Researchers provided a breakfast containing standardized amounts of calories, and then allowed participants to eat what they normally would for the rest of the day, for a two week period.
Blood sugar levels were measured over the course of the study, and participants recorded their food intake and level of hunger.
Results: Despite eating the same breakfast meal, some people experienced major sugar dips, 2-3 hours later.
These people had a 9% increase in hunger and waited 30 minutes less before their next meal than the people who had smaller changes in blood sugar levels.
“Big Dippers” also ate 75 more calories in the 3-4 hours after breakfast and 312 more calories over the entire day than ‘Little Dippers”.
These additional calories could translate to a 20 pound weight gain over a year.
Individual differences in metabolism and insulin activity make a big difference to hunger and calorie intake.
