With super-sized plates, takeaway meal deals and food advertising bombarding us from every angle, it's no wonder many of us are eating larger portion sizes than ever before.
According to the British Heart Foundation, most English meals are four times larger today than they were in the 1950s, and the average size of ready made, shop bought meals has more than doubled in the past 20 years.
British data also says a supermarket pizza has grown from 200g in 1993 to 460g today, while a chicken pie has expanded from 160g to 240g.
And judging by New Zealand health stats, which say 31 per cent of Kiwi adults are obese, and a further 35 per cent of us are overweight, we aren't much better when it comes to super-sized food portions.
So how much should we be eating?
