DOCTOR’S NOTE
A metabolic difference that brings down blood-sugar levels hours after eating makes some people more peckish than others, research shows.
Scientists found “big dippers” typically eat 312 more calories a day and wait half an hour less between meals than “little dippers”, leading to weight gain of up to 20lb annually.
It means some people feel hungry all the time and struggle to lose weight.
The study, by universities including King’s College London, monitored blood-sugar levels, glucose tolerance, sleep, activity and hunger.
