The FastDay Forum

One of Swedens biggest newspaper has a series of articles where they follow four person during their diet with 5.2.

They measure a lot of values in their bodies as the diet progresses, among those the one that interest me the most, IGF-1.


The last article is from after they have been on the diet for 2-3 months. I was really surprised to see that for two of them, their IGF-1 levels had risen a bit since the start. For one it had sunk (person 4 they did not mention regarding to IGF-1).

How come it had risen? I thought the main thing about 5-2 was that the IGF-1 levels should sink so the body would repair itself.

Can anyone explain these results?

Can't read the whole article as it's paywalled. I'd guess protein intake was not low enough. The research shows that lowering protein as well as calories is needed to reduce IGF1 in primates whereas in rats calorie restriction alone was sufficient.

Can you see in the article what the participants were eating on feed days and fast days?

It seems like one of them were cheating on her diet the last month and the other were eating meat yes. Thanks for the feedback!
