once a month, for several months. He is developing low calorie, high nutrition foods to help a person actually do this. We will see if he succeeds.
Your insulin levels will fall when you eat high fat/protein meals on any day, and especially on diet days. This is good if you are trying to cure diabetes, but helpful in general. However, you can do that without consecutive diet days – two days a week is two days a week, wherever they come.
Here are some tips for those just starting 5:2: http://thefastdiet.co.uk/forums/topic/warnings-to-newbies/
Good Luck!

I understand, but there was nothing ‘magical’ in the two consecutive days. It was just how they configured the study (it sounds like you have it, but here it is for those that are reading this and do not: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3017674/).
Here is Mattson in a 2014 speech explaining his research in a very short format: http://www.youtube.com/watch?v=4UkZAwKoCP8 In it he advises just to ‘play around’ with IF, advocating no particular pattern of diet days.
One thing you have to remember is that Mattson’s animal research has been with rats/mice and if they don’t eat for 2 days, its like humans not eating for a week or more. The Harvie study was simply to see if they could lose weight, and the conclusion was that if they ate less on two consecutive days and ate a specific diet on the others, they could. There are lots and lots of people on this site alone who can confirm 5:2 works just fine for weight loss even if they diet on two non consecutive days.
You can do what works for you, but for most people, non consecutive is the way to go, especially at the start. You will not experience better/faster weight loss doing two in a row – there is no clinical study that I know of that even suggests that as a possibility.
Good Luck!
