Do you know when you have finished lunch and yet you are still hungry all the time? One search can explain why our bodies think we’re still not satisfied even after a meal complete.

The research was published in Nature Metabolism and involves scientists from about five different institutions in Europe and the United States. The results show the reasons why some people are unable to lose weight even though they control the amount of calories consumed.


1.070 volunteers participated in the study. They were followed for two weeks. During the period, the group had to eat a breakfast standardized by the researchers, but I could eat other meals freely. In total, the volunteers consumed more than 8 thousand breakfasts and 70 thousand other meals.

Participants also took a fasting blood sugar response, glucose tolerance test to measure how well your body processes sugar. In addition, they even used glucose monitors all the time to measure their blood sugar levels. In one application the group also recorded the state of hunger and attention during the day. The standard breakfast consisted of muffins containing the same amount of calories, but varying in composition in terms of carbohydrates, proteins, fats and fibers.

The result showed that dipper patients, who suffer from high drops in blood pressure during sleep, experienced a 9% increase in hunger and ate an average of 30 minutes earlier than others in the same period of time. They also ate 75 more calories in the first three hours after standardized coffee and about 312 calories during the day. This may explain the difficulty in losing some of these people.

Previous studies focused on the first two hours after meals, where blood sugar spikes. Despite this, current research has shown sharp drops in the blood glucose level even after four hours after the peak. "Blood sugar levels have long been suspected to play an important role in controlling hunger, but the results of previous studies have been inconclusive," said Dr. Sarah Berry of King's College London.

Hunger all the time

“Now we show that sugar drops are a better indicator of subsequent hunger and calorie intake than the initial peak blood sugar response after eating, changing the way we think about the relationship between blood sugar levels and the food we eat ”, added the specialist.

“Many people struggle to lose weight and keep it off, and just a few hundred extra calories a day can reach several pounds of weight gain over the course of a year. Our discovery that the size of sugar after eating has a major impact on hunger and appetite has great potential to help people understand and control their weight and health in the long term, ”said Professor Ana Valdes, from the University of Nottingham School of Medicine.

No relationship was found between age, BMI and weight among the dipper participants. The results can help people find foods that work more warmly to their body biology so they don't feel too much and are satiated any longer.

“Food is complex and humans are complicated, but our research is finally starting to open the black box between diet and health. We are thrilled to have been able to turn this cutting edge science into a home nutrition and microbiome test so that everyone has the opportunity to discover their unique responses to food to better support their metabolism and intestinal health, ”concludes Tim Spector, professor of epidemiology genetics in King's College London.
