Is it too much food or just poor quality food?
A few decades ago meals were made at home with fresh ingredients and three equal portions of veggies, protein, and a starch.
I was fortunate you visit Hawaii before the fast food invasion... now the Hawaii locals are all "it is great! Soooo convenient!" (never mind rampant obesity and diabetes in native peoples)
And let me be first to say isn't it great that we men are immune and not getting fat!!!
