How harmful is ruining the fast a couple times a week?

I have found I do pretty good on the 16/8 fast window and I am losing weight, my window of eating ends @3pm latest but a couple of times a week I will eat dinner out and that's like 7-8pm, is that setting me back a lot? I guess I could just wait and see but I am newish ( a few weeks on and off) in this so idk what's your experience with this? Just relaxing couple of days a week or am I just making it harder on my body to adjust to a schedule? via /r/intermittentfasting https://ift.tt/aN89i4k https://ift.tt/NnoT20u
