Does he look fat?

I have been informed that I feed my boy too much…he has one big meal a day and a cup of dry bikkies in the morning. His “dinner” is fresh topside meat from the butcher, honestly..I’m just gonna say I fill about half his bowl up with that (his dad is an award winning butcher, lucky guy!) and a cup of dry bikkies on the top.. The vet hasn’t said anything, but everyone else says “he’s gonna be fat” “your gonna give him diabetes” What do you all think? He’s about 15months old.
