Strategies for hunger and brain fog on 16:8 fasting in a sedentary job

[Thomas68]

I've been practicing a 16:8 intermittent fasting schedule for about three months to manage my energy levels and weight, and while I've seen some positive results, I'm hitting a plateau and struggling with intense hunger and brain fog during the late afternoon, which is affecting my work focus. I'm curious if I need to adjust my eating window, change the composition of my meals, or if this is a sign my body is adapting and I should push through. For those with long-term experience, what strategies did you use to overcome similar plateaus and manage hunger cues, and how did you tailor your approach to fit a demanding, sedentary job? I'm also wondering about the long-term sustainability of this pattern versus cycling different fasting protocols.
