Boomerang has stopped eating the pellets

I had a good week but feel we've gone back a step or two.

I stopped all food apart from his toast in the morning to get him onto the pellets. Last week i introduced an evening meal of pasta, veg, sprouts or a bit of fruit and he's stopped eating the pellets for the last few days.

I think i should just give him some breakfast so he's forced to eat the pellets for the rest of the day. What do you all think?
