I posted on a dog forum I am on about the 5:2 as there is a health section and these are some of the responses
Fasting never achieves anything except weight gain and ill health and throws your metabolism all over the place which regulates how you burn energy and store fat amongst other things.
Metabolism problems, hormone irregularities, mood problems, and plain old fatigue. You can’t tell me that anyone feels good on 500, 600 calories a day. How do you put in a full day living life on that few calories? You certainly aren’t living an active life that way, and activity is key to gaining health.
I just think it’s a very distorted and unhealthy way to look at food. Well, any restrictive diet would be, but one where you fast like that even more so.
This article by a dietician explains it much better than me:
