Some people may be easily full just by eating a few mouthfuls of rice, while some people still feel hungry even after finishing a plate of rice. However, some are still hungry after 1-2 hours of eating. Why is that?
The PREDICT nutrition research team published a study in Nature Metabolism some time ago. The research reveals why people feel hungry quickly even though they have eaten a lot.
The combined research team from King’s College London and the ZOE institute of health sciences, found reasons why people have difficulty losing weight despite having a variety of healthy diets.
The study showed that people who experience a significant drop in blood sugar a few hours after eating, end up feeling hungrier and consuming more calories a day.
The study involved 1,070 participants. The research team also looked at the amount of food consumed by the participants over a period of two weeks. There were a total of 8,000 breakfasts and 70 thousand meals studied.
The average breakfast eaten contained the same number of calories from one participant to another, only differing in composition in terms of carbohydrates, fats, protein, and fiber.
Participants also took a blood sugar response test to measure how well the body processes sugar, then each participant also wore a glucose monitor (CGM) to measure blood sugar levels throughout the study.
Several previous studies revealed that blood sugar will rise within 2 hours of eating. This condition is known as the “peak blood sugar” period in the body. However, based on the research of the PREDICT team, some people experience a significant decrease in sugar 2-4 hours after the peak. Blood sugar levels drop dramatically to below normal before rising again.
Low blood sugar levels can cause hunger, even though you have actually eaten.
Most of the study participants experienced a 9 percent increase in hunger and waited, on average, about half an hour before returning to eating. Most of the participants also ate 75 calories more in the 3-4 hours after breakfast and 312 calories more each day.
“Our findings show that blood sugar levels that drop after eating have a major impact on hunger and increased appetite, thus making it difficult for a person to control their weight,” said one of the researchers, Professor Ana Valdes, quoted from King’s College London, Wednesday (14 / 4).
The researchers did not find a correlation between age and weight, on high appetite and hunger after eating. Although men tend to have a higher reduction in blood sugar levels than women.
Researcher who joined in the study, Patrick Wyatt of ZOE said his research could be valuable insight for others to understand their respective biological conditions. Choosing foods that suit your biology can help you feel full longer and eat less.
“By demonstrating the importance of sugar reduction, our study paves the way for those who want to manage hunger and calorie intake in the way the body needs,” he said.
