As far as I can tell, the only thing that dieticians are consistently against is sugar in large doses.
I'm failing to some degree on these, I admit.
There is no money in fasting, intermittent or otherwise.
There is, and that’s a good thing for both sides of the transaction.
No, I wouldn’t say this is modern consistent dietary advice. So many people that make it there business to talk about diet are hyping intermittent fasting now.

Not all sugar is the same. In fruit is in fructose form and "fiber bound". Refined sugar is the devil, but so are most refined products.
Fructose be absorbed by cells with little to non insulin. Also, in the company of fiber it gets absorbed slower into the blood (less sugar spike).
Finally there's the fat-sugar issue: in the company of fat (fatty blood) the muscle/liver cells become less insulin sensitive.
I regularly binge on fruit, but only when i have not eaten ANY fat yet for that day. I do this for 2+ years now and I find a lot of benefits.
Although for sure, you have to be careful drinking a lot of fruit juice etc.
