The Claim
In adults with overweight or obesity, a single day of late isocaloric eating increases 24-hour blood glucose levels by 3% compared to early eating, with a 9% greater increase during nighttime sleep, indicating that meal timing independently influences glycemic control when total caloric intake and macronutrient composition are held constant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with overweight or obesity, eating the same amount of food later in the day raises blood glucose levels by 3% over 24 hours compared to eating the same food earlier, with an additional 9% higher rise during sleep, showing that the timing of meals affects blood glucose independently of total calories or nutrients.
See the scientific wording
In adults with overweight or obesity, a single day of late isocaloric eating increases 24-hour blood glucose levels by 3% compared to early eating, with a 9% greater increase during nighttime sleep, suggesting that meal timing independently influences glycemic control even when total caloric intake and macronutrient composition are held constant.
When meals are eaten late at night, the pancreas releases less insulin right after eating, so blood sugar stays higher. At night, the body naturally becomes less sensitive to insulin, and eating then makes it harder for muscles and fat tissue to remove sugar from the blood, causing sugar levels to rise even more during sleep.
What the research says
1 studyWhen people with extra weight eat their meals later at night, their blood sugar stays higher all day and especially while they sleep—even if they eat the exact same food and amount as when eating earlier. This happens because the body handles sugar less efficiently at night.
