This bad dinner habit promotes the onset of diabetes and obesity

Having a healthy lifestyle can decrease the risk of developing diabetes and obesity. But this advice is not enough because certain habits can on the contrary favor these diseases. Among them: a bad habit at dinner. Find out which one.

Work schedules, outings, obligations … The lunch hour varies according to each person’s habits. Result? Sometimes eating late , which can disrupt sleep . But that’s not all: this bad habit would also increase the risk of developing diabetes or obesity . This is what a new study published in the Journal of Clinical Endocrinology & Metabolism reveals . To draw this conclusion, scientists at the American University John Hopkins first put forward a hypothesis.“We have assumed that eating a late dinner changes metabolism (…) in a way that promotes obesity . ” They then analyzed how the body metabolizes food based on dinner time.

Late dinner: blood sugar is higher and the amount of fat burned is lower

To do this, the researchers followed 10 healthy men and 10 women. Participants used to go to bed between 10 p.m. and 1 a.m. During this experience, the volunteers slept at fixed times: they went to bed at 11 p.m. and woke up at 7 a.m. the next morning. Scientists asked them to eat a meal at 6 p.m. one day, and the same dish at 10 p.m. another day. In these two situations, participants still had to go to bed at 11 p.m.

The results of this study revealed that the blood sugar level of the volunteers was higher at bedtime when the meal was taken late, at 10 p.m. Another finding of the researchers: the amount of fat burned was lower than when the difference between dinner and bedtime was five hours.

Dinner late increases the risk of diabetes and obesity

“On average, the glucose spike after late dinner was 18% higher and the amount of fat burned 10% lower” compared to the 6pm dinner, said Chenjuan Gu, lead author of the study. These metabolic changes were more pronounced in people who were used to going to bed early.

Conclusion: “late dinner induces nocturnal glucose intolerance” . In addition, this bad habit reduces the oxidation and mobilization of fatty acids , especially in those who sleep early. Researchers indicate that these effects could promote the onset of diabetes and obesity , if this habit is repeated over the long term. The reason is simple: the sugars and fats ingested do not have time to be eliminated by the body.

The scientists still pointed out that further studies, including a larger sample, would be necessary to confirm the results and observe if these effects persist over time. Other research would also determine if these effects are related to the behavior or the biological rhythm of each individual.
