Set your alarm! Eating breakfast before 08:30 can reduce the risk of developing type 2 diabetes.
- Previous studies have suggested that it is better to eat daily over a shorter period of time.
- U.S. researchers analyzed health and diet data on 10,574 U.S. adults
- They divided the subjects into groups based on the length of time they ate
- The team found insulin resistance was lower in those who only ate before 8:30 p.m.
Eating breakfast before 8:30 in the morning can lower your insulin resistance, reducing your risk of developing type 2 diabetes.
In people with type 2 diabetes, insulin that penetrates glucose and fuel cells does not work properly. Diabetics are at risk of serious health complications.
This can include damage to the eyes, heart and feet – in patients being treated for dietary changes, medication, weight loss and exercise.
Experts from the USA analyzed health and nutrition data on more than 10,500 adults to see how the timing and duration of daily consumption affect the risk factors of diabetes.
The work was inspired by previous studies that suggested that ‘eating time restriction’ – just eating for a shorter period of time during the day – improves metabolic health.

Eating breakfast before 08:30 in the morning can lower your blood sugar levels and insulin resistance, reducing your risk of developing type 2 diabetes.
“We found that people who started eating earlier in the day had lower blood sugar levels and less insulin resistance,” said author and endocrinologist Marriam Ali of Northwestern University in Chicago, Illinois.
This, she adds, was ‘regardless of whether they limited their food intake to less than 10 hours a day or that their food intake was spread over more than 13 hours daily.’
“With an increase in metabolic disorders such as diabetes, we wanted to expand our understanding of nutritional strategies to address this growing concern.”
In their study, the team analyzed data on the health and dietary intake of 10,574 American adults surveyed for the national health and nutrition survey.
They divided the subjects into six groups based on both their total food intake – less than 10 hours during the day, 10-13 hours and more than 13 hours – and whether they ate for the first time before or after 8.30 each day. is.
The researchers compared each group to investigate how the duration and timing of daily consumption could affect blood sugar levels and the estimated levels of inulin resistance.
The team’s analysis revealed that blood sugar levels did not differ significantly between the groups.
However, they found that insulin resistance was higher among those who ate over a shorter period of time during the day – and lower in all groups who started earning before 8.30 in the morning.
“These findings suggest that timing is more strongly associated with metabolic measurements than duration, and that it supports early eating strategies,” Dr Ali concluded.
The full findings of the study will be presented at ENDO 2021, the annual meeting of the Endocrine Society, which will be held virtually from 20 to 23 March 2021.
