I think it happens to a lot of us. The way I have started to cope with business and it sabotaging my diet is to pre prepare my food.
So, the evening before I will chop up fruit, veg, prepare snacks and lunches and put them in containers in the fridge.
I also tend to do lots of things that would ordinarily need chopping up for cooking in the evening and store those in containers too, our fridge is full of boxes! haha.
I know it's a bit of a pain to have to do stuff in your evening when you would rather relax etc, but it makes such a difference on the day you are busy to just be able to grab and go.
Best of luck, you can do it
