Feeling hungry all the time? Study confirms link to blood glucose levels

The interplay between blood sugar and appetite appears to be more complex than scientists realized, with new research showing that glucose levels in the blood even several hours after eating can still have a pronounced effect on how hungry people get later in the day. Specifically, the new findings reveal that some people are prone to experiencing ‘sugar dips’ up to four hours after eating their last meal – a delayed glycemic response that turns out to be a more accurate indicator of appetite (and energy consumption) than glucose levels following meals. “It has long been suspected that blood sugar levels play an important role in controlling hunger, but the results from previous studies have been inconclusive,” says nutrition scientist Sarah Berry from King’s College London.
